| 摘 要： | 以湖南省洞口县月溪国有林场生态公益林为研究对象,对其成熟林优材更替前后水土保持效益进行了研究.结果表明:1#更替模式(新造杉木纯林)和2#更替模式(新造杉木+樟树混交林)的地表径流量、泥沙流失量都比3#更替模式(CK,未砍伐杉木过熟林)大2～3倍；前者实施了挖穴造林,破坏了地表土壤结构,但水土流失系数没有超出允许浸蚀量...

| Abstract: | Study on benefit analysis of soil and water conservation about excellent material change of ecological forest was taking Yuexi State-owned Forest Farms in Dongkou County as study area.The results showed that the surface runoff,soil loss amount of 1#(the new afforestation pure forest of Chinese fir),2#(the new afforestation mixed forest of Chinese fir and Cinnamomum camphora)runoff plot are 2~3 times lager than 3# runoff plot(CK).The former implementation of digging planting and destruction of surface soil s... |
