基于PSR模型的山东长岛海域海洋生物多样性研究
Marine Biodiversity Evaluation in the Changdao Sea, Shandong Province
摘要
Abstract
Marine biodiversity is critical to human survival and development and is important to many aspects of hu-man society. This study assessed the status of marine biodiversity in Changdao Sea, off-shore from Shandong Prov-ince, and analyzed the variation of biodiversity in Changdao County over a ten year period (2003-2013) to ex-plore the impact of human activity on marine biodiversity. Based on the Pressure-State-Response ( PSR) model, we constructed a marine biodiversity assessment index system, consisting of 14 indicators grouped as a pressure subsys-tem, a state subsystem and a response subsystem. The 14 indicators were selected according to the monitoring re-sults and data collected on the social economy, ecological environment, and environmental protection of Changdao County from 2003-2013 . The social-economic data was from the Yantai City Statistical Yearbook and Changdao County statistical bulletin for national economic and social development. The marine water quality data were ob-tained from monitoring data collected by the Eco-environment Monitoring Station of Changdao County. The index weighting for each of 14 indicators was determined using the Analytic Hierarchy Process ( AHP) . A five-level ma-rine biodiversity ranking scale and the corresponding criteria were proposed, based on foreign and domestic research on ecosystem assessment standards and the marine biodiversity index ( MBDI ) . The MBDI for Changdao County was calculated using the marine biodiversity assessment system and the marine biodiversity status was based on the MBDI score. The assessment results show that the marine biodiversity status of Changdao sea areas is good with a maximum MBDI value of 0. 766 in 2006 and the minimum value of 0. 60 in 2012, both in the good range. Biodiver-sity of Changdao sea areas is slightly stressed, but with high species richness. Ecosystem function is intact and could be able to recover from disturbance, if not severe, and good habitat quality benefits the Changdao Sea biota. Analysis of the indicators revealed the following trends:the state indicators, including sea water quality and protec-ted species were stable;the pressure indicators fluctuated, declining significantly from 2008 to 2011;the response indicators were generally steady, rising slightly from 2003 to 2013. Overall, the marine biodiversity of Changdao County is in good condition, owing to a stable marine biological community and the positive social response to the eco-environment.关键词
