摘要
针对我国北方农业面源污染面积大、分布广、控制难的问题 ,通过分析新疆焉耆盆地水资源利用现状、潜水位动态、农田排水特征 ,认为大水漫灌不仅浪费水资源 ,造成肥料流失 ,降低产量 ,而且污染水体 ,导致土壤次生盐渍化 ;提出了推广节水灌溉、合理开发利用水资源、控制农业面源污染、综合治理环境的有效途径。
Agricultural pollution is widely found and difficult to be controlled. Based on the analysis of water utilization, water table fluctuation,farmland drainage in the representative area of Yanqi basin, it is concluded that over irrigation will not only waste water, leach fertilizer and decrease crop production, but also pollute surface and groundwater and lead to soil salinization and water logging. Therefore,the authors have put forward effective measures to control agricultural pollution and synthetically remedy and improve the environment by water saving irrigation and rational water development.
