本文应用Costanza生态系统服务价值计算公式,参照中国陆地生态系统单位面积生态服务价值当量表,对1990～2007年醴陵市土地利用的变化进行了分析并计算了相应的生态系统服务价值及其变化.结果表明:①1990～2007年间,醴陵市生态用地的减少导致生态系统服务价值由1990年的50.81亿元下降到2007年的50.59亿元,下降了0.43%;②在土地利用过程中,偏重其生产功能而忽视了生态功能,使生态功能负荷过重;③1990～2007年间,醴陵市的人均国内生产总值增长了11倍,但人均生态福利却下降了16.8%,生态福利减少过快.

The objective of this paper was to analyze the temporal changes of land use and to examine their effects on the changes of ecosystem services value （ESV）. The methods were based on ESV computing formula and ESV coefficients. The results showed： （1）During 1990 to 2007, the ecosystem service value reduced from 50.81 × 10^8Yuan to 50.59×10^8 Yuan, a decline of 0.43%, due to reducing of land for ecology. （2）In the process of land-use, the production function of ecosystem was overweight and the ecological functions were neglected, which led...
