Due to food pressure, grain product in the western Jilin Province will be enhanced in the near future. Farmland areas in the area will be decreased slowly in the near future, but with the technique development of irrigation establishment, paddy areas and utilization amount of fertilizer and pesticides will be increased rapidly. So, the NPS pollution from farmland will be more serious. The main lakes in the areas such as Moon Lake and Qagan Lake have been polluted by N and P, and the content of salt in the Nenjiang River has been increasing since last 30 years. All of these show that the negative effects of NPS pollution in the area have been serious and should not be neglected by the scientific research and corresponding government management. To deal with the contradiction of agriculture development and water pollution, the trend of increasing paddy area and using amount of fertilizer, pesticide and herbcide in the western Jilin Province should be controlled. Also, the drainage of return flow from paddy should be controlled and return flow should be disposed with ecotechniques by use of the large areas of lakes and mires in the area. Through these measures, the quality of surface water could be protected and the degeneration of ecoenvironment in the area could be contained.

我国由于粮食压力，未来吉林西部的粮食生产还将进一步加强，随着种植业结构的调整，垦殖率会略有下降，但随灌溉设施的建设与完善，水田面积将进一步扩大，化肥、农药的用量还将快速增加，农业活动引起的非点源污染将更加突出，而研究区的主要湖泊月亮湖、查干湖目前已达中等富营氧化水平，嫩江水质的咸化趋势明显，因此农田非点源污染物的流失及其内流区外流化面积的增加对地表水体富营养化、咸化的作用愈来愈明显，农田非点源对地表水水质的影响已不容忽视，应引起社会的关注，为协调农业发展与水污染这一矛盾，吉林西部应遏制化肥、农药施用量增长过快和水田过度开发的势头，控制洗盐回归水的排放量，利用区内广泛分布的大量泡沼对农田径流和回归水进行生态处理，既保护了地表水的水质，又有利于生态环境的改善。
