摘要
分析盐城海滨湿地的主要生态环境问题,筛选自然灾害,综合污染,互花米草作为主要风险源,以盐城海滨湿地保护的目标种丹顶鹤和其他珍稀鸟类及生境作为评价受体进行研究,以物种重要性指数、生物多样性指数和自然度指数计算生态指数;依据生态指数和生态脆弱度指数来计算生态损失度指数;最后以生态损失度指数,自然灾害指数,综合污染指数,互花米草入侵指数来构建盐城海滨湿地生态风险评价的指标体系,并进行盐城海滨湿地的生态风险评价。
In this paper,the major ecological environment problems in the coastal wetland of Yancheng were analyzed in details.The study is based on choosing natural calamities,comprehensive pollution and Spartina alterniflora as main risk sources,red-crowned crane,other rare birds and habitat as the appraise receptor.The calculations of the ecological index with importance index of the species,bio-diversity and naturalness index,and the ecological loss index degree according to the ecological and fragile index degree of ecology were done.Then,the general system of the regional ecological risk assessment in the coastal wetland by synthesizing the ecological loss,natural calamity,comprehensive pollution and the Spartina alterniflora invading index and evaluation on the ecological risk of the coastal wetland of Yancheng were made.
