- Abstract:

The characteristics of urbanization in the mountain cities are obviously different cities. With the rapid urbanization, the structures and patterns of land-use are bound to change dramatically, which will affect the further changes of the ecosystem service characteristics in urban area. We took Guiyang, which is a typical mountain city, as an example to clarify the rules of the changes of ecosystem services under the influence of urbanization within mountain city. We analyzed the terrain and socio-economic characteristics of gradient change of the value of mountain ecosystem services under the background of rapid urbanization in Guiyang with the help of ArcGIS. The research is based on the remote sensing data of the year 1995, 2005 and 2015 by using the value coefficient method of ecosystem services. The results show that the ecosystem services value decreased due to rapid urbanization in central and southern Guiyang; the supply service value was increasing in all terrain gradients, social and economic gradients; except the population density gradient, the trends of regulating service, supporting service, cultural service and total service value had changed from decrease to increase with the increase in terrain and social-economic gradients from 1995 to 2005 and from 2005 to 2015. Ecosystem service values showed the characteristics of fluctuation in the gradient of population density. The coupling effect of rapid urbanization and a series of ecological protection projects under the constraints of mountainous terrain is the significant factor that causes the value changing of the gradient characteristics of urban ecosystem in Guiyang City.
