摘要:

农业面源污染已成为我国重要环境污染源之一,但由于农业面源污染具有分散、面广、周期长、随机性等特点,在评价上存在较大难度。根据生态效率理论,结合农业生产的特点,建立了综合考虑经济效益和环境影响的农业生态效率评价指标体系,并以江苏省无锡市为例,选取该市1998~2008年农业生产和面源污染相关数据,运用偏好锥的数据包络分析模型(DEA)对其农业生态效率进行了评价分析。结果显示:1998~2008年,无锡市农业生态效率呈现先下降后上升的趋势,近三年累计上升幅度达22%。表明近年来无锡市农业面源污染治理成效显著,农业可持续发展水平显著提高。提出的农业生态效率评价体系和方法为进一步推进农业面源污染治理工作提供了依据

Abstract:

In recent years,agricultural nonpoint source pollution has become one of the main pollution sources in China while there were few quantitative evaluations and researches on it.Based on the theory of ecoefficiency and the characteristic of agricultural production,this study designed an evaluation indicator system for agricultural ecoefficiency by integrating economic profit factors and environment impact facts.Using the restraint coneratio data envelopment analysis model,the agricultural ecoefficiency in Wuxi City,Jiangsu Province from 1998 to 2008 was evaluated on the basis of the relative data.The results showed that the agricultural ecoefficiency in Wuxi City appeared to be decreased initially and thereafter to be increased.The value had increased by 22% since 2006,which was primarily due to the significant decrease of chemical fertilizer and pesticide consumption.The evaluation indicator system and evaluation method in this paper would provide a mathematic tool for controlling agricultural nonpoint source pollution and improving agricultural ecoefficiency in China
