- Abstract:
-
In order to analyze land use change and its impact on ecosystem service value(ESV)in Wuhan, remote sensing images from 1990 to 2015 were used to reveal land use change patterns and their influence on ESV through the methods of land use dynamic attitude, land use transfer matrix, ecosystem service value and ecological contribution rate. The results showed that the land use structure of Wuhan had changed significantly, the cultivated land, forest land and unused land had decreased, and the construction land and water area had increased; the major land use shifts in Wuhan occurred from arable land to construction land; the comprehensive dynamic attitude of land use in Wuhan was far higher than that of the whole country, the dynamic attitude of construction land was much higher than those of other land types, and the urbanization construction was on the increasing speed; total ESV in Wuhan increased, and ESVs of water area and grassland increased, while ESVs of cultivated land, forestland and unused land decreased; the value of ecosystem service was dominated by hydrological regulation and water supply, and the biggest change of single ESV was hydrological regulation; the total ecological contribution rate of water area, cultivated land and forest land to ESV was greater than 98%, which was the main contributor of ESV and the sensitive factor on ESV change.
