摘要:
宁夏南部山区是雨养农业区，也是半干旱退化山区，提高降水资源的利用率，是该地区生态环境建设的必然途径，通过分析研究点的雨水资源量，当地缺水的最大问题是降雨的时空分布问题造成了大量的雨水资源流失。坡地改造拦蓄径流就地利用和径流资源的拦蓄储备是解决缺水问题的两种途径。分析了坡地径流资源的潜力，并对坡地改造后不同工程措施降雨再分配情况进行对比研究，土壤平均体积含水量88542整地>鱼鳞坑整地>自然坡面，88542工程整地比鱼鳞坑工程整地高12.1%，比无工程整地措施高20.8%，可以有效提高造林成活率。
Abstract:
The mountain area in the south of Ningxia is an agricultural region and semi-arid degraded mountain area mainly relying on rainfall.The effective way of constructing ecological environment is to improve the utilization ratio of the rainfall source in the region by analyzing the rainfall source in the research place.The greatest problem that the area is in the absence of water is the time and space distribution of the rainfall,causing loss of rainfall source.The two way of solving the problem of water shortage are retaining runoff on the spot and retaining store of the runoff source in the hillside fields.Analyzing the potential of the runoff source in the hillside fields and comparing with the study on different rainfall re-distribution condition of engineering measure,it is concluded that water content of the average volume of soil,88542 soil preparationscale pits soil preparationnatural hillside surface,the water content of 88542 engineering soil preparation is 12.1% higher than scale pits engineering soil preparation and 20.8% higher than without engineering soil preparation measure.which can efficiently improve the forest live ratio.
