以降水资源环境容量为基础控制林分密度,试验了不同集水技术对林地土壤水环境的改善作用,对林木生长的影响及集水技术的适用性.10年试验研究和大面积示范结果表明,在年降水量410mm左右地区造林,林地坡面经过不同的防渗处理,当每株树具有8m~2的集水面时,可使2m~2的植树带内收集到570～1270mm降水,造林成活率最高达到98%,林木生长量可提高40%～80%.
Based on the environmental capacity of precipitation resources, the stand density was controlled, and the effects of different water harvesting technologies on the improvement of forest soil water environment, the effects on forest growth and the applicability of water harvesting techniques were tested. The results of 10 years of pilot study and large-scale demonstration , Afforestation takes place in the area of about 410mm of annual precipitation, and the slopes of the woodlands are treated with different seepage control measures. When each tree has a catchment surface of 8m ~ 2, rainfalls of 570 ~ 1270mm can be collected in 2m ~ 2 trees, The highest survival rate of 98%, tree growth can be increased 40% to 80%.
