Central Business District

Hong Kong Island

The Cochrane Sitting-out Area, surrounded by the mixed-use high rise building and a construction site, is located at the steep Cochrane Street under the Central-Mid-Levels escalator. The Street and the escalator is the primary connection between the Mid-Levels residential area and the Central commercial area. Thousands of residents, office workers and visitors of historical buildings like the Tai Kwun Museum pass by the Street and the escalator. The Street was initially a Cantonese residential area in the 19th century and slowly developed into a mixed-use district with high rise buildings. The sitting-out area was replaced by the original food and grocery stalls to provide more leisure spaces and space for the pedestrian road. The Central-Mid-Levels escalator has operated since 1993 to improve the traffic and became a tourist attraction with restaurants and bars on the Cochrane under it.

该室外休憩区位于香港岛中环商业区的阁麟路上，其顶部为中环半山扶梯。尽管有半山扶梯存在，这处场 地的人流通行密度并未受到影响。根据统计，从上午9点到晚上8点有近18000人通行此处。中环地区作 为香港最繁荣的商业区之一，该场地在18世纪原为老式广东社区，后来逐渐发展成现在的综合商业区， 场地呈西南东北走向，东南角与东北角伫立高75m的大厦，场地东侧为老式6-8层平房，下层主要用于商业，包括茶馆、餐饮、服装等， 西南角为便利商店，西侧主要区域尚未开发，中间保存有四颗大型乔木。

The sitting out area is the only public rest site for this 1km radius district. Therefore people are always intended to come here for rest, such as taking lunch, drinking a bottle of caffee, smoke a cigarette or just take a nap at their lunch break. At the same time tourists would come here for a rest since there's little area for tourists to rest. On workdays the site is filled with white-collers, blue-workers from the near constrution site and some elders. But at weekends, the Filipino domestic helpers are the primary users of the space. They often occupy different areas in groups of 3 to 5 people. As observed in other locations in Central district, this active women community spends most of their day, often until evening, eating home-cooked food, chatting and dancing. In the evening, teenagers animate the space chatting and drinking beer purchased from the nearby convenience stores. In a word, no matter it's a workday or a day-off, the site is highly occupied.

此处为周边1公里范围内唯一的休憩空间，人们抵达此处的目的性极强，在午餐时间，原有场地上设置 的长椅是人们在午休时间吃午餐、喝咖啡或者小憩的热门场所。同时游客也会来到这一区域休息，这也是 因为中环地区公共休憩空间较少导致的。平日里使用此处的人群主要是附近上班的白领，工地里的工人 以及一些老年人。周末的时候，菲律宾籍的佣人成为这里的主要适用人群。他们通常三五成群占据此处的长椅等空间聊天聚会，吃自制食物， 跳舞唱歌，这是他们周末休假放松的重要场所；而到了晚上，附近的年轻人人会来到此地，喝着从附近便利店买来的啤酒饮料，聊天聚会。

因此，不论工作日或假期，此处的人群使用频率都较高。

The competition aims to modify the old house and design a homestay with its auxiliary space to attract tourists in the Jing'an County, Jiangxi Province. The site located near the San Zhualun National Forest Park. Abundent of greens and countryside scenes, the modification needs organize these elements to a aethetical landscape. The former house is semi-enclosed with the southern side open. The left three sides are surrounded by trees and bushes, accounting of bad views inside. The former shape was adopted and the structures were reused to lesen construction cost. With a modern design way and combining former and newly material like steels, glass and wood panels, the house is lifted from its site but at the same time the site set its views and create landscape for it.

此次竞赛的目的是改造位于江西省靖安县内指定的一处旧房并且设计周边的附属景观打造为民宿以吸引旅客。场地位于江西靖安三爪仑国家森林公园边。这次改造在景观方面需要 重新组织设计场地周边丰富的植被以及乡村风光成为具有审美特征的景观。原有建筑为一个半包围式的三合院，只保留南侧开敞。剩余的三侧均被绿植包裹，因而建筑内景观视野 较差。原有的建筑形式被保留下来，同时原有的部分结构被重新利用从而减少建设成本。通过现代设计手法并将原有材料与新的材料包括钢材、玻璃以及各种特征的三合板结合， 新的民宿建筑创造出在附近地区的飞地的同时利用周边的田园景象丰富建筑本身的景观

Use the local material granite to create landscape in the south court, the guest room has the best landscape view with an artificial landscape to natural landscape.

