摘要
为了量化厦门岛生态系统服务价值,为厦门岛合理实施城市发展规划、充分发挥自然生态系统服务功能、维护岛屿生态安全等提供科学依据,以福建省厦门岛为研究对象,采用Constanza及谢高地等提出的生态系统服务价值计算方法,在根据单位面积蓄积量对厦门岛各类型生态系统单位面积生态服务价值当量进行修正的基础上,对厦门岛生态系统服务价值进行评价,并从生态系统服务角度提出对策与建议。结果表明:厦门岛自然生态服务价值为35.29×104万元/年,单位面积生态服务价值为25.01万元/hm2,人均享有的生态服务价值为3991.63元/人;森林、湿地和绿地生态系统提供的生态服务价值分别为4.47×104万元、27.93×104万元和2.88×104万元,分别占总生态服务价值的12.67%、79.16%和8.17%;在9项生态服务功能中,气候调节、水文调节和废物处理提供的生态服务价值最大,合计为23.76×104万元,占总生态服务价值的67.34%。在厦门岛生态系统各项服务功能价值的贡献之中,其大小顺序依次为:废物处理>气候调节>水文调节>维护生物多样性>提供美学景观>气体调节>保持土壤>原材料生产>食物生产;与其他海岛及地区生态系统服务价值研究进行比较分析,结果显示生态系统服务价值的大小与城市经济发展水平有一定的关系,发展水平越高生态系统服务价值越高,但两者之间的关系并不呈正比。
The paper aims to quantify the value of ecosystem services in Xiamen Island,to provide a scientificbasis for the reasonable implementation of urban development plans,maximizing the natural ecosystemservices,maintenance of ecological safety island,etc.According to the method proposed by Costanza and XieGaodi et al,the author used the volume per unit area to adjust values per unit area of various ecosystemservices in Xiamen Island,in order to evaluate the ecosystem services value in Xiamen Island,and put forwardsome countermeasures and suggestions from the perspective of ecosystem services.The results revealed thatthe natural ecosystem services value was 35.29×10^8yuan/a,the ecosystem service value of one unit area was25.01×104yuan/hm2,per capita ecosystem services value was 3991.63 yuan.The value of ecosystem services offorest,wetland and green space system was 4.47 × 10^8yuan/a,27.93 × 10^8yuan/a and 2.88 × 10^8yuan/a,accounting for 12.67%,79.16% and 8.17% of the total value,respectively.It was estimated that among thenine ecosystem services,the maximum value of ecosystem services was provided by climate regulation,hydrology adjustment and waste disposal,which in total was 23.76×10^4yuan,accounting for 67.34% of thetotal value.Among the contribution of all ecosystem services value,the order was： waste treatment〉climate regulation〉hydrology adjustment〉provisioning of habitat〉provide aesthetic landscape〉gas regulation〉erosion control〉raw materials production〉food production.Compared with the ecosystem services value ofother islands and areas,the results showed that ecosystem services were associated with the level of urbaneconomic development,generally,the higher the level of urban economic development,the higher the value ofecosystem services,however,the relationship was not proportional.
