中文摘要：

供给服务价值是海洋生态系统服务价值的关键构成要素之一.选择食品供给（包括海水养殖和海洋捕捞）和原材料供给（包括浮游动物、鱼卵仔稚鱼、底栖生物资源）2个指标,采用市场价格法对温州海域生态系统提供的供给服务价值进行了评估,并运用Arc GIS的空间分析技术揭示了供给服务价值的空间分布规律.结果表明,2009年温州海域供给服务价值达201.36×10^8CNY,其中以原材料供给价值为主（79.72%）,食品供给价值所占比例较低（20.28%）.温州海域生态系统供给服务价值的分布与海域生态环境特征及海域使用现状密切相关,存在高度的空间变化,分布密度平均为26 695 CNY/hm2,高值区集中分布于南麂列岛滩涂和大渔湾附近浅海水域;中值区主要分布于洞头沿岸滩涂、乐清湾至苍南各县沿岸滩涂、苍南至洞头-5~-20 m等深线的海域;温州湾、苍南县及瑞安市-20~-30 m等深线的海域供给服务价值相对较低.

英文摘要：

The value of provisioning service is one of the key constituents of marine ecosystem services. This paper selected 2 indicators, food production and material production to estimate the monetary value of provisioning services from off shore ecosystem of Wenzhou. The market-price method was used to value food production and material production. GIS was applied to data processing, statistical analysis and compiling the spatial distribution map of provisioning services value of the ecosystem. The results show that in 2009 the total estimated value of provisioning services is 20. 136 billion CNY in Wenzhou sea areas. Comparatively, the material production makes a major contribution in value of 16. 053 billion CNY, about 79.72% of the total provisioning service in contrast to the food production which is lower in values of 4. 083 billion CNY. The present study demonstrates that the spatial distribution of the provisioning service in Wenzhou sea areas has extensive spatial variation, which is closely related to the characteristics of sea environment and the sea areas used. Thus, the average spatial density of provisioning services in Wenzhou sea areas is valued as high as 26 695 CNY/hm^2. The shallow sea areas in Dayu Bay and the intertidal zone of Nanji show higher density of provisioning services value. While the intertidal zone from Yueqing Bay to Cangnan county, the intertidal zone of Dongtou islands, the shallow sea areas within - 5 m and - 20 m depth contour from Cangnan county to Dongtou islands show medium density, and Wenzhou Bay and the shallow sea areas within -20 m and -30 m depth contour in Cangnan county and Ruian county are in lower density.
