| Taking the Nianzhuanggou watershed as a research field,the soil moisture characteristics of terraced field and dammed land were analyzed.The fact showed that the vertical distribution of the soil moisture in terraced field and dammed land has the similar characteristics.The vertical moisture variation of terraced field and dammed land could be divided into 4 layers: soil moisture drastic change layer,soil moisture activity layer,soil moisture low activity layer and soil moisture relatively stable layer.The soil moisture of dammed land was higher than that of terraced field,also the different crop types could causes soil moisture change and the change is extremely remarkable between different crop types. |
