云南省姚安坝区1∶5万土地质量地球化学评价及开发建议
1∶50,000 geochemical survey-based assessment of land quality and land development suggestions for the Yao'an Dam area,Yunnan Province,China
摘要
Abstract
Land emerges as the most fundamental resource for agricultural production,and addressing land quality-related issues is the key to ensuring high food quality.A comprehensive understanding of land quality is crucial to the scientific and sustainable utilization and development of land resources.This study conducted a 1∶50,000 geochemical survey of land quality in the contiguous farmland in Dongchuan Town,Yao'an County,Yunnan Province.Accordingly,this study provided a comprehensive assessment of soil nutrients,environment,dry and wet atmospheric deposits,and agricultural irrigation water.Based on the assessment results,this study deter-mined the production areas of green food and pollution-free agricultural products,aiming to provide a reference for the development and utilization of sustainable,green cultivated land.The results indicate that soils in the study area are nutrient-rich and enjoy a favorable environment,high-quality irrigation water,and an excellent atmospheric environment.The comprehensive grade assessment results of soil quality align with those of land quality,revealing that the first and second-grade high-quality soils account for 68.98%of the total area.A batch of production areas of pollution-free and green food were determined,and those that can be directly used to develop green,zinc-and copper-rich crops were delineated.These findings will provide geochemical data support for land use planning,food security,building agricultural products with plateau characteristics,and serving rural revitalization efforts.关键词
