Study On The Coupling Relationship Between Urban Land Intensive Use And Low-carbon City

The coordinated development of city and low carbon city intensive land use is the key problem for the realization of green and low carbon economy. In this paper, through the analysis of previous research results, the city land is the material carrier of low carbon city development, city land intensive use level such as:city land use structure is reasonable, whether the city land with high ratio of input and output, the city land use economic, ecological environment, social harmony and so on in great influence and restriction low carbon city development. And put forward higher standards and requirements to the city land use environmental, social benefits of low carbon city. City land intensive use is not only the pursuit of maximum economic output, but rather through the maximization of land use structure, optimization of land space layout, land use control carbon emissions to the pursuit of economic, ecological environment, social comprehensive benefit the reasonable planning. City land intensive use has a relationship of mutual influence and restriction and low carbon city development. Only when the two factors form a harmonious and coordinated development relationship, can we realize the goal of development of green and low carbon economy.This article takes the Pearl River Delta of Guangdong Province as example, combining the theory with concrete evidence. First of all, based on the social and economic data of this region from 2005 to 2012, we build a comprehensive evaluation index system of urban land intensive use and low-carbon cities. Then we calculate the comprehensive value of each 9 cities in Pearl River Delta by entropy method. Secondly, building the coordinated development model of urban land intensive use and low-carbon city to calculate the degree of coupling coordination degree and coordinated development of the various cities from 2005 to 2012, which can explore the coupling degree between urban land intensive use and low-carbon city. In addition, in order to make research results more intuitive, the paper uses ARCGIS10.2 software, drawing a PRD 9 Land use intensive 2005,2008,2010,2012 comprehensive evaluation value, comprehensive evaluation value of low-carbon cities, urban land intensive use and The coupling of low-carbon urban space and coupling coordination degree distribution map, showing the coupling state of the coordinated development of spatial differences PRD nine urban land intensive use and low-carbon city.The results show that, first of all, the level of intensive use of land in various cities of the Pearl River Delta region as a whole has shown a steady upward trend, in which the comprehensive evaluation value Shenzhen, Guangzhou, Dongguan, higher than other cities. Presents a comprehensive evaluation of the level of the whole Pearl River Delta region of low-carbon city on the rise, but the rise is not obvious, where the level of low-carbon development in Guangzhou and Shenzhen significantly better than other regions. Secondly, the coupling coordination PRD intensive land use and low-carbon city is rising year by year, but not high coupling coordination, to 2012 in addition to the coupling coordination degree in Shenzhen, Guangzhou, Dongguan, in coordination phase, long-term in other cities disorders and mild to moderate stages of disorders; and Shenzhen, in addition to the coordinated development of the other eight cities showed that intensive use of urban land restricts the development of low-carbon cities, intensive use of urban land there is a large room for improvement. Finally, based on the empirical results, this paper comes up several suggestions from the perspective of economy、ecological environment and society to promote the harmonious relationship between urban land intensive use and low-carbon city in Pearl River Delta.