In the façade treatment, the ground floor building is wrapped in concrete with bamboo formwork according to the functional needs, and windows are opened in the local functional areas to provide light, while the first floor overhanging corridor area is enclosed by a special floor-to-ceiling glass curtain wall system to ensure the overall permeability of the upper floor space, while U-shaped glass is used locally according to the functional needs to achieve private space and light avoidance. Combining the current situation of the site, the southeast corner of the main hotspot of pedestrian flow is used as the main entrance. In the structural axis, a diagonal axis is added to the main axis of the site to retain the original activity flow of the site while increasing the contact of pedestrian flow in the site and improving the possibility of site utilization.

在立面处理上，地面建筑根据功能需要通过竹制模板混凝土包裹，局部功能区域开窗提供采光，而二层悬廊区域通过特种落地玻璃幕墙围护系统保证上层空间整体通透性，同时在局部根据功能需要利用 U型玻璃实现私密空间与避光需求。 结合场地现状，将东南角人流主要热点区作为主入口，在结构轴线上在场地主要轴线基础上添加斜传轴线，保留原先场地活动流线的同时使人流在场地中增加接触，提高场地利用可能性，在二层悬廊设计上，竖直方向错落的高差让内外建筑都能拥有良好的 对外视野，并提高建筑采光率。

Historical Heritage Analysis / 基地范围内历史遗产分布

Historical Resource of the Eco-Innovation zone / 绿创社区空间资源分布

The planning base is located on the east side of the central part of Fuxing Island, which is part of the central core area of the Green Creative Community in the master zoning plan, bordered by the Huangpu River on the east and Gongqing Road on the west, the city;s living room on the south and the city's wild heart on the north. The total area of the base is 25 hectares, inclluding a water area of 4 hectares. The area of the design base basically belongs to the former Hudong-Zhonghua Shipyard area, where a large number of historical buildings and production machinery and tools of the shipyard have been preserved. The most prominent part of the site is the original shipbuilding platform in the centre of the site, A shipyard full of industrial production and manufacturing history has been lost to the city with the exparsion of the Hudong Shipyard and the strategic retention of Fuxing Island.

The overall planning strategy unfolds from the word 'anchor': in the overall spatial layout, one axis leads through the original ship platform axis to create the core landscape axis; Four points of anchoring, by preserving and transforming the original shipyard's main historical heritage as the main nodes, forming anchor points distributed in the four directions of the base, controlling the two main axis directions of north, south, east and west, so that the overall structure is spatially echoed through the anchor points; multiple axes interspersed: connecting the north side of the research and living area on the north side and the entrepreneurial work area on the south side are connected through a variety of efficient peer corridors, forming two different spaces for work and leisure passage experiences, and fixed on both sides of the central core area. The overall landscape structure consists of a landscape corridor perpendicular to the surface of the river and a landscape slow walking system that gradually unfolds from the hinterland to the riverfront, creating riverfront nodes with different landscape views on the riverfront through vertical design, all of which introduce people to history, to the riverfront and to nature through the overall boat anchor structure, creating an ecological and innovative core area that can attract talent and simulate innovation through a rich and diverse landscape space full of history and culture 生态整体规划策略从“锚”这一名词展开：在总体空间布局上以一轴引领，通过原有船台轴线打造景观核心轴；四点锚固：通过保留并改造原有船厂主要历史遗产为主要节点，形成分布于基地四个方向的锚点， 控制南北、东西两个主要轴线方向，使整体结构通过锚点在空间上产生呼应；多轴穿插：将北侧的科创生活区与南侧的创业工作区通过多种效率的通行走廊链接，形成工作、游憩两种不同的通行空间，并 固定在中央核心区两侧。

整体景观结构通过垂直于浦江江面的景观通廊和腹地向滨江逐渐展开的景观慢行系统组成，在滨江上通过竖向设计打造不同景观事业的滨江节点，均通过整体船锚结构将人们引入历史，引入滨江，引入自然， 通过丰富多样而富有历史文脉的景观空间，创造出足以吸引人才并激发创新活力的生态创新核心区

