Sihong Hongze Lake Wetland Scenic Area covers an area of 5.2 square kilometers and is divided into five major tourist areas. There are more than 30 scenic spots such as Wetland Museum, Reed Labyrinth and Heqian Garden, and comprehensive service facilities such as training center and fish house are built. The water quality of Hongze Lake is good, reaching the national second-class standard; The vegetation is good, and hundreds of aquatic plants are all over the wetland. Lotus and reed are the protagonists, forming a green barrier and a life home.
Reasons for the formation of Hongze Lake:
1. The depression formed by crustal fracture is a natural factor for the formation of Hongze Lake, and the embryo began in the small lake before Tang and Song Dynasties. There are mainly Fuling Lake, Pofu Creek, Mudun Lake and Wanjia Lake.
2. The Yellow River's capture of Huai River is an objective factor to form the embryonic form of Hongze Lake. In the fifth year of the Song Dynasty (A.D. 1 194), the Yellow River decided to take it, and it was divided into north and south branches on the Liangshanpo. The south branch joins Surabaya and flows southward into the Huaihe River, which is the beginning of the diversion of the Yellow River. In the fifth year of Xianfeng in the Qing Dynasty (AD 1855), the Yellow River moved north and entered the sea from Lijin. The Yellow River occupied the Huaihe River for nearly 700 years. Because the Yellow River is condescending, it flows into the Huaihe River, where Huanghuai meets, the flow increases and the water level rises, connecting small lakes and depressions such as Fuling Lake and Broken Kettle Pond into a lake.
3. Building a high weir (Hongze Lake levee) is a man-made factor and a decisive factor for the complete formation of Hongze Lake.
