摘要/Abstract

摘要： 以南京市城市环境为例，从生态学的角度分析城市生态环境系统的主体、重点，确定与城市生态环境相关的评价指标，通过评价指标的层次化处理，建立城市生态环境评价的指标体系，阐述了该指标体系的作用和意义。采用层次分析法确定各评价指标权重，计算评价指标体系的综合评价值，根据综合评价值的大小划分城市生态环境质量的等级。统计结果显示，评价结果与南京市生态环境的实际状况基本相符，南京市生态环境质量在总体上呈逐步改善的趋势，环境污染状况明显改善，但是自然环境在逐渐恶化，主要是自然灾害的影响。本研究对开展我国城市环境生态化水平的评价以及生态城市的创建具有实践指导意义。

Abstract: From the viewpoint of ecology,this paper analyzed the principal part and major points of urban ecological environmental system in Nanjing,and established the evaluation indices related to the ecological environment.By layered processing the evaluation indices,the indiecs system of urban ecological environmental quality was established,and the significance and function of this system was explained.Analytic Hierarchy Process (AHP) was applied to judge the weight of each evaluation index,and to calculate the comprehensive assessment values of evaluation indices system.The urban ecological environmental quality level was graded according to the comprehensive assessment values,and the results were actually coincided with the situation of Nanjing.Overall,the ecological environmental quality of Nanjing was improved step-by-step,the environmental pollution was obviously lessened,but the natural environment was gradually worsened,especially under the influence of natural disasters.This study established an effective method for the ecological evaluation of urban environment,which would benefit to the establishment of ecological cities in China.

Key words: Broadleaved Korean pine forests, Eco climatic suitability, Temperature water effect function, Climate change, Assessment
