摘要
从湿地植物的科属和区系特征以及生活型和生态型的角度,研究了五台山风景区人为干扰下不同群落类型区植物种的生态特性。结果表明,①人为干扰强烈的区域,其植物属数和种数明显小于人为干扰少的区域;豆科(Leguminosae)、唇形科(Lamiaceae)、菊科(Asteraceae)、蓼科(Polygonaceae)和禾本科(Poaceae)植物种类出现的频率最高,属于忍耐性的植物种类;单型科、单型属和单型种出现的频率也较高。②就物种的区系对人为干扰的生态响应而言,温带成分具有广泛分布的态势,而世界分布和热带分布的植物种类贫乏。随着人为干扰程度的加剧,物种区系成分趋于单一。③除牡蒿群落(Comm.Artemisia japonica)区外,随着人为干扰程度的加剧,一年生植物的比例在明显增加,地上芽植物的比例在明显减少。④随着人为干扰程度的加剧,湿生植物的比例不断增加,而旱生植物、中旱生植物、旱中生植物和中生植物的比例都呈减少趋势。
The species characteristics in the different communities of wetland plant with human disturbance were studied from their families, genera, life-form and ecology-form in Wutai Mountains. The results showed that the number of genera and species was much less in the area with serious disturbance than that with little disturbance. The appearing frequency of species in the families of Leguminosae, Labiatae, Compositae, Polyg- onaceae and Poaceae was the most, and they belonged to the endurance species. Moreover, single family, gen- era and species often appear. As of the ecological response for species flora to humban disturbance, the compo- nent in the temperate zone distributed widely, however, those in the entire world and the tropical zone were poor. The flora trended to be single with the increasing disturbance. Except for area covered by Comm. Arte- misia japonica, as human disturbance was increasing, the proportion of chamaephytes was decreasing gradual- ly, and that of therophytes was increasing. With the disturbance increasing, the proportion of hygrophytes was increasing gradually, and those of xerophytes, middle-xerophytes, xero-middlephytes and mesophytes trended to decrease.
