Consideration of Offsite Impacts in Targeting Soil Conservation Programs
研究了在制定土壤保护计划时，应同时考虑水土流失的场外影响（如水质改善）和场内影响，发现仅考虑场内影响会导致目标区域选择效率低下。
The offsite impacts of soil erosion should be considered in targeting regions for soil conservation programs. Regions where a reduction in erosion on agricultural land would improve water quality were identified, and compared to regions targeted using onsite criteria. Differences in the regions identified indicate that failure to consider both onsite and offsite impacts may result in inefficient targeting.
