长江以南东部丘陵山区土壤可蚀性K值研究
- Title:
- Soil Erodiable K in East Hillyfields of the Southern Yangtze River
- 摘要:
- 以土壤亚类为基础，从土种入手，依据第二次土壤普查资料建立了我国东部丘陵区各土种的理化性质数据库。应用土壤可蚀性方法，计算出各土种的土壤可蚀性K值，用面积进行加权平均，经分类分级后，连续到相应的土壤图上，得到我国东部丘陵区土壤可蚀性K值图及其分布规律。
- Abstract:
- Based on the subsoil species and the second soil survey information, the author established the national data pool of various subsoil types for the east hillyfields in the southem of Yangtze river. Using the method of soil erodiable K to calculate K values of various subsoil types,through dividiation,and then linking the values to the relative soil maps, the soil erodiable K value maps and their distributive regulares have been given out here.
