The South-to-North Water Transfer Project is to transport the Yangtze River water to the north; The West-to-East Gas Pipeline Project transports natural gas from Tarim and Changqing gas fields in China to Shanghai, China. The total length of the pipeline is about 4,000 kilometers, and the designed annual gas transmission capacity is 654.38+0.2 billion cubic meters. The pipeline starts from Lunnan of Tarim, passes through Xinjiang, Gansu, Ningxia, Shaanxi, Shanxi, Henan, Anhui and Jiangsu from west to east, and ends in Shanghai. The pipeline * * * crosses (crosses) the Yangtze River, Yellow River and other large rivers for 6 times, medium-sized rivers for more than 500 times, trunk highways for more than 500 times and trunk railways for 46 times; It is about 2,500 kilometers across the seismic intensity zone of 6 degrees and below, 800 kilometers across the seismic intensity zone of 7 degrees and 700 kilometers across the seismic intensity zone of 8 degrees. Power transmission from the west to the east is to transmit electricity from the west to east China and other places.
