Sanlong wetland

Sanlong wetland

Sanlong wetland is located in Sanlong street, Ouhai District, Wenzhou City, Zhejiang Province, adjacent to Wenzhou Development Zone and Longwan District in the East, Chashan street and nanbaixiang street in the south, Wutian street and urban center in the northwest, with a total planning area of 13 square kilometers.

Geography

position

The rivers in the wetland are crisscross and dense as cobwebs, forming more than 160 "small islands" of different sizes and shapes. The ratio of water area to land area is 1.1:1. Boating on the water, around the island, such as exposure to the "paradise.".

resources

In the agricultural era, Sanlong water network wetland once formed a unique pastoral scenery. Sanlong is a land of fish and rice. Water crops such as water chestnut, lotus root and various kinds of fish are rarely famous in Wenzhou. Its economic benefits far exceed the mediocre agricultural production.

Development status

Ecological status

Sanlong wetland has been developed for agriculture for centuries. At present, the land area accounts for 70.9% of the total area, and the water area only accounts for 29.1% of the total area. 47% of the land area was planted citrus, 15.2% was urban construction land, and other agricultural land, abandoned land and ponds accounted for 37.8%. More than 50% of the water area is equipped with fish cage.

The regional natural vegetation and various biological species are relatively single, and the level of biodiversity is low. There are more than 150 species of higher plants recorded in the whole year, 40% of which are cultivated species, while the wild species are mainly Gramineae, Compositae, Labiatae and Polygonaceae weeds, and there are basically no wetland plants growing; there are more than 30 species of birds, more than 10 species of fish, and mainly artificial silver carp and carp. The species and quantity of other soil animals, benthos and insects are 10-30% of the natural wetland.

According to the results of the annual investigation and analysis, in addition to the air and soil quality, the regional water environment quality is seriously damaged, the overall water quality is inferior to class V, and nitrogen, phosphorus, heavy metals and other indicators seriously exceed the standard. The main pollution sources are the inflow of Wenruitang River and the discharge of domestic sewage from residents and industrial enterprises.

In conclusion, due to long-term cultivation, Sanlong wetland is a wetland ecosystem that has basically lost its original wetland properties.

The soul of the city

The protection value of Sanlong wetland far exceeds the tourism and direct economic benefits. According to the International Convention on wetlands, wetlands, together with forests and oceans, are known as the three major ecosystems in the world. They not only have rich resource value, but also have huge environmental regulation and ecological functions. For Wenzhou, Sanlong river network wetland plays an important role in providing water resources, regulating climate, conserving water resources, storing flood and preventing drought, degrading pollutants and protecting biodiversity. Planning experts believe that if Daluo mountain is the lung of Wenzhou City, Sanlong wetland is the "kidney of the city", which is an important element to meet the sustainable development of the city and one of the advantages to improve the competitiveness of the city in the future. Sanlong wetland and daluoshan park are reserved as "green heart", which will further strengthen the characteristics of "landscape city", add spirituality to Wenzhou City and provide beautiful space for people's life.

The survival of Wetland

At present, Sanlong wetland is facing the threat of industrial pollution. The river water, which used to be clear and bottoming out, has been polluted in a large area and turned red, black and smelly locally. Although 20 million yuan has been invested in dredging and pollution control in Sanlong street, the water quality of Sanlong is below grade III. The hardware electroplating, non-woven fabric industry and domestic sewage of Sanlong Street are eroding the original pure and transparent water body of Sanlong.

The more terrible threat is that the land and water are in danger of being eaten by a large number of people. Many people are eyeing the Sanyang wetland, and some departments have put forward requisition requirements. There is a threat that Sanyang wetland will be eaten by a large number of people. Sanlong wetland is only 2 km away from the new urban center, which has become the forefront of rapid urban growth. As the kidney of the city, Sanlong wetland needs to be protected. We should strengthen the protection of wetland natural ecosystem, give full play to the ecological effect of wetland, and make Sanlong wetland a tourist attraction.

Invite scholars to feel the pulse

Wenzhou Ecological Park Management Committee and Planning Bureau invited more than a dozen people from Wenzhou cultural circles to hold a seminar on Sanlong wetland culture of Wenzhou Ecological Park to discuss how to inject Wenzhou local culture into the construction of Wetland Park in phase I, so as to make human and nature coexist more harmoniously.

