应用水土流失定量遥感方法监测山东全省山丘区的研究

本文简要介绍了水土流失定量遥感方法的组成和基本原理，重点叙述了它在山东全省山丘区的应用作业和应用结果，并讨论了它的准确性，实用性和应用前景等。该法的监测模型可与美国近年刊出的ＲＵＳＬＥ相媲美，且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

STUDY ON QUANTITATIVE REMOTE SENSING METHOD FOR SOIL EROSION LOSSES AND ITS APPLICATION IN SHANDONG PROVINCE, CHINA

In this paper, a quantatative remote sensing method for soil erosin losses is briefly introduced, and its operation and application in the mountain and hilly areas of Shandong Province, China are described.Although the model form of this method for monitoring soil erosion losses is the same as that of the (American) RUSLE, the formula and algorithms for model factors are generated from the loss data observed in China.Therefore, the method is more applicable to loss regions in our country and is suitable for personal computers to process the data of GIS and remote sensing.It is a more accurate and practical method compared with the conventional survey method and the qualitative remote sensing method.The results of its application include the total loss of region, the area of different grades of soil loss, the soil erosion map, and the forecast map of soil conservation.The total losses monitored by the quantitative remote sensing method are conformable to the deposition values observed and calculated by hydrometric stations in the 9 reservoir valleys with an average accuracy of 82.96%, showing the accuracy of the monitoring results obtained by this method in Shandong Province (see Table 2).
