花岗岩坡地土壤侵蚀强度分级参考指标探讨
- Title:
- The Discussion on the Reference Index of Soil Erosion Intensity Class in Granite Slope
- 摘要:
- 根据实测资料建立了花岗岩坡地土壤侵蚀强度模型，并对土壤侵蚀强度分级标准进行了讨论，认为2OOt/km2为土壤允许侵蚀量较合适。在此基础上建立了土壤侵蚀强度分级参考指标系统。该指标是以侵蚀量为基础的，且各指标在野外获取容易，所以该土壤侵蚀强度分级参考指标可以在条件相似的广大南方花岗岩地区推广试用。
- Abstract:
- Based on the measured data obtained from Anxi,Changting and Nanan experimental stations, the model of soil erosion intensity has been established. The criterria of soil erosion intensity class were discussed in the paper and it is suggested that 200t/km2. a can be adopted as a permissible soil erosion in granite area on the basis of the rate of soil forming. The reference index system of soil erosion intensity class has been set up in the light of the established model of soil erosion intensity. The proposed reference indexes of the classification could be adopted for soil erosion survey in granite areas of southern China because the above factors indexes could be gained easily in field.
