| 摘 要： | 应用RS和GIS技术,依据水利部颁发标准(SL190-96),对辽宁省境内老哈河流域1990年和2000年的土壤侵蚀状况及其时空变化进行了研究.结果表明,10年中老哈河流域土壤侵蚀状况总体有所恶化,具体表现为中度侵蚀面积明显增加,而强度以上侵蚀面积有所减少;空间上,主要恶化区域集中于研究区中东部的大康家窝铺一带,而流域北部的老官地镇和烧锅营子乡土壤侵蚀状况则有所改善.土壤侵蚀强度变化的主要原因与该区土地利用类型变化直接相关.

| Abstract: | Based on the standards of classification and gradation of soil erosion issued by Ministry of Water Resource PRC,the soil erosion and its temporal-spatial evolution of the Laohahe river basin in the years of 1990 and 2000 were investigated with remote sensing(RS) and geographic information system(GIS) techniques.The results indicated that the soil erosion of the basin had been deteriorating as a whole,i.e.,the area of medium-intensity soil erosion were enlarged greatly,while the overeroded area gradually dec... |
