西南山区集约化畜禽养殖工程环境影响后评价指标体系构建

The Establishment of Environmental Impact Post-assessment Index System for Intensive Livestock Farming Project in Southwestern Mountainous Area

针对西南山区集约化畜禽养殖工程具有周边居民分布多、恶臭问题突出、山区环境容量相对较小、高浓度养殖废污水不宜排放的环境特点,归纳出此类工程在开展环境影响后评价过程中应重点关注资源环境承载能力、粪肥消纳区农田土壤污染、周边噪声污染、周边恶臭污染以及移民安置等几方面环境问题。通过核查对比DSPR模式、LCA模式和基本指标模式3类评价指标体系构建模式的方法特点,确定选用基本指标模式的技术方法初步构建了该类工程的环境影响后评价指标体系,对今后在该区域开展此项工作具有一定的指导意义。

Based on such environmental characteristics of intensive livestock farming project in southwestern mountainous areas as more environmentally sensitive target distribution, the stench problem, limited environmental capacity, prohibited discharge of high concentrated wastewater, the paper argues that the environmental impact post-assessemnt on intensive livestock farming project should focus on carrying capacity of resource environment, farmland soil pollution in manure given area, noise pollution, odor pollution and immigrants resettlement. Basic index model is chosen to establish the environmental impact post-assessemnt index system on the intensive livestock farming project, after comparing DSPR, LCA, and Basic index model. The index system can provide some guidance for future work in this area.
