Origin

edit

Currently, most people in the city believe that Luoma Lake gets its name from its shape, which looks like the backbone of a horse. They insist that this lake is formed by nature.[2] Indeed, Luoma Lake was initially formed as a tectonic lake and enlarged by the change of river system. Due to the change in the course of the Yellow River which temporarily merged with the Si River and Huai River between the Song and Qing dynasties, the Yellow River flooded this area for several times and enlarged the surface area of Luoma Lake. During the past 300 years, the Yellow River brought sediments into Luoma Lake and created depositions inside the lake.[3] In the 1950s, dams were constructed around the lake and made the lake a larger semi-artificial reservoir.

History

edit

The history of Luoma Lake can be traced back to the period of Gaozong of Song. According to his autobiography, he came to this place and named it as Luoma, which literally means horse backbone.[1] Because "Luoma" shares the same pronunciation with the phrase "being removed from office due to corruption" in Mandarin Chinese, the county government of Xinyi renamed it "Longma Lake", which has been boycotted by local people.[4]

Ecosystem

edit

Due to its temperature and humidity appropriate for living, several species inhabit in Luoma Lake. Those species include phragmites, nelumbo nucifera, silver carp, Chinese white shrimp, and crab.[1]

Cyanobacteria Community

edit

A study was conducted in Luoma Lake in 2015 to investigate the factors that influence the cyanobacteria abundance. It suggests that this abundance has a positive relationship with the concentration of ammonium and a negative one with oxygen concentration.[5]
