Abstract:
The Minqin county is model desertification area. Nitariatangutorum community and Artemisiaarenaria community are the two most important natural vegetation communities in Minqin desert area. The significance is significant on studies with natural regeneration ability of vegetation for the vegetation restores and protects. The author has studied natural regeneration ability of Nitariatangutorum community and Artemisiaarenaria community by localization observation. The result show: 1) The Nitariatangutorum community and Artemisiaarenaria community have ability to produce the sprout in sand dune and bottomland. 2) The difference is very significant between the seedling density of Nitariatangutorum in the Nitariatangutorum community and the seedling density of Artemisiaarenaria in Artemisiaarenaria community. The difference of seedling density is not significant between sand dune and bottomland and Between different year. 3) There are positive correlation between density and precipitation about Nitariatangutorum in Nitariatangutorum community and about seedling Artemisiaarenaria in Artemisiaarenaria community. Especially positive correlation is more remarkable between seedling density and same year May's precipitation and annual precipitation.
