THE STUDY ON THE MIGRATION AND REGENERATION OF TAMARIX COMMUNITY IN GUERBANTONGUTE DESERT
在古尔班通古特沙漠中柽柳(TAMARIX spp.)群落的侵移与更新研究

It has been found that Tamarix can migrate and reside naturally in non-river-bank region of desert. The necessary conditions for the plant to ger-minate are: big rain fall, which leads to waterlogging in growth season,suitable soil structure and the seed source. These conditions are seldomlysatisfied in Xinjiang at the same place and time, thus the seedling groupis very rare, and the age distribution is uncontinuous. On the other hand,the bush wood usually has a long life. Without artifical disturbance, the-se bush woods will regenerate by filling up the seedling continuosly.
