土地人口承载力计算方法综述

随着人们对土地人口承载力的日益关注，国内外涌现出大量关于土地人口承载力的研究方法。文章将土地人口承载力的计算方法归纳为两大类：生产潜力推算法和直接计算法，并进一步总结了包含在这两大类中的多种计算方法；通过图表的方式比较分析了这些方法的适用范围、优点及局限性；指出了当前土地人口承载力研究中存在的一些问题；对其今后研究的发展趋势做了进一步的展望，最后，提出了深化研究的几点建议，即加强土地人口承载力的过程研究、预警研究、多因子要素研究和各类型区研究。

A Summary of the Calculating Methods on Population Supporting Capacity of Land

With the people focusing attention upon population supporting capacity of land increasingly, there are many calculating methods of population supporting capacity of land in China and abroad. The paper classifies the calculating methods of population supporting capacity of land into two categories, including land potential productivity calculating method and direct calculating method, it reviews many research methods in the two categories. Their applying scope, advantages and limits are discussed with illustrative diagrams. Meanwhile, the existed problems and the future prospect of population supporting capacity of land are given. Lastly, it proposes some suggestions：to strengthen the research of processes, early warning systems,essential factors and function regions.
