Abstract Taking ornamental value, economy, culture, resistance and adaptability as evaluation index, we identified 19 evaluation factors based on expert consultation and market research then used them in analytic hierarchy process to make integrated assessment of 12 rare tree species in Changxing County. There are 3 species (Ginkgo biloba, Zelkova schneideriana and Pistacia chinensis) suitable for afforestation on plain and 2 species (Betula luminifera and Phoebe chekiangensis) for mountains. This afforestation evaluation system for rare tree selections we established has its practical significance for forestry production and the development of rare trees resources. Keywords: Rare Tree; Index System; Analytic Hierarchy Process; Integrated Assessment

珍贵树种筛选造林评价体系的构建与应用研究 沈泉 1,陈海 1,孙亚光 1,周泓 2 1. 长兴县林业局绿化造林科,浙江 湖州 313100 2. 浙江大学园林研究所,浙江 杭州 310058 要:以观赏性、经济性、文化性、抗逆性、适应性五方面为评价指标,在专家咨询和市场调查的基础上,确定了 19

个评价因子,运用层次分析法对长兴现有的 12 个主要珍贵树种进行了综合评判。从中选择出可以在本地区推广平原造林 的 3 个品种:银杏、榉树、黄连木;推广山地造林的 2 个品种:光皮桦、浙江楠。初步建立了珍贵树种筛选造林综合评 价体系,对于指导林业生产实践,进一步推动珍贵树种资源的发展,具有现实意义。 关键词:珍贵树种;指标体系;层次分析法;综合评价

引言 珍贵树种具有很高的经济价值、观赏价值,并具有特殊的用途,是经济社会发展特需的战略资源,又 是农民增收致富的重要发展资源。长兴县位于浙江省最北端,地处苏浙皖三省交界处,东临太湖,气候湿 润,土壤肥沃,是浙江省珍贵树种种质资源较为丰富、分布较集中的县区之一,且苗木产业发达,产业面 积达 27.1 万亩,规模居浙江省首位,发展珍贵树种资源条件优越。但由于苗农普遍对珍贵树种的特性、市 场情况等认识不到位等问题,目前,还存在规模小、分布散、结构不尽合理等问题。因此,通过对珍贵树 种筛选造林评价体系的建立,对现有珍贵树种进行综合评价和排序,为长兴县推广造林筛选最适宜的品种, 对于科学发展珍贵树种资源、促进我县森林质量提升、苗木产业结构转型升级,增强可持续发展能力具有 重要的现实意义。
