湿地克隆植物的繁殖对策与生态适应性

湿地是地球上独特的生态系统，它是水陆交替的过渡带，而湿地植物为了适应这种特殊的环境，必须有其相应的生长格局（ｇｒｏｗｔｈｐａｔｔｅｒｎ）和繁殖对策（ｒｅｐｒｏｄｕｃｔｉｖｅｓｔｒａｔｅｇｙ）。有些湿地植物具有密丛型的生态特点，这是对过湿的土壤和氧气供给不足环境的一种适应方式。随着有机质的不断积累，每年从分蘖节向上长出新枝，向下生长不定根，其分蘖节不断上移，以便从地表面上获得氧气，并使植物体免遭埋没，这样年复一年的生长，在地表面上形成了草丘。生殖是生物繁衍后代延续种族最基本的行为和过程，它不仅是…

Advance in the Ecological Adaptability of the Clonal Plant in Wetlands.

Based on the information obtained from ecological adaptability researches of clonal population in the world, some concepts of clonal plant population ecology were defined. According to the special habitat of the clonal plant in wetlands, the adaptability of its growth pattern and its effect mechanism, i.e. the clonal plant through the change of the hormone balance (the ratio of IAA/IPA) adjusts the active intensity and controls the plant vegetative form, was discussed. The special propagate countermeasure and its reproductive allocation and investment was reviewed and discussed in detail. And the research methods currently available was also introduced. The scale of research perspective of ecological adaptability in wetland is suggested.
