该文依据多种集水技术条件下的降雨径流观测资料和林地不同空间位置上定期土壤水分观测资料，分析了在半干旱黄土地区集水造林技术与土壤水环境的关系，林木对水分的利用状况及林地水量平衡。结果表明：集水技术不仅改善了土壤水环境，而且提高了林木对降水的利用率。
Based on the data of rainfall and runoff under a variety of water harvesting techniques and the regular soil moisture data at different spatial locations of forest land, the paper analyzes the relationship between water harvesting afforestation technology and soil water environment in semi-arid loess area, Condition and water balance in woodland. The results show that: Catchment technology not only improves soil water environment, but also improves the forest utilization of precipitation.
