- Abstract
Research on ecosystem services has a significant positive impact on ecosystem management, conservation, and the creation of ecological compensating systems. For the purpose to explore the characteristics of the geographical and temporal evolution and the driving forces behind the value of ecosystem services in Changsha, Hunan province, China, the four phases of land use data for the city from 2005 to 2020 were employed and analyzed by using geographic information systems and spatial statistics. The findings revealed that: (1) Forest land was the primary type of land used in Changsha. The area of construction land, wetland, and unused land increased, while the area of forest land, paddy field, dry land, and grassland decreased, and the area of water area was stable. (2) From 2005 to 2020, the value of ecosystem services showed a decreasing trend year by year. The forest land had the greatest impact on ecosystem service value (ESV) of all the land use types and the functions of hydrological regulation accounted for the largest share of the various ecosystem service functions. In terms of space, the high-value areas were mainly distributed in the east and west parts and rivers, while the low-value areas were mainly distributed in the middle which had the characteristics of positive agglomeration. (3) The results of the Geodetector revealed that spatial and temporal differences in ecosystem service values in Changsha were influenced by a combination of regional natural factors and socio-economic factors with a greater contribution from factors of Human Impact Index (HAI), Digital Elevation Model (DEM), and mean annual temperature. The interaction types were bivariate enhancement and nonlinear enhancement. The results of this study may serve as a scientific reference for the rational utilization of land resources and ecological environment protection in Changsha, Hunan, China.
