【摘要】 采用遥感、GIS一体化技术,利用 1989~1990 年和 1999~2000 年获取的 LANDSAT卫星影像,对湖北省土地利用变化的区域分异特点进行分析。结果表明,自然地理环境因素对土地利用格局起主要控制性作用;城市化与工业化、社会经济的发展及国家有关土地利用政策对土地利用变化格局的形成起进一步调控作用。分区而言,鄂西、鄂东北、鄂东南等山区是耕地、林地与草地相互转换区;武汉、鄂州、黄石等沿江城郊区和从宜昌到沙市区沿江带是城镇扩张区;荆州、汉江下游和鄂北岗地丘陵是水域缩减区;江汉平原区是水域扩张区。另外,农村经济结构调整和有关耕地政策的出台是耕地、林地与草地相互转换区土地利用变化的主要驱动因素;中心城市对周围区域经济的带动作用和沿江区域特殊的交通优势是城镇扩张区的主要驱动因素;经济利益的驱动是水域扩张区的主要驱动因素;耕地政策是水域缩减区的主要驱动因素。更多还原

【Abstract】 With the use of integration of Remote Sensing and GIS and the Landsat image acquired in 1989~1990 and 1999~2000 respectively, we analyzed the area differentiation characteristics of land use change pattern in Hubei Province. The result shows that physical geography is control factor of the land use change; the Urbanizatiion and industrialization, the development of society economy and the policies of land use change are the modulate factors of it. The south, the north-east and the south-east mountainous area is the farmland, woodland and grassland region, in which they changed with each other; the suburb of Wuhan, Ezhou, Huangshi, and the area from Yichang to Shashi along the Changjiang River is the outstretched town region; Jingzhou, the lower reaches of Hanjiang River and the north hillock area is the water shrank region; Jianghan Plain is the outstretched water region. In addition, the adjustment of economy structure and the policy about land are the primary driving factors for the conversion among farmland, woodland and grassland; the advantage of economy around central cities and the traffic along river are the leading driving factors for towns outstretching; pursuing economy profit is the significant driving factor for water outstretching; the land policy is the main driving factor for water shrank.更多还原
