Yuncheng Salt Insurance Center launched the Salt Lake Water System Survey Day 311

Relevant reports have been reported since the 1980s.

There were only 4 types of initial reports. By 2006, it had reached 5 222 species. Among them, many of them were discovered in China. For example, the barrel -shaped algae in 1990, the Yuncheng wheel algae reported in 1991, the gray wheel algae, the 20 planki diatoms reported in 1993, the Yuncheng diamond -shaped algae reported in 1994, and the salt changed in 1999 Cygenic algae and Shanxi checked algae.

It can be seen that the naming of many new species of algae is directly crowned with the word "Yuncheng", which fully demonstrates the uniqueness of the algae in the salt pond.

In salt ponds and its surrounding waters, the salt content of salt pond is the highest. As the water body continues to extend, the amount of salt contains decreases in turn. According to different salt content, experts divide them into high salt water, real saline, mixed saline body and freshwater body.

According to reports, the freshwater body is mainly composed of some streams on the middle of the south of Yanchi and Anyi Reservoir, Bayi Reservoir and Fancun Reservoir near the north. In addition, many ditches and ponds on the periphery of Yanchi also belong to freshwater body. The salinity does not exceed 0.5, the Bomei is generally less than 1, and the pH value is between 7 and 8.9.

The mixed salt water body is mainly composed of the nitric pool beach, northern gate beach, and the Tangli beach and duck pond in the east. Some ditches and ponds near Salt Pond also belong to the salt mixed body. The salinity is between 0.5 and 30, the Bomei is between 1 and 3, and the pH value is between 7.5 and 9.

The real salt water body is mainly composed of ditches and ponds around the salt pond and the pond next to the salt pond. The salinity is between 30 and 40, the Bomei is between 3 and 5, and the pH value is between 7.5 and 9.

The high salt water body is mainly the center of salt pond, with a salinity of more than 40, Bomei between 5 and 27, and between 8 and 9.

Experts said that among the algae plants identified by Yancheng salt pond, there are 8, 39 subjects, 84, and 182 species of freshwater water bodies. There are 5 doors, 14 subjects, 20 genus, 28 species, and 3 doors, 4 subjects, 6, and 12 species are distributed in high salt water bodies.

Researchers will include a subject that is greater than or equal to 5 or the number of species is greater than equal to 20, which is defined as an advantageous subject. According to this standard, the algae plants in Yanchi Lake District, Yuncheng include 7 advantageous departments of the family of tremora, flat lobe, seal -shaped algae, bridge crooked algae family, nude algae family, grid family, and small ball algae family. Among them, there are 98 species of 11 families (including variants), and the diatom doors have 140 species of 11 subjects (including variants), and the green algae gate has 23 families of 54 genera (including variants).

The distribution of algae plants in water in different salinity changes significantly, and generally, it has the advantage of cyanococular doors, green algae doors, and diatom doors, but the proportion is obviously different. With the increase of salinity, the types of green algae doors have decreased, and the types of cyanococular doors and diatom doors have increased.

In addition, the type of saline and high saline body is significantly reduced compared with the freshwater body and the mixed saline body. This distribution is similar to the results of the research results of the salt lakes of the Qinghai Chaidama Basin, the Sall Lake Salt Lake in Inner Mongolia, and the salt lake in Zhangjiakou, Hebei.

Experts say that most types of tolerance to salinity are poor, only distributed in freshwater and mixed saline body. Some species have a large range of adaptation to salinity, and are distributed in several water bodies, such as several species of cyanobacteria, large spiral alcohol, blunt top algae, large sheath silk algae, and small green algae doors. Ball algae and a variety of diatom doors. There are also a few species only distributed in water body with high salinity, such as salt Sali.

According to reports, most of the diatom doors in Yanchi Lake District in Yuncheng are occasional species. Only a few species can form advantageous species in the water body, such as elbow -shaped needle algae, dull crispy rod algae, muminic algae, boat -shaped algae algae, boat -shaped algae Wait. In addition, there are many types of green algae distributed in fresh water, especially in some organic quality water bodies. The green algae grows strong and there are many types. There is only one green algae in the high salt water body, namely the salt Sumi Du's algae.

Experts believe that in -depth research on Yuncheng's salt pond algae is very necessary.

First of all, while developing salt ponds, the protection of salt pond resources and environment should be strengthened so that it can truly achieve sustainable development.

Secondly, a comprehensive investigation should be conducted in response to the existing algae plants and its distribution rules in the lake area, and on this basis, salt -resistant and salt -add algae plants are selected to provide genetic resources for the use of algae resources of salt ponds; Salt crops, develop salt pond agriculture.

Thirdly, some salt pond algae itself has high nutritional value, which can develop microalgae breeding through artificial culture and directly create economic benefits. For example, Du's algae's β-carotene weighing weight can be as high as 8%to 10%, and it is rich in glycerin, protein, fatty acids, chlorophyll, and resky oil. It can be widely used in the medicine, food and cosmetics industries. Economic algae. Spirulina is a wide -salt algae. It can grow in high salt water, high photosynthesis, and 20 times higher than soybean -produced protein than soybean. It also has anti -aging effects; Mu's horn coat algae oil content is very high, which is of great significance in the development of microalgae energy.
