福建上杭土壤地球化学特征及质量现状

Soil Geochemical Characteristics and Quality Status in Shanghang County of Fujian Province

依据福建上杭农业地质调查评价数据,研究了县域耕地和园地表层土壤养分和重金属元素的分布特征,分析了不同控制因素下土壤各项指标的地球化学特征。研究结果表明,上杭县表层土壤元素含量主要受控于地质背景,同时不同土壤类型、地貌类型均对土壤元素含量有一定的影响。通过划分上杭县耕地和园地表层土壤的养分等级、环境等级及质量等级,调查成果可以为地方上科学精准施肥、土地利用规划等提供基础数据支撑。

According to the evaluation data of agricultural geological survey in Shanghang County,Fujian Province,the distribution characteristics of soil nutrients and heavy metal elements in the surface layer of cultivated land and garden land in the county area were studied,and the geochemical characteristics of soil indicators under different control factors were analyzed.The research results show that the content of surface soil elements in Shanghang County is mainly controlled by the geological background,and different soil types and landform types have certain effects on soil element content.The nutrient grades,environmental grades and quality grades of the surface soils of cultivated land and garden land in Shanghang County are divided.The survey results can provide basic data support for scientific and precise fertilization and land use planning at the local level.
