Land-Use/Land-Cover Change and Ecosystem Service Provision in Qinghai Province, China: From the Perspective of Five Ecological Function Zones

Qinghai Province is an important part of the Qinghai-Tibet Plateau and has special importance in construction ecological civilisation China, which related to security country long-term development. The land basis terrestrial ecosystem services. Land use/cover change (LUCC) can alter structure, distribution processes ecosystems, thereby affecting Ecological Function Zone (EFZ) zone designated by government protect ecosystems more effectively. Studying response services value (ESV) LUCC within EFZ great significance civilization Province. This study uses five periods use data from 1980 2020 selects equivalent factor method, correction method elasticity model analyse characteristics its impact on conclusions are as follows. (1) results showed that ESV decreased 822.559 billion yuan 819.903 2000, then increased rapidly 905.775 2020, showing a total increase 83.216 (1 RMB equates 0.144129 USD). restoration grassland expansion water bodies main reasons for growth ESV. (2) Sanjiangyuan was highest, followed Qaidam EFZ, Lake Qilian Mountains while Hehuang lowest. (3) generally declined all EFZs. Every 1% will result 4.78% ESV, (2.56%), (2.1%), (1.01%), with lowest index (0.53%). (4) high values gradually expands, clear spatial characteristic west low east. (5) most suitable area urban should avoid encroaching or polluting sources. provide reference optimising structure harmonising conservation development
