Abstract

Abstract: Taking Yunnan Province as the research area, the ecological protection and restoration zoning work at the county level was carried out by quantifying ecosystem service （ES） supply and demand and mapping the matching relationship between the two. The results showed that obvious spatial heterogeneity was seen in both ES supply and demand, and these two showed a complementary relationship spatially. The forest areas in the northwest and southwest Yunnan were high supply areas, while the eastern parts were low supply and high demand areas. The Yunnan Province was divided into four regions according to the characteristics of supply and demand： coordination type （high supply-high demand）, which should focus on improving the supply level of other ecological land except water areas; urban and rural remodeling type （low supply-high demand）, which should pay more attention to the spatial allocation and coverage of urban green space; key restoration type （low supply-low demand）, which should carry out soil and water conservation, mine rehabilitation and other rehabilitation projects in local areas; ecological conservation type （high supply- low demand）, which should take ecological conservation as the main goal to achieve the overall improvement of forest quality.

Key words: ecosystem service supply, ecosystem service demand, ecological protection and restoration, zoning, Yunnan Province
