摘要
利用ＧＩＳ、ＲＳ和数量化理论，对厦门市水土流失进行快速调查。结果表明：厦门市水土流失总面积为１７０．６５ｋｍ２，占土地总面积１０．９１％，比１９８４年下降了９．９９％，其中强度和中度的降幅分别为５．９４％和４．３３％。通过野外实地验证，准确率达８２．５％。
With the application of GIS,RS and quantification theory, fast survey of soil and water loss in Xiamen was accomplished. The results showed:the total area of soil and water loss in Xiamen was 170.65 km 2 ,which occupied 10.91% of the total area of land in Xiamen.Compared with 1984,the area decreased by 9.99% and the decreasing range of serious and medium erosion degree was 5.94% and 4.33%, respectively.Through on the spot test,the degree of accuracy reached 82.5%.
