海南东寨港、三亚河和青梅港红树林群落健康评价
Health evaluation of mangrove community in Dongzhaigang, Sanyahe, and Qingmeigang Mangrove Nature Reserves of Hainan province
【摘要】 以海南东寨港、三亚河和青梅港红树林保护区为研究对象,构建出红树林健康指数(EI)评价指标体系和方法,并确定了评价标准和评价等级,对海南红树林群落进行了健康状况评价。结果表明,2009年,东寨港、三亚河和青梅港保护区的红树林群落健康指数分别是0.8640,0.4798和0.5791,分别处于Ⅰ级(健康)、Ⅲ级(亚健康)和Ⅱ级(中等健康状态)。结果说明东寨港红树林群落结构和功能稳定,生态演替序列完整,对环境压力响应良好。三亚河和青梅港红树林处于城市中心区和旅游开发区,受外界干扰影响大,退化明显,红树林的保护和恢复受到不同程度的限制。
【Abstract】 An evaluation index system and method are built for mangrove health in Hainan province’s Dongzhaigang,Sanyahe,and Qingmeigang reserves.Evaluation criteria and rating are also set up to look into the health conditions of the mangrove community.The results show the health indices of the mangrove community in the above-mentioned three areas are 0.8640,0.4798,and 0.5791,which fall into the ranks of Ⅰ-grade(healthy),Ⅲ-grade(sub-healthy),and Ⅱ-grade(moderate healthy),respectively.Such results represent the mangrove community structure and functions of the Dongzhaigang are in stable condi-tion,its ecological succession sequence is intact,and the community responds well to environmental pressure.Located in downtown area and tourism development zone respectively,the mangrove in Sanyahe and Qingmeigang are heavily affected by environmental disturbances,which led to their obvious deterioration.The protection and recovery of the two areas are lim-ited in different degrees.
