西南山地城乡聚落共生系统演进机理研究——以云南省为例

Urban-rural settlements is basic component of man-earth system,and spatial morphology of man-earth relationship evolution.The mountains of southwest ,as a typical representative of China mountain,is one of areas which are famous for its most obvious characteristics of vertical zonality and geographical fragmentation in China as well as in the world. The urban-rural settlements which have developed from this space are relative dispersion,losed.in the meantime the dependence between urban-rural settlements is relatively obvious. To promote the new-type urbanization should respect its evolution.Coordinated urban-rural development of the mountains of southwest will be different from the eastern plain area.Basing on the reality of long-term coexistence of urban and rural settlements under the southwest complex mountainous environment, and in order to intend to break through the limitations of previous research which separated space and time of devolopment of urban and rural settlements in mountainous areas,the study analyses exogenous environment basis, endogenous factor and symbiotic space-time model, etc. by combining concept of ecological symbiosis and geographical spatio-temporal. And thus explores basic laws of synergistic evolution about mountain symbiotic system of urban and rural, future trend, path selection and layout rearrangement.Such research will not only further more enrich the human geography, but alsoprovide a kind of creative thinking and exploring ways for promoting the new-type urbanization strategy and implementing "urban mountain" policy of Yunnan.

城乡聚落是人地系统的基本组成部分，是人地关系演进的空间组织形态。作为中国山地的典型代表，西南山地是世界垂直地带性和地理破碎性最为明显的区域之一，以此为空间载体所演化的相对分散、封闭的城乡聚落相互依赖程度明显，具有突出的地域独特性和共生性，注定要走一条有别于我国东部平原地区的新型城镇化道路，而揭示这种城乡聚落演进规律，是促进山地城乡协调发展的基础所在和客观需求。本研究基于地理学时空观理念，引入生态学系统共生理论，突破以往割裂山地城乡聚落互动依存和共生发育的二元分离研究方式，剖析山地城乡聚落系统共生环境基础、要素构成、时空模式等问题，揭示山地城乡聚落共生系统演进机理，提出未来山地城乡聚落共生系统时空协同的路径选择和布局，探索山地城乡聚落协调发展的科学研究理论和方法，为丰富人文地理学研究内涵做出有益尝试，也为推动国家新型城镇化战略和和云南实施"城镇上山"政策提供提一种创新思维和区域实践依据。

城乡聚落是人地系统的基本组成部分，是人地关系演进的空间组织形态。作为中国山地的典型代表,西南山地是世界垂直地带性和地理破碎性最为明显的区域之一，以此为空间载体所演化的相对分散、封闭的城乡聚落相互依赖程度明显，具有突出的地域独特性和共生性，注定要走一条有别于我国东部平原地区的新型城镇化道路。项目主要基于地理学时空观理念，引入生态学系统共生理论，突破以往割裂山地城乡聚落互动依存和共生发育的二元分离研究方式，强调地理学综合观，将聚落看作为连续发展的有机整体，研究突出集镇在城乡聚落发展演变中的重要作用，三分聚落为城市、集镇、农村。在剖析西南山地城乡聚落系统共生环境和解构共生要素的基础上，围绕西南山地城乡聚落协调发展主线，一方面，从城乡聚落共生系统层面剖析西南山地城乡演变历程及二元化演进特征，并构建评价指标体系和方法，分析城乡聚落共生系统协调发展程度。另一方面，针对西南山地城乡聚落发展阶段特征，创新性地将分形理论引入集镇体系研究，探究山地环境下发育的集镇体系规模、空间结构和服务范围，多维度揭示其分形发育影响因素及形成机理，提出未来山地城乡聚落共生系统时空协同的路径选择和思路对策，探索山地城乡聚落协调发展的科学研究理论和方法，为丰富人文地理学研究内涵做出有益尝试，也为推动国家新型城镇化战略和云南实施“乡村振兴战略”政策提供一种创新思维和区域实践依据。
