| 摘 要： | 通过山西省吉县森林生态系统国家野外科学观测研究站蔡家川流域的实验观测，采取对比分析的方法，对不同土地利用类型小流域场降雨径流产沙过程进行研究。结果表明：在降雨量分别为8．6和13．6mm的场降雨过程中，半农半牧小流域洪峰与沙峰基本同步，次生林小流域沙峰明显滞后于洪峰；农地小流域场降雨地表径流系数、产沙模数最高，分别为2．40％、6．40％和6．71t／km^2、73．69t／km^2；次生林小流域场降雨地表径流系数、产沙模数最低，分别为0．13％、0．75％和0．02t／km^2、6．95t／km^2。

| Abstract: | As an important parts of watershed hydrology research,study on runoff and sediment process is the fundamental content of watershed hydrology modeling.The watershed in West of Shanxi Province which is a national forestry ecology research station was analyzed by experiments,runoff and sediment process from different types of land use was researched by contrastive analyzing.The results show that during the representative rainfall events(rainfall amounts: 8.6 mm and 13.6 mm),suspended sediment concentration var... |
