Based on the RS data,the watershed inventory data derived in 2001 and 2003,and the field data,including physiognomy,vegetation,and rainfall,RUSLE is combined with GIS to estimate the soil loss by erosion.
借用地理信息系统(GIS)和遥感(ERDAS)技术,以修正的通用水土流失方程(RUSLE)为核心,根据吉溪流域2001年和2003年的遥感影像解译数据和统计资料得到地貌、降雨量、植被等资料,量化流域土壤侵蚀评价因子,对吉溪流域土壤侵蚀进行了定量化分析。

结果显示:泥河沟流域土地生产力的变化差异很大,总体上以林地最高,果园和草地次之,农地最低;整个流域土地生产力呈现出以村庄为中心辐射状递减(农地)和斑状交错(果园)分布特征,土地生产力随着土壤侵蚀强度增大呈现指数规律减小。
Water erosion creates negative impacts on agricultural production,infrastructure,and water quality across the world.
在全世界范围内土壤侵蚀对农业生产和水质量都有着负面影响,因此区域尺度的土壤侵蚀评估非常重要,但是它往往会受可收集到观测数据的数量和质量的限制。
Based on field investigation at the Shangyang Soil Conservation and Reforestation Station in Huizhou, Guangdong Province, China, vegetation development, the vegetation succession process, and soil erosion variation are studied in this paper.
通过对广东惠州市惠阳区上杨试验站等南亚热带典型水土流失地区的研究发现:自然封育状态下,水土流失地区植被恢复和演替缓慢,25a后植被覆盖度只有35%,且主要以阳生性耐贫瘠的灌木及草本为主,土壤侵蚀仍然比较严重。
