It was suggest that the yield of tobacco in unit area was significant increasing and the quality was improved along with the altitude increase in Liuyang tobacco area. The tobacco leaves production at the place where the altitude from 400 meter and 900 meter was propitious to postpone the bearing period and growth and development of tobacco plants. It was the base of maturation endurance and could advance the tobacco leave maturation degree of all parts of tobacco plant. And it could hasten the orange tobacco leave ratio of the whole tobacco plant. It was boosted leaves unwrapping of top tobacco plant and the statuses of tobacco leaves, especially the top leaves, were significantly improved. The tissue structure of all parts leaves on tobacco plant were more loosen and the colour and luster of tobacco leaves was more vivid. The nicotinamide content in top leaves were digressive at a certain extent, on the contrary, the contents of the reductive sugar and kalium were increased at different extent. At the same time, it was benefit to play down the pesticide rudimentai of tobacco leaves and increased security of tobacco leaves.

结果表明：在浏阳烟区随着海拔高度的增加，单位面积烟叶的产量有着明显的增加，烟叶质量也有一定程度的改善；在海拔400—900m的地方进行烟叶生产，有利于延长烟株大田生育期，有效缓解浏阳烟区7、8月份的高温逼熟现象，有利于烟株的生长发育，为养好烟株的耐熟性打下良好的基础、促进各部位烟叶成熟度的提高；同时可以有效的促进烟株各部位橘黄烟叶比例的上升，对上部烟叶的开片也有着明显的促进作用，烟叶身份特别是上部烟叶的身份得到明显的改善，各部位烟叶组织结构更加疏松，烟叶色泽更加鲜亮；上部烟叶烟碱含量在一定程度上有所降低，各部位烟叶还原糖、钾含量有着不同程度的增加烟叶香气特征更加明显；香气量有一定程度的增加，吸位更加醇和、余味舒适；同时也有利于减少烟叶的农药残留量，提高烟叶的安全性。

"71" Glacier is located 116 kilometers southwest of Jiayuguan City Department Qilianshan hinterland, it is by the Lanzhou Branch of Chinese Academy of Sciences of the scientific and technological workers and the former Soviet Union experts in glaciology July 1, 1958 discovered and named after the date of discovery of a Plateau glaciers.xie gua in the slope of the glacier is less than the slopes of 45 degrees, the average ice thickness of 78 meters, the Department up to 120 meters thick, Bingfeng 5150 meters above sea level, 4300 meters above sea front tongue.

"七一"冰川位于嘉峪关市西南116公里处的祁连山腹地，它是由中国科学院兰州分院的科技工作者和原苏联冰川学专家于1958年7月1日发现、并以发现日期命名的一座高原冰川。该冰川斜挂于坡度小于45度的山坡上，冰层平均厚度78米，最厚处达120米，冰峰海拔5150 米，冰舌前沿海拔4300米。

Habitat selection of goral was mainly influenced by distance to human disturbance, altitude, distance to forest edge, distance to water source, slope position, shrub canopy cover, shrub height, level of concealment, slope aspect and wind direction.

因子分析表明，影响矮岩羊生境选择的主要因子为人为干扰距离、海拔高度、林缘距离、水源距离、灌丛高度、隐蔽级、风级和动物干扰距离等生境因子，而影响斑羚生境选择的主要因子为人为干扰距离、海拔高度、林缘距离、水源距离、坡位、灌丛盖度、灌丛高度、隐蔽级、坡向和风向生境因子。

It indicates that these changes may closely relate with gastrointestinal habitude in humans and gastrointestinal diseases in plateau. The changes of level of ET and CT are not notable with the rising altitude
