"后三峡时代"库区人居环境品质提升理论与方法

With the completion of the three gorges project, the construction of migrates resettlement has been completed. Although, the great achievement of TGP (Three Gorges Project) has been achieved, many problems still exist on regional development， resources utilization，population gathering，town and country construction，land conversion，migrates smoothly get rich，geology disaster prevention, especially the requirements of comfortable living environment and to get rich has been further strengthened. And its Human Settlement Quality Promotion and optimization become one of the research hotspots in the study of the Three Gorges Reservoir area on the "Post-Three Gorges era". Taking "Human Settlement Quality Promotion" as core, taking"optimize the towns overall spatial pattern- - promote residential quality for migrate- - guarantee ecological and safety on town construction"as logical sequence, this project do research to the issues on poor resident environment、 ecological deterioration、geological disasters. It emphasize the hierarchy and multidimensional on the study, and discuss the core driving mechanism of the change on towns overall spatial pattern in the Three Gorges Reservoir area, emphasize "migrate residential district" this core problem from the"Time - - space - - humanity" trinity Angle of view. And it will exploring a way to hierarchical control and carry out diagnosis & precaution for safety planning, to establish technical support for Human Settlement Quality Promotion in the Three Gorges Reservoir area.

随着三峡工程的完工，库区移民搬迁建设基本完成，三峡工程在发挥巨大综合效益的同时，库区在区域开发和资源环境利用、人口集聚和城乡建设土地转换、移民安稳致富、生态环境保护、地质灾害防治方面还存在大量的问题，特别是库区移民对于居住环境和致富的要求进一步加强，其人居环境品质的提升及优化成为三峡库区在"后三峡时代"研究的热点问题之一。课题以"人居环境品质提升"为核心内容，针对"后三峡时代"库区面临的移民居住环境较差、库区生态环境恶化、地质灾害突出等问题，以"城镇总体空间格局优化- - 移民住区品质提升- - 城镇建设生态与安全保障"为逻辑进行研究，强调研究的层次性与多维性，从"时间-空间-人文"三位一体的视角，探讨库区城镇总体空间格局变化的核心驱动力机制，突出移民住区这一核心问题，拟建立安全规划层级控制与实施诊断预警方法，为库区空间品质的提升建立技术支撑。

三峡工程和库区移民搬迁建设主体工程完成后，在城镇化快速发展阶段，库区人居环境建设在经济发展、资源利用、生态环境保护、土地利用、灾害防治等方面仍然面临着诸多问题，因此其人居环境品质的提升及优化成为库区在“后三峡时代”重要工作之一。课题以“人居环境品质提升”为核心内容，从要素耦合的规律性和有机性凝练出三峡库区人居环境品质提升的一般过程：即优化库区城镇总体空间格局——提升移民住区人居环境品质——保障库区生态环境安全三个层面，研究涉及人居环境建设的多方面，包括整体资源条件、生态环境容量、土地利用、历史文化、空间品质、经济社会、灾害防治等。项目运用城乡规划学、土地科学、景观生态学、建筑学、地理学等领域的理论与方法，结合库区人居环境建设难题及建设发展实际需求，从土地集约利用模式、经济与城镇协调发展、旧城和地下空间品质提升、生态防灾等多个方面提出创新理论与规划方法，促进实现“后三峡时代”库区可持续发展。研究对库区人居环境品质提升和稳定库区城镇建设与社会与经济相协调、促进“后三峡时代”移民人居环境可持续发展具有至关重要的意义。
