洪湖自然环境演变研究

Research on natural environment evolution of the Honghu lake

分析了洪湖形成、演变和自然环境变化的基本过程。在自然和人类活动作用下,洪湖的湖泊形态、水文条件、水质状况、水生植物和水生态系统以及江湖关系等都发生了一系列变化和演替。系统揭示了洪湖自然环境演变的基本过程和规律,表明近代人类活动进一步加剧了洪湖生态环境的退化。若对洪湖湿地重点保护,并采取有效的生态恢复措施,洪湖湖泊生态系统则处于良性循环中,否则,湖泊湿地可能会丧失。

This paper analyzes basic process of the formation, evolution and natural environment variation of the Honghu lake. For the natural and human factors, the lake pattern, hydrologic condition, water quality state, aquatic plant, aquatic ecological system and the relation of the Yangtze river and the lake etc. have changed. This paper analyzes the basic process and law of natural evolution of the lake environment, demonstrating that human factor aggravates degeneration of the lake natural environment. If the Honghu lake wet land is protected preferentially and effective ecological restoration measures are taken, the ecological system of the Honghu lake will be in favorable cycle state, otherwise, the lake wet land probably disappears.
