随着国家生态文明建设、新型城镇化、乡村振兴等重要战略的实施，乡村地域成为国家经济转型发展的重要支撑点和政府及社会投资的重要领域，各类建设需求大幅增加，迫切需要对乡村空间进行深入认知与研究。国家空间规划体系改革又对乡村空间规划变革提供了新的发展机遇和编制要求。乡村地域随着自身的不断深化发展，其优化国土空间格局的内生需求愈发强烈。将“三生”空间发展理念与生态文明建设、新型城镇化和乡村振兴等战略实施中，可有效调和乡村“生产——生活——生态”空间发展中的各项矛盾。乡村“三生”空间的研究意义就在于能够清晰且深入地理解乡村空间发展内涵，全面把握新时期下乡村发展的空间需求。因此，本研究通过理论研究和国内外实践经验总结，提出新时期乡村空间研究过程中亟待回答的三个核心问题，并围绕此构建“三个问题、八大内容、两个层次、三类策略”的解释性研究框架。 在“三个问题、八大内容、两个层次、三类策略”的解释性研究框架下，从“三生”空间的理论基础、逻辑联系与制衡关系和系统特性着手，对“三生”空间的理论特性进行分析，构建乡村“三生”空间的识别依据。通过对不同规划角度下乡村“三生”空间的差异特征分析，明确乡村“三生”空间识别与分类的依据选择范围和技术操作准则。然后，通过对我国现行空间性规划特点与弊端分析总结，以及对国外空间规划体系的经验借鉴，从数据标准、用地分类标准、数据库管理及坐标系等方面提出乡村“三生”空间识别思路框架和实际所需的技术准备。 围绕乡村“三生”空间类型的科学识别与空间功能的量化评价两大核心科学问题，以武汉市乡村作为实证研究样本，对武汉市现状城乡空间格局和乡村基本特征进行深入分析，构建了具有针对性的乡村“三生”空间分类体系和乡村“三生”空间功能评价体系。对武汉市乡村“三生”空间进行科学识别和空间功能测度，并进一步对“三生”空间的集聚状态与融合情况进行分析，对武汉市乡村“三生”空间分布情况和功能价值进行详细刻画，综合且全面地反映武汉市乡村“三生”空间的现实情况与空间优化基础。 围绕乡村“三生”空间变化的作用机制这一核心科学问题，运用前文构建的乡村“三生”空间分类体系和空间功能评价体系对2011年武汉市乡村“三生”空间进行识别与评价。将测度结果与2016年的进行比较分析，总结武汉市乡村“三生”空间变化特征。并基于武汉市乡村“三生”空间变化特征对未来乡村发展趋势进行总体判断。在此判断基础上，通过PRA参与式乡村评估调研方法获取在地村民调研数据，运用Tobit回归模型对乡村主体的空间优化意愿进行分析，运用结构方程模型对乡村主体的空间满意度进行分析。然后进一步引入行动者网络理论，构建基于行动者网络理论的解释性分析框架，对乡村空间行动者进行筛选，提出本次行动者网络的强制通行点，对乡村空间行动者网络呈现的新特点进行分析总结。 最后，基于前文对乡村“三生”空间类型的科学识别、空间功能的量化评价和空间变化的作用机制三大核心问题的分析结论，针对宏观层次研究结果提出全域统筹的乡村“三生”空间引导策略，分类引导的乡村“三生”空间协调策略，针对微观层次研究结果提出差异引导的乡村“三生”空间功能发展策略。 本研究在明确乡村“三生”空间内涵的基础上详细分析了其理论基础、识别分类方法、功能评价体系、变化作用特征及内在作用机制，并基于此提出了宏观至微观层面的乡村“三生”空间优化策略，丰富了乡村空间相关研究，为后续乡村空间发展转型提供借鉴和指导。 关键词：乡村空间，“三生”功能，空间优化，武汉市

 With the implementation of important strategies such as national ecological civilization construction, new-type urbanization and rural vitalization, rural area has become an important supporting point of national economic transformation and development, and also an important field of government and social investment. The demand for various types of construction has increased substantially, and it is urgent to rural space for in-depth cognition and research. The reform of the national spatial planning system has also provided new development opportunities and requirements for the compilation of rural spatial planning. With the continuous deepening of the development of rural areas, the endogenous demand for optimizing the spatial pattern of land becomes more and more intense. The implementation of the “Production-Life-Ecology”space development concept and the implementation of ecological civilization, new urbanization and rural revitalization can effectively reconcile the contradictions in the development of the rural “Production-Life-Ecology” space. The research significance of the rural “Production-Life-Ecology” space lies in the clear and in-depth understanding of the development of rural space and the comprehensive understanding of the spatial needs of rural development in the new era. Therefore, this study summarizes the three core issues that need to be answered in the process of rural space research in the new era through theoretical research and practical experience at home and abroad, and construct the explanatory research framework of “three problems, eight major contents, two levels ,three types of strategies”. Under the framework of the interpretative research of “three problems, eight major contents, two levels ,three types of strategies”, this study starts form the theoretical basis, logical connection, checks and balances and system characteristics of the “Production-Life-Ecology” space, analyzes the theoretical characteristics of the “Production-Life-Ecology” space and constructs the identification basis of the rural “Production-Life-Ecology” space. Through the analysis of the difference characteristics of the rural “Production-Life-Ecology” space under different planning angles, the selection range and technical operation criteria of the rural “Production-Life-Ecology” space identification and classification are clarified. Then, through the analysis and summary of the characteristics and drawbacks of China's