Characteristics of Plant Life Form and Floristic Geography in the Core Producing Area of Zhongwei Goat,Ningxia

Plant life form and floristic geography were studied in the core region of Zhongwei goat (a special goat for their fur in the world).The result showed that characteristics of all flora development embodied the action of the droughty environment.The floristic element of flora was very vulnerable,and the most species was temperate element.Plants of hemicryptophyte,droughty types and ephemeral plant were most,what reflected coefficient of several factors including droughty environment,microrelief of mountainous area and the long-term disturbance of grazing.
