Abstract:

In the process of rapid urbanization, urban agglomeration development was promoting regional economic competition and cooperation, but also causing the intensification of contradictions between human and land, decline of ecosystem services level to a certain extent. In order to quantify the impact of urbanization on natural capital and reveal the influence mechanism of ecosystem service in human resource consumption process. In this study, Southern Fujian Urban Agglomeration (SFUA) is taken as an example, which is the typical rapidly urbanized area, emergy analysis method and GIS technology are used to analyze the spatial and temporal evolutions of renewable resources in the SFUA from 2000 to 2015, the evolution of eco-environment value and natural capital loss in the process of urbanization and land conversion. The results show that: (1) The renewable resources of SFUA presented a fluctuant decreasing trend in time, and gradually increasing trend in space; (2) The area proportion of urban land presented a significant increase trend in high environmental quality level, increased from 0 to 10.63%, the loss of regional eco-environment value caused by human activities was gradually rising; (3) Due to urbanization in the process of urban expansion, part of the natural land and agricultural land was converted to urban land, the total loss of natural capital caused by the conversion was 1.27E+22 seJ, and the currency value was more than 6.3 billion yuan. This study can help improve the research of eco-environmental effects due to urbanization, and provide decision-making reference for the urban agglomeration or regional eco-environment management and restoration.
