- Abstract:
-
Based on the status of Guangxi land use data in 2000, 2005 and GIS platforms, comprehensively utilizing ArcGIS 10.1, CLUE-S model and SPSS 19.0 software et al, and combining with equivalent value per unit area of ecosystem services in China by Xie Gaodi et al, this paper calculated and amended the values of ecosystem services and the spatial distribution of ecosystem service value table in Guangxi, and revealed Guangxi karst mountainous area’s ecosystem service value temporal variation by comparing with those situations in 1995, 2000 and 2005. Finally, it was found that the main types constituting of land area the value of ecosystem services were farmland, forest land, grassland; if the human impact of change between 2001 and 2005 was been kept, the value of ecosystem services in Guangxi Karst Mountainous Area will be basically stable in 2015, will reach to 66.439 billion (RMB); from the perspective of space,the high value areas for values of ecosystem services have a tendency to expand, low value areas are still expanding, and the middle value areas will narrow, particularly in the southwest, northeast should be alerted because of the construction land expansion and radiation effect, thus the eco-environmental situation is still very grim.
