喀拉峻草原,位于我国新疆维吾尔自治区特克斯县南部的喀拉峻山地区。草原风景的主题主要指阔克苏河以东,南接琼库什台,包括琼库什台、克什库什台和席尔代峡谷,面积约759平方公里。喀拉峻草原是典型的山地草甸类型草原。“喀拉峻”是哈萨克语,“喀拉”有深色、浓郁和辽阔的意思,“峻”形容茂密的样子。从字面上理解,“喀拉峻大草原”可译为“苍苍莽莽的草原”。喀拉峻草原距特克斯县县城直线距离约30公里,有简易公路相通。 相似文献

康古尔地区位于疆东部北天一带。构造形迹复杂,构造位置独特。是以金为主的多金属矿成矿的有利地带。自20世纪80年代中后期在这一区开展了以金为主的多金属矿产普查工作至今,已发现金矿及金矿化线索50余处。本文将从金矿的成因类型研究出发,对康古尔地区金矿的形成条件,成因机理进行分析,并探讨其成矿规律。 相似文献

Following the greatest known end-Permian mass extinction plants have low diversity. Lycopsids and conifers dominated on land. A new gymnosperm Xinjiangoxylon gen. nov. is proposed based on a woody stem specimen collected from the Upper Permian （latest, Changhsingian） Upper Guodikeng Formation of the Taoshuyuan section, Turpan, Xinjiang Uygur Autonomous Region, Northwest China. The decorticated stem is characterized by a complex pith, endarch primary xylem and a thick secondary xylem cylinder. Numerous petrified woods were found in the Changhsingian at this section. However, there are rare wood fossils in the Early Triassic. The abrupt decrease of fossil woods worldwide relates to the crisis at the end of the Permian. Xinjiangoxylon turpanense gen et. sp. nov. appears to represents one gymnosperm that existed in the latest Permian. 相似文献

Underlying motivation for land use change: A case study on the variation of agricultural factor productivity in Xinjiang, China 总被引：1，自引：0，他引：1
Huiyi Zhu 《地理学报(英文版)》2013,23(6):1041-1051
Understanding the driving forces and mechanism of land use change is a key issue in land change science, and has received much attention over the past 30 years. While many driving forces have been identified, the mechanism of land use change is still unclear, mainly because of limited knowledge of the underlying motivation for land use change. Traditionally, the underlying motivation for land use change was ascribed to people＇s pursuit of satisfying their own demands or that of profit maximization. However, those theoretical hypotheses combine all productive factors without highlighting certain predominant factor, in this paper, a case study was conducted on the variation of land productivity, capital productivity and labor productivity in agricultural land use in Xinjiang Uygur Autonomous Region of China. The case study revealed that only labor productivity presented a long-term increasing trend in regional cotton and grain production. This result implies that people＇s pursuit of increasing labor pro- ductivity is probably the underlying motivation for land use change. Additional details identi- fied in agricultural and non-agricultural land use in China support the above implication. As labor productivity is a determinant of people＇s living standards, increasing labor productivity means improving people＇s living standards. Therefore, it is concluded that land use change results from people＇s pursuit of increasing labor productivity in a changing environment. 相似文献

以新疆西准噶尔地区阿克巴斯陶1∶50 000万岩屑数据为对象,利用相关、偏相关分析和R型聚类分析确定研究区成矿元素组合为Cu-Mo-Zn-W-Sb-Bi-As(铜钼成矿组合)与Au-As-Bi(金成矿组合);基于主成分分析,以线性方法将2组成矿元素重组为新的变量N1(Cu-Mo-Zn-W-Sb-Bi-As)与N2(Au-Bi-As),新变量中各元素权重根据主成分分析所得特征向量值大小决定;运用分形含量-面积法提取新变量异常下限并生成综合异常图。结合野外地质检查,成功圈定两处成矿潜力区,为下一步工作提供有力依据。 相似文献
