摘要
农业生态环境是保证农业生产的基本条件 ,本文在昆山市农业生态环境评价时选取了农业生产自然环境、农业生产投入、环境响应三个一级指标以及气候、降水等共 18个二级指标 ,对 1983年和 2 0 0 2年的农业生态环境进行了评价。结果表明 :昆山市的农业生态环境总体上处于良性状态 ,基本符合当地农业生产的实际情况 ;2 0 0 2年的农业生态环境较之 1983年有了一定程度的改善 ;主要是在农业生产投入方面更加的科学合理 ;生态系统的响应状况一般 ,土壤的重金属污染已经开始显化。
Agricultural eco-system environment is one of the most basic factors of agricultured Industry. To evaluate the eco-system environment, three aspects, which include 18 indices, such as temperature, precipitation, are selected. The results suggest the eco-system environment is in good condition both in 1983 and 2002. Compared with 1983, the eco-system environment condition has ameliorated to a certain extend. The regulation of agricultural investment contributes extraordinarily to the amelioration. The response shows the pollution of the soil begins to influence the agriculture eco-system.
