商丘试区引黄补源条件下土壤盐分及地下水动态分析

商丘试验区属引黄补源灌溉与井灌相结合的灌溉类型区,引黄灌溉对试区土壤及地下水环境影响分析表明:引黄补源环境效果较为显著,试区地下水位长期下降的趋势得到了遏制;浅层地下水质得到了改善;引黄补源致使土壤盐分下移对作物生长有利。

Analysis of Irrigation of Utilizing Yellow River to Soil and Groundwater Environment in Shangqiu Agricultural Experimental District

Shangqiu Agricultural Experimental District is a irrigation area of utilizing groundwater and yellow river together, especially, it represents the district of middle-low food output in south of Yellow river, east of Shaying river in Huang-Huai-Hai region. It is very important to develop irrigation with Yellow river, it can keep groundwater level from dropping fast, raise food output, boost irrigation assure standard, and improve situation of water shortage in agriculture and industry of this area. The results showed that the irrigation utilizing yellow river has a obvious effect on groundwater level、groundwater quality and the movement of salinity in soil.
