Tuohu wetland
The tourism planning of Tuohu scenic spot is an important part of the "Huaihe customs" tourism planning in Bengbu tourism master plan.
Tuo Lake is a shallow brown lake with a river depression from north to south. It starts from the northern suburb of Wuhe River in the south and reaches the entrance of Nantuo River and Beituo River between Wuhe River and Sixian County in the north, which is about 25 kilometers long. Its northern section is narrow, with the narrowest point of 0.5km from east to west, and gradually opens to the south, with the widest point of about 3.5km from east to west, and its center is located at East longitude 1 17 _ 49. The current water level is13.5m, and the lake surface is about 40 square kilometers. After the completion of Huaihong New River, its normal water level is 14.3 meters, and the lake surface is about 78 square kilometers.
95% of the waters of Tuohu Nature Reserve are located in Tuohu Township, which is under the jurisdiction of Tuohu Township. Tuohu Township is located in the northwest of Wuhe County, and the township government is 3.5 kilometers away from the county seat. Tuohu Village governs five administrative villages, including two agricultural villages and three fishing villages. The population of the township is 1.25 million, with 4959 mu of cultivated land and 6000 hectares of water surface. While developing economy, Tuohu Township pays attention to strengthening infrastructure construction. The road around the lake has been paved, the highway connecting every village has been realized, and the program-controlled exchange telephone has been opened. Farmers took a fancy to cable TV and used tap water, which fundamentally changed the backward situation of rural transportation, communication and information and created conditions for economic revitalization.
The economy is mainly composed of planting, aquaculture and township enterprises, among which aquaculture is the pillar and characteristic industry of Tuohu Lake. In 2000, the agricultural output value of workers and peasants in the township was 572.5 million yuan, of which the output value of river crabs was 6 million yuan and the per capita net income of farmers was 2,200 yuan.
Tuohu provincial nature reserve is located in the transitional climate zone of north subtropical zone and south warm temperate zone. As a small valley lake, it is typical in Huaibei Plain. The nature reserve has a flat terrain and mild climate, and has a variety of special aquatic resources with high economic value and rare waterfowl protected by the state, rich aquatic life and excellent ecological environment quality.
The nature reserve is rich in biodiversity, diverse in species and complete in aquatic ecosystem structure. A total of 39 species of fish specimens were collected from Tuohu Lake, belonging to 7 orders 14 families. There are two kinds of crabs and eight kinds of shrimps. There are 20 species of vascular plants in Tuohu Lake, belonging to 12 family. Phytoplankton * * * has 7 phyla and 68 genera; Zooplankton mainly includes protozoa 13 genera, rotifers 22 genera, cladocera 7 genera and copepods 6 genera. There are 99 species of wild animals belonging to 46 families and 2 1 order in the nature reserve. Birds account for the majority of wild animals, and there are 68 species belonging to 2 families in 13 orders, among which there are many rare birds, such as national first-class protected animals such as crane, stork, black stork and great bustard, and national second-class protected animals such as crane, mandarin duck and white-tailed owl.
The core protected area consists of the northern core protected area and the central core protected area, covering an area of 369.9 square meters, accounting for 8.8% of the total protected area. The northern core reserve is located in the northern part of the reserve, east of Modukou and south of Xiao Mo Beach, with an area of 9 1.7 m2. The water surface in this area is circuitous, the flow velocity is slow, the lake bottom is flat, the silt is deep, the organic matter is rich, and the aquatic vascular plants and phytoplankton grow well. Except that the inflow of farmland, domestic sewage and domestic garbage along the river has affected the water quality, the water quality indicators in this area are all good, and the nutritional status is medium. Because of the outstanding topography and good tidal flat and wetland resources, this area is one of the concentrated distribution areas of birds. The Central Core Reserve is located in the middle of the reserve, from Joy Chen Zui to Xiaowangzui North (including Xiaohuxin Beach), with an area of about 278.2 square meters. The lakes in this area are relatively wide and are greatly influenced by the microclimate of Tuohu Lake. In addition, the sediment quality of the lake is thick and the lake surface is full of light. These natural ecological conditions are very conducive to the reproduction of aquatic vascular plants and phytoplankton. Aquatic vascular plants in this area include POTAMOGETON microphylla, POTAMOGETON malayi, POTAMOGETON crispus, POTAMOGETON crispus, POTAMOGETON crispus, Phragmites australis, etc. Among them, POTAMOGETON microphylla is the dominant species in summer and autumn, and POTAMOGETON crispus is the dominant species in winter and spring. Phytoplankton includes silicon, green, blue, gold, dinoflagellate and gymnosperms. There are many lakes and bays in this area, and the beach vegetation and ecological environment in the land-water ecotone are well preserved. Over the years, it has been the wintering habitat and stopping place for many migratory birds and resident birds (including rare birds under special state protection).
In order to better protect the bird habitat and lake wetland ecosystem in the core area and avoid external influence and interference, a zone of about 200 meters is set aside as a buffer zone on the periphery of the core area; In order to protect the birds in Tuohu Lake, their habitats, wintering grounds, resting places during migration and food sources for birds, a zone of about 500 meters has been set aside in the waters around the core area as a buffer zone, with a land and water area of 969 square meters, accounting for 23.2% of the total area of the reserve.
