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.
