| 摘 要： | 该文通过对广东信宜县森林生态系统的林冠截留缓冲作用、枯枝落叶层的持水保土作用、林下土壤的渗透性能等几个方面的分析研究，论证了信宜县森林生态系统在保持水土、涵养水源、调节径流等方面所起的重要作用。同时，通过对各类型森林生态系统的枯枝落叶最大持水量、林下土壤层的非毛管孔隙度大小及林下土壤层渗透速度大小等几个指标对比，得出信宜县各类型森林生态系统在涵养水源方面的效能高低顺序是：常绿阔叶林优于针阔混交林，而针阔混交林又优于松、杉林的结论。

| Abstract: | By analyzing forest canopy's rain-Keeping and Cushioning effect,forest litter's water-holding and soil-protecting effect,soil's penetration ability,forest plant-soil system's important roles in water-holding and soild-protecting,water supply-conservating and runoffadjusting are expounded and proved;By comparing the index data of severl forests' efficacy in the maximum amount of forest litter's water-holding,Soil's non-capillary porosity and soild's penetration rate,the superior sequence in conservation of water supplying is evergreen broadleaved forest,mixed forest and needle leaved forest. |
