摘要:
依据“压力状态响应”(PSR)概念模型,构建了兴化湾海湾生态系统退化评价的指标体系,并采用综合指数法和模糊评价法对该海湾生态系统的退化程度进行了定量评价.结果表明:自2005年兴化湾海湾生态系统呈现出退化的趋势,到2008年生态系统处于“中度退化”状态;兴化湾海湾生态系统受到的环境胁迫作用较大,尤其从2005年以来生态系统面临的压力有所增大.导致兴化湾海湾生态系统退化的主要胁迫因子有富营养化、围填海、GDP增长对环境的压力、滨海电厂温排水以及海洋捕捞等;在持续较大的压力下海湾生态系统的状态表现出恶化趋势.
Abstract:
Based on the "PressureStateResponse"(PSR) concept model,an ecosystem degradation assessment index system was established for Xinghua Bay,organising 29 indicators into pressure,state,response indicators.The degree of the ecosystem degradation was evaluated by using the comprehensive index method and the fuzzy synthetic evaluation method.The results showed that Xinghua Bay ecosystem had a trend of degradation from 2005 to 2008 mainly due to the increasing environmental pressure,and the ecosystem was moderately degradated in 2008.Eutrophication,coastal reclamation,GDP growth,cooling water discharged from coastal power plants and marine fishing were the main stress factors which caused the degradation.The state of Xinghua Bay ecosystem had shown a degradating tendency under continuous and enormous pressures.It is mainly reflected by the biodiversity indicators,of which the values all decreased from 2005 to 2008.The response indicators had increased from 2005 to 2008,which could be considered that the government interventions had played an important role in reducing the ecological and environmental pressures.
