In the west qinling , qilian and longshoushan metallogenic zones , some larger - ultra larger mineral deposits were formed throughout a model of " bearing " in long course of geological evolution . studying their geologic setting of " formation " and condition of late " development " would help us to objectively realize rules for the metallization and enrichment and define reasonable thinking for research and plan for exploration 甘肃西秦岭、祁连、龙首山等成矿带的大型-超大型金属矿床，是在地质构造发展演化过程中“生长”而成的；研究分析其“生”成背景与后期成“长”的条件，有利于客观认识成矿与富集规律、合理确定研究思路与勘查方案等。
According to tectono - metallogenic setting in combination with main mineral distribution and metallogenic types and ore - forming epochs in this orogenic belt , the authors used the theory of metallogenic series to divide the deposits of the north qilian early palaeozoic convergent epicontinental cu , pd , zn , w ( mo ) , au , ophiolite metallogenic belt and the south qilian early palaeozoic epicontinental rifting cu , ni ( pt ) , cr , au , rare elements and pyrite metallogenic belt into six series 文章依据成矿构造环境，结合区域主要矿种分布及其成矿类型和成矿时代等特徵，应用矿床成矿系列理论，将祁连造山带北祁连早古生代汇聚陆缘铜、铅、锌、钨（钼） 、金、蛇蚊石成矿带和南祁连早古生代陆缘裂解带铜、镍（铂族） 、铬、金、稀土、黄铁矿成矿带中的矿床划归为6个成矿系列。
Based on an integrated analysis of the surface geological , aeromagnetic , gravity , mt and seismic data from the area of mangnai to serteng mountains in the western qaidam basin , the authors think that the qaidam basin is sandwiched between the north kunlun block and serteng tectonic belt , including two first - order tectonic units the qaidam block and the southern margin of the qilian block and four second - order tectonic units the northern margin of the north kunlun block , qaidam basin , serteng tectonic belt and suhai lake basin in the south of the qilian block 摘要通过柴达木盆地西部茫崖赛什腾山地表地质、航磁、重力、大地电磁测深和地震资料的综合分析，认为柴达木盆地夹持在昆北地块与赛什腾构造带之间，其中包括柴达木地块与祁连地块南缘2个一级构造单元和昆北地体北缘，柴达木盆地，赛什腾构造带和祁连地块南部的苏干湖盆地等4个二级构造单元。
Through the regional background analysis in which western structures developed , it suggested that there did not exist a united and steady block to the west of ordos basin . alashan block neighboring on the north of the western margin was largely influenced by the action of qilian and tianshan - xingmeng folded belt which is respectively to the south and north of alashan block , was narrow in the steady block and was limited by the longshou mountain - zhongwei strike fracture in the south area 通过对鄂尔多斯盆地西缘构造发育的区域构造背景分析，认为在鄂尔多斯盆地之西，一直没有一个统一的稳定地块相邻，与盆地西缘北部相邻的阿拉善地块，受南北相邻的祁连褶皱带和天山兴蒙褶皱带活动的影响，较稳定地块的范围比较狭窄，其南又有龙首山-中卫走滑断裂构造带存在。
By analysing the situation of copper mine resource home and abroad as well as supply and demand of market , the paper considers that carrying on the research on exploring the xuequan copper ( zinc ) depositis is of an important significance to searching and researching cyprus - type cu - rich massive sulfide deposits in north qilian mts . and ever in china 摘要通过对国内外铜矿资源状况及市场供需的分析，认为雪泉铜（锌）矿床勘查研究工作的开展，将对北祁连乃至中国与塞浦路斯型富铜块状硫化物矿床的寻找和研究具有重要意义。
According to the characteristics of strata , tectonization and magmatism within the research area in the southwest margin of north china paleocontinent , and under the ideological guidance of mobilism and systematology , the geotectonic framework of the area could be divided as follows : ( 1 ) the longshoushan mountains continental margin ; ( 2 ) the hexi corridor back - arc basin ; ( 3 ) the northern qilianshan mountains suture zone ; ( 4 ) the central qilianshan mountains dispersion type island arc terrane ; ( 5 ) the southern qilianshan mountains back - arc basin ; ( 6 ) the qaidam massif 根据本区地层、构造、岩浆作用特点，在“系统论” 、 “活动论”思想指导下，厘定华北古大陆西南边缘的构造格局如下：龙首山陆缘带、河西走廊弧后盆地、北祁连缝合带、中祁连离散型岛弧地体、南祁连弧后盆地、柴达木地块。
On the other hand for four main vegetation typies , which are picea crassifolia , forests sabina przewalskii forests , bushes and pastureland , whose soil permeability function was analyzed from angle of its physics , capacity of water , storing water in it . the results show as follow : permeability function of soil is controlled by quality of soil hole . the quality and quantity of soil hole under picea crassifolia forests are the best , and the permeability also is the best 另外，从土壤物理性质、蓄水量、贮水量等角度对祁连山苔藓云杉林、祁连圆柏林、亚高山灌丛林、牧坡草地4种主要植被类型的土壤渗透功能进行分析，结果表明：土壤的渗透功能主要由土壤非毛管孔隙度的质和量决定的，苔藓云杉林土壤非毛管孔隙度的质和量最好，它的渗透也最好；虽然亚高山灌丛林的渗透功能次之，但由于它所处的位置和面积大，现实贮水量在祁连山四种主要植被类型中最大。
Ecological features , function indicators and social - human impact together constitute the fundermental system of regional ecosystem health assessment . haxi forestry center is located in tianzhu of gansu province . in view of the natural conditions , land use type and forest map , we classify the research area into 15 landscape types 甘肃天祝县哈溪林区位于祁连山东段，依据哈溪林区的自然条件、土地类型和林相图，将研究区划分为苗圃，未成林地，宜林地，农田，牧草地，荒地，青海云杉林，祁连圆柏，针叶混交林，杨类阔叶林，红桦、榆、山杨硬阔林，针阔混交林、灌木林、疏林地和阔叶混交林等15种景观类型。
Under the strong compression from the orogenic belts on both sides , in the jurassic an atypical foreland basin developed on the southern margin of the qilian orogenic belt ; in the tertiary , a two - side foreland basin formed between the qilian orogen and kunlun orogen ; in the quaternary , the qaidam basin is a compressional , downwarped basin 在两侧造山带的强烈挤压作用下，侏罗纪时期在祁连造山带南缘形成并不典型的前陆盆地，古近纪至新近纪时期则在祁连造山带与昆仑造山带之间形成双侧前陆盆地，第四纪属挤压坳陷盆地。
