The Sichuan Basin
The Sichuan Basin is an intact basin surrounded by mountains. With an average altitude of about 500 m and an area of about 180,000 km2, it is the fourth largest basin in China.
There is a 200 km-long and 40-70 km-wide plain in the northwest of the basin, which is the famous Chengdu Plain where the world famous Dujiang Weirs have long irrigated the fertile land. Since ancient times, this area has enjoyed a reputation as a "land of plenty".
The climate of the basin is warm in winter and hot in summer, with small temperature difference and plenty of rain. In winter, it is mostly cloudy and foggy.
