以南京市49个乡镇(街道)为评价单元,选取压力指标和状态指标构成农村环境评价指标体系, 利用GIS空间分析功能和矩阵聚类分析方法,对南京农村地区进行生态环境分区,将其分为综合环境优良 区、较好区和一般区3类,基于生态环境分区确定了重点环境整治地区和重点环境保护地区,并分区评述 了不同环境类型区的环境污染特征和环境保护战略取向。分区结果可为农村环境综合整治提供决策依据。 |

Abstract: |
Taking 49 towns and streets communities in Nanjing City as basic assessment units, and pressure and position two type factors as assessment index system, this paper divided the rural area of Nanjing City into three dif- ferent types areas, namely excellent environmental area, better environmental area and ordinary environmental area with the support of GIS spatial analysis and the method of claFssification matrix. The key environmental pollutant control area and the key environmental protection area were regionalized, and the feature of environmental pollutant and the strategy of environmental protection in different areas were also discussed. The result could provide basis for decision-making in rural environment protection. |
