建立贵州省农业非点源污染因子评价体系,最终对其进行污染敏感性评价。结果表明,贵州省农业非点源污染综合敏感指数为3.82,达到中度敏感等级;自然环境因子如土壤侵蚀、径流等是导致非点源污染的主要原因;贵州省农业非点源污染主要来源于重金属以及畜禽粪尿污染;贵阳市、黔南州是贵州农业非点源污染的主要敏感区域。
The evaluation system of agricultural non-point source pollution in Guizhou Province was established, and its pollution sensitivity was finally evaluated. The results showed that the comprehensive sensitivity index of agricultural non-point source pollution in Guizhou Province was 3.82, reaching a moderate sensitivity level. Natural environmental factors such as soil erosion and runoff were the main causes of non-point source pollution. The main sources of agricultural non-point source pollution in Guizhou Province In heavy metals and animal manure and urine pollution; Guiyang City, Qiannan Prefecture Guizhou Guizhou agricultural non-point source pollution is the main sensitive area.
