摘要

以福建省东南沿海水蚀区的晋江流域 (泉州市)为实验区

(1)利用大量的水土保持实验数据和USLE原型结构(即A=fRKSLCP)

建立了适合该流域水蚀区的土壤侵蚀遥感测报模型;(2)在中国南方红壤地区率先建立了县(市)级土壤侵蚀定量遥感测报系统

实现了土壤侵蚀定量、实时、快速测报

并在全流域 1.10× 10

土地上推广应用;(3)建立了以像元(30m×30m)为基础的空间数据库系统及其可更新的 GIS系统

同时

还建立了防治类型预报模型

能够根据当地土壤侵蚀防治需要与经济承受能力提出了防治类型预报建议。根据对流域中下游的南安市 (面积2042.72km

)实现动态测报

与水文法、径流小区法、实地调查法和档案法比较

其一致性达80%以上。

Abstract

Jinjiang watershed

located in the water eroded area of southeast coastal area of Fujian province

was used as an experiment zone. A remote sensing prediction model on the soil erosion suitable for watershed erosion area was established by using a great deal of data collected from soil and water conservation experiments

and prototype structure of USLE(A=fRKSLCP). A quantitative soil erosion remote sensing prediction system at county(city) level in red soil area in southern China was also established innovatively

realizing the quantitative

real time

and quick predicting on soil erosion. This prediction system was applied in an area of 11 000 km2

and a spatial database system based pixels of 30m×30m and its renewable GIS system were established. According to the dynamic prediction made in 1988

1995

and 1996 in Nan'an city which is located in middle and down stream of the watershed. the result consistency comparing with the hydrologic method

runoff plot method

on spot investigation method

and file method reached more than 80%.
