生活环境质量是当前我国城镇居民中最受瞩目的话题之一。以提升生活环境质量为目标的城镇规划策略研究具有重要理论和实践意义。本课题以川西北民族地区小城镇为例，以“生活环境质量”为研究对象，借助地理信息系统作为科学分析工具，构建生活环境质量评价指标体系，生成案例城镇生活环境质量的量化评价地图，并对不同规划政策影响下生活环境质量的未来情景进行模拟分析，进一步探讨小城镇生活环境质量与规划要素之间的关联机制，探索提升生活环境质量的民族地区小城镇空间规划策略。.本课题在研究对象、尺度、视角和技术方法层面对生活环境质量研究进行前沿探索，将生活环境质量的二维空间量化研究引入小城镇空间布局分析领域，并利用计算机技术模拟规划政策实施效果。本课题对提升民族地区小城镇生活环境质量，增强规划决策科学性具有重要的科学意义和研究价值。

Nowadays urban residents in China pay more and more attention to the quality of living environment. Enhancing the quality of living environment is the key issue for small town planning. The project takes the small towns in Northwest Sichuan ethinc region as case studies, with "the quality of living environment" as the research object. We use Geographic Information System as a scientific analysis tool to set up the evaluation index system of the quality of living environment and to achieve the qualitative evaluation result for case towns. The policy scenario of the quality of living environment will be simulated, and the characteristics and laws how the land use layouts affect the quality of living environment will be explored. The spatial planning strategies to enhance the quality of living environment will be brought out for those small towns in Tibetan region. .This project will provide enrichment and supplement for the existing research in research object, scale, angle of view and technical methods. The digital research of the quality of living environment will be introduced into space layout analysis field for small towns, and scientific tools will be used to simulate the planning policy effect. The project has important scientific significance and research value to improve the quality of living environment of small towns in Tibetan areas, and to scientifically enhance the planning decision-making process.
