摘要
植被稳定性是植物群落结构与功能的一个综合特征 .从稳定性研究的意义、概念、维持机制以及研究方法方面对植被稳定性研究进行了综述 ,主要从多样性理论、冗余理论方面探讨了稳定性的维持机制 .在稳定性的研究方法中 ,指出应加强对草地生态系统的稳定性研究 ,主要是对天然草地的研究 ,另外从植被结构与功能方面对稳定性进行深入研究 ,并探讨了天然草地植物群落的演替阶段 .应重视干旱区人工植被建设中对天然植被斑块格局和演替模式的模拟以及植被配置模式的研究 ,以指导自然植被的保护利用和人工植被的建设 .
Vegetation stability is a comprehensive chara ct er of vegetation community. The paper reviewed the studies on vegetation stabili ty according to the meaning, the conception, the maintaining mechanism and the m ethod of studies. The mechanism is discussed from the theory of diversity and re dundancy. The study of grassland ecosystem should be given more attention, espec ially the natural meadow. The structure and function of vegetation should be nee ded for further study of vegetation stability, the serial stage of vegetation co mmunity in natural meadow is discussed. The study of the framework of patch abou t natural vegetation, the imitation of succession mode and the mode of vegetatio n arrangement all should be considered in building the artificial vegetation in arid region, it will have effect on leading.
