Historical evolution

On January 1, 1990, Guangdong Provincial Government approved the establishment of Zhanjiang Mangrove provincial nature reserve. The purpose of the reserve is to protect mangrove related bird resources. It is located in Gaoqiao Town, Lianjiang City, covering an area of more than 2000 hectares.

In 1992, with the approval of Guangdong Provincial Forestry Bureau, the provincial nature reserve management station was established in Gaoqiao Town, Lianjiang City.

In 1995, Zhanjiang municipal government applied to expand the protected area and upgrade it to a national protected area.

On November 7, 1997, with the approval of the State Council, it was upgraded to a National Nature Reserve and renamed Zhanjiang Mangrove National Nature Reserve.

In 2001, the project of mangrove comprehensive management and coastal protection, a bilateral cooperation project between the Chinese government and the Dutch government, was officially launched in Leizhou Peninsula. One of the important objectives of the project is to improve and strengthen the institutional capacity-building to meet the requirements of the protection and management of the reserve.

In 2002, Zhanjiang Mangrove National Nature Reserve was listed as an important international wetland by Ramsar Convention organization.

climate

Zhanjiang Mangrove National Nature Reserve is located in the transition area from the north to the south. The south is the North tropical monsoon climate area, and the north is the south subtropical monsoon climate area. It is greatly affected by the monsoon climate and marine climate. The annual average temperature is 23 ℃, the extreme maximum temperature is 38.8 ℃, and the extreme minimum temperature is - 1.4 ℃. The average annual precipitation is 1534.6 mm. The dry and wet seasons are obvious. The rainfall is concentrated from April to September. It is also a typhoon rainstorm season. There are many thunderstorms. The typhoon brings rainstorms and waves to the coast, which has huge damage energy.

hydrology

Mangrove swamp in Zhanjiang Mangrove National Nature Reserve originated from natural coastal swamp. There are Jianjiang River, Jiuzhou River and Nandu River. Each river carries a large amount of fresh water and nutrients and sediment lost from land into the sea every year. The salinity of the water quality at the confluence of fresh water and tidal saline water presents a gradient change, about 1% - 3%. The salinity is mainly affected by the periodic changes of tides and rainfall seasons. The beaches with different salinities at the estuary provide suitable sites for mangrove plants with different salt tolerance . The tides on the East and west sides of Leizhou Peninsula are different. The tides on the east coast are irregular semidiurnal tides, while those on the west coast are irregular diurnal tides.

terrain

Leizhou Peninsula, where Zhanjiang Mangrove National Nature Reserve is located, has a relatively flat terrain and complex coastline. There are many islands near the peninsula. Except for the rugged coast at the southern end of the peninsula, the beaches on the East and west sides and adjacent islands are very small slopes.

soil

The mangrove swamp soil in Zhanjiang Mangrove National Nature Reserve of Guangdong Province is mainly saline swamp soil formed by the accumulation of shallow sea sediment, tide and river transport under the growth of mangrove.

Botany

There are 24 species of 15 families and 24 species of mangrove trees in Zhanjiang Mangrove National Nature Reserve of Guangdong. The main associated plants are 21 species of the Chinese mainland. Among them, Avicennia marina, Aegiceras corniculata, mangrove, Kandelia candel and Bruguiera gymnorrhiza are the most widely distributed and the most abundant. The main forest vegetation communities are Avicennia marina, Aegiceras corniculata, Kandelia candel and mangrove pure forest communities and Avicennia marina + Aegiceras corniculata, Aegiceras candel + Kandelia candel, Aegiceras candel + mangrove communities. The stand canopy density is above 0.8.

Marine organisms

There are 110 species of shellfish belonging to 38 families, 76 genera, 3 classes and 127 species of fish belonging to 100 genera, 58 families, 15 orders in Leizhou Peninsula mangrove area. Shellfish are the largest species of the family clam family, and 20 species are found. 4 species of clams, green dung, caps, striped snails and ferrets are found in the Chinese mainland coast. Perciformes are the most dominant fish species, with 65 species belonging to 49 genera and 27 families. There are 28 species of shellfish and 32 species of fish with important economic value.

birds

Zhanjiang Mangrove National Nature Reserve is not only an important habitat for resident birds, but also a main foraging place for migratory birds. In addition to a large number of gulliformes, Passeriformes and other resident birds, a large number of migratory birds (including cranes, storks, herons and raptors) stop in the reserve on their way from Japan, Siberia or northern China to Australia every autumn and winter. According to the survey, there are 194 species of birds in the reserve, of which 32 are under the second level protection of the state, 117 and 39 are included in the agreement on the protection of migratory birds between China, Japan and Australia.

Management organization

There are four functional departments including office, scientific research and education department, resource management and protection department and Sustainable Utilization Department, and six management stations including Xuwen, Leizhou, Suixi, Lianjiang, Donghai and Mazhang.

Development and construction

Jiulongshan Wetland Park was declared by Zhanjiang Mangrove National Nature Reserve Administration and local government to the State Forestry Administration in 2009, and was approved for pilot construction at the end of the same year. It is the first national wetland park named after mangrove in China.

ecological value

Zhanjiang Mangrove National Nature Reserve has become an important international wetland, a national demonstration nature reserve construction unit, and a Chinese people and biosphere reserve. It is an important area of coastal protection forest construction system and wetland protection project in China. Mangrove wetland in Zhanjiang is the essence of wetland resources in southern China. It is an important buffer zone and carbon sequestration zone to cope with global climate change. It plays an important role in purifying seawater, regulating solar term, protecting coastal areas, preventing and reducing disaster, protecting biodiversity and safeguarding ecological security of land.

Zhanjiang Mangrove National Nature Reserve, as the largest existing Mangrove Nature Reserve in China, plays an increasingly important role in controlling coastal erosion, conserving soil and water, and protecting biodiversity. At the same time, Zhanjiang Mangrove National Nature Reserve plays an important ecological role in resisting typhoon, slowing down tidal flow, promoting land formation, protecting embankment, absorbing and transforming pollutants, and purifying seawater.

Mangrove is a woody evergreen plant community growing in tropical and subtropical bays and estuaries. It is graceful in shape and unpredictable in the ebb and flow. Because it grows on the saline soil flooded by the sea tide for a long time, it forms a unique ecological environment
