This book is mainly about the environmental problems of this region of Tibet, as the main content of this book. The eastern and northern parts of Tibet are adjacent to Qinghai Province, Sichuan Province, Yunnan Province and Xinjiang Uygur Autonomous Region of the People's Republic of China. The west and south are adjacent to Myanmar, India, Bhutan and Nepal. Tibet is a part of the Qinghai-Tibet Plateau with an area of ​​about 1.2 million square kilometers, accounting for one-eighth of China's total area. The average height is over 4,000 meters above sea level. It is the highest and highest plateau in the world and one of the countries in China. autonomous region.

 

As for the total area of ​​Tibet lakes, it is about 23,800 square kilometers, accounting for about 30% of the total area of ​​the country's lakes. It has more than 1,500 lakes of various sizes. There are 47 lakes over 100 square kilometers. There are about 251 salt lakes with a total area of ​​about 8,000 square kilometers. The famous lakes include Nam Co, Yam Zhuo, Malang, Bangong, Ba Song, and Senli. These lakes have also become one of Tibet's natural features in the tourism industry.

 

This region is mainly the source of rivers in China and Southeast Asia. Therefore, if there are environmental problems, then the impact will not only be in Tibet, but in the entire Chinese land and neighboring Southeast Asian countries. So what are the main environmental problems in Tibet? This is the solution to the focus of the book and the solution to the environmental problems.

 

From the beginning, we can know from the Tibet study report that China's climate change national assessment report is from 1997 to 2001, the average temperature rose by 0.79 degrees Celsius, an average of 0.08 degrees Celsius per decade. At this time, we can understand that Tibet itself is being affected by the above-mentioned global warming.

 

Then we can compare the temperature of the Tibetan body. It can be seen that during the sixty years from 1961 to 2010, the average temperature change of the Tibetan Plateau increased by 0.37 degrees Celsius per decade. In the southern part of the Tibetan Plateau, the average temperature change in the Tibet Autonomous Region is 0.58 degrees Celsius per decade. This is also a temperature indicator set by the Paris Agreement.

 

Because glaciers are closely related to the supply of water, the stock of glaciers in Tibet is an indicator that affects everywhere. According to the report from 1980 to 2005. The area of ​​glaciers in Tibet decreased by 13.41 square kilometers, a decrease of 7.3% compared with the previous area.

 

The disaster that this will bring is the glacial lake outburst that occurred in Sanwang, in Kangma County, Shigatse region on July 16, 1954. The flood destroyed 170 large and small villages in Kangma, Jiangyan and Bailang. The affected people were 3,017 households, 16,180 people, 691 people died, 4,321 hectares of inundated farmland, 888 hectares were destroyed, 10074 houses were collapsed, and 8,679 dead animals were killed. It is nothing more than an environmental issue that is great for all countries.

 

Finally, the ecological crisis in the Tibetan Plateau is mainly based on 47 reports on different themes to illustrate the environmental crisis encountered in Tibet. For example, desertification, Tibet's hydropower development, and the South-to-North Water Diversion Middle Line project are closely related to the ecological maintenance of Tibet. From these issues, we also understand that environmental workers are endlessly sighing about Tibet's deteriorating living environment.

 

But as long as the first step is taken, then the ecological problem in Tibet is no longer just a bad situation in writing. One day, Tibet will slowly recover.
