中国的盆地集中分布在西部地区,塔里木盆地、柴达木盆地、准噶尔盆地和四川盆地为中国四大盆地。此外,还有一些面积较小的次一级盆地,如吐鲁番盆地、哈密盆地、江汉盆地等,面积约180多万平方千米,占国土地面积的19%。盆地是中国自然资源的聚宝盆。这些盆地部有长久的发育历史和形成过程,生成各种矿床,如石油、天然气、钾盐、钠盐、煤层和砂矿等。许多盆地地表有河流与冲积平原,保留有湖泊沼泽。其特殊的地下矿产与地表土地资源,水文、气候资源成为人类早期活动的场所,是近代工农业集中地区和未来经济开发的资源宝库。名词注解栏目将分期对中国四大盆地进行介绍。
The basins in China are concentrated in the western region. The Tarim Basin, the Qaidam Basin, the Junggar Basin and the Sichuan Basin are the four major basins in China. In addition, there are some smaller sub-basin, such as Turpan Basin, Hami Basin, Jianghan Basin, an area of about 180 million square kilometers, accounting for 19% of land area. The basin is a cornucopia of China’s natural resources. These basins have a long developmental history and formation process, generating various deposits such as oil, gas, potash, sodium salts, coal seams and sands. Many basins have rivers and alluvial plains on the earth’s surface and lakes and marshes remain. Its special underground mineral and surface land resources, hydrological and climatic resources have become the sites for early human activities, and are the treasure house of resources for the industrial and agricultural concentrated areas and future economic development in modern times. The noun comment section will introduce the four major basins in China in phases.
