塔克拉玛干沙漠植被的生态学性质和持续发展

塔克拉玛干沙漠生态环境十分亚酷，植物多样性的组成有限。大多数植物的生存与一定的浅层地下水相联系，是一些中生、盐生和耐盐的种类，典型的沙生和旱生植物不多，由它们所形成的大多数植物群落也是中生性的。其分布格局明显受沙漠中水分状况的支配，表现为隐域分布性质。其中，荒漠河岸林的兴衰和更新，与荒漠河流水文特征适应，使其种群得以持续繁衍，保证了这一古老的第三纪落叶阔叶林，在沙漠中各大河流沿岸整体上的相对稳定性

The Ecological Features and Sustainable Development of Vegetation in the Taklimakan Desert

Because of adverse eco-environment,the phytodiversity is limited in the Taklimakan Desert. Most plants that belong to mesophyte, salt - talerant plant sand halophyte are mainly depended on certain groundwater. The distributing patterns of most plant communites are dominated by the water condition in the desert, so they are thought of as nonzonal vegetation. The growing state and renewal of the Tugayi forests are relative to the hydrological characteristic of rivers there and the forests show relatively stable as a whole. In recent decades,however,desert vegetation has been heavely destroyed and,in turn,the vegetation is faced with a serious crisis. The key factor to renew vegetation and develop sustainably is water that comes from floods and groundwater.
