Abstract
Ecological management based on the ecosystem approach promotes ecological protection and the sustainable use of natural resources. We developed a quantitative approach to identify the ecological function zones at the country-scale, through integrating supply and demand of ecosystem services. We selected the biologically diverse hotspot of Baoxing County, which forms a part of the Sichuan Giant Panda World Heritage Site, to explore the integration of ecosystem services supply and demand for ecosystem management. Specifically, we assessed the various support, provision, regulating, and cultural services as classified by the Millennium Ecosystem Assessment. We applied the InVEST (Integrated Valuation of Ecosystem Services and Trade-offs) model to spatially map habitat quality, water retention, and carbon sinks, and used statistical data to evaluate food products, animal husbandry, and product supply services. We then quantified the demands for these services in terms of population, protected species, hydropower, water, and land use. The relationship between areas of supply and areas of demand was discussed for each township, and the spatial variability in the supply–demand relationship was also considered. As a result, we spatially divided the county into six ecological functional areas, and the linkages between each region were comprehensively discussed. This study thus provides a detailed methodology for the successful implementation of an ecosystem management framework on a county-scale based on the spatial partitioning of supply and demand.
Highlights
Ecosystem management based on the ecosystem approach considers the system’s integrity for the effective protection of both biodiversity and ecosystem services
Ecological function zoning is the basis for carrying out ecosystem management
We propose a zoning method based on the relationship between supply and demand of ecosystem services which can effectively identify the spatial differences in the protection of ecological functions in counties and contribute to sustainable development planning
Summary
Ecosystem management based on the ecosystem approach considers the system’s integrity for the effective protection of both biodiversity and ecosystem services. The core concept of ecosystem management is consideration of the natural, social, and economic aspects of a region as a whole, with the aim of maintaining ecosystem health and promoting the sustainable use of ecosystem services [1]. Ecosystem management involves the sustainable management of human activities to maintain ecological balance and improve human welfare, and its success lies in establishing effective methods for integrating ecosystem services and human needs. This is an adaptive management approach, which contributes to minimizing the loss of ecosystem services as a result of globalization [3]
