摘要
在遥感和地理信息技术的支持下,应用SCS水文模型,研究了鲁山县1992年和2006年间土地利用变化及其对地表径流深度的影响。结果表明:土地利用变化表现在交通用地、工矿及居民点、耕地面积增加,林地、水域面积减少。随着人类活动的加剧,土地利用结构的变化,尤其是城镇工矿用地增加和林草地减少使径流量趋于增大。在假设降雨量一致的情形下,地表径流深增加了0.364 mm。
With the support of RS and GIS,the impact of land use change on surface runoff in Lushan county was analyzed by means of the SCS hydrological model in 1992 and 2006. The result showed that the areas of cultivated land and urban-land increased, while water-body and forest land decreased during the past 15 years. Along with the increased activities of human beings and the structure change of land use, especially the increase of city/factory land and the decrease of woodland,the surface runoff increased by 0. 364mm from 1992 to 2006 at the condition of same precipitation.
