红树林生态系统健康评价指标体系的建立与应用

Study on the Establishment of Mangrove Ecosystem Health Evaluation Index System

热带森林生态系统在陆地生态系统中有着举足轻重的地位,它的健康状况直接影响生态稳定和经济社会的可持续发展。该研究以红树林生态系统的结构和功能作为切入点,运用活力、组织结构和恢复力作为评价指标,对海南东寨港红树林森林生态系统的健康状况进行实验性评估。结果表明:1.东寨港红树林森林生态系统的健康状况大多处于健康级和亚健康级,总体健康状况良好,健康、亚健康、中健康和不健康的面积比分别为60.12%、30.16%、8.62%和1.1%;2.该研究选取的指标体系及评价方法基本能够客观地描述东寨港红树林的健康状况,可为后续热带森林生态价值的评估体系研究提供参考。

Tropical forest ecosystem plays an important role in terrestrial ecosystem.Its health status has a direct impact on ecological stability and sustainable economic and social development.Taking the structure and function of the mangrove ecosystem as the entry point,the health status of the mangrove forest ecosystem in dongzhai port of hainan province was evaluated experimentally by using the vitality,organizational structure and recovery force as the evaluation indexes.The results showed that:1.The health status of the mangrove forest ecosystem in dongzhai port was mostly healthy and sub-healthy,and the overall health status was good.The area ratios of healthy,sub-healthy,medium healthy and unhealthy were 60.12%,30.16%,8.62%and 1.1%,respectively.2.The index system and evaluation method selected in this study can basically objectively describe the health status of the mangrove in dongzhai port,which can provide certain help for the follow-up research on the evaluation system of tropical forest ecological value.