Within the urban area of Wenzhou, there are mountains in the city, water around the mountains, Oujiang River in the north, integrating "mountain, water, island, island, river" in one, and dense water network in the south. The city has a beautiful landscape environment. Wenzhou Ecological Park is one of the nine strategic projects in Wenzhou. We must fully consider how to realize the maximization of ecological, social and economic benefits, and how to protect the "green heart" and "green lung" of Wenzhou. It is the need of building a landscape Wenzhou City with vitality, strength and harmony.

Sanlong wetland covers an area of 13.6 square kilometers and consists of 161 islands. Sanlong wetland has dense water network, villages are arranged along the river, and folk houses are built near the water. In March of Longqi spring, lush green trees are everywhere along the river, cuckoos are singing, and flying swallows are shuttling. Recently, orange orange oranges are hanging all over the fruit trees on the island; the natural scenery is unique. Zhang Cong, Minister of the Ming Dynasty, once praised San Xun with the poem that "the setting sun goes boating along jupu, and the light Xia goes to Taoyuan". Now, according to the planning plan, Sanyang wetland has been built into an ecological park of "jupu Fangzhou, egret wild duck, water chestnut lotus root, river network family".

Relevant cultural experts expressed their opinions and a hundred schools of thought contend at the forum. Some require that Sanyang Wetland be fixed in the words of "clear, quiet and green" to pursue clean river network, tranquil spirit and greening, so as to make visitors feel the original ecological style of harmony between human and water. There are also some suggestions that we should develop less and protect more, and try our best to show tourists an original ecology of Sanlong. Some people have made specific arrangements to row by hand and step on pleasure boats, and set up electric pleasure boats to walk through the river, so as to avoid the damage of noise and machine noise to the environment.

Future planning

Recently, the revision of the regulatory detailed planning of Sanlong wetland passed the expert review and entered the stage of online pre approval publicity. With the upgrading of wetland park planning, high-quality buildings have been selected here, and the surrounding facilities are becoming more and more mature. An ecological and livable residential plate has gradually entered people's vision.

New planning creates new urban highlights

As one of the three highlight blocks in our city, the planning and construction of Sanlong Wetland Park has been attracting much attention. After revision, the planning scope of Sanlong wetland park extends to Ouhai Avenue in the north, Wenrui Avenue in the west, Zhongxing Avenue in the East, expressway in the South and Daluo mountain, with a total area of 11.66 square kilometers.

Sanlong wetland is well-known as "Venice in southern Zhejiang" for its dense water network and beautiful natural scenery. In the future, based on high-quality ecological environment, relying on history and culture, Sanlong Wetland Park will improve tourism service facilities, strengthen the interaction between tourism and various industries, and build a national wetland park integrating ecological conservation, scientific research, popular science education and leisure tourism.

From the overall spatial layout, the wetland park will adopt the structure of "one ring, one belt, two pieces and ten districts". Relying on the inner main ring road of the Wetland Park, the "one ring road" connects the functional areas in series to form a peripheral buffer zone. "One belt" is the transportation hub belt and reception service belt. Relying on nanxiandi, it radiates to both sides of the wetland. As the main east-west traffic of the park, it connects the main traffic transfer and service groups in the reception area. "Two pieces" are dynamic in the north and static in the south, dynamic for leisure, combined with the first phase of the park, focusing on wetland landscape tour, cultural display, science demonstration, etc.; static for ecological demonstration, combined with the ultimate goal of the National Wetland Park, focusing on ecological protection, science education, etc.

"Ten areas" refers to the ten functional areas of Wetland Park, including water activity area, local culture area, Wetland Demonstration Area, reception service area, science and technology exhibition area, agricultural experience area, ecological recreation area, wedding theme area, conservation and breeding area, and wetland leisure area.

According to the introduction, at present, the main ring road project of wetland phase I is expected to enter the construction site in November; the landscape project has completed the project approval and construction drawing design, and the project is divided into four sections for construction, of which section I has completed the construction bidding and entered the construction site, and other sections are planned to enter the construction site in November; the construction project has completed the architectural scheme design, and is entering the stage of preliminary design, which is expected to be completed Construction is about to start.
