运用物元模型对江苏省苏南地区5个城市的土地生态安全进行了评价

结合区域特征分析苏南5市的土地生态安全随时间变化的趋势及其影响因素的区域差异

进而从总体上评价了苏南5市的土地生态安全动态变化。结果表明:(1)经济因素是促进苏南5市土地生态安全的主导因素

抑制因素表现出明显的区域差异

农药的使用严重威胁无锡、常州、苏州和镇江市的土地生态安全工业废气排放显著抑制南京市的土地生态安全

工业废水排放对苏州和无锡地区带来一定影响人口密度对苏南5市的影响也不尽相同。(2)总体来说

苏南5市的土地生态安全从2003年到2009年以稳步发展和跳跃式发展两种方式向较高等级转化

南京、常州和镇江地区的土地生态安全存在进一步优化的空间。

Abstract

The article evaluates the ecological security of land for five cities in Southern Jiangsu Province by matter-element model to present the trends of the ecological security and the regional differences of their influencing factors.The results show that:(1)The main factors promoting the ecological security of the land are economic factors while the negative factors vary from regions to regions:the use of pesticides brings great threats to Wuxi

Changzhou

Suzhou and Zhenjiang City;the industrial waste gas decreases the ecological security in Nanjing City;the industrial waste water has negative effects on Suzhou and Wuxi City and the high population density brings different threats to all five cites.(2)Uenerally

the ecological security of the land in the five cities were improved to higher levels from 2003 to 2009 either steadily or rapidly

and there is much chance and space for the situation in Nanjing
