为了加快我省水土保持工作,保护土壤,合理利用土地资源,在开展土壤普查和资源调查工作的同时,也应同时进行土壤侵蚀的调查研究,完成公社一级的侵蚀程度图和水土保持规划、县一级的土壤侵蚀分区和水土保持区划,为开展群众性的水土保持工作打下基础。根据我们对忠县的土壤侵蚀调查,通过几十个典型样方资料的分析,并结合其他试验研究,初步提出我省盆地丘陵区,耕地土壤侵蚀程度的分级指标,供土壤侵蚀调查参考。
In order to speed up the work of soil and water conservation in our province, protect the soil and make rational use of the land resources, we should carry out the investigation and study of soil erosion at the same time as carrying out the soil census and the resource investigation work, complete the maps of the level of soil erosion, The division of soil erosion and the division of soil and water conservation at the county level lay the foundation for carrying out mass water and soil conservation work. According to our investigation of soil erosion in Zhongxian County, through the analysis of dozens of typical sample plots, combined with other experimental studies, we initially put forward the grading index of the degree of soil erosion in hilly areas and cultivated land in our province for the reference of soil erosion investigation.
