【摘要】:生态系统服务价值研究是目前生态学研究的热点之一,海岛生态系统的特殊性令其更易受人类活动和环境变化的影响。文章在海岛生态系统服务价值当量修订的基础上,对典型海岛金塘岛1986—2014年的生态系统服务价值进行评估,分析了金塘岛近30年来生态系统服务价值的时空动态变化。结果表明:城镇生态系统面积持续增加,其他生态系统类型面积不同程度减少,减少的生态系统类型大多数转化为城镇。1986—2014年金塘岛的生态系统服务总价值呈下降趋势,共减少了1.08亿元,减少了30.23%,其中湿地与森林的生态系统服务价值量减少最多,城镇的价值变化率最大。空间上表现为价值极低区域沿着人类活动方向呈现急剧扩大趋势。生态系统提供的产品与服务在数量和质量上逐步下降,不利于海岛的可持续发展。该研究为海岛地区生态系统服务价值当量修订提供参考,同时对转变海岛经济发展方式,促进海岛可持续发展提供基础信息与决策依据。
[Abstract]:The study of ecosystem service value is one of the hotspots in ecological research at present. The particularity of island ecosystem makes it more vulnerable to the influence of human activities and environmental changes. Based on the revision of service value equivalent of island ecosystem, this paper evaluates the ecosystem service value of Jintang Island from 1986 to 2014, and analyzes the temporal and spatial dynamic changes of ecosystem service value in Jintang Island in the past 30 years. The results showed that the area of urban ecosystem continued to increase and the area of other ecosystem types decreased to varying degrees. Most of the reduced ecosystem types were converted into the total value of ecosystem services of Jintang Island from 1986 to 2014. The value of ecosystem services of wetland and forest decreased the most, and the value of urban value changed the most. In space, the extremely low value region shows a trend of rapid expansion along the direction of human activities. The quantity and quality of the products and services provided by the ecosystem are decreasing gradually, which is not conducive to the sustainable development of the islands. The study provides a reference for the revision of the ecosystem service value equivalent in the island area, and provides the basic information and decision basis for the transformation of the island economic development mode and the promotion of the island sustainable development.
