伊宁市园林植物种类组成与物种多样性调查研究

Investigation on Species Composition and Species Diversity of Landscape Plants in Yining City

为系统掌握伊宁市园林植物的种类组成与物种多样性现状,通过实地踏勘及样地调查相结合的方法调查分析了园林植物的科属组成,类型组成,统计应用频率,计算多样性指数。结果显示,伊宁市现有园林植物共计238种,隶属于64科、137属,其中乔木104种、灌木46种、藤本植物5种、宿根花卉50种、一年生花卉31种、草类2种。调查样地内乔木、灌木、草本类植物中应用频率较高的植物分别为大叶白蜡、小叶白蜡,水蜡,紫茉莉、百日草、黑心菊,多数常用园林植物的应用频率不高。通过对调查样地植物多样性分析得出,伊宁市园林植物整体上具有较高的丰富度和多样性,其中乔木类植物的多样性程度、丰富度指数高于灌木类及草本类植物。调查结果为伊宁市城市园林绿化植物资源可持续利用提供了可靠的理论依据。

In order to grasp the species composition and species diversity of landscape plants in Yining City systematically, we investigated and analyzed the family and genus composition, type composition, application frequency and diversity index of landscape plants by field reconnaissance and sample plot survey method. Results showed that there were a total of 238 species of landscape plant, belonged to 64 families and 137 genera, contained 104 species of trees, 46 species of shrubs, 5 species of lianas, 50 species of perennial flowers, 31 species of annual flowers and 2 species of grasses. In the survey plot, the most frequently used trees were Fraxinus rhynchophylla, Fraxinus bungeana, shrubs were Ligustrum obtusifolium, herbaceous plants were Mirabilis jalapa, Zinnia elegans, and Rudbeckia hirta, but most common landscape plants were not used frequently. Through the analysis of the plant diversity in the survey plot, it was concluded that the landscape plants in Yining City had higher diversity and diversity on the whole, among which the diversity and richness index of arbor plants were higher than that of shrubs and herbaceous plants. The results provided a reliable theoretical basis for the sustainable utilization of plant resources in Yining City.
