Additional info: Background Introduction. Outside the ecological tanks that are used to themes of jungle black water, marsh wetlands, plain rivers and lakes, there are actually more magnificent habitats on earth. The modeling object of the original water feature. Because of the documentary filming, the theme water feature of the Qinghai-Tibet Plateau entered my topic. From April 2019 to the present, my crew and I. I have participated in the shooting of scientific expedition documentaries of the Institute of Fishery Sciences of the Tibet Autonomous Region Academy of Agriculture and Animal Husbandry Sciences. I have followed the scientific expedition team more than 5 times. The cumulative days have been more than 3 months. Over 100 water areas (rivers, lakes, wetlands). At the time of publication, my film crew was still fighting side by side with the expedition members in the mountains of Nyingchi-Motu. The spring and summer in the Himalayas were short. Taking advantage of the short plateau summer, my film crew and I used the lens Record the “recovery and rebirth” of the Qinghai-Tibet Plateau in a year that was not sought.

In Nyingchi area, the annual rainfall is about 650 mm, the average annual temperature is 8.7 ℃, the river velocity is as high as 16 meters / second, the flow rate is 4425 cubic meters / second, and the annual runoff is 22 billion cubic meters.
