摘 要:海洋生态系统服务是人类从海洋生态系统中获得的效益,对沿海地区社会经济具有重要的支撑作用。采用国家标准《海洋生态资本评估技术导则》的方法,评估了江苏省管辖海域的生态系统服务价值,并揭示了其空间分布特征。江苏近海海域面积1.18万km2,2008年提供的生态系统服务总价值为426.02亿元,供给服务、文化服务、调节服务和支持服务价值分别为226.38亿元,186.61亿元,12.68亿元和0.34亿元;3个沿海地市比较,盐城近海生态系统服务价值最高,为184.55亿元;其次是连云港近海,为155.58亿元;南通近海最低,为85.89亿元。江苏近海生态系统服务价值空间分布密度平均为361.91万元/km2,从近岸到远海总体呈逐渐降低趋势,高值区主要分布在滨海旅游区和海洋保护区,中值区出现在养殖区,其它海域的服务价值则较低。江苏近海生态系统服务利用属于供给服务和文化服务共同主导的综合开发利用型,连云港近海属于文化服务主导的开发利用型,盐城近海属于供给服务和文化服务共同主导的综合开发利用型,南通近海则属于供给服务主导的开发利用型。建议在江苏近海开展离岸养殖工程,以提高近海供给服务价值;在盐城,特别是南通近岸海域开发海洋公园、渔家乐和其他亲水性旅游活动以提高文化服务价值。Marine ecosystem services represent the benefits people obtain from the marine ecosystem as a key support for socioeconomic development. The value, structure and spatial distribution of ecosystem services in Jiangsu coastal waters can provide important information for socioeconomic policy and planning. This paper evaluates the ecosystem services in Jiangsu coastal waters and tries to reveal their spatial distribution characteristics based on the national standards, "Technical Directives for Marine Ecological Capital Assessment". Ecosystem services indicators were selected based on the state of the environment and resources in Jiangsu coastal waters. Provision services in Jiangsu coastal waters include maricuhure, fishing and oxygen production. Regulating services include climate regulation and waste processing. Culture services include research and tourism. Supporting services include biodiversity and ecosystem diversity support. The spatial distribution of each ecosystem service was obtained using the Kriging interpolation method or "Vector to Raster" method. In 2008, the total ecosystem services value was 42.60 billion CNY in 11800 km2 coastal waters of Jiangsu. The value of provisioning services, cultural services, regulating services and supporting services was 22.64 billion CNY, 18.66 billion CNY, 1.27 billion CNY, and 0.034 billion CNY, respectively, accounting for 53.14%, 43.80%, 3.00%, and 0.08%, respectively, of the total value. Yancheng coastal waters had the highest marine ecosystem services value, Lianyungang had medium value and Nantong coastal waters held the lowest value. The spatial density of the ecosystem services value of Jiangsu coastal waters averaged 3.62 million CNY/km2, varying between 1.15--849.17 million CNY/km2. Lianyungang coastal waters had the highest spatial density of ecosystem services value, Yancheng had medium value, whilst Nantong coastal waters held the lowest spatial density. The spatial density of ecosystem services in coastal waters was mainly dominated by the provi
