Research On Measuring Land Use Patterns Of Mega-city Regions Based On Sustainability

In the context of China’s new urbanization, this dissertation focus on theproblems and issues encountered in the development of mega-city regionsbased on sustainable perspective. The challenges in the process of sustainabledevelopment are more complicated for mega-city regions. Meanwhile, Landuse patterns significantly affect the space production and consumption,thereby affecting energy, environment and global sustainable development.Therefore, the research based on land use patterns is of great significance.Mega-city regions represented by London, Paris, New York, and Tokyo havecarried out sustainable-goals research and practice. Beijing is facing similarproblems with above regions, but has its own situation. How to accuratelyidentify and understand patterns of land use in mega-city regions becomes afundamental issue in seeking sustainable development and achievingadvantages in global competition.Firstly, this paper clarifies the concept and connotations of ‘land-usepatterns and sustainability’, and reveals based on the three aspects of land-usepatterns, objectives of latter are comprised of formal objectives specific to thecompact degree of land-use, and functional objectives specific to improve thestructure accessibility, as well as cooperative objectives of both form andfunction specific to land-use efficiency.Secondly, A multi-indicator method is identified to represent land-usepatterns based space matrix and buffer analysis, which contains six formindicators, four function indicators, and four cooperation indicators. With themethods of combining artificial interpretation and stratified random sampling,Combined with data processing, error analysis, comparison validation,scenario analysis and other sectors, this research measures land use patterns offive mega-city regions from two-dimensional to three-dimensional. Therebythe correlations between indicators of land-use patterns and sustainabledevelopment are analyzed. Finally, based on the conclusions of the measuring, referencingexperiences of typical mega-city regions, this research suggests theapproaches on form, function and cooperation based on advantages anddisadvantages of Beijing land-use pattern.This paper has been proposed more comprehensive measuring methodsbased on others study. Studies reveal different mega-city regions have its owncharacteristics, while different mega-city regions in land-use patterns andsustainability also has a relatively consistent basic law: that moderatelycompact of form, good accessibility on function, cooperative between formand function are essential for sustainable land use patterns. Land-usesustainability manifests as several characteristics: the higher the intensity ofland use, sufficient permeable ground and open space, high diverse and mixdegree functions, high integrity and quality of public green space system, railtransportation-guided land use form, functional layout and integrative citycenter in coordination with regional ecological system.
