Valuation of ecosystem services in Jiangsu coastal waters

Abstract

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 mariculture, 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冶 method. In 2008, the total ecosystem services value was 42. 60 billion CNY in 11800 km 2 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
