摘要

以福建省长汀县为研究对象

基于遥感技术手段

运用USLE方程计算了区域水土流失量。在此基础上进行相关的处理获得各乡镇的水土流失率。结合各乡镇的单位面积绿量

通过相关分析与建立模型定量描述了两变量之间关系。结果表明

单位面积绿量与水土流失率呈明显的负相关

各模型的R

均在0.5以上。研究结果可为区域的森林合理经营和水土保持提供决策支持。

Abstract

Taking Changting County of Fujian Province as a study area

based on the geomatics technology

the amount of soil and water loss was calculated by using USLE(universal soil loss equation). Then combined with the green biomass of every town

the model of quantitative description of the relationship between these two factors was established. The result showed that the green biomass of unit area was negative correlated to soil and water loss obviously

the R2 of each model was more than 0.5. The research conclusion can provide support for decision-making of regional forest management and soil and water conservation.
