摘要: 由于各个自然要素及其空间组合的差异,不同自然地理单元的区域总体特征与主要的自然地理过程各不相同,导致了其内部土地利用变化时空形式与过程也不相同。吉林省前郭县可划分为四个自然地理单元区,各区内土地利用的基本模式不同,土地利用变化趋势各异。研究表明,土地利用变化动态过程和自然地理单元要素综合特征具有显著相关性。

关键词: 土地利用变化, 土地利用动态过程, 有效系数, 自然地理单元

Abstract: Different combinations of physical geographical elements induce the difference of spatio temporal pattern of land use change. There are four physical geographical units in Qianguo county of Jilin province. Based on spatial analysis and statistical analysis, we conclude that the primary pattern of land use and the tendency of land use changes are all different in four physical geographical units. Though land use change is mainly affected by social and economic conditions in a short period, the integrated character of the combination of physical geographical elements controls the land use dynamic process. The relationship between land use dynamic process and the character of physical geographical units is different in different units.

Key words: effective coefficient, land use change, land use dynamic process, physical geographical unit
