Study on Spatial Distribution of Soil Nutrients in Sejila Mountain
In order to analyze the spatial characteristics of forest soil nutrients in Sejila mountain, based on field investigation and laboratory sample measurement,spatial distribution of forest soil nutrients was analyzed with GIS spatial interpolation methods.The results showed that, the soil of Sejila mountain was acidic,the organic matter and total nitrogen content of soil were higher than the national average,soil organic matter and available phosphorus content rised with increasing altitude,available potassium decreases with increasing altitude,total nitrogen content was higher in the middle of the mountain.The soil nutrient indicators in east and west slope were significantly different,and there were some variation regularities as altitude rised.
