红树林湿地健康评价指标体系

根据红树林湿地健康的内涵及红树林湿地特征,分析红树林湿地结构与功能的关系,阐明影响红树林湿地健康的要素,确定健康评价指标选取的原则。在此基础上应用层次分析法(Analytical Hierarchy Process),构建红树林湿地健康评价指标体系。健康评价指标体系由目标层、要素层、要素亚层和指标层4个层组成,其中要素层包括植物群落结构、生物安全性、生境的完整性与稳定性、生境理化性质、生物因子指标5个方面,指标层包括物种组成、物种丰度、建群种比例郁闭度、龄组结构、更新等级等41个指标。

An Indicators System for Health Assessment of Mangrove Wetland

According to the meaning of mangrove wetland health and characteristics of mangrove wetland, the relationship between structure and function of mangrove wetland was analyzed, the elements that impact mangrove wetland health were identified, and the principles selected for the health assessment were determined. The Analytical Hierarchy Process (AHP) was used to establish mangrove wetland health assessment indicators system. The indicators system was composed of 4 levels, i.e. target level, element level, element sub-level and indicators level. Among them the element level contains 5 aspects of structure of plant community, physical and chemical properties of the habitat, the integrity and stability of the habitat, biosafety and biological factors. The indictor level contains 41 indicators such as species composition, species abundance, canopy density and etc.
