吉林省西部水环境改善探讨

Water environment improvement in western part of Jilin Province

吉林省西部水环境恶化,干旱日趋严重,土地荒漠化、盐渍化进程加快,牧草退化,湿地萎缩,生物物种减少,使得农业生产的不稳定性加剧。通过对该地区水环境现状的研究,提出了相应的改善措施,即利用流经吉林省西部地区境内的嫩江、洮儿河和霍林河的天然过境水和洪水,以及三大灌区的回归水,充盈星罗棋布的泡塘,扩大水面面积和湿地面积,从根本上解决吉林省西部地区水环境恶化的问题。

Agricultural production has become increasingly unstable due to the worsening of water environment,drought disasters;speeding up of land desertification and saline and alkaline,degradation of grassland,withering of wetlands and reduction of biological species.Relevant measures are proposed based on study of current situation of local water environment,such as using trans-boundary rivers and floodwater of Nenjiang,Taoerhe and Huolinhe,as well as return water from three large irrigation districts,for recharging ponds and areas of wetlands,and finally alleviating the pace of water environment degradation in the western part of Jilin Province.
