求翻译：结果表明：草堂溪流域从1990—2007年轻度侵蚀面积增加最多；中度侵蚀面积减少最多。中度侵蚀从1990年到2007年土壤侵蚀综合指数最大。人为影响坡耕地开垦是土壤侵蚀动态变化的最主要原因。是什么意思？

The results showed that: Cottage Creek watershed from 1990-2007 degree of erosion area increased up to the young; moderate erosion area decreased most. Moderate erosion from 1990 to 2007, the largest index of soil erosion. Human impact on soil erosion in sloping land reclamation is the main reason f

Results indicate that: sodo river basin erosion from 1990 - 2007 young degrees; Moderate erosion area increase up maximum reduction in the area. Moderate erosion from 1990 to 2007 the largest soil erosion Composite Index. Anthropogenic influences on farmland cultivation slope is the main cause of so

The result indicated that,The thatched house brook basin increases many from 1990-2007 year mild corroded area; The moderate corroded area reduces most much.The moderate corrosion the soil erosion composite index was biggest from 1990 to 2007.The artificial influence slope farming opens up wasteland

The results show that the cottage Creek Watershed from the mild erosion in 1990-2007 increase in the size up to; up to moderate erosion area declined. Soil erosion index maximum erosion from 1990 to 2007. Human impact dynamic changes of soil erosion in sloping land is the major reason why.

The results showed that: Cottage Creek watershed from 1990-2007 degree of erosion area increased up to the young; moderate erosion area decreased most. Moderate erosion from 1990 to 2007, the largest index of soil erosion. Human impact on soil erosion in sloping land reclamation is the main reason f
