根据山地城镇建设的发展现状 ,运用遥感和地理信息系统技术 ,在获取、分析三峡库区综合环境指标如自然、技术、经济、城镇发展的区域状况等的基础上 ,以巫山县为例 ,建立了巫山县空间环境数据库 ,并提出了巫山县县城修建性选址模型。结果证明 ,好的迁建地多分布于长江及大宁河沿岸 ,交通条件较优越 ,靠近经济发达地区。此模型的建立可以为其它三峡库区城市迁建综合环境研究提供合理的方案和措施。

In order to resolve the problem which how to fast selects the location of a mountain city to relocate , we must obtain its integration environment data such as nature , technique , economy or region base of town development . Basing on analyses above data of Three-Gorge Reservoir , the paper expatiates on the development actuality of mountain town construction , establishes Wushan county spatial database and put forward to the rebuilding model of town construction to Wushan county by using tools of remote sensing and GIS. As a result, we can find better moving site frequently locate in the Changjiang river and along Changjiang river and area having superior traffic and developed district . The model would provide reasonable scheme of town construction and measure for other mountain town around Three- Gorge Reservoir.
