The first tributary of the Yellow River refers to the river that flows into the Yellow River along the Yellow River basin. The Yellow River passes through nine provinces from Qinghai to Shandong, and 13 main tributaries flow into the main channel, gradually widening the river course and forming the vast water of the Yellow River. Originated in the Bayan Kara Mountains in Qinghai Province, China, it flows through Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong provinces, and finally flows into the Bohai Sea in Kenli County, Dongying City, Shandong Province.
Extended data:
The Yellow River basin has a vast territory, numerous mountains, great disparity in height difference between east and west, and great differences in landforms in different regions. Because the basin is located in the mid-latitude zone, the influence of atmospheric circulation and monsoon circulation is more complicated, so the climate difference in different areas of the basin is significant, and the annual and seasonal changes of climate elements are greater.
The total solar radiation in the Yellow River basin is moderate in China, with the area north of 37 north latitude and the plateau area west of103 east longitude between 130 ~ 160 kcal/cm2. Most of the rest areas are 1 10 ~ 130 kcal/cm2. Although it is not as strong as the southwest, especially the Qinghai-Tibet Plateau, it is stronger than the northeast and south of the Yellow River in general, and it is a strong radiation area in East China.
The annual temperature in the Yellow River basin varies greatly, and the general trend is that the area north of 370 north latitude is between 365,438+0 ~ 37℃, and the area south of 370 north latitude is mostly between 265,438+0 ~ 365,438+0℃. ?
The daily temperature range in the Yellow River basin is also relatively large, especially in the high latitudes in the middle and upper reaches. The daily temperature range of each season in the whole year is 13 ~ 16.5℃, which is in the national high value area or the second high value area.
