Urban scale analysis From daofang bridge to songhua river, it is an urban fringe section, with farmland and river beach on both sides.The plan aims to provide urban residents with places to enjoy the natural scenery. From hexing bridge to daofang bridge, a number of small parks are planned on the basis of the original science park and children's park of Harbin Institute of Technology for the central area of the city, with the purpose of providing leisure places in the residential areas of the city. From the reservoir of industry and agriculture to hexing bridge, it is the fringe section of the city, and the two sides are mainly farmland and heilongjiang forest botanical garden, songjiang ecological park and northeast forest farm.

Site history
1920 As an industrial-dominated city, Harbin railwaywas built by the russians and transported by rail and by the majiagou river.
Site status analysis
1950-1960
1990
The site is owned by the railway authority and the Harbin Institute of Technology and is bounded by fu hua street.The west side of fuhua street belongs to the university of technology and the east side belongs to the railway bureau.
In the heyday of northeast China's industrial development, China railway group railway transported coal from surrounding areas to coal plants to accumulate coal mines for commercial trading. The former Harbin Institute of Technology property belongs to a textile factory, and the first-floor cottage area belongs to families of the railway bureau and employees of the textile factory.
Site status analysis
Now The industry declined, the textile factory closed down, the resources were exhausted, the land of the former textile factory was sold to Harbin Institute of Technology group, and the site of China railway group was leased to the driving school as a training ground.

The planning site of majiagou inland port ecological park is located on the bank of majiagou river in Harbin (from wenming street to tehua street), which occupies an important strategic position in the urban green space ecological network.The planning of the park aims to maximize the ecological value of the landscape under the framework of the urban green space network and play an important role of the site in the ecological corridor.The scheme promotes a virtuous circle among the ecological elements by balancing the relationships among human, plant, water, soil and animal subsystems.It emphasizes the positive influence of human "positive disturbance" on ecology, and creates a harmonious ecological environment in which human and natural systems are "strange and positive".

51years-? buffer zone core zone According to the site suitability analysis based on the data obtained from the site survey, the landscape pattern at the initial stage of site planning was determined. With the effect of artificial positive interference, the site underwent succession and merger. Multiple factors of the site are cycled and symbiosis. As time goes on, the landscape pattern of the site evolves, the core area expands step by step, and the human activity area gives way to other species, so that the site gradually forms a self-operating sustainable development mode.

The landscape composition of grassland gradually changed
The landscape began to mature and the grassland landscape gradually evolved towards the forest community. Dead large trees provide the best habitat for trees
The process of plant community expansion
This landscape feature is more representative of the local forest community.Trees of varying ages and the early succession of apoptosis provide an ideal forest habitat for wildlife.

Rainwater process management
Snowmelt process management
Flood process management
When there is rainfall, the rainwater in the site will gather according to the height difference and flow into the runoff, which will be filtered through surface flow wetlands and blind ditches or subsidence sand pools to purify the rainwater.
When the snow melts in spring, the snow water in the site will gather according to the height difference and flow into the runoff. This process will filter through the surface flow wetland and the blind ditch or the subsidence sand pool to purify the snow water.
When the rainfall is large, the runoff in the site and river cannot be discharged quickly, which will flood the beach along the river.The site itself has a large water storage emergency capacity.
Water purification process
Stratified residential land, poor soil, unable to grow plants
The missing topsoil was filled and repaired, and the consolidated soil was repaired by artificial loosening.
Heavy metal pollution and too little organic matter exist in the original soil of the site.
The use of specific vegetation roots to purify heavy metal pollution can also restore soil fertility.

Planning principles 1) Human activities should be used to stimulate the potential ecologicalvalue and promote the process of ecosystem improvement. 2) The value of ecological education on urban development should be emphasized. 3) The planning goal is to improve the urban ecological environment. 4) Directed by the natural succession of plant communities. 5) Take the diversity of animals as the evaluation criterion

② Changed water platform ——Waterfront landscape design of Shapowei Shapowei is the origin of xiamen port, since the qing dynasty as a haven. Shapowei is one of the streets jurisdiction over seven community of Xiamen port, adjacent to the south Putuo temple and xiamen university, its source is because this is the end of a long beach, and the sand flow to everywhere here. Early xiamen is a curved bay, bay in this area is crescent, together as a piece of golden beach, so have "jade ShaPo" laudatory name.

The design enriches the function of the site, and can well adapt to the natural environment.At the same time, it also breaks the original form of the waterfront trail, and integrates more Marine and fishery factors, so that people can better use the site, get close to the ocean, and feel the unique culture and history of the site.

The site can be used in different ways according to the water level of the sea, which can meet different forms of activities such as exhibitions, sports, entertainment and performances.At the same time, the vessels left over from the site can be combined in different ways, becoming an active factor in the unchanged site.In order to enrich the use of the site, adapt to the changes in natural conditions, but also to retain the traces of the site history.
