青藏高原隆升对中国疆域自然环境的影响：破解“胡焕庸线”的思考

我国疆域广大,人口、土地、耕地和发展程度很不均衡。1933年,知名学者胡焕庸据此提出了著名“胡焕庸线”。利用这条北东南西走向直线,将中国大陆划分为东西两个部分。该线的东、西两侧差异悬殊。究其原由,制约因素的多元的,而近地表的自然环境和地球内部物质与能量的交换起着重要作用。研究与探索表明:(1)印度次大陆与欧亚大陆两陆—陆板块的碰撞—挤压驱使高原南缘喜马拉雅造山带的突起是根本原因。(2)喜马拉雅造山带的突起阻隔了印度洋南来温湿气候的北进,并形成了西风带造成了我国西北地域的干旱和荒漠化。(3)在力系作用下,壳、幔物质重新分异、调整,地壳短缩增厚、高原整体台升不仅导致东、西两部降水量、气温、人口、耕地与生态环境的显著改变,且地球物理场发生了强烈变异与分布不均。(4)西部发展的关键在于水,水进则人进,人进则文化进,文化进则科技进,科技进则发展快,西部人民生活与生存环境不断优化,社会则更安宁。(5)东部不断强化开辟地下空间与利用,西部期盼“红旗河”工程实施,维护生态环境,兴建亿亩现代化耕地、牧场与绿洲。我国东部与西部共同发展与建设十分重要,饭碗要永远端在自己手中。

Huge difference of development and uplift of Tibet and influence in Earthen region and western region of China

China has a vast territory, with a very uneven population, land, arable land, and development level. In 1933, renowned scholar Hu Huanyong proposed the famous " China has a vast territory, with a very uneven population, land, arable land, and development level. In 1933, renowned scholar Hu Huanyong proposed the famous "Hu Huanyong Line" based on this. The Chinese Mainland is divided into east and west parts by using this straight line of north southeast west trend. There is a significant difference between the east and west sides of the line. The reasons for this are multifaceted, and the natural environment near the surface and the exchange of material and energy within the Earth play an important role. Research and exploration have shown that: (1) the collision and compression of the Indian subcontinent and Eurasian continental plates driving the uplift of the Himalayan orogenic belt on the southern edge of the plateau is the fundamental reason. (2) The protrusion of the Himalayan orogenic belt obstructs the northward movement of the warm and humid climate from the south of the Indian Ocean, and forms the westerly belt, causing drought and desertification in the northwest region of China. (3) Under the influence of force systems, the crustal and mantle materials undergo re differentiation and adjustment, resulting in crustal shortening and thickening, and overall plateau uplift. This not only leads to significant changes in precipitation, temperature, population, arable land, and ecological environment in the eastern and western regions, but also leads to strong variations and uneven distribution of geophysical fields. (4) The key to the development of the western region lies in water. If water enters, people will enter, culture will enter, culture will enter, technology will enter, and technology will develop rapidly. The living and living environment of the people in the western region is constantly optimized, and society will be more peaceful. (5) The eastern region is continuously strengthening the development and utilization of underground space, while the western region is looking forward to the implementation of the "Red Flag River" project, maintaining the ecological environment, and building billions of acres of modern farmland, pastures, and oases. The joint development and construction of the eastern and western regions of China is very important, and the rice bowl must always be in one"s own hands." based on this.
