中国东部沿海地带人地关系状态分析

An Analysis on Man-Land Relationship of Eastern China

作为中国现代社会经济发展的主体发动机,东部沿海地区人地关系的演进状态和趋势不仅决定着地区自身而且决定着整个国家可持续发展的基本取向。有鉴于此,本文试图通过人地关系对应公式进行东部沿海地区人地关系演进状态的总体评价。评价的结果表明:第一,与中西部相比,东部沿海地区人地关系演进的实际紧张状态严峻的多,人地关系演进系数达到了2.13 (表观);第二,在地区人地关系的演进过程中,经济活动和人口集聚起着决定影响,其中尤以经济活动的作用最为关键,其贡献度达到75%;第三,未来人地关系状态的协调和改善主要取决于地区自身资源环境基础的扩展和改造能力。

As a key driving force of modern economy, the process of man-land relationship in eastern China has a decisive influence on sustainable development of both the whole country and the region itself. This paper is aiming at evaluating the general pattern of man-land relationship in eastern China through a cross-factor model, which refers to the interrelationship between regional resource-environment base (arable land, waters, minerals, forestry, and energy resources) and human activities (population growth and GDP increase). The findings of this paper could be concluded as the following: first, because of highly convergent human activities, a much more pressure on the man-land relationship of eastern China during the last 20 years has been proved when compared with both central China and western China; secondly, economic activity, rather than population growth, had a decisive influence on the highly intensified man-land relationship of eastern China; thirdly, in order to release the growing pressure on the man-land relationship of eastern China, it could be useful to reinforce the resource-environment base of eastern China itself by opening-up the region widely on the one hand, and improve the efficiency of resource-use through speeding up regional economic structure deeply on the other.