长江口潮滩生境变化影响因素――潮滩生态系统

Factors influencing aquatic habitat change in the Yangtze estuary

Tidal flats ecosystems

当前潮滩生态系统组成上，典型断面特征呈现从高潮滩，中潮滩，低潮滩，浅水区到深水区的五级过渡，在比例分布上，以中潮滩占主导，低潮滩其次，最后是高潮滩，其中中低潮滩在日常涨落潮期间均有可能被淹没，因此成为潮间带；其中值得注意的是潮间带区域特别 是中下潮滩是大量鸟类及底栖动物的重要栖息地，同时也是鱼类的幼鱼重要觅食及生长区。在植被分布上，高潮滩以芦苇为优势种，中潮滩较高区域以外来入侵物种互花米草为主，中下部分则以更抗湿的海三薐藨草占主导，低潮滩植被较少，主要为海三薐藨草。

In terms of the composition of the current tidal flats ecosystem, the typical cross - sectional characteristics show a five - level transition from high tide flats, middle tide flats, low tide flats, shallow water to deep water, in terms of proportional distribution, the middle tide flats dominate, followed by the low tide flats and finally the high tide flats, where the middle and low tide flats may be submerged during the daily high and low tides, thus becoming the intertidal zone. It is worth noting that the intertidalzone, especially the middle and lower tidal flats, is animportanthabitat for a large number of birds and benthic animals, aswell as animportantfeedingand growing area for juvenile fish.

未来不利因素影响下潮滩生态系统变化

Changes in tidal flats ecosystems under the influence of future

在由于上下游以及河口本身水文因素变化影响，未来长江口区域的潮滩生态系统将发生剧烈改变，一方面由于海平面上升以及河道收窄导致的局部水动力增大，河口潮滩坡度将变得更为陡峭，同时中低潮滩占总潮滩比例将严重下降，虽然中潮滩比例占比仍然出于最高， 但由于海平面上升及潮滩坡度变抖的影响，中潮滩将更容易被互花米草占据，由于中潮滩较低区域减少，大量鸟类以及其他底栖动物生境损失殆尽，同时驳岸区域浅水区减少也将导致相应幼鱼丧失生存环境，这将严重影响潮滩生境系统生物多样性及稳定性，同时不断 收窄的潮滩也将给内堤海防带来更大压力，其抵抗风暴潮韧性将急剧下降。

The tidal ecosystem of the Yangtze estuary will change drastically in the future due to changes in hydrological factors upstream and downstream as well as in the estuary itself. This will seriously affect the biodiversity and stability of the tidalhabitat system, and the narrowing of the tidal flats will put more pressure on the inner dykes and their resilience tostorm surges. Storm surge resilience will be drastically reduced

从上世纪 50 年代开始，长江主干上中游区域及重要 支流区域修建了大大小小上万个水利工程，对长江口 来水来沙产生了巨大影响。

从泥沙收支角度，根据研究分析当长江口大通水文站 检测泥沙（橙色粗线）小于 105Mt/a 时，将导致河口 区域泥沙收支失衡，从而产生侵蚀； 从水文来水量角度，根据研究分析当长江口大通水文 站检来水（橙色粗线）小于 900km3/a 时，将导致较 为严重的盐水入侵，从而影响河口相关水库取水安全。

围垦现状及未来冲淤特征

Upstream water comes to sand age change

在围垦情况上，自上世纪 70 年代以来，包括启东东侧， 崇明三岛，太仓以及浦东东部南汇等区域都有进行 大规模的围垦活动，在时空分布上，1990 - 2008 年 之间是滩涂围垦的高峰期，大量的滩涂在这阶段被 围垦开发利用，包括崇明东滩，北湖周边，以及兴建 的青草沙水库，横沙岛东滩以及南汇东滩等主要区 域，一方面围垦是为了获得更多的土地资源，但同时 围垦也带来了包括滩涂湿地锐减，驳岸坡度陡增影 响海防安全等不利因素。

在未来冲淤特征上至 2035 年长江口总体上将以冲 刷为主，尤其口内河段主槽和沙体边缘冲深较明显， 少数浅滩局部区域有所淤积。北港口外和南北槽口 外水下三角洲冲刷带维持冲刷态势。长江口前缘四 大潮滩呈现不同的演变趋势，崇明东滩整体冲刷，但 东滩浅滩在东侧继续拓展；北港口外和南北槽口外 水下三角洲冲刷带维持冲刷态势。长江口前缘四大 潮滩呈现不同的演变趋势，

