摘要
开展宁夏灌区农业非点源污染的相关研究对保护黄河水安全具有重要意义。本文主要反映宁夏灌区上世纪90年代以来农业非点源污染现状的调查结果,揭示目前灌区的污染状况;同时对农业非点源污染形成的主要因素进行了分析,指出农田化肥、农药的不合理施用,畜禽养殖、农膜残留等均产生了不同程度的农业污染,随径流或排水进入黄河,造成水质恶化。
The research on ANSP in Ningxia irrigation district has a practical significance on pollution control and protection of the Yellow River water safety. Mainly through the investigation on ANSP in Ningxia irrigation district, it revealed the current pollution status in the district and analyzed the main factors of forming agricultural non-point source pollution. Then it pointed out that with the runoff or drainage into the Yellow River, different agricultural pollution from agricultural fertilization, pesticide application, intensive culture and plastic film, etc. resulted in deterioration of water quality.
