摘要： 土地利用在不同的经济发展阶段表现出不同特点。广西江州区属于我国西部经济欠发达地区,经济发展正处于工业化初期的起步阶段,土地利用变化特点主要表现为:以农业生产用地和生态用地竞争为主,耕地变化是土地利用变化的主要内容;建设用地低效、缓慢增长,农村居民点增长面积占较大比重;人均农村居民点面积逐渐增加。以1978—2002年的统计数据为基础,用主成分分析和回归分析相结合,对耕地面积变化的驱动力进行了研究,结果表明:人口增长、经济发展和土地管理使得耕地面积不断增长,收入和消费的提高以及农业产业结构调整导致耕地面积减少。发达地区的发展历程表明,经济高速发展必然引起农地快速非农化,江州区在土地利用中,必须注意节约用地,保护耕地,减少土地资源浪费,防止环境污染,实现区域土地的可持续利用。

Abstract: The characteristics of land use are different in each phase of economic development.As one of the developing areas in West China,economic development in Jiangzhou is below the nation's average level and still belongs to the initial stage of industrialization.With a leading agriculture and low industrialization level,Jiangzhou shows the typical characteristics of land use in this economic stage,which are:the competition between farmland and land for environment purpose constitute the main contents of land changes;slow enhancement of construction land in constrast to the greater proportion of rural settlements in Jiangsu Province;and rural inhabitant area per capita going up gradually.Based on statistical data from 1978-2002,the driving factors of arable land changes are studied by principal component method and regression analysis.The results show that economic development,population growth and land management led to the constant expansion of the cultivated land while the enhancement of income and consumption level and the adjustment of agricultural industry structure resulted in the reduction of the arable land.The rapid economic development will bound to cause rapid conversion of farmland into land for non,agricultural purpose.As a result,more attention will be given to protecting arable land,reducing waste of land,preventing environmental pollution,and realizing sustainable regional land use.

Key words: changes of land use, economic development phases, driving force, less developing area
