该区位于疏勒河中游。自然地理地带位置是东疆间山盆地戈壁省(自然省)。这里广泛地分布着暖温带荒漠—棕色荒漠士;具有倾斜地形、第四纪疏松沉积物、干燥气候、荒漠土壤和少量地表径流。区内地带性自然条件(热量、湿度、土壤、植被等)基本上是单一的。而景观分异是在非地带性因素(地面物质、风、水文地貌和地下水地球化学过程)的作用下进行的,所以,这里分为三个景观区。根据地带性和非地带性因素相互联系和相互作用的性质,形成了完整的自然区域综合体。1.南部景观区该区是在地质—地貌和地面组成物质的基础上划分的。因为景观分异是在非地带性洪积物(砾石)主导作用下进行的。形成荒漠岩漆。范围内广泛地分布着石膏棕色荒漠土、稀疏的荒漠植被。例如白刺(Nitraria Schoberi);普氏麻黄(Ephedra Przewallskii);沙拐枣(Coligonum mongolicum);红砂(Hololachne Soongarica)。以及弱矿化度地下水。这样,该景观是在非地带性组成成分作用下发生的,具有石质荒漠景观特征。2.中部景观区该区风力切割甚盛。到处都能看到大面积的细沙和粘土。区内草甸草原植被占优势。广泛地分...

本文报道了内蒙古阿拉善荒漠草地土壤7种微量元素的含量与分布类型。结果表明,Cu和Fe符合正态分布,Se、Mo和Co符合对数正态分布,Zn呈正偏态分布,Mn近似服从正态分布;7种元素中,除Se的平均含量介于我国土壤平均含Se量外,其余6种元素均程度不同地低于我国土壤相应的平均含量;土壤元素的含量与土壤类型有一定关系,本区风沙土的Se、Cu、Fe、Zn和Mn的含量很低,灰漠上的Se、Mo、Fe和Mn的含量也极低,淡棕钙土的Mo和Zn的含量贫缺,灰棕荒漠土的Cu和Zn的含量十分贫缺。

It was also foundthat the soil it grows on is rich in C1~- and SO_4~(2-). 2. Haloxylon ammode-ndron and Haloxylon persicum are similar in their chemical composition,both...

Through two short periods (1984, 1985) of field work, the author inve-stigated 10 plant communities and their soils and ground water in the QiraR. Basin of Southern Xinjiang and in the Manas R. Basin of NorthernXinjiang. The indicative significances of these 10 plant communities areas follows; 1. Tamarix ramosissima is a C1-and S-rich plant. It was also foundthat the soil it grows on is rich in C1~- and SO_4~(2-). 2. Haloxylon ammode-ndron and Haloxylon persicum are similar in their chemical composition,both the Na-rich plants. The relative Na~+ ion content of their soil aregreater than 50% too. 3. Reaumuria soongorica. In Southern Xinjiang, thisdwarf semishrub occurs on gravelly gobi of piedmont, while in NorthernXinjiang, it is found on the plain covered with loess or loessial material. The average salinity of the surface soil (0-30cm) is generally less than1%. 4. Karelinia caspica. This composite perennial is found to be a phre-atophyte. The depth of the ground water table is generally 3 metres belowthe ground surface. It is also an S-rich plant which may be used as anindicator of higher relative content of SO_4~(2-) ion in the soil. 5. Alhagisparsifolia is a leguminosae perennial, and has a deep root system.In Southern Xinjiang, it distributes generally in depressions among sanddunes and flat sandy plains. It is an indicator of fresh ground water. Thedepth of ground water table lies at about 5 metres below soil surface, andthe salinity of the soil is low. 6. Halimodendron halodendron. This is aphreatophyte too. In the Manas River Basin, it may indicate that the gro-und water table lies at a depth of 2-4m. Its ash content is rather low,and this may be due to the weak salinization of the soil. 7. Ephedra pr-zewalskii is a dwarf shrub, mainly found in Southern Xinjiang. It distri-butes on sandy gravelly piedmont gobi, with brown desert soil. In the soilprofile there exists an illuvium layer of gypsum. 8. Lycium ruthenicum.This solanaceae shrub is aa typical halophyte. The average sallnity of itssoil (0-30cm) generally exceeds 2%. It is a Na-and C1-rich plant. The re-lative contents of Na~+ and C1~- ion in the soil are rather high. 9. Artemisiaparvula always occurs on slopes covered with "Kunlun loess", it is a K-rich plant, and can be used as an indicator of high content of K elementin the soil.

本文对北疆玛纳斯河流域和南疆策勒河流域共10种植物群落与土壤和地下水的关系进行了初步研究,分析了一些植物的指示意义。1.多枝柽柳是一种富Cl和S的植物,它所生长的土壤中Cl_-和SO_4~(2-)的含量较高。生长多枝柽柳群落的土壤盐化类型一般为氮化物、硫酸盐型)。2.梭梭和白梭梭的化学元素类型很相似,它们都是富Na植物。土壤中Na~+离子的相对含量一般在50%以上。3.琵琶柴在南疆多分布在砾质戈壁上,在北疆则多出现于黄土状母质上。一般说来,琵琶柴生长地段0-30cm土层内的盐分平均含量不超过1%。4.花花柴是一种潜水指示植物,它的地下水深度一般不超过3m。花花柴也是一种富S植物,土壤中SO_4~(2-)离子的相对含量较高。5.疏叶骆驼刺是一种淡水指示植物。在南疆多生长在沙丘间低地和平沙地上。地下水深多在5m以下,土壤盐渍化较弱。6.铃铛刺也是潜水植物,在玛纳斯河流域它一般指示地下水深度在2-4m左右。该植物体内的低灰分含量与土壤弱盐渍化程度相联系。7.膜果麻黄生长在砾沙质的棕色荒漠土上,土体中有明显的石膏淀积层。8.黑刺是典型盐土植物,所在土壤0-30cm平均含盐量大于2%。黑刺是富Na和富Cl植...
