/目前，重点是恢复美国西部的河岸植被。决定恢复什么和在哪里需要了解河岸植物群落与其环境之间的关系，以及建立恢复的目标或参考条件。利用非现场数据和历史分析等方法建立了恢复参考条件。本文从多变量聚类分析的结果出发，提出了解释参考群落组成和结构的准则。该方法用加利福尼亚内华达山脉、中央山谷和南部沿海地区的河流数据来说明，以获得河流到达和洪泛区地形的参考群落的描述。聚类分析结果可用于量化河漫滩内退化群落和参考群落的面积，从而促进恢复成本估算。关键词：河岸植被；流域规划;河岸恢复;集群analysishttp: / / link.springer-ny.com/link/service/journals/00267/bibs/24n1p55.html
/ Currently, there is an emphasis on restoration of riparian vegetation in the western United States. Deciding on what and where to restore requires an understanding of relationships between riparian plant communities and their environments along with establishment of targets, or reference conditions, for restoration. Several methods, including off-site data and historical analysis have been used for establishing restoration reference conditions. In this paper, criteria are proposed for interpreting reference community composition and structure from the results of multivariate cluster analysis. The approach is illustrated with data from streams in the California Sierra Nevada, Central Valley, and southern coastal region to derive descriptions of reference communities for stream reaches and floodplain landforms. Cluster analysis results can be used to quantify the areas of both degraded and reference communities within a floodplain, thereby facilitating restoration cost estimation.KEY WORDS: Riparian vegetation; Watershed planning; Riparian restoration; Cluster analysishttp://link.springer-ny.com/link/service/journals/00267/bibs/24n1p55.html
