湿地生物多样性评价体系研究

湿地是自然界物种最丰富多样的生态系统之一,对其生物多样性的评价方法及保护的研究具有重要意义.在有关湿地资源评价理论的基础上,针对我国湿地的特征与现状,确定了物种多度、物种相对丰度、稀有物种、群系多度、湿地类型、保护地类型、外来物种入侵、植被破坏程度以及保护意识和管理水平等9项指标,建立了湿地生物多样性评价体系,并为各项指标确定了科学、准确的评分标准及权重,可为今后我国湿地生物多样性的评价、保护、恢复等工作的开展提供可靠依据.

Study on evaluation system of wetland biodiversity

Wetland is one of the ecological systems including the most abundant species, and it is significant for the assessment of biodiversity and protection research on wetland. Based on wetland resources evaluation theory, aiming at the characteristics and current situation of wetland in our country, this paper determined 9 indicators including the species abundance, species relative abundance, rare species, formation degrees, wetland type, protection land type, invasive species, vegetation damage, protection consciousness and management level, established wetland biodiversity evaluation system, also determined the scientific and accurate grading standard and weight. The results can provide reliable basis for the future evaluation, protection and restoration of wetland biodiversity in China.
