Myspalax cansus (Rodentia, Myospalacinae, Myspalax)which lives on the loess plateau of our country. This unique underground rats life-long living under the cave, it developed many hypoxic tolerance protect mechanism to adapt its special circumstances at in organsall levels. In this study,we used Gansu zokor and SD rats (Sprague-Dawley)for the object, do serious hypoxia tolerance experiment, to explore the hypoxia tolerance extreme of Gansu zokor, analysis the difference hypoxia tolerance between Gansu zokor and SD rats at same oxygen concentration; The changes on their cardiac muscle organization structures in hypoxia tolerance process ; The expression of HSP70 between normoxic and hypoxic control in cardiac muscle organization of two animals , to find the relativity in all the results.

甘肃鼢鼠隶属啮齿目，鼢鼠亚科，鼢鼠属，是我国黄土高原特有地下鼠，由于终生营地下洞穴生活，使得甘肃鼢鼠发展出良好的低氧耐受保护机制，本研究以甘肃鼢鼠和SD大白鼠(Sprague-Dawley)为对象，进行低氧耐受实验，探寻甘肃鼢鼠的低氧耐受极限，比较二者低氧耐受的差异；以及低氧耐受不同时程，二者心肌组织显微和超微结构的变化差异；比较分析左心室组织中HSP70的表达变化和心肌耐受过程中组织结构变化的相关性。

Natural restoration of vegetation is an important approach to ecological restoration. The detailed investigation showed that the succession trend was quiet different under different site conditions. Stipa bungeana Trin dominated on south facing slopes and mountain tops while Artemisia Vestita Wall and A.

以黄土高原典型沟壑区―吴旗县为例，通过对退耕或封禁后植被自然恢复过程及其物种多样性的调查分析，结果表明，在不同的空间立地条件下，植被的演替变化规律不同：阳坡与峁顶的植被演替趋向形成以长芒草为主的群落类型，而阴坡则形成以铁杆蒿和茭篙为主的群落类型。
