    摘要:

    本文介绍了水土流失定量遥感方法、应用实验和结果,并讨论了它的实质和应用前景等。该法的监测模型虽有与USLE和RUSLE相同的表达形式,但其因子算式算法系由我国实测资料所建,故有更合我国流失实际的应用效果,尤其它适用于遥感和GIS数据的微机处理。其应用结果不仅有比常规调查法和定性遥感法更准确实用的流失总量、各级面积的统计数据和流失现状图,而且还有流失治理规划的防治强度预报图。实验区的应用结果,得到当地水保部门的肯定和使用。

    Abstract:

    A quantitative method of remote sensing for soil erosion is described in this paper. Although form of the model for monitoring losses in the method is the same as the USLE and RUSLE, the formula and algorithms for model factors are generated from loss data observed in our country. Therefore, it is more applicable to loss regions in our country, and suits personal computer proccssing of the GIS and remote sensing data. The results of its application which include the total loss of region, the area of soil loss grades, the soil erosion map and the forecast map of soil conservation, are more accuracy and useful than those of existing methods for the conventional survey and qualitative remote sensing.
