安徽省郎溪县土壤养分空间分布特征及影响因素研究
Study on Spatial Distribution Characteristics and Influencing Factors of Soil Nutrients in Langxi County
摘要
Abstract
In order to reveal spatial variation of soil nutrients in Langxi county in Anhui province,and clari-fy spatial distribution patterns and key driving factors,based on traditional statistics,geographic informa-tion systems(GIS),and geographic detector models,the content characteristics,spatial distribution pat-terns and dominant influencing factors of eight nutrient indicators,including nitrogen,phosphorus,potas-sium,organic matter,boron,manganese,selenium and molybdenum in 4054 surface soil samples from Langxi county have been analyzed systematically.It is showed that all nutrient indicators exhibit moderate variability.The spatial differentiation of soil nitrogen,phosphorus and organic matter is mainly controlled by land use types.The spatial distribution of potassium and boron is mainly dominated by geological back-ground.The spatial variation of manganese is influenced by synergistic effect of terrain and land use types.The spatial differentiation of selenium and molybdenum is influenced by a combination of geological back-ground,topographical conditions and land use types.关键词
