Abstract
Urban expansion has been proved to spur significant changes in economic development worldwide, yet it degrades ecosystem services. Seldom attempts are made to explore the dynamic relationship between economic benefits and ecosystem services. As such, we simulated land use in Wuhan, the capital city of Hubei Province in China, by employing the LANDSCAPE model (LAND System Cellular Automata model for Potential Effects) in scenarios with datasets supported. This paper analyzes the amount of variation of urban growth between its corresponding implications for ecosystem services in Wuhan, and further reveals a meaningful dynamic linkage between economic benefits (EB) and ecosystem services value (ESV). The amount of urban expansion is a critical factor affecting tradeoffs of EB and ESV. A certain amount of urban expansion (the turning point) will worsen tradeoffs between EB and ESV, and when the amount of urban growth surpasses the turning point, a small increase of EB will pay a great amount of ESV. The better the amount of urban growth is controlled, the more harmonious the EB and ESV will be. Our research is helpful to find the turning point as well as the proper amount of urban growth at the aspect of tradeoffs between EB and ESV.
Highlights
Natural ecosystem is vital in human survival, livelihood and wellbeing directly and indirectly [1], it affords all resources for fitness, progress and sustainability of the whole human society [2,3], and it suffers
This paper focuses on dynamics of tradeoffs between ecosystem services and economic benefits by simulating land use changes driven by urban expansion for the city of Wuhan
Cropland will be preempted in the early stage of the simulated urban expansion process; amount of wetland will be occupied under the combined pressure of urban expansion and basic farmland protection in the very process
Summary
Natural ecosystem is vital in human survival, livelihood and wellbeing directly and indirectly [1], it affords all resources for fitness, progress and sustainability of the whole human society [2,3], and it suffers. Land use changes are the most important factors of global change, and do change the landscape of the earth’s surface, and have important influence on water purification, soil conservation, nutrient cycles, regional climate [9], biodiversity [10,11], has seriously damaged ecosystem services [12], introduced habitat fragmentation [13] and isolation, and has affected the development of human society [14]. The latest vivid example should be urban waterlogging disaster in Wuhan in the summer of 2016 These reflect a series of conflicts between ecosystem services and economic benefits. China’s economic development benefits from urban expansion, but the obvious enclosed negative impact of urban expansion on ecosystem structure and function makes the whole ecosystem service vulnerable, in result obstructs economic progress [22]. Making a sustainable land use planning in consideration of economic development and ecosystem services become an important and urgent task for sustainable development
