三江平原总面积１０．９万ｋｍ２,有大小河流１９０余条。全区地表水资源１３５亿ｍ３,地下水储量７５．１亿ｍ３,三大江多年平均过境水量 ２３００亿ｍ３,水质良好,适于工农业用水和生活饮用。随着工农业生产的发展和城市人口的不断增加,工业废水和生活污水也日益增多,也严重污染了水体。该区水旱灾害频繁,水土流失现象较为严重,湿地面积缩小,给工农业生产和人民生活带来了严重危害。本文提出了建立水生态环境保护体系、加强环境监测、保护水源,加大水利投入、推广节水措施等对策。
Sanjiang Plain a total area of 109000 km2, there are more than 190 rivers and streams. The region’s surface water resources of 13.5 billion m3, groundwater reserves of 7.51 billion m3, the three major rivers for many years the average cross-border water volume of 230 billion m3, good water quality, suitable for industrial and agricultural water and drinking. With the development of industrial and agricultural production and the continuous increase of urban population, the industrial wastewater and domestic sewage are also increasing day by day, which also seriously pollute the water body. Floods and droughts in the area are frequent, resulting in serious soil erosion and shrinking wetland areas, which have brought serious damage to industrial and agricultural production and people’s livelihood. This article puts forward countermeasures such as establishing aquatic ecological environment protection system, strengthening environmental monitoring, protecting water resources, increasing investment in water conservancy, and promoting water saving measures.
