| 摘 要： | 以Ｗｉｎｄｏｗｓ９５（９８）为工作平台，以ＡＲＣ／ＩＮＦＯ地理信息系统（ＧＩＳ）及Ｃ语言为支撑软件，开发了包括植被、坡度、土地利用、降雨等因子的水土流失定量分析模型和水土流失信息系统，以卫星遥感ＴＭ数字光盘为主要信息源，对浙江省水土流失状况进行普查研究表明，浙江省水土流失面积较１９８７年普查结果有所减少，但中度以上流失面积明显增加，水土流失总面积中，疏林地流失面积占８６４％，坡耕地流失面积占１１％。

| Abstract: | A quantitative analysis model
and information system of soil and water loss, in which vegetation, slope, land use, rainfall and
other factors are taken into account, are developed under Windows95(98) by using ARC/INFO
GIS and C computer language as supporting software. Study and investigation of soil and water
loss in Zhejiang province has been carried out by taking satellite remote sensed TM digital CD
as major information source, and the results demonstrate that the area of soil and water loss in
the province is now less than that in 1987,but the area of over middle degree in soil and water
loss increases evidently. Among all the area of soil and water loss, 86 . 4% are located in spare
tree forest and 11% in slope cultivated land. |
