Changes in land use and ecosystem service values in Jinan, China

Changes in land use and ecosystem service values in the main urban area of Jinan between 1988 and 2002 were investigated in this paper using dataset deriving from LANDSAT TM images. In the study period, the most notable changes of land use are the decrease of cropland and the increase of construction land. With the urbanization, more and more lands were occupied for the construction purpose. Woodland and cropland are the dominant land use categories providing about 80% of the total ecosystem service value. Ecosystem service valuation results showed that the total ecosystem service value decreased by 42.86 million Yuan between 1988 and 2002, with an average annual decline of 3.06 million Yuan. Emphasis should be paid on the conservation of woodland and cropland in the future
