Effects of Ecotourism Development on Ecosystem Service Value of Hani Terraces Fields from 2005 to 2020
Hani terraced fields is a unique agricultural and cultural landscape in the mountainous ar-eas of southwestern China,which was selected as a World Heritage Site in 2013.With the develop-ment of ecotourism and measures to convert farmland to forests,the land use types and landscape patterns of Hani terraced fields have a significant change,and make an impact on the value of eco-system services.We selected two typical villages in the core area of Hani Terraced Fields World Cultural Heritage as the research objects,and studied the changes in land use types,landscape pat-terns,and ecosystem service values from 2005 to 2020.It shows that:(1)there are significant changes in land use,with a rapid increase in forest land and urban construction land,and a de-crease in grassland and arable land area;(2)the degree of landscape fragmentation decreases,land-scape connectivity increases,and is dominated by advantageous patches;(3)the ecosystem service value has significantly increased,with a significant increase in the ecosystem service value of forest land and water bodies,while farmland and grassland have decreased;except for food production,the value of other ecosystem services has increased to varying degrees;(4)the overall value of eco-system services in the research area is higher in the south and lower in the north,and the ecosystem service value in the southwest,northwest,and southeast regions has significantly increased;(5)the ecosystem service value is most sensitive to forest land and least sensitive to water bodies,and forest land has the greatest contribution to the ecosystem service value.It suggests that reasonable ecotour-ism development and protection policies can improve the landscape pattern of Hani terraced fields and enhance their ecosystem service value.
