基于土地利用变化的东山岛滨海旅游区生态系统服务价值研究

Ecosystem Service Value in Coastal Tourist Area Based on Land Use Change on Dongshan Island

健康的生态系统是海岛型旅游区可持续发展的基础和先决条件。以滨海旅游的快速发展县——东山县滨海旅游区为案例,通过2005、2010和2015年3期土地利用数据,采用生态系统服务价值评估方法对研究区的生态系统服务价值进行测算并分析变化特征。结果表明:(1)2005-2015年,伴随着建设用地的显著增加以及园地、耕地和水域面积的减少,旅游区的生态系统服务价值共下降了552.74万元。(2)土地利用类型上,园地、耕地和水域的生态服务功能减少幅度较大,滩涂和未利用地在研究期内变化幅度较小。(3)生态系统服务类型上,其中调节服务功能价值下降绝对值最高,尤以气候调节和废物处理价值减少最显著,分别为147.44万元和122.29万元,供给服务中的原材料生产功能价值下降的绝对值最少,仅为17.95万元。

Healthy ecosystem services are the basic,prerequisites for the sustainable development on island.Taking Dongshan county whose coastal tourism flourishes rapidly as the case,this paper employed the method of ecosystem services valuation to calculate and analyze the ecosystem services value through the land use data in 2005,2010,and 2015.The results showed that:(1)from 2005 to2015,ecosystem services value have decreased by 5.527 million RMB due to the increase of construction land and the decrease of garden plot,cultivated land,and water;(2)for the land use types,the ecosystem services value in garden plot,cultivated land,and water have decreased dramatically.The ecosystem services of intertidal zone and unutilized land experienced a slight change;(3)for the types of ecosystem services,regulating ecosystem services had the highest increase,especially in climate regulation and waste disposal.The two regulating ecosystem services have decreased by 1.474 and 1.222 million RMB.Raw material production of provisioning ecosystem services had the slightest decrease,only by 0.180 million RMB.
