湿地鸟类栖息地的植物群落修复与营建策略——以大理洱海湖滨缓冲带为例

Plant Community Restoration and Construction Strategy Based on Wetland Bird Habitats Creation—A Case Study of Ecological Restoration Project of Erhai Lakeside Buffer Zone,Dali

分析了湿地系统中植物群落构成与鸟类多样性之间的关系,并以大理洱海湖滨缓冲带为研究场地,对场地范围内鸟类资源及现状生境进行了分析,确定目标鸟类所偏好的生境条件,提出了以典型湖滨带垂直断面结构为基础进行生境划分,并从构建湖滨缓冲带生态廊道、增加不同生境内植物丰富度、提高植物异质性、增加生境面积及为鸟类营造远离干扰环境几个方面,对不同生境内的植被群落进行修复的具体方法,以期为合理设计鸟类的栖息环境以及保护湖滨缓冲带湿地生物多样性方面提供参考。

This paper analyzes the relationship between the composition of plant communities and bird diversity in wetland systems.The Erhai Lake Shore Buffer Zone in Dali is taken as a research site to analyze bird resources and current habitats within the scope of the site.The preferred habitat conditions for target birds are determined.A habitat division based on the vertical cross-section structure of the typical lakeside zone is proposed.Specific methods were proposed to restore the vegetation communities in different habitats from the following aspects:constructing ecological corridors of the lakeside buffer zone,increasing plant richness in different habitats,improving plant heterogeneity,increasing habitat area and keeping birds away from disturbance in order to provide reference for the rational design of bird habitat environment and protection of wetland biodiversity in lakeside buffer zone.
