- Abstract:
-
The evaluation of land use benefit is of great significance to promote the intensive use of land resources and ultimately realize the sustainable development of the region. We took 26 prefecture-level cities in the Yangtze River Delta urban agglomeration as the research samples,used the coefficient of variation method to measure the weights of 15 indicators such as per capita gross national product,and then used the TOPSIS method to determine the relative proximity of each benefit,and explored spatiotemporal changes of land use benefits before and after after 2012. The results show that:(1)the weight index of each land use benefit in the Yangtze River Delta urban agglomeration follows the order of economic benefit>ecological benefit>social benefit; economic benefit is the aspect that has the greatest impact on the comprehensive benefits of land use.(2)the comprehensive land benefits of the Yangtze River Delta urban agglomerations are low and the land use benefits of cities at different levels differ significantly;(3)from the perspective of different provinces,Shanghai's economic,social,and comprehensive benefits are far ahead,while Anhui Province's comprehensive land benefits are low; from the perspective of different city levels,the higher the city level scale,the higher the land economic and comprehensive benefits,but the ecological benefits lower:(4)after 2012 of the Communist Party of China,except for the ecological benefits,the land use benefits showed a continuous improvement trend. The spatial distribution of comprehensive benefits showed the characteristics of ‘high in the east and low in the west,high in the south and low in the north'. The gap is gradually narrowing. Finally,it is proposed to strengthen cooperation between the four provinces and 26 prefecture-level cities,and the government should introduce the reasonable policies and measures.
