摘要
应用Costanza生态系统服务价值计算公式和谢高地等人的中国陆地生态系统单位面积生态服务价值表,研究了醴陵市1996—2005年土地利用变化对生态系统服务价值的影响。结果表明,土地利用变化主要体现为耕地、水域的减少和林地、建设用地的增加。价值系数的差异造成土地利用变化产生的生态系统服务价值相互抵消,但醴陵市生态系统服务价值仍减少了3562万元,应引起相关部门的足够重视。
Effects of landuse change on ecosystem service value in Liling County from 1996 to 2005 were stud- ied by using the table of China land ecosystem service values of unit area, ESV computing formula, and ESV coefficients. Results showed that the waters area, as well as the increase landuse change is mainly reflected by the decrease of cultivated land and of woodland and construction land. Although the value of ecosystem services arising from landuse change caused by the value of the coefficient differences is offset each other, the value of ecosystem services in the city is reduced 35 620 000 yuan, which deserves our great attention.
