Evolution Study on Green Urbanization Spatial Pattern of Poyang Lake Eco-Economic Zone Based on Spatial Autocorrelation

Poyang Lake Eco-economic Zone is an eco-economic demonstration area in harmony between mankind and nature. It is an imperative to develop a green urbanization road with coordination and harmony between ecological civilization construction and economic and social development in a bid to effectively protect local ecological environment. By beginning with the basic connotations of green development, the evolution trend of green urbanization spatial pattern is revealed and the influences of ecological environment on evolution of spatial pattern in the research. By building comprehensive evaluation index of green urbanization development level, the green urbanization development level of 9 representative prefecture-level cities at Poyang Lake Eco-economic Zone from 2008 to 2014 is measured through entropy evaluation method. Besides, the in-depth analysis on evolution process of spatial pattern is carried out. Meanwhile, spatial autocorrelation test is carried out with Moran'si index. From four perspectives such as economy, society, environment and social security, the influence factor variables are selected and analyzed by virtue of influences factors of spatial econometric model on spatial pattern evolution. According to the research, it manifests that green urbanization of Poyang Lake Eco-economic Zone shows high level aggregated distribution and high level area has the trend of spreading to the low level area. In addition, the area with good ecological environment also has high regional development level because of the great influence of ecological environment on spatial pattern.
