| 摘 要： | 苏南丘陵区存在多种利用当地土地资源方式，诸多利用方式也改变了土壤的性能，一般是人类干预下的耕地的土壤侵蚀及养分流失高于处在自然半自然状态下的非耕地。为了定量了解由土壤侵蚀引起的养分流失，首先应掌握土壤侵蚀的强度，^137Cs示踪法可以对此提供帮助。使用此法需解决2个问题：确定研究区域的^137Cs背景值与建立估算土壤侵蚀的模型，我们在这方面做了合理的尝试。以此为基础，估算了各种利用方式下土壤养分流失量；为了与黄土和红壤区土壤侵蚀的危害相比较，提出了等值侵蚀模数的概念，以便揭示苏南地区土壤侵蚀的潜在危害性。通过研究初步确认耕地尤其是水田可能是太湖水体营养元素的主要农业来源。

| Abstract: | Yushenfu coal mine has very rich coal resource and it is one of the key fuel energy and heavy chemical industry base in China.It locats in loess-hilly area and Maowususandlot,northeast of Erduos basin,where have badly natural conditions and fragile environment system.Soil and water loss in natural environment is one of the main environmental geology problems in this area.Soil and water loss will become more seriously problem with large scale development of coal resources.According to three terms(1987,1992,1999)explaining results of TM remote sensing image,and under the support of data-base of GIS,the influence factors of soil and water loss and its trends are estimated by using arrangement analysis.A primarily forecasting and evaluating is made on coal mine exploitation that may affect natural environment based on the results of our survey.This would provide basic information for environmental protection. |
