Spatial Variance Analysis of Soil Nutrients in Pinus tabulaeformis in Fuxin Region

Tian Mingfang;State-owned Forestry Science and Technology Demonstration Forest Farm,Fuxin Mongolian Autonomous County,Liaoning Province;  
In order to clarify the spatial differences of soil nutrients in Pinus tabulaeformis forest in Fuxin area,western Liaoning Province,taking 35-year-old pure forest of Pinus tabulaeformis as objects,the soil samples at different slope position and slope were collected,soil nutrient indicators were measured and analyzed.Result shows that from the slope position,all the tested nutrients below the slope have the highest contents,except for available K,the order of content for organic C,total N,available N available P is below the slope slopeabove the slope.From the aspect of slope,the content of nutrients in all the detected nutrients are the highest in the shady slope and the lowest in the semi-shady slope,N and available P content in the order of shady slopesemi-shady slopesunny slope semi-sunny slope.The order of available N available K content is shady slope semi-shady slopesemi-sunny slope sunny slope.f
