西南区人地关系演进状态综合评价

采用多要素综合的人地关系分析方法,对西南区的人地关系演进状态进行总体评价.认为:①西南区资源环境基础薄弱,人地关系演进状态日趋紧张;②人口增加和经济活动是西南区人地关系演进过程的决定因素,其中人口增加作用最为关键;③西南区未来人地关系状态的协调主要依赖于人口增长速度的严格控制和资源环境支撑能力的提高.

An Analysis of Man-Land Relationship in Southwest China

As an undeveloped economic-region and important ecologic-barrier of the Changjiang valley,the process of man-land relationship in southwest China not only decides strategic direction of the great exploitation in west China but also influences sustainable development of the whole country. This paper is aiming at evaluating the general pattern of man-land relationship in southwest China through a multi-factor synthetical method,which refers to the interrelationship between regional resource-environment base and human activities.The new findings of this paper could be concluded as the following: first,resource-environment base in southwest China is unsubstantial,and man-land relationship in southwest China is becoming more and more uptight; secondly,population growth,rather than economic activity,had a decisive influence on the uptight man-land relationship of this region;and thirdly, in order to release the growing pressure on the man-land relationship of southwest China,it could be useful to control population growth and improve the efficiency of resource-use through speeding up regional economic structure deeply on the other.
