- Abstract:
-
Southwest karst area is the key area for soil erosion control in China. Nevertheless, scientific, objective, user-friendly and quick method for evaluation on the ecological effects of soil and water loss control in Southwest karst area is unavailable. Through a combination of data statistical analysis with experts’ experience, we established an index system for the ecological effects of soil and water conservation on different scales in karst area of southwest China, and proposed a quantitative model for the evaluation as well. The case study shows that:this method balancing scientificity and practicability can provide a quick quantitative evaluation for the ecological effects of soil and water loss control on the slope, in small watershed and region in southwest karst area, can also offer some references for the future monitoring and evaluation for the ecological effects of soil and water conservation in karst area of southwest China.
