小流域水资源持续高效利用研究探讨

采用"小流域水资源动态监测及开发利用研究"课题中的小流域水资源动态模型,计算出小流域地上、地下水资源拥有量的基础上,结合流域综合治理,在宁安市红城小流域中进行定点观测试验,经3年的研究,山地果树保水、保土率分别达到78%和89%,与传统沟灌相比,微喷灌技术节水75.9%,节电40%,节省土地12%,增产2～4倍,一级果品率可达70%以上,水果、蔬菜单位面积产量增加达30064kg/hm²和65553kg/hm²,在小流域水资源持续高效利用上进行了有益尝试.

Discussion on Continuously High-efficiently Use of Water Resource in Small Watershed

Adopting the dynamic model of water resources in a small watershed of "study about monitoring,development and utilization of water resource in a small watershed" to calculate out small watershed on the ground,groundwater resources amount,combined basin comprehensive control,the authors conducted a fixed position observing test among Hongcheng basin of Ningan city.Through three years’ research,protecting water and soil rate up to 78% and 89% mountain region fruit tree,respectively,compared with traditional furrow irrigation,little sprinkling irrigation technology economize on water 75.9%,economize on electricity 40%,save 12% land,increase production 2～4 times,first class fruit rate can reach more than 70%,fruit and vegetable,increase yield up to 30 064 kg/hm² and 65 553 kg/hm²,getting good results on continuously high efficient use of water resource in small watershed.
