The lakes of Xinjiang have had greatly changes since liberation. All the lakes there can be divided into 5 types according to their change in area.. 1. dried up, 2. almost dried up, 3. shrinking, 4. changed mot much and, 5. expanding.The lakes in desert area tend to dry up, (for examples, the Nop Nor, the Manasi lake etc.) the lakes in the plain tend to shrink, (the Bositeng lake, the Wulungu lake etc.) and the lakes in mountain area remain their niginal out-look, (the sailimu lake, the Kanasi lake etc.)Recent changes in the lakes mainly include salinization of water quality and shrinkage in area and deepth. In the year 1958 the mineralization of the Bositeng lake was less than 0.4g/l, while in 1975 it rose to 1.5g/l, and in 1980 to 1.8g/l.The average annual increase was 0.06g/l which is quite amazing, in the year 1959 the Wulungu lake was 482.8 M. above-sea-level, while in 1969 it went down to 480.0 M. and in 1980 to 478.8M. 4 M. It has a total drop of about the last two decades.These changes make a profound impact on the ecosystem of the lakes. The area of desertifaication increased rapidly from 12% to 52% during the year from 1958 to 1978 around the Nop Nor region where a big lake had disappeared Biological resourses were degenarated in most of the lakes. Fishery output of the Wulungu lake decreased from 4000 tons to less an one thousand ton per years.Reed resourses of the Bositeng lake decreased from 0.4 million tons to 0.25 million tons per year during the same period.The cause of the changes is basically due to the influence of human activities. Large-scale reclamation reeds a huge amount of irrigation water from the rivers and it has to drain off salt water into the lakes. On the other hand, recent cyclical decrease of runoff is another important reason of the changes.The methods to prevent the lakes from becoming arid land and the way to utilize the lakes for multiple purposes are also discussed

三十年来,新疆湖泊发生了较大的变化,按湖泊水面变化可分为干涸、基本干涸、缩小、变化不明显和扩大等五种类型,本文简要分析了湖泊变化的原因,湖泊变化和自然环境之间的关系。

This paper deals with distribution of titahium, zirconium and yttrium as index elements based on analytical data of soil samples collected from area of Tulufan, Xinjiang. They are derived from eight parent materials. Contents of Ti, Zr and Y were determined by X-ray fluorescence, with Ti and Zr the hightest in soils from andesite, while that of Y is comparatively high in soils from alluviation sediments. No obvious difference is found between Ti, Zr and Y in topsoil and bedsoil, except for Ti and Y in...

This paper deals with distribution of titahium, zirconium and yttrium as index elements based on analytical data of soil samples collected from area of Tulufan, Xinjiang. They are derived from eight parent materials. Contents of Ti, Zr and Y were determined by X-ray fluorescence, with Ti and Zr the hightest in soils from andesite, while that of Y is comparatively high in soils from alluviation sediments. No obvious difference is found between Ti, Zr and Y in topsoil and bedsoil, except for Ti and Y in soils from wind deposits, lake sediments and shale.

本文根据新疆吐鲁番地区八种母质发育的土壤中Ti、Zr、Y的X射线荧光法分析数据,对这三种元素在土壤中的分布以及用它们之间的比值来判断该地区土壤剖面各层次的母质来源是否相同等问题进行初步探讨。结果表明,不同母质发育的土壤中元素含量有一定差异,而在大多数母质发育的土壤的表、底土间元素含量无明显差异;该地区土壤中zr/Y比和Ti/Zr比可用来判断土壤剖面不同层次的母质来源,两个结果较为一致,对于各层次间元素对比值较接近的剖面,认为是同一母质来源。

The changes in the ecological environment caused by human activities in Xinjiang are mainly as follows:1. The flowing distances of rivers have been shortening, and the mineralization and silt content of their water have been increasing.2. The water level of lakes has been descending, or they have been drying up, their water mineralization has been rising.3. Forests have been being damaged, the area has been reducing.4. Pastures have been retrograding, the herbage yield has been dropping, and the quality...

The changes in the ecological environment caused by human activities in Xinjiang are mainly as follows:1. The flowing distances of rivers have been shortening, and the mineralization and silt content of their water have been increasing.2. The water level of lakes has been descending, or they have been drying up, their water mineralization has been rising.3. Forests have been being damaged, the area has been reducing.4. Pastures have been retrograding, the herbage yield has been dropping, and the quality deteriorating.5. Soils have been suffering from the secondary salinization, swamping and their fertility has been lowering.6. The area of desertification has been expanding continuously.In order to protect and improve the ecological environment, the water and soil resources to a better use must be put, the natural vegetative cover should be protected and expanded, the desertification, salinization and swamping should be prevented, and the relationship between human beings and nature be coordinated.

人类活动引起的新疆生态环境变化主要有以下几方面:1.河流流程缩短,河水矿化度和泥沙含量增加;2.湖泊水位下降,湖面缩小或变干,湖水矿化度升高;3.森林破坏,面积缩小;4.草场的产草量降低,牧草质量下降; 5.土壤次生盐渍化、沼泽化和肥力下降;6.土地沙漠化不断扩大。
