Abstract

Abstract: Aiming at the problem how to change the ecosystem service values (ESVs) in Yunnan-Kweichow Plateau after the ecological restoration project was carried out, based on equivalent factors and spatial autocorrelation analysis methods to study the spatio-temporal characteristics of ESVs in the Yunnan-Kweichow Plateau in this paper. The results show that: ①The conversion of land use types is mainly the conversion of cultivated land to construction and water. ②After the ecological restoration projects, the ecosystem has been improved, ESVs first decreased and then increased in 38 years, with a cumulative increase of 9.491 billion yuan. The ecological adjustment capacity of forests and the total value generated are more than 218 billion yuan, and the least is desert, which is about 10million yuan. ③The spatial distribution pattern of ESVs is higher in the southwest and lower in the middle. ④ESVs from 1980 to 2018 showed a significant positive spatial correlation, and the Moran index was greater than 0.46, showing obvious clustering characteristics.

Key words: land use, ESVs, equivalent factor, Yunnan-Kweichow Plateau, spatio-temporal analysis
