Abstract:
Using full surface grid sampling method,the distribution characteristics of soil nutrient in Shahe small watershed of Guizhou Weining Caohai was carried out.The results showed that organic matter，available N，available P and available K were at a high level；contrary，total N，total P and total K were very poor in the studied area.Different land use type had different soil nutrition content.The variation trend of organic matter content was：artificial grassland>natural shrubland>sloping farmland>planted woodland>wild grassland；the variation trend of available N was：artificial grassland>natural shrubland>sloping farmland>wild grassland>planted woodland；the variation trend of available P was almost the same as the total P：sloping farmland>artificial grassland>wild grassland>natural shrubland>planted woodland；the variation trend of available K was：artificial grassland>sloping farmland>natural shrubland>wild grassland>planted woodland.The research also showed that total N and total K didn’t have much more relationship with land use type.In generally，soil nutrient content was the highest in artificial grassland and the lowest in planted woodland，the variability coefficients showed that all of the nutrients belonged to middle intensity variation.
