【摘要】 对木荷林地、杉木林地和柑桔林地的“土壤水库”库容大小与分布特性进行比较分析,结果表明:木荷棘地土壤水库的总库容和最大有效库容分别为503.94、389.65 mm,土壤水库的防洪效能最强;杉木林地和柑桔林地最大有效库容分别为382.02、341.38 mm,杉木林地防洪效能高于柑桔林地;对照地(裸露地)贮存水分能力最低,防洪减灾的效能最差。更多还原

【Abstract】 Soil water reservoir was defined as a space that reserve and transport the soil water in the soil, and total pore space of the soil as maximum available volume of the reservoir. The volume of pore space and the water transportation capability of soil are two of the important reservoir characteristics. The storage capacity and distribution characteristics of Schima superba (SC), Cunninghamia lanceolata (CL) and Citrus sp. (CS) were studied. The result showed that the total storage volume and maximum effective storage of water reservoir in SC were 503.94 mm,389.65 mm.respectivrly, and its capacity of flood control is the best of there plantation. The maximum effective storage of CL and CS were 382.02 mm,341.38 mm, respectively. The capacity of storage in control is the lowest , and the efficiency of flood control is the last one in the sequence. The results also show that the soil water reservoir theory is available used to assess the flooding control function of soil. Capabilities of the soil water reservoir, including soil water reserve and water transport, are most important when we study on soil water reservoir to control flooding. How to increase soil in filtration? It is a key to improve efficiency of the reservoir on control flooding.更多还原
