用很多小区尺度的研究结果外推到流域尺度都过高地估计了流域尺度的土壤流失量。印度尼西亚的许多地区在小区尺度上研究了土地管理制度对水土流失的作用 ,但在流域尺度上研究的很少。我们于 1 999年在爪哇中部开始研究 ,目的是比较 3个不同尺度、不同土地利用方式小流域的土壤
Extrapolation of many of the cell-scale findings to the basin scale has overestimated soil-scale soil erosion. Many parts of Indonesia studied the effect of land management system on soil erosion at the district scale, but few studies have done on the basin scale. We started our study in central Java in 1999 with the aim of comparing the soil of three small watersheds of different scales and different land-use types