current spatial planning, and the experience of foreign space planning system, this study proposes the framework of rural “Production-Life-Ecology” space recognition and the technical preparations that are actually needed from the aspects of data standards, land classification standards, database management and coordinate system. Focusing on the two core scientific issues of scientific identification and spatial function quantitative evaluation of rural “Production-Life-Ecology” space types, this study takes the rural areas of Wuhan as an empirical research sample to analyze the spatial pattern of Wuhan and the rural basic characteristics, and constructs the spatial classification system of rural “Production-Life-Ecology” and the evaluation system of rural “Production-Life-Ecology” spatial function. This study carries on the scientific identification and the spatial function measure to the rural “Production-Life-Ecology” space in Wuhan, and further analyzes the gathering state and the fusion of the “Production-Life-Ecology” space. This study describes in detail the spatial distribution and functional value of “Production-Life-Ecology” in rural areas of Wuhan, and comprehensively reflects the reality and the basis of spatial optimization of the “Production-Life-Ecology” space in rural areas of Wuhan. Focusing on the core scientific problem of the mechanism of the spatial change of rural “Production-Life-Ecology” space, the spatial classification system and the evaluation system of spatial function of rural “Production-Life-Ecology” space were used to identify and evaluate the “Production-Life-Ecology” space of Wuhan in 2011. This study compares the measurement results with that of 2016, and summarizes the spatial variation characteristics of rural “Production-Life-Ecology” in Wuhan. Based on the spatial characteristics of the “Production-Life-Ecology” in rural areas of Wuhan, the overall judgment of future rural development trends is made. On the basis of this judgment, the PRA participatory rural assessment research method is used to obtain the survey data of the local villagers. The Tobit regression model is used to analyze the spatial optimization willingness of the rural subjects, and the structural equation model is used to analyze the spatial satisfaction of the rural subjects. Then further introduce the actor network theory, construct an explanatory analysis framework based on the actor network theory, and screen the rural space actors, and put forward the mandatory access point of the actor network. The new characteristics of rural spatial actors network are analyzed and summarized. Finally, based on the previous analysis of the three core issues of the rural “Production-Life-Ecology” spatial types, the quantitative evaluation of the spatial function and the mechanism of the spatial change, In view of the macro-level research results, this study puts forward the spatial guidance strategy of “Production-Life-Ecology” in rural areas, and the spatial coordination strategy of “Production-Life-Ecology” in rural areas, which is guided by classification and guidance. According to the research results of micro-level, this study puts forward the development strategy of rural “Production-Life-Ecology” spatial function guided by difference. On the basis of defining the spatial connotation of “Production-Life-Ecology” in rural areas, this study analyzes in detail its theoretical basis, methods of identification and classification, functional evaluation system, characteristics of changes and internal mechanism of action. Based on this, this study puts forward the optimization strategy of rural “Production-Life-Ecology” space from macro-level to micro-level, which enriches the relevant research of rural space. This study enriches the research on rural space and provides reference and guidance for the subsequent development of rural space development.
