Impact of land-use change on ecosystem service values and their effects under different intervention scenarios in Fuzhou City, China

摘要

In this paper, substitution cost methods and prevention cost methods were used to estimate the influence of construction land on the ecosystem service value (ESV). Then, the total ESV was adjusted by the influence. The results showed that the ESV of Fuzhou City dropped from 105, 061.53 million Yuan in 1986 to 103, 916.53 million Yuan in 2006, mainly due to the degradation of cropland and water body and the increase of construction land. Water supply and waste treatment were the two largest ecosystem services, contributing approximately 35% of the total ecosystem service in both years. On the basis of land-use transition matrix, the compartment theory was applied to simulating landuse spatial pattern dynamics under different artificial intervention scenarios. The results showed that if we maintain or increase the existing intensity of interference, the total ESV of Fuzhou City will decrease by 58.13 million Yuan per year or 122.99 million Yuan per year, respectively; if we reduce the existing intensity of interference, the total ESV will increase by 52.38 million Yuan per year. In addition, the total ESV will decrease by 4.84 million Yuan for each 10% increase in the speed of the urbanisation process. We can conclude that the disordered expansion of construction lands and imbalance of ecological lands are main problems impeding the harmonious urban development. Given the similar social environment across the Chinese mainland, the findings from our study have important implications for the sustainable development of other rising cities in China and beyond.
