基于植物区系分析的雾灵山自然保护区种子植物解说对象研究

摘要

植物资源是自然保护区景观生态非常重要的组成部分.以雾灵山自然保护区种子植物作为研究对象,通过各科物种数排序,筛选出居前30位科作为优势科,分析其物种数分布、分布型、单属科植物种数量分布特征；对优势科所属物种数从大到小排序,将前50位的属作为优势属,分析优势属的物种多样性特征；基于重点植物解说原则,筛选出雾灵山植物重点解说对象.%Plant resources are important compositive parts of ecological landscape in nature reserve. Taking the seed plants growing in Wulingshan Resever in Xinlong county, Hebei province as studying objects, through ordering the nunber of species in each family, the first 30th dominant families were filtered out as the predominant familzes, and the characters of structure, distributions and quantity of the flora in Wulingshan Resever were analyzed. The first 50th dominant genera were elected as the predominant genera and the diversity characters of the dominant genera were analyzed. Based on the interpretative principles, the important interpretative objects of plants in Wulingshan Nature Researve were chosen.
