Proceeding with the analysis of water resource peculiarity of jilin province, the authors bring forward that effective gathering and using of rainwater can supplement the gross amount of rainwater in valley, probe into rainwater resources use in jilin province : first is to make rainwater resources use plan in valley program, secondly is to construct gully dam system according to water and soil conservation project, to strengthen sloping field collection rain ' s project and forest - grass construction, to increase storage space, thirdly is to fully utilize field project and water conservancy project to gather rain water, intercept rainfall on the spot so as to restore water environment
摘要從吉林省水資源特點分析入手，提出了雨水資源的有效集蓄利用是補充流域水資源總量不足的重要因素，探討了在吉林省雨水資源主要利用途徑是首先在小流域規劃中作好雨水資源利用規劃；其次是建設以水土保持治溝骨幹工程為主的溝道壩系，強化坡面集雨工程和林草植被建設，增大貯水空間；第三是充分利用田間工程和水利工程集雨蓄水，使降雨就地就近被攔蓄，最終使水環境得以修復。 -
On the basis of analyzing factor ( soil particle composition, soil bulk density, water stable aggregate content, antecedent soil moisture, slope gradient, rain intensity, accumulation depth and soil crust, soil and water conservation tillage measures ) affecting soil infiltration rates, several relation models was obtained ; analyzed in detail different soil and water conservation tillage measures intensifying infiltration rates, while there have the same rainfall condition, the increasing infiltration rates of contour tillage and artificial digging and artificial hoeing in gully areas of loess plateau are 67 % and 41 % and 29 % ; the increasing infiltration rates in hilly areas of loess plateau is 45 % and 22 % and 14 %
在相同的降雨條件下，黃土高原溝壑區等高耕作與直線坡相比，可提高入滲67 ，人工掏挖可提高入滲41 ，人工鋤耕可提高入滲29 ；黃土丘陵溝壑區等高耕作可提高入滲45 ，人工掏挖可提高入滲22 ，人工鋤耕可提高入滲14 。並根據黃土高原超滲產流的概念和水量平衡方程，建立了不同水土保持耕作措施強化入滲速率模型。
