Abstract

Abstract: Employing GIS, grid-maps and order correlation analysis, this paper studied the correlation between land use- and soil erosion intensity on the Loess Plateau of Northern Shaanxi Province. The results showed that in this region, soil erosion intensity was highly related to land use intensity, indicating that land use intensity was the main driving force of soil erosion. Regression analysis suggested that the effect of land use intensity on soil erosion intensity was determined by the integration of natural factors, e.g., in flat and humid areas, human activity had a less effect on soil erosion intensity, and vice versa.

Key words: Wetland ecosystem, Indicators, Ecological engineering type
