缙云山两种植被类型对坡面产流的影响

Research on slop runoff process in two vegetaion types in Jinyun Mountain in Chongqing City.

该文以重庆市缙云山的两个不同植被类型常绿阔叶林 (四川大头茶 )和楠竹林小区为研究对象 ,对小区中典型降雨后的地表径流、地下径流的实测资料进行对比分析 .结果发现在相同降雨条件下 ,楠竹林的地表径流量与地下径流量明显要比常绿阔叶林的大 ,楠竹林地表径流和地下径流出现的时间也比常绿阔叶林早 ;两种植被的地表径流与地下径流过程具有一定的相似性 ,地下径流量都比地表径流量大 .

The paper studies on two different vegetation type areas in Jingyun Mountain in Chongqing City,which are broadleaved forests(Gordinya svchuanensvs)and bamboo (Phyllostachys edulis)forests.By contrasting the surface runoff and underground runoff in these two areas, the results showed that,with the same precipitation,the gross amount of runoff in bamboo forests was larger than that in broadleaved forests and the runoff in bamboo forests appeared before that in broadleaved forests.The amount of underground runoff was larger than that of surface runoff in the two areas,the process of surface runoff was in accordance with that of underground runoff.
