| 摘 要： | 从农村工业污染、农业面源污染和农村生态服务价值变化三方面出发,构建农村生态环境压力指标,以省(市)为核算单元,利用突变级数模型定量评价1990-2006年间农村生态环境压力,并分析农村生态环境压力的时空分异特征。研究结果表明:1)1990-2006年间农村发展对生态环境的压力逐步增大,农业面源污染和农村工业污染对生态环境的压力占主导地位;2)农村生态环境压力相对较大的地区主要分布在农业集约化程度较高、农村工业较发达、人口众多的地区,如浙江、湖南、广东、四川、河北、河南、江苏和山东等省市。3)不同区域农村生态环境压力的来源差异也较大,因此不同区域应据此实行差别化的管理措施。

| Abstract: | Based on provincial(municipal) statistics,this research applied the Catastrophe progression model to evaluate the rural ecol-environmental stress in rural China from 1990 to 2006 and analyzed the spatial and temporal characteristics of rural ecol-environmental stress.Results indicatd that during 1990-2006,the index of environment stress was increasing gradually.The high environment stress areas were those provinces with intensive agriculture,developed rural industry and large population,such as Zhejiang,Hunan,Guangdong,Sichuan,Hebei,Henan,Jiangsu and Shandong.On the other side,the sources of environment stress of the above provinces were quite different.It is therefore implied that different management measures should be conducted in different regions. |
