- 摘要:
- 目前，我国对适用于各地区大比例尺土壤侵蚀分级指标的研究较少，现行的土壤侵蚀强度分级标准，在野外实际应用中困难，对指导土地合理利用意义不大。根据多年来在辽宁省西部低山丘陵区的实地调查研究，抓住成土母质这一主导因素，根据不同成土母质土地的土壤质量分异规律、土壤侵蚀特点以及土壤遭受侵蚀后对土壤生产力水平、土地利用管理的影响不同等实际情况，选取不同的分级方法和分级标准，确立了适合辽宁西部低山丘陵区大比例尺土壤资源调查的土壤侵蚀程度分级指标体系。该分级指标体系具有针对性强、分级指标界限明确、可操作性强、对土地利用管理指导意义大等优点。
- Abstract:
- Up to now the research in the differentiation criterion of soil erosion suited for large-scale soil investigation was seldom carried out in China.The current differentiation criterion of soil erosion degree was difficultly used in practice and could not efficiently guide land use.Based on the field investigation results, three types of soil parent materials, which were the dominant factors of causing variation of soil quality and soil erosion characteristics in low mountain and hill area of western part of Liaoning Province, were classified.A differentiation criterion system of soil erosion suited for large-scale soil investigation in the area was established, according to the different types of soil parent materials.The differentiation criterion system of soil erosion established has many advantages.It incarnated fully the characteristics of soil resources in the area and had specific boundaries of differentiation.So it could be easily used in the field for large-scale soil investigation and could guide land use efficiently.
