摘要
以武汉市为例,利用从1996年和2001年TM数据中获取的景观数据,估算了武汉市生态服务价值并分析了景观之间的转化所引起的生态服务价值的变化。结果表明:各景观类型中水域景观的生态服务价值贡献系数最大,达到2.869;研究区域生态服务价值总量变化不大,2001年比1996年只下降了3688.79万元,但各景观生态服务价值变动很大,其中库塘生态服务价值增加了2.38亿元,河流的生态服务价值减少了2.33亿元,其变化率分别达到40.74%和-9.16%;由于河湖被占用所造成的生态服务价值损失达到9891.68万元,城市建设占用其它景观类型所带来的生态服务价值损失达到9908.37万元,这说明建设用地的发展对其他自然景观占用已经影响到了武汉市生态系统服务功能发挥。
Based on the data of land-use/land cover change produced from the integrating Landsat TM images of Wuhan city in 1996 and 2001, the dynamics of the ecosystem services value was evaluated. The results showed that water landscape was very important to the ecological system in Wuhan city and its contribution coefficient to the total ecological services value was 2.869. The total ecological services value was only decreased by 3 688.79x 104 RMB Yuan from 1996 to 2001, but ecological services values of each landscape changed greatly. As compared with other landscape types, the ecological services values of the pond and river -lake changed most greatly, and the ecological services value of pond landscape was increased by 2.38×10^8 RMB Yuan and the ecological services value of river-lake landscape was decreased by 2.33×10^8 RMB Yuan. The loss of ecosystem services value for the land cover of rivers and lakes transferring into other land-use types is 9 891.68×10^4 RMB Yuan, and the loss of ecosystem services value for constructed land occupying other land-use types is 9 908.37×10^4 RMB Yuan.
