摘　　要：开展城市绿化生态工程建设是保护城市生态环境、促进城市可持续发展的必由之路 .对城市绿化树种生态适应性及生态功能性相结合的综合评价 ,是构建城市生态工程、合理应用选择城市绿化植物的科学依据 .通过专家咨询评价的方法 ,从生态适应能力、绿化生态效益、美化效果、抗病虫害性、抗污染性、经济效益等方面全面系统地建立了沈阳市绿化树种生态功能与生态适应性评价应用的综合指标体系 ,并根据专家第一轮评价和沈阳市特定区域和范围 ,在对绿化树种的综合应用评价的基础上 ,选定耐寒性、耐旱性、耐瘠薄、抗病虫能力、抗污染能力、观赏性和生态效益 7项评价指标为主要的评价指标因子 ,对沈阳常见的 2 0 0种绿化树种进行了综合评判与分级 .评价结果表明 ,综合效能为 1级植物有 5 8种 ;2级植物为 93种 ;3级植物 38种 ;4级植物 11种 .Urban virescence eco-engineering is the core of urban eco-environmental construction,which can promote urban sustainable development.In urban virescence eco-engineering,the comprehensive evaluation of ecological adaptability and ecological effect of urban plants is the scientific basis of rational application and selection of urban garden plants.The ecological effect and integrative functions of urban virescence eco-engineering depend upon the selection and layout of garden plants.Using the methods of garden expert consultation and evaluation,this paper established systematically integrative evaluation and application indices of virescence plants in Shenyang City,from the aspects of ecological adaptability,ecological effect,beautification effect,resistance to plant diseases and insect pests,anti-pollution and economic results.According to garden experts evaluation and location of Shenyang,200 sorts of virescence trees were evaluated and classified on the basis of the comprehensive evaluation system of virescence trees,and using cold resistance,drought resistance,barren resistance,plant diseases and insect pests resistance,anti-pollution,ornamental quality and ecological effects as the indexes.The results showed that the number of first rank trees was 58,the second was 93,the third was 38,and the fourth was 11,ranked by integrative performance.
