Comparative Study on the Diversity of Macrobenthos in Typical Mangrove Regions of Dongzhai Harbor , Hainan Island
This paper researched the environmental changes in mangrove regions, as well as the relationship between different mangrove communities and macrobenthos diversity to provided a scientific basis for mangrove wetland protection and sustainable use. Mechanical sampling method was used to select sampling points, and qualitative and quantitative survey for macrobenthos resources in mangrove regions in Peigang and Sanjiang of Dongzhai harbor. Using the diversity index, richness, evenness, the diversity of benthic fauna was analyzed. The effects on macrobenthos diversity from the different communities of the mangrove were also analyzed. The number and composition of the macrobenthos in mangrove region in Peigang was very different from that in Sanjiang. The average biomass and diversity of macrobenthos in mangrove region in Peigang was 608.69 g·m~(-2) and 1.157 1 respectively, Benthic habitat density was 683.33 m~(-2), that in Sanjiang was 214.60 g·m~(-2) and 1.037 2, Benthic habitat density was 547.00 m~(-2). The diversity of macrobenthos in mangrove region in Peigang was higher than that in Sanjiang. The difference in quality of soil environment and plant height of mangroves, Yu shelter, the forest ecosystem, such as light and ventilation in different mangrove communities caused differences in the characteristics of the diversity of macrobenthos.