在区域分布上，从来水分配中南支水流量将进一步 增大，同时南港水流量将增加，而北港将减少，这将 导致咸潮回溯时，对北港影响增加，而南港及北支 均减少

而在泥沙收支情况中，根据研究整体上除了崇明东 滩有相应的泥沙淤积，其他区域整体上呈现冲刷大 于淤积的情况，从而导致每年有约 206Mt 泥沙从长 江口流失。

In terms of the constructionprocessand working principle, thesand will first be extracted andtransported from the surrounding mineable area by sandmining vessels, which will form an initial water storage sandbar. During the flood season, along with increased upstream water and rainfall, the water level of the sandbar will be higher thanthe outer water level; during the dry season, along with salt water intrusion, the water storage sandbar will release fresh water to alleviate the return of salty tides, and the artificial sandbar wetland will replenish the lost tidal flats and create new tidalhabitats. It is expected that in the future the sandbar will provideimportanthabitat for a wider range of flora and fauna.

长江口干旱期主要集中在每年 12 -次年 4 月，伴随着上游来水减少，海面咸潮回溯，整个 长江口水域咸度均有较大上升，为了应对这些不利因素，人工沙洲通过释放储存的淡水， 在咸潮入侵严重的时期或上游来水渐少超过阈值的日期释放淡水资源，调节水域咸度， 保护下游的青草沙水库等取用水安全以及相关环境水生境稳定。

The dry period in the Yangtze estuary ismainly from December to April each year, accompanied by a decrease in water coming from the upper reaches and the return of salty tideson the sea surface, resulting in a significant increase insalinity throughout the Yangtze estuary waters. To cope withthese unfavourable factors, the artificial sandbar regulates the salinity of the waters by releasing stored freshwaterresources during periods of severe salty tide intrusion or when the water coming from the upper reaches gradually exceeds the threshold, to protect the safety ofwater intake from the Qingcaosha Reservoir and other water habitats in the related environment downstream.

河口固沙消浪沙洲建设规划

沙洲水土保持专项规划

Estuarine sand fixation and wave mitigation sandbarconstruction plan

在建设流程与工作原理上，与上游沙洲类似：首先通过采砂船将周边可开采区域泥沙开 采运输，采砂船作业形成初始固沙消波沙洲，上游来沙中未能被长江口区域潮滩固定的 泥沙将在此处再次被捕捉，同时海面上的风浪在进入喇叭口前会在人工沙洲上消解或减 弱，以减少其对内部潮滩的冲击。人工沙洲湿地将补充损失的潮滩，产生新的潮滩生境。 可以期待未来储水沙洲将为更多动植物提供重要栖息生境。

In terms of constructionprocessand working principle, itissimilar to the upstream sandbar: firstly, the sandis extracted andtransported from the surrounding mineable area by sandmining vessels, which operatetoform an initial sand fixing and wave dissipating sandbar, where the incomingsand from the upstream that has not been fixed by the tidal flats of the Yangtze estuary area will be captured again, while the wind and wavesfrom the sea will be dissipated or attenuated on the artificialsandbar before entering the trumpet to reduce its impact on the internal tidal flats. The artificial sandbar wetland will replenish the lost tidal flats and generate new tidalhabitat. It can be expected that in the future the storage sandbars will provideimportanthabitat for a wider range of flora and fauna.

长江口潮汛期主要集中在每年 7- 11 月，伴随着上游来水的增加，上游来沙量也会增加，根 据研究数据，，从入海口上下两处区域来沙量最大，也是河口固沙沙洲的重要捕捉面，泥 沙将会由于人工沙洲的阻挡以及后续种植的固沙植物的帮助下在河口固定下来，促进沙 洲生长。

According to research data, thetwo areas above and below themouth of the estuary, where the most sand comes in, are also important capture surfaces for sand - fixing bars in the estuary, where the sediment will be held in place by artificial sand bars and subsequent planting of sand - fixing plants to promote the growth of sand bars

长江口设计建设的固沙消浪沙洲将有效地抵挡来自海面的风浪，削弱其对河口内部沙洲 及潮滩生境的影响，同时这些风浪也给河口沙洲迎风面带来一定的淡水资源，以维持其 植物生境所需。

The sand and wave - fixing sandbars designed for the estuary of the Yangtze River will effectively resist the wind and waves from the sea, reducing their impact on the sandbars andtidal flats habitats withinthe estuary, while these wind and waves will also bring some freshwaterresources to the windward side of the estuary sandbars to maintain their planthabitat requirements.
