The mangroves in Beihai, Guangxi are gone! It's not an invasion of alien species, it's not a natural disaster, what's the reason?

Guangxi Beihai Mangrove is the largest mangrove area in China. Marine forest? There are as many as 37 kinds of mangroves in it, which is a national key nature reserve and a relatively complete mangrove area. However, in recent years, mangroves have been seriously damaged, which is neither a natural disaster nor an invasion of alien species, but the result of irregular construction.

In fact, as early as 20 16, mangroves died in a large area due to illegal construction. At that time, the relevant units were required to modify the construction plan, and at the same time strengthen the supervision of the project, control environmental pollution, and reduce the impact on mangrove areas. However, by 20 17, there are still a certain number of illegal projects under construction, and a large amount of sewage and waste are discharged into mangroves. In addition, sewage directly led to the destruction of soil in mangrove areas, and a large number of kaolin suspended matter attached and accumulated, resulting in a large number of deaths of mangroves that could not carry out normal photosynthesis.

The reduction of mangroves has also affected the surrounding environment to some extent. Because of the decrease of mangroves, the water quality of the surrounding lakes and streams began to change, and the oxygen content around them also decreased obviously, which directly led to the destruction of the ecosystem in mangrove areas and the decrease of the number of organisms living in this area. Some large animals and birds moved out of the area directly. Due to sewage discharge, the number of vegetation began to disappear, and even the surrounding marine ecosystem was eroded. These root causes are all due to mangroves. ?

We have also taken corresponding measures for the destruction of mangrove areas, but due to lack of experience, high cost and great difficulty in restoration, strengthening the management of this area is still the focus now. At the same time, we also expect mangroves to restore their former glory as soon as possible.

Mangroves are an important part of the local ecosystem and an important bridge connecting the ocean and the land. It has many functions, such as preventing wind and waves, purifying air, fixing shore and carbon, and adjusting climate. It is also the habitat of many kinds of creatures, which has great biodiversity value.
