摘要
本文系统梳理了土壤环境承载力的概念和发展历程,总结了土壤环境承载力的多种评价方法,包括系统动力学模型法、综合模型评价法、PSR和OER模型评价法、环境质量评价法等,并比较了现有评价方法的优缺点;归纳了土壤环境承载力的评价指标体系,同时给出了土壤环境承载力的应用场景.在此基础上提出了土壤环境承载力研究的不足之处和未来的研究方向.
Abstract
This paper systematically reviews the development history and concept of soil environmental carrying capacity,summarizes various evaluation methods of soil environmental carrying capacity,including system dynamics model method,comprehensive model evaluation method,PSR(Pressure-State-Response)and OER(Object-Endurance-Recovery)model evaluation method,and environmental quality assessment method,and compares the advantages and disadvantages of existing evaluation methods.Furthermore,the paper summarizes the evaluation index system for soil environmental carrying capacity and presents its application scenarios.Based on this,it was put forward that the shortcomings in the current research on soil environmental carrying capacity and the future top-priority research directions.
