重庆丰都长江以北地区土壤养分元素地球化学及影响因素
Geochemistry of soil nutrient elements and its influencing factors in the area north of the Yangtze River,Fengdu,Chongqing
摘要
Abstract
Based on the collection and analysis of topsoil samples from the cultivated area north of the Yangtze River in Fengdu County,Chongqing City,this study investigated the concentrations,spatial distribution,and influencing factors of soil nutrient elements,as well as their correlations with soil type,land use type,pH,and organic carbon.The results indicate that Mo,Ca,B,S,and organic carbon are relatively deficient in the topsoil of the study area.Land use type is the primary factor affecting soil N,S,and P contents,whereas soil type,organic carbon,pH,and elevation are secondary factors.Soil N and S contents show strong correlations with soil type.Additionally,soil organic carbon is highly correlated with N and S,suggesting that the accumulation of organic carbon promotes the enrichment of N and S in the soil.关键词
