摘要
山东湿地共分布有湿地高等维管植物70科277种、苔藓植物12科24种,在植物种类组成上以莎草科和禾本科植物等最为丰富。植被类型有灌丛、灌草丛、草甸、盐生、沙生、沼生和水生植被等7种。湿地植被的分布既受地理位置、气候、海拔等影响,又受制于水分、土壤和土壤含盐量等因素。湿地演替是植物群落的演替过程,即随着湿地的发育,特别是土壤水分和营养的变化,导致植物种类和群落发生改变的过程。湿地植物群落演替是气候、水文以及地貌、土壤等自然要素综合作用的结果,客观反映了湿地的形成、发育与演替过程。
There are 277 species of 70 families of vascular plants, 24 species of 12 families of lichens occurring in wetlands in Shandong province. Sedge grasses and gramineous plants constitute the majority of the species composition. The wetland vegetations can be categorized into 7 groups of shrubs, shrub-like grasses, meadows, salinity plants, desert plants, swamp plants, and aquatic plants. The distribution of wetland vegetation is affected not only by geographical location, climate and altitude, but also by water, soil and soil salinity. Wetland succession can be seen as the succession of plant communities, i.e. the process of changes in species composition and in plant communities caused by the development of wetland, especially the changes in soil moisture and nutrition. Succession of wetland plant community is the consequence of integrated effects by a number of natural elements such as climate, hydrology and topography and soil. It objectively reflects the formation, development and succession of wetland.
