摘要：

作者选择中国西部长城沿线农牧交错带的陕西省榆林市榆阳区、西北干旱区河西走廊的甘肃省酒泉市肃州区和西南四川盆地丘陵区的四川省德阳市中江县为3个典型研究区域,对20世纪80年代以来的农村社会经济统计资料、土地概查、土地详查、遥感图像判读以及136个典型农户调查进行分析发现:土地利用的变化既受自然的地球生物物理驱动力的制约,又受社会、经济、技术和历史等因素的影响,具有很强的综合性和地域性。西部地区具有悠久的土地开发历史,其土地覆盖类型多种多样。由于其特殊的自然地理特征和社会、经济、政治等驱动因素的复杂多变,本区的土地覆盖发生了很大的变化,这些变化同农业、林业、牧业等与土地资源利用有关的产业发展以及城市化和土地退化等可持续发展问题密切相关。影响西部地区土地利用变化的驱动因素主要是人口增长与城镇化、固定资产投入与工矿交通产业发展、经济结构调整、科技发展和政策管理等人文因素。

Abstract:

Three typical study cases were analyzed based on rural socio-economic statistical data,land survey and remote sensing image interpretation and 136 household questionnaires since 1980.All the three study areas are situated in the interlock area of farming and pasturing along the Great Wall,including Yulin city of Shaanxi province,Jiuquan district of Gansu province in Hexi Corridor of arid Northwest China,and Deyang city in hilly areas of Sichuan Basin. The results showed that land use changes have characteristics of integrity and regionality,which are not only restricted by natural geo-bio-physical mechanisms but also affected by other factors such as society,economy,technology and history.Western China has a long history of land reclamation and varies in types of land cover patterns.Dramatic changes in land use of western China have taken place since the beginning of the 21st century due to unique physiographical characteristics,and some complicated social,economic and political factors.These factors are closely related with land resources utilization relative to agriculture,forestry,and animal husbandry as well as sustainable development relative to urbanization and land degradation.Among these,human factors constitute the main driving forces influencing the region's land use change,including population growth,urbanization,fixed assets investment,development of industry,mining and transportation,economic restructuring,development of science and technology,and policy management etc.

Key words: western China, land use change, influencing factor, contrast analysis
