湖北武当山区土壤侵蚀景观成因机理研究

Study the Mechanism on Soil Erosion Landscape in Wudangshan District of Hubei Province

尽管"长治工程"在丹江口市有较大的投入,从多时相的遥感影像上发现,武当山区土壤侵蚀景观结构为斑散布型,斑的分布具有明显的空间地带性,斑与基间进行了强烈的土壤流交换,局部地区水土流失仍在加强。人类活动与水土流失间的关系复杂,具体表现为缓变性与突变性、可避防性。人类活动是影响武当山区水土流失的主要因子。

Though a great deal of engineering has been dived into Danjiangkou city in the course of 'Project for Regulating the Yangtse River', the following facts based on multitime remote sensing image were discovered. The framework of soil erosion landscape in Wudangshan district is the patch scattering, the patch is only scattering in some special spatial zone, the soil current has been exchanged between the patch with matrix, a specific part of the Wudangshan district soil erosion intensified. The relation of human action and soil erosion is complex,the complexity of representation is slowly and abruptly, and avoidance. The human action is the primary factor to bring on soil erosion.
