摘要： 根据土地利用和相关的社会经济状况及其变化特征分析,提出了表征县域土地利用变化及其人类驱动因素的指标,分析了二者的联系以探讨人类驱动因素对土地利用变化的驱动机制,指出了人类驱动因素在解释土地利用变化过程中的贡献,为协调喀斯特地区土地资源和人类活动的关系提供依据,为进一步进行土地利用/土地覆盖变化研究积累方法和经验。

关键词: 土地利用变化, 人类驱动因素, 驱动机制, 喀斯特地区

Abstract: Based on the analysis on the characteristics of land use change and its related social and economic conditions in the past ten years in some typical counties of Guizhou Province, an index system representing land use change and human driving forces is submitted in this paper.Upon these indices, a relationship between land use change and human driving forces is discussed to reveal the mechanism of land use change under the driving of human forces and the relative weight of the driving forces.The result from factor ananlysis shows that the amount of food of per capita and the ratio of agricultural population are more important in driving the land use change.The correlation coefficients between the indices representing land use and driving forces tell the connection between factors, and population density and grain production are correlated more closely with the land use indices.The contribution of human driving forces to land use change in the study area is studied by the method of multiple regression, from which we can conclude than human driving forces can interprete the land use change at the level of 70%-90%.

Key words: land use, human driving forces, driving mechanism, Karst mountain area
