摘要
在GIS支持下研究了流域内不同土地利用条件下土壤侵蚀规律,研究结果表明:辽河中下游流域在1995～2000年短短5年期间,随着人口增长和对土地利用开发强度的增大,加剧了土壤侵蚀速度和侵蚀强度,进而使土壤侵蚀模数和土壤侵蚀量增加。
This paper studied the laws of soil erosion on different land use conditions in one drainage basin based on the support of GIS. Following conclusion could be drawn: during the short time of 1995~2000, with people increasing and development intensity of land use, the rate and intensity of soil erosion were accelerated. Soil erosion modulus and amount of soil erosion would be increased in the middle and lower reaches of Liaohe river valley.
