河北太行山区土地利用变化及其社会驱动机制分析

以河北太行山区为例,从土地利用动态变化入手,结合社会经济因素,定性与定量地探讨土地利用变化的驱动力;基于1987年和2000年两期遥感影像提取土地利用信息,分析土地利用类型数量、速度和结构等变化;通过构建土地利用结构与社会经济数据的相对变化数据库,建立社会经济驱动因素指标体系,对土地利用变化的驱动力进行相关分析和主成分分析;在定量分析基础上,从人口、经济、科技和政策等4个层面揭示其社会经济驱动机制.

The Driving Mechanism Analysis of Land Use Change of Taihang Mountain Area in Hebei

Taking Taihang mountain area in Hebei as example, taking social economy factors into consideration, this paper will have a qualitative and quantitative analysis of the driving forces of land use change. Firstly, from the remote sensing image in 1987 and 2000, we extract the land cover information and analyze the change of land cover types on the quantity, speed and degree. Secondly, based on the database of the land use structure and social economy data, by establishing the index system of social economy driving forces to have correlation analysis and principal components analysis, we have a quantitative research on the driving forces of land use change. Finally, we show the social economic driving mechanism on population, economy, technology and macro-strategy.
