湖北省丹江口市土壤侵蚀景观形成机理

Mechanism of Forming Soil Erosion Landscape on Danjiangkou City of Hubei Province

湖北省丹江口市境内有国家级丹江口多功能水库 ,对库区水土流失机理研究有较重要的理论和实际意义。将土壤侵蚀区位定义为土壤侵蚀发生区位、致灾因子及治理措施区位 ,其区位含义不同于前人的土壤侵蚀区位理论。丹江口市土壤侵蚀景观以武当山镇—浪河镇一线为界具明显的 2分性 :南部土壤侵蚀景观呈斑块状分布 ;北部土壤侵蚀景观多为定向排列的廊带状。这一景观结构的形成与公路断裂的现代构造运动、地壳物质组成的差异和人类活动的差异相关。

The multi function Danjiangkou reservoir with national stage is in churchyard of Danjiangkou city of Hubei province, Studying on mechanism of soil erosion to reservoir range has an important theoretic and practical meaning. The soil erosion location just as the follows: happening, factor leading disaster and curing means. This theory of location differs from previously theory. The soil erosion landscape of Danjiangkou city can be divided into two parts with the boundary of Wudang mountain Langhe town. The patch of landscape in the southern is scatter, the corridor of landscape in the northern is directional. The cause of two the landscape grillwork formation is correlation with the following factors, current tectonic activity of road fault zone, difference of material crust and activity of mankind.
