【摘要】 本文研究了泡泡刺群落的地理分布、生态环境和群落结构,并研究了建群种泡泡刺的形态解剖和水分生理特征。研究表明,泡泡刺群落在荒漠中广泛分布并能在严酷的生境中生存,这与孢孢刺的超旱生特性有关,如叶肉质,枝条灰白色,气孔下陷,栅栏组织发达,具贮水薄壁组织等。更多还原

【Abstract】 The community of Nitraria sphaerocarpa is typical plant community on the gravel desert of China. Its distribution is very wide.In this paper we have dealt with the geographic distribution, ecological circumstances, formation of plant community, and morphology, anatomy, water physiology of constructive species.The study shown that the community of Nitraria sphaerocarpa can distribute widely on the desert, and is able to exist under bitter habitat because it is relate to extreme xeric characteristics of Nitraria sphaerocarpa, for example, their leaves are fleshy, branches are grey-white, palisade tissues are developmental, and it has water storage tissue.There are over a half of plant species which are eatable to livestock in the plant community of Nitraria sphaerocarpa. It is wide natural pasture, and have got certain value of economy in the animal husbandry. Nitraria sphaerocarpa is also to have certain effect to wind-breaking and sand-fixing.更多还原
