| Abstract: |
| A study was carried out on the characteristics of soil nutrients under three land use types of farmland, forest and grassland in Liudaogou watershed by using traditional statistics combined with geo-statistics. The result showed that soil organic matter content was farmland＞forest＞grassland, soil total N content was farm land＞forest＞grassland, soil total K was grassland＞forest＞farmland, available nitrogen content was farmland＞forest＞grassland, available P was farmland forest＞grassland, available potassium was forest＞farmland＞grassland; soil C/N was forest＞grassland＞farmland; It showed a linear relationship between organic matter content and total nitrogen content, and reached a significant level (P<0.01). Different land use types had important influences on soil nutrient content. |
