摘　　要：黄土高塬沟壑区,具有十年九旱的气候特征。为了实现雨水资源利用的最大化,选用几种常见的具有防渗作用的新材料对集水造林试验的集水区进行处理,并优选出了合适的处理方法。其中包括喷甲基硅酸钠,喷RG-100C1型高分子乳液,喷3F克渗王防水剂,掺3F克渗王防水剂,撒水泥并喷水等5种的集水效果的试验研究。通过对比研究,结果认为喷甲基硅酸钠在集水效果和资金投入上占有优势,具有推广价值。The loess gully area is characterized by the climate of 9 drought years out of 10. In order to realize the maximum utilization of rainwater resources, the catchment used for afforestation experiment was treated with several kinds of common and new materials with the function of seepage prevention and suitable treatment methods were selected. They include spraying methyl sodium silicate, spraying RG-100C1 macromole emulsion, spraying 3F gram waterproofing agent, mixing 3F gram waterproofing agent, spreading cement, and spraying water. Through the analyses of various research methods, spraying methyl sodium silicate is found to be the best in collecting water and thus, has a greater value in extension.
