引黄工程对灌区环境和土壤的影响

Effects of Irrigation Area of Yellow River Diversion Project Environment and Soil

本文以1998年东雷二期引黄工程富平灌区投入运行以来的数据为基础,从水资源对灌区生态环境的影响入手,研究表明:多年的灌溉使灌区植被覆盖明显提高,土壤质量显著改善,盐碱土地逐步缩小,作物耕种次数和种类增多,灌区地下水得到补充,水位逐年提升,灌区生物种类明显增多。引黄工程极大地改善了当地的生态环境,对干旱少雨的渭北可持续发展具有重要意义。

Since 1998 the Yellow River Diversion Project Phase II,Fuping Irrigation put into operation,the impact on the ecological environment of water irrigation start,years of irrigation irrigated vegetation cover significantly improved significantly improve soil quality,saline land gradually reduced,the number and type of crop cultivation increased irrigation groundwater replenished,the water level increased year by year,species irrigation increased significantly. Greatly improved the local ecological environment,sustainable development of drought Weibei proposed guiding opinions.
