natural resources

Wetland resources

According to the classification system of the Convention on wetlands and the classification standards of the national technical regulations for wetland resources investigation and monitoring, the wetlands in Yanming Lake Nature Reserve can be divided into eight types, which belong to the natural and artificial wetland systems. There are three categories and six types of natural wetland: permanent River wetland, flood land, permanent freshwater lake wetland, forest swamp, shrub swamp and herb swamp; there are two types of constructed wetland: paddy field and reservoir. Compared with the wetland types in Jilin Province, the wetland type accounts for 57.5% of Jilin Province, which is one of the regions with rich wetland resources.

The wetland area is 18905 hectares, accounting for 35.0% of the total area. Among them, the natural wetland area is 17357 hectares, accounting for 91.8% of the wetland area, and the constructed wetland area is 1548 hectares, accounting for 8.2% of the wetland area.

Among the natural wetlands, the largest area is forest swamp with an area of 8100 hectares, accounting for 46.7% of the natural wetland area; the second is river wetland with an area of 2800 hectares, accounting for 16.1% of the natural wetland area; the third is herb swamp with an area of 2450 hectares, accounting for 14.1% of the natural wetland area; and the flooding area is 1600 hectares The results show that the area of wetland is 1 545 hectares, accounting for 9.2% of the natural wetland area; the area of shrub swamp is 1 545 hectares, accounting for 8.9% of the natural wetland area; the area of Lake wetland is the smallest, accounting for 862 hectares, accounting for 5.0% of the natural wetland area.

The area of constructed wetland in this area is mainly reservoir with an area of 895 hectares, accounting for 57.8% of the total area of constructed wetland in this area, followed by paddy field with an area of 653 hectares, accounting for 42.2% of the total area of constructed wetland in this area.

Forest swamp

The forest swamp is dominated by Betula platyphylla - Carex angustifolia swamp, and the shrub swamp is dominated by Betula platyphylla Carex swamp and Carex angustifolia Carex swamp. The main types of herbaceous swamps in this area are felt swamp, Carex angustifolia swamp, Phragmites australis swamp and miscellaneous grass swamp. Felt swamp is the main type of herbaceous swamp in this area, which is widely distributed. There are Carex floating raft swamp and Carex tatau swamp with large area. Carex floating raft swamp is the most typical swamp type in Jilin Province, which enriches the heterogeneity of the Ming waters and provides excellent space conditions for waterfowl habitat. Due to the covering of the floating mat, the temperature of the river water body under the "Floating Raft" is reduced, which creates a suitable water environment for the spawning and feeding of cold water fishes.

Management status

The reserve has set up a Reserve Management Bureau with six functional departments and three protection management stations, Dashan, Dagou and Sihaidian. Dunhua City has formulated "Jilin Yanming Lake Nature Reserve Management Measures", "provisions on grazing prohibition in key protected wetlands" and "ten prohibitions for residents in the reserve" and other normative management regulations and documents. Over the past few years, we have successfully demolished an individual gas station in the reserve, cracked down on more than 20 cases of destruction of forest land, occupation of wetlands, and indiscriminate hunting and killing of wild animals, and released more than 30 wild animals. As of 2009, 1500 hectares of cropland, 300 hectares of grass and 70 hectares of wet land have been returned to the nature reserve, and 2500 hectares of forest have been planted under the forest canopy. The forest coverage in the nature reserve has increased from 49 and 5% in 2000
