Abstract:

The city of Ordos is in the central part of the ecotone between agriculture and animal husbandry in northern China, and the rapid economic development brings great pressure to the ecological environment. Ecosystem services and their inter-related changes in Ordos have great significance for the sustainable development of ecosystems in this semi-arid area. This study calculated the four key ecosystem services of food supply, carbon storage, water production, and soil conservation in Ordos in 2000 and 2010, and used the relevant analysis to explore the tradeoffs and synergies between the four services at the 30 m × 30 m grid scale and introduced the rose map. The relationship between the ecosystem services of different land-use types was analyzed. The results show that there is a synergistic relationship between water production and soil conservation, a synergistic relationship between food supply and soil conservation, a tradeoff relationship between soil conservation and food supply, and a tradeoff relationship between food supply and carbon storage. The eastern agricultural area of Ordos contains most of the hotspots of multiple ecosystem services. The production of water reduced as soil conservation and carbon storage improved in cultivated land and woodland, while in the grassland the four ecosystem services increased simultaneously.

Key words: ecosystem services, tradeoffs and synergies, hotspots, Ordos City
