The general structure of the basin is marked by the tectonic framework of compressional ramp of the east kunlun mountains and the qilian mountains toward and subsidence of the central part of the basin 盆地的总体结构表现为东昆仑山和祁连山相向向盆地挤压对冲，盆地中部沉降的构造格局。
Drive along the wai huan rd . ( outer ring ) , then get of at zhen nan rd . exit . drive towards esat along the zhen nan rd , then turn right at qi lian shan rd , go ahead for 300m then tum right to sui de rd 外环线真南路口下，沿真南路东行（进市区方向） ，至祁连山路向南右拐，行至绥德路向西右拐大致三百米即至。
The genetic variation of eight isozyme expressed by twelve gene loci among 3 natural populations of picea crassifolia was studied by the aids of page electrophoresis 摘要采用聚丙烯酰胺凝胶电泳实验对青海云杉的3个天然群体（甘肃祁连山、青海大通，甘肃甘南州）的12个基因位点表达的8种同工酶的遗传变异模式进行了研究。
It is concluded that the chemical constituents cluster of glacier melt water in the qilian mountain is the highest one in the region , and the glacier melt water is the main groundwater replenishment source 计算结果表明，祁连山冰川融水自身化学成分在该地区聚类最高，多次聚合说明祁连山冰川融水是该地区地下水补给源。
Adopting on - the - spot investigation and data analysis , it was studied that shrubbery disaster that qilian mountain for nature reserve suffered were global change , man - made destruction , disease and insect , and fire damage 摘要采取实地调查与资料分析方法，研究了祁连山自然保护区灌木林遭受的灾害主要为全球环境变化、人为破坏、病虫鼠危害及火灾危害4种。
2 . by detection and analysis on litter accumulation , water ? olding capacity of the litter and interception of main types of forests , its waterolding capacity , intercepting role , water storage and soil reduction of litter were studied 2通过对祁连山水源涵养林凋落物累计量、枯枝落叶持水能力以及截留作用测定分析，研究了枯落物叶层的持水、截留作用和蓄水保土效益。
E . , picea crassifolia forest , sabina przewalskii forest , shrubs and grazing land , soil water dynamics was revealed . transformation feature and availability of water moisture content for main vegetation type were studied and evaluated 3对祁连山林区云杉林、圆柏林、灌丛林、放牧草地等4种主要植被类型土壤水分动态研究，揭示出生长季节内各植被类型的土壤水分动态变化规律。
Three case study areas have been chosen in the paper , i . e . watershed forest resources of muchuan county of sichuan province , qilianshan and miyun county , which are the representative of the middle of yangtze river , the north of china and northwest of china respectively 研究中选取了三个案例点，即分别代表长江上游、西北、华北地区的四川省乐山市沐川县的水源涵养林区、祁连山水源涵养林区、密云县水源涵养林区。
Based on field investigations , with the help of the theories and methods of systematics and complexity science , the function status of the water resources conservation forest in qilian mountains was re - oriented , and the main problems in the forest management at present were analyzed , and scientific practical management countermeasures were put forward in this study 摘要该文在实地调查的基础上，采用系统科学和复杂性科学等新理论与新方法，重新定位了祁连山水源涵养林的功能地位，诊断了现阶段水源林经营中存在的主要问题，并针对问题提出了经营对策。
4 . the study on the frozen soil feature and its influence on the runfall of the catchment in qilian mountains . the results indicated that the soil begins to freeze around october 20 , and finishes melting around august 20 of next year . altitude slope side , vegetation condition of the land and temperature are the factors influencing the depth and the time of soil 4对祁连山区冻土特征及其对流域径流的影响研究表明，祁连山林区土壤每年的10月20日左右开始冻结，较低海拔的到第二年的8月20日左右消融结束；海拔、坡向、植被、下垫面状况、温度是影响冻土深度、早晚的制约因素；冻土厚度与径流量成反比关系。
