  glacier
Microorganisms Found in the Basal Horizons of the Antarctic Glacier above Lake Vostok
      
Problems of such kind arise in glaciology when one estimates the stability of snow on mountain slopes or determines the catastrophic movement of a glacier; the results can also be applied to solifluction phenomena [2, 3].
      
It was assumed that the temperature at the bed of the glacier could reach the melting point due to nonstationary heating and that the conditions would be produced for motion of the glacier.
      
Here we examine the nonstationary response of a glacier to small deviations of the system parameters from critical values corresponding to the stationary state.

Some samples from different geological origins and different geological ages are dated by means of ~(14)C using liquid scintillator method. The samples range from buried old wood in glacier deposits at 4200 and 3900 metersabove sea level in Xie-Cang(Tibet), the wood in karat cave of Qui-Zhow province and charcoal in civilization layers in Li-Yang of Jiang-Su Province with geological ages range from some 1,000 years to 7,000 years ago. The carbon is first converted into calcium carbide at 980C, then it is hydrolysed into acetylene and converted into benzene using silica-alumina catalyst. The catalyst was activated in chromic acid before using. The scintillator has 36 g PPO+0.6 g POPOP dissolved in one liter of Xylene. One mixes 1 ml. of Scintillator in each 5 ml. of benzene. The purity of benzene is controlled by ex-radioactive source channel compare method. The samples are contained in tiflon bottles of 8 ml. in capacity and is viewed by two photomultipliers in coincidence counting circuits. The counting time for each sample is 1,000 minutes for each rum. The data are corrected with Damon's table.

用液体闪烁法测定了不同来源、不同年代的地学样品的~(14)C年令。样品包括:西藏海拔3900米到4200米冰川堆积物中的木材,贵州喀斯特洞穴中的木材,江苏省溧阳文化层中的木材,地质年令自1000年到7000年。首先,碳在980℃温度下生成CaC_2,然后加水转变成C_2H_2,在硅铝球的催化下,C_2H_2转变成C_6H_6。硅铝球使用前用铬酸活化。闪烁液的浓度是36克ppo+0.6克popop/升二甲苯。每5毫升合成苯加1毫升闪烁液。通过外放射源道比法测定,证明合成苯达到闪烁纯。闪烁液置于8毫升聚四氟乙烯瓶中,用双光电倍加管符合测量~(14)C计数。每一样品测量时间是1000分钟。年令用Damon的树轮校正表校正。

The Gansu Corridr is located in inland Eurasian continent with extremearid climate. The ecosystems of agriculture, forestry and animal husbandryare very fragile and unstable. The glacier and snow line of the Qilian Mo-untains have drawn back so much as to reduce the total runoff to 88.23%,the spring water to 82.20%. The forest of the Qilian Mountains has serio-usly been damaged, that reduces the forest area by 16.5%. Therefore. it isan important strategy to recover the ecosystem and improve the agricultureand forestry of the Gansu Corridor. The efforts must be made to guard ag-ainst the retreat of the snow line and glacier, to protect and enlarge thewater-conserving forest, to plant shelterbelt in oasis area,to protect and cl-ose the natural vegetation, to ameliorate the water conservancy facilities andirrigation works, to raise the utilization ratio of water resources.

甘肃河西地区地处欧亚大陆腹地,气候极端干燥,年平均降水量约40—200mm。水源缺乏,农、林、牧生态系统十分脆弱。雪线与冰川后退,总经流减少11.77%,泉水减少17.8%。祁连山森林遭受破坏,森林面积减少16.5%,因此,恢复与稳定河西生态系统是发展河西工农业生产,改善人民生活环境的首要战略任务。主要措施是:防止雪线和冰川后退,保护和扩大祁连山水源涵养林,大力营造绿洲农田防护林,保护和封育荒漠天然植被,改善现有水利设施,加强水利工程建设,减少水份的散失量、提高水资源的合理利用率。

In the latest fourty years, the originally united Tarim river system has been disintegratedinto three parts, one of which, the Akesu river-Tarim river system, appears to have been aclosed independent river system. The Akesu river and Tarim river are located seperatedly at the southern slope and theforeland plain of Tianshan Mountain, the two morphological units, with their natural condi-tions being of quite difference. Owing to the high elevation and rich precipitation, the formeris characterized by intensive seasonal temperature change, relatively good vegetation andmodern glaciers distributed in its alpine districts. The latter, with quite little rainfall, issubijected to dry climate through the whole year. Since the sunshine time is long in theforeland plain, there is plentiful illumination and heat resource. The agriculture in the oasesmostly depends on the water resource from Tianshan Mountain. The Akesu river plays a keyrole in the agriculture development in the north Tarim Basin. Compared with the whole south Xinjiang, the natural condition is good in the region ofAkesu rivet-Tarim river. In the recent decades, the agriculture has been developed rapidly.Several large oases near the river occurred to have been the fundamental grain and cottonproducing bases of Xinjiang. The much more economic, social, ecological benefits will begained if we can utilize the natural resources better, make more reasonable arrangement ofproduction avtivities, consider the local conditions as a whole and pay more attentions to theecological environment.

本文把阿克苏河——塔里木河流域(简称阿——塔河流域)作为一个封闭系统,主要阐述流域的自然条件,并对自然条件在农业生产中的利弊进行了全面分析。指出在干旱地区农业开发中,必须统筹安排,全面规划,上中下游合理利用,重视保护脆弱的生态环境,才能取得经济效益、社会效益与生态效益的全面收获。
