江苏省区域农业生态环境质量的时空变异分析
Temporal and Spatial Change on Eco-environmental Quality of Regional Agriculture in Jiangsu Province
摘要
Abstract
The reasonable of evaluation index system was analyzed using the principal component analysis,and the models for assessing the agricultural and eco-environmental quality were established,in order to assess the spatial and temporal variability of agricultural and eco-environmental quality about different economic zone in Jiangsu province.The results indicated that：（1）The agricultural and eco-environmental quality index of Xulian,Yanhai,Ningzhenyang,Yanjiang and Taihu decreased from north to south of Jiangsu province for 1995,2005 and 2008,and Xulian economic zone was the highest,Yanjiang,Yanhai,Ningzhenyang were the second,Tai lake was the lowest.The indexes of agricultural and eco-environmental qualitities in 5 economic zones decreased obviously as time went by.（2）Taken Xulian and Tai lake economic zone（Pizhou and Xinyi,Zhangjiagang and Jiangyin） which have the highest variations of the agricultural and eco-environmental quality for example,in order to assess the dynamic changes of agricultural and eco-environmental quality.The agricultural and eco-environmental quality of Xulian and Tai lake decreased from 1999 to 2008,and the agricultural eco-environmental quality of Xulian economic zone was much better than that of Tai lake.The agricultural and eco-environmental quality was different between the cities which belong to the same economic zone.The agricultural and eco-environmental quality of Xinyi was kept in good level from 1999 to 2003,and Pizhou had a highest starting point,but reduced rapidly from good condition to general condition,and now even worse.The agricultural and eco-environmental quality of Zhangjiagang and Jiangyin was worse than Pizhou and Xinyi,which always maintains in general level with small fluctuation.So the agricultural and eco-environmental quality will be different in different regions,even in the same economic zone.Adopt the suitable countermeasures about the specific conditions of different cities,when people were concerned about agricultural and eco-environmental quality of all cities.关键词
