- Abstract:
- In order to promote the ecological use of land and implement the strategy of ‘ecological civilization', we conducted land use benefit evaluation from the perspective of low-carbon ecological city development. Taking the nine cities in the Pearl River Delta city as an example, we constructed a land use benefit evaluation index system based on the perspective of a low-carbon ecological city. The relative entropy combination weighting method, comprehensive evaluation method and obstacle degree model were used to explore the spatial and temporal evolution characteristics and obstacle factors of land use benefits of the nine cities in 2010 and 2017. The results show that:(1)the land use benefit levels in cities had a ‘core—periphery' structure in space, and the three cities such as Guangzhou, Shenzhen and Dongguan located in the Guangshen Science and Technology Innovation Corridor were significantly better than other cities; the level of the overall benefit had been steadily increasing; the largest increase of benefit was found in Huizhou, and the smallest increase of benefit was found in Zhaoqing;(2)the economic, social and ecological environmental benefits of land use had shown obvious hierarchical levels in cities, and the economic and social benefits had increased rapidly and were all positive; the growth rate of ecological and environmental benefits was small, and some cities had experienced a decline in benefits;(3)the evaluation scores at the element level of cities were uneven, and the difference of economically developed benefit expanded most obviously;(4)the obstacle level of economic development, economic continuity and social harmony had declined during the study period, while social development, environmental friendliness, and energy conservation and emission reduction had increased; the average fiscal revenue, the total retail sales of social consumer goods, the investment in fixed assets were the main obstacle factors.
