基于内蒙古黄河南岸灌区的土壤质量评价卡制定研究
A soil quality assessment card developing based on the south irrigation area of the Yellow River in Inner Mongolia
摘要
Abstract
In order to apply soil quality assessment results on practical production,this study focuses on the southern bank of the Yellow River in Inner Mongolia,a crucial agricultural production zone in the arid and semi-arid regions.A total of 11 physical and chemical indicators of 67 soil samples collected in this region were measured.Based on the optimal combination of methods,the soil quality index was calculated and a comprehensive evaluation was conducted using an obstacle factor diagnosis model and Kriging spatial interpolation to provide essential information for the soil quality assessment card developing in the study area.The results indicate that:The overall soil quality index in the study area ranged from 0.25 to 0.71,with an average value of 0.47.The levels of available phosphorus and potassium were relatively high,whereas the organic matter content was low.The soil water content and porosity were identified as the primary limiting factors for soil quality with obstacle degrees of 0.173 and 0.160,respectively.The soil quality exhibited a spatial trend of being higher in the eastern and southern regions and lower in the central and northern regions,which correlated with the distribution of soil water content in the east-west direction and porosity in the north-south direction.The soil quality assessment card developed from the comprehensive evaluation results included five chemical and two physical indicators.The card innovatively integrated grading standards for regional evaluation indicators and spatial distribution maps of soil quality,providing a practical method for calculating the soil quality index from different indicator datasets.Soil quality surveyors can fill out the card using the provided information in conjunction with the measured indicators,ultimately provide users with intuitive soil quality information.In conclusion,the formulation of the soil quality assessment card represents a significant advancement in integrating scientific research with practical agricultural practices,providing a crucial foundation for the protection and utilization of regional soil quality and agricultural management.关键词
