摘要

摘要: 以重庆市南桐矿区为研究对象,运用遥感和GIS技术获取对水土流失影响较大的植被覆盖度、地形坡度、土地利用类型等信息并进行空间叠加分析,计算了水土流失类型及面积。研究结果表明,南桐矿区水土流失面积262.91km2,侵蚀模数2281t/(km2?a),水土流失强度以轻度和中度为主,其中轻度流失132.37km2,中度流失108.95km2。根据区域地貌类型以及水土流失特征,将研究区水土流失划分为盆边低山丘陵中强度流失区、北部坪状低山中轻度流失区和盆边中山轻度流失区三个类型区,盆边低山丘陵中强度流失区以中度流失为主;北部坪状低山中轻度流失区以轻度流失为主;盆边中山轻度流失区虽然以轻度流失为主,但微度流失也占有相当部分的比重。

Abstract: Important factors that influencing soil erosion, vegetation coverage and land slope as well as land use types, are obtain by means of RS and GIS in the Nantong coal mining area. Soil erosion type and areas are calculated by space analysis of GIS. The results of the study show that soil erosion area is 262.91 km2 in the Nantong coal mining area. Soil erosion intensity is mainly slight and moderate. The average soil erosion reaches up to 2281 t/(km2? a). The slight soil erosion area is 132.37 km2 and moderate erosion area is 108.95 km2. Though the grade of soil erosion intensity is not high, the soil erosion area is large and thus the soil erosion is serious. According to the regional land types and characteristics of soil erosion, the investigated area is divided into three regions with different types. The eroded area in the mid-intensity erosion grade hill on the edge of the basin is large, and the main erosion type is mid-grade. The main erosion type is slight in the flat lower mountain mid-slight erosion region in the north. In middle mountains on the edge of the basin, the main erosion type is slight with large non-erosion area.
