Historical Research On Urban Eco-spatial Structure In Classical Southwest Mountainous City

This Paper belongs to the subject:《The Theory and Case Research on UrbanEcological in Southwest Mountainous city in China》, which is the important part of《The Theory and method on Urban Suitability in Southwest Mountainous city(town)in China》. The research system of the subject include five parts which reflect the urbanecosystem, it includes: Eco-spatial structure, Ecological culture, Ecological landscape,Ecological security, Ecological elements, and this paper researches the history ofclassical southwest mountain city eco-spatial structure. As the opening of the wholeissue, In order to avoid duplication of research and to the form the subject system, Thispaper focus on the historical evolution of the urban ecological spatial structure, andfocus on the integration of the relationship between urban ecological spatial structureand urban spatial structure in history.Urban ecological space is the hardware environment and space-based of the urbanecosystem. The city eco-spatial structure grasps the overall framework of the urbanecological space, and it integrates the constituent elements of ecological space, it is theexpression of the constituent element’s organizational form and order, and it brings upthe basic Figure-ground relation between urban ecological space and urban constructionspace, and it also plays the ecosystem services function of urban construction space.This Paper focus on the city eco-spatial structure, combed theory with examples,based on the regional point of view of “Southwest Mountains”, using the three timeperiods——remote antiquity, ancient, modern for clues. The paper also studies thetheoretical basis, organizational models and examples, and depth analysis developmentcharacteristics and formation mechanism of every historical stages, summarizes itscharacteristics and impact, sorts out the development context of it, and summarizes theexperiences of the previous construction aspects of it, obtains the history basis of thebasic value criteria, in order to resolve the historical evolution of laws and mechanisms,provide the advice for the contemporary urban ecological spatial structure optimization.First, builds the research framework, defined the scope of study, the connotation ofstudy, and the key issues. Explain that the emphasis of research is the organizationalmodel of the spatial structure of urban ecological and its evolution law and historicalmechanisms, and then, induction on the Mountains of Southwest native of the regionalecological environment characteristics as the basis for the study. Second, divided into the remote antiquity, ancient, modern three time periods,In-depth analysis organization model and typical cases, advantages and disadvantages,characteristics of phase and the major influencing factors of city eco-spatial structure inSouthwest Mountainous city in different historical stages.The key of an remote antiquity part is to analysis the history of civilization originand native settlements in Ba、Shu、Dianqian、Zang these five regions; The key of anancient part is to analysis the relationship between mountain and city、river and city、field and city, and then, summed up the excellent construction method of ancient. Thekey of modern part is to analysis the evolution process of the relationship betweeneco-spatial and urban space, on the basis of this, analysis the modern evolution of thecontradictions and problems.In the end, the paper analysis the historical, it is includes that the analysis of thehistorical evolution and its rule and the historical development mechanism, and on thebasis of this, extraction the enlightenment of the contemporary southwest mountain cityeco-spatial structure, in order to establish scientific ecological values. At last, uses theactual project as an example to give some advices to improve the southwest mountaincity eco-spatial structure.
