Research on Evaluation of Soil Fertility Resource Space Based on Regional Hotspots and Clustering Method

Abstract : Based on each unit of Nong’an County, With ArcGis software platform, the establishment of a part of the total nitrogen in the soil attribute data Nong’an topsoil fertility resources, phosphorus, potassium and organic matter and effective nutrient database, Global Clustering and outlier analysis and hot spot analysis of the autocorrelation method, the county topsoil fertility resources were analyzed and evaluated. The results for farmland protection and optimal layout policy to provide a reference for the theory and methods, but also on the implementation of the agricultural work provides precise basis for decision making.
