在前人研究的基础上,针对目前土地利用规划环评指标问存在的信息重叠问题,以安徽省当涂县为例,运用SPSS软件基于相关性分析探讨了土地利用规划环评指标体系的建立,并在此基础上运用综合指数对当涂县土地利用规划方案进行评价。结果表明:(1)基于常用的指标体系建立思路(环境影响识别一确定指标体系构建原则一建立指标),增加原始指标定量筛选环节,将能有效避免指标间信息重叠现象的产生,指标的独立性更高;(2)2005年当涂县土地利用规划环境影响评价综合指数为0.7341,环境、资源、生态及社会经济分项指数分别为0.2596、0.0993、0.1657、0.2095。规划方案实施后,到2020年全县环境、资源、生态及社会经济分项指数分别为0.3046、0,1072、0.2560、0.3272,均有不同程度的提高,规划方案可行。
Due to the indicators overlap of the information in planning EIA of land use, SPSS software combined with method of correlation analysis was chosen to assess environmental impact of land use planning in Dangtu County, Anhui Province. Environmental impact assessment index system of land use planning was built, and results showed that the indicators selection based on correlation analysis can avoid the omission of important indicators and information overlap between indicators, and the indicators are more independent. Combined index of the County in 2005 is 0.734 1, environmental, resource, ecological an.d social index are 0.259 6, 0.099 3, 0.165 7 and 0.209 5 separately. After the implementation of land use planning in 2020, environmental (0.304 6), resource (0.107 2), ecological (0.256 0) and social index (0.327 2) will increase, the planning is feasible.
