Haloxylon ammodendron community in different natural stands conditions along southern edge of Zhunger Basin were studied on its structural characteristics, seedling supplies and age structures for investigating their own population patterns. The results showed that climate change led to, temperature varied sharply and the rainfall reduced in the early spring in arid area. As a result, a large number of H.ammodendron seedling dead. The age structure of H.ammodendron was commonly decreasing in different natural stand conditions along southern edge of Zhunger Basin for the lack of seedling-supply from climate change over the past decade. Microhabitats,the cover of soil or thin sand stratum could protect the seedling, and more H. ammodendron seedling survived. As a matter of fact, H. ammodendron age structures in these microhabitats were increase.
