Study on the Spatial Layout of Park Green Space (PGS) in Maonan City for the Concept of Low Carbon

In the background of ecological civilization and new concept of low carbon, this study aims to explore the spatial layout of Park Green Space (PGS) and urban area in Maonan District of Maoming City by means of GIS-based spatial analysis method in combination with forest inventory and related theories of PGS. Meanwhile, using the inventory survey method which have 2705 trees were acquired and measure for assessing the carbon sequestration and market value of the forest in the PGS discussing the contribution rate of carbon sequestration of the park vegetation, conducting quantitative analysis and evaluation, and finally comprehensively assess the relationship between the PGS and carbon sequestration as well as urban spatial morphology. According to the results of spatial analysis, the spatial layout of urban PGS system in Maonan District does not meet the national standards, as well as is showing insufficient and imbalance. In the end, according to the existing problems of urban green space construction and the future development of the city, the corresponding countermeasures for urban PGS construction are proposed. It includes improving the spatial layout of urban PGS, improving the low-carbon economic carbon fixation benefits of PGS vegetation, and building a scientific and reasonable urban green space system to address the problems in the process of urban development.
