摘要
通过收集锦州市动物饲养量,推算其粪便量及其污染负荷,分析污染对土地承载压力的状况,并根据统计数据的粪便当量与标准当量的比值建立预警系统,并用地区实例加以验证预警模型,提出缓解家畜粪尿污染对土地承载压力的合理化建议。
This study collected data from Jinzhou city livestock breeding, calculated the amount of waste and pollution load, analyzed the current situation of pollution on the bearing pressure of land, and established early warning system based on the statistical data of the ratio of feces and standard equivalent. Early warning model is verified by regional examples, and some reasonable suggestions are put forward to alle- viate pollution of livestock manure on the bearing stress of the land.
