ecological protection and landscape planning of Zhangze Lake National Urban Wetland Park in Changzhi City

I. Planning scope

On the basis of the original Zhangze Lake National Wetland Park (58.72 square kilometers), combined with the surrounding planning road network, it is appropriately expanded and adjusted, and the overall planning area is 63.24 square kilometers.

second, the planning concept

(1) giving priority to protection-protecting the natural ecological habitat in the lake area

The primary premise of the wetland park is the protection and restoration of the ecological environment, and at the same time, it has the dual functions of tourist attractions and wet biological conservation habitats, reducing the impact of people's activities on the wetland, and realizing the design concept of harmonious life between man and nature through rational functional layout and the creation of wetland habitats.

(2) Limit development-pay equal attention to protection and development

On the basis of the original ecological environment protection, build and improve the overall environmental quality, rationally develop and utilize it, and its construction land will not encroach on the ecological greening network framework determined by the wetland park, so that environmental protection and urban construction will develop harmoniously.

(3) Creating Features —— Exhibiting the charm of Shangdang to promote humanistic harmony

Based on the creation of the ecological environment of wetland lakes, Shangdang Water Town is featured, and through the architectural features, landscape sketches, bridges and water systems of theme parks, the scenic spots with charm in southeast Shanxi are reflected, and the "water town garden" in the north is created.

III. Planning Objectives and Positioning

(I) Planning Objectives

V. Plan

Special plan for comprehensive management of water environment of Zhangze Lake National Urban Wetland Park in Changzhi City

I. Analysis of water source and quantity

The average annual runoff of Zhangze Reservoir in the south of Zhuozhang River is 265 million m3, of which the upstream reservoirs of Zhangze Reservoir control 41 million m3 and the interval of Zhangze Reservoir is 25 million m3. There are four fan-shaped main tributaries in the upper reaches of the water source of the Wetland Park, with Jiang River and Lanshui River on the left bank and Shizi River and Taoqinghe River on the right bank.

ii. analysis of pollution sources

the pollution sources in wetland parks are divided into internal import and external import. Internal inflow pollution sources are: industrial sewage around wetlands, agricultural and aquaculture sewage and domestic sewage discharge in villages and towns. The external pollution sources are: upstream basin inflow, urban sewage discharge and initial rainwater pollution. The main pollutants are mainly CODMn, ammonia nitrogen and total phosphorus.

III. Planning objective

Short-term objective (by 2121): The water body in the upper reaches of the wetland completely meets the requirements of surface water class V. The water quality of wetlands has gradually improved fundamentally, and the problem of eutrophication has been fundamentally reversed, reaching the level of mild eutrophication. The water landscape and ecology have been restored, and the surrounding environmental quality has been significantly improved

Mid-term goal (by 2125): the water body in the upper reaches of the wetland basically meets the requirements of surface water class IV. The water quality of the wetland has been fundamentally improved, basically reaching the requirements of Class IV surface water, and the problem of wetland eutrophication has been fundamentally controlled, and eutrophication has basically not occurred.

Long-term goal (before 2135): The water quality of wetlands will continue to improve and basically meet the requirements of Class III surface water. The quality of water environment can be maintained for a long time, and the harmony between man and environment can be achieved.

iv. control measures

(1) ecological interception buffer zone for non-point source pollution

carry out "source-process-end" pollution control for non-point source pollution generated in wetland experience area and farmland reclamation area inside wetland. Set up three lines of defense and implement the whole basin restoration, including water conservation forest project, bank protection forest project and clean water project.

(II) Restoration of River Shoreline

According to the construction requirements of "five lakes and six parks" in urban wetland park, various forms of ecological revetment can be designed and constructed in the wetland according to different functional blocks, water purification needs and habitat construction intentions, and it is suggested to keep natural original revetment in non-human activity areas.

(III) Sediment dredging project

The sediment pollution in the upper reaches of the wetland is serious, and many indicators such as ammonia nitrogen and total phosphorus exceed the standard, which has become a potential dangerous pollution source of the water body and needs to be dredged. The dredging project in the upstream of the wetland covers the water inlet area of the south source of Zhuozhang River and the ecological conservation area, which should be adjusted in combination with the development of the wetland park. The dredging amount is about 651,111 m3

(IV) Pollution prevention and ecological degradation technology

The water body in the upstream of the wetland is seriously polluted. In order to quickly improve the water quality and eliminate the black odor, measures of pollution prevention and ecological degradation should be taken. Specifically, it includes nano-oxygenation technology, multiphase microfiltration water purification system, ecological base, ecological reactor, microbial online factory and so on.

(5) upstream water distribution project of Zhuozhang Nanyuan

The reclaimed water system of the sewage treatment plant in Changzhi main city has been running normally. At present, some reclaimed water is used for circulating water in power plants and a small amount of industrial enterprises, and the rest is discharged into Shizi River. It is suggested that the location of reclaimed water should be adjusted and connected to the upper reaches of the south source of Zhuozhang, which can not only improve the water quality by using its environmental capacity, but also provide it with reliable water source.

(6) Construction of aquatic flora and fauna system

According to the principle of "ecological succession", the typical wet plant belt composed of trees, shrubs, marsh vegetation, emergent vegetation, floating vegetation and submerged vegetation will be gradually restored; Put zoobenthos and fish in to build an aquatic ecosystem.

How to divide the west, assuming that the Hero Street divides Changzhi into the east and the west, and the east of the West Ring Road is basically the old city. Due to the lack of open space, the new development capacity is limited, and the possibility of overall transformation is small.

The west of the West Ring Road is planned locally, which has great development potential. There are three main reasons:

1, the whole city of Changzhi is expanding, while the east has developed to the foot of Laoding Mountain, and the development area is limited;

2, there is less development in the west, especially in the west of the railway, and there are more open spaces.
