- Abstract:
-
Taking the south Jiangsu as an example, this paper firstly proposed a four-dimension indicator system, which was mainly based on the ‘basic-structure-threat-profit’ framework, and then comprehensively evaluated the land ecological quality. Further, the spatial pattern of regional land ecological quality was explored by using the spatial cluster analysis. Results showed that: (1) the global Moran’s I amounted to 0.79, and its significance level was 0.01, there was an obvious positive spatial autocorrelation, the low land ecological quality areas concentrated in the main city zone, while the high-value districts were in outlying rural zone, the low-value and high-value coexisted in the suburban areas, showing the evident gradient from urban to rural areas; (2) the results from Q-type hierarchical cluster analysis indicated that 33.33% of cities and counties under research could be classified into the group of harmonious development, 33.33% belonged to the group of imbalance development resulting from economic lag, while the rest 33.33% belonged to the group of imbalance development resulting from the degradation of land ecological quality, showing the even distributed proportion.
