通过卫星普查和典型调查研究结果表明,辽宁东部山区土壤侵蚀面积已占该区总面积的35.2%,侵蚀模数升级。主要因素是由于开发失控而导致陡坡开荒、超坡栽参、蚕场退化和矿产开采等所引起的土壤侵蚀。
The results of satellite surveys and typical surveys show that the area of soil erosion in eastern Liaoning has accounted for 35.2% of the total area and the erosion modulus has been upgraded. The main factor is soil erosion caused by uncontrollable development of steep slopes, over slope planted, degraded silkworms and mineral exploration.
