哈密市戈壁表层土壤理化性质及质量现状
Physicochemical characteristics and quality assessment of Gobi soils,Hami City,China
摘要
Abstract
Soil quality is essential for vegetation cover and ecological recovery in Gobi zones.In this study,we analyzed 56 typical soil samples from the Hami Gobi to evaluate soil texture,salinity,and nutrient characteristics using eight indices,including soil moisture content,soil bulk density,pH,total salt content,organic matter,total nitrogen,total phosphorus,and total potassium.Based on these indices,we constructed a soil quality index(SQI)for a comprehensive soil quality assessment.The results revealed that soil quality in the Hami Gobi region was generally low,characterized by high gravel cover,low moisture content,severe salinization,and nutrient deficien-cy.The average soil quality in the Yiwu and Barkol regions was slightly higher than in the Yizhou zone,with bet-ter soil quality observed in areas where Gobi transitions into other land types.Overall,the SQI ranged from 0.4 to 0.5 across the Hami Gobi region and its subregions,showing a decreasing trend from north to south.This study highlights the urgent need for enhanced environmental protection and sustainable development strategies to copy with the impact of increasing human activities on the ecosystem.关键词
