Focus on the Shandong chapter of the ecological restoration of the comprehensive governance of the Bohai Sea

In recent years, Shandong Province has solidly promoted the main line of the "Winning Bohai Comprehensive Governance Battle" and solidly promoted the ecological protection and restoration of the coastal belt and the maintenance of marine biological resources. During the implementation of the Bohai comprehensive governance, the Bohai Region in Shandong Province completed the renovation and restoration of 4,996 hectares of Binhai Wetland, renovated 62.82 kilometers of the shoreline, and exceeded the task.

In accordance with the goals of the Bohai Comprehensive Governance Battle Battle, the Shandong Provincial Party Committee and the Provincial Government attach great importance to the ecological restoration of the Bohai Sea and make arrangements. Cooperate with the working mechanism to form a working pattern of common governance and systematic restoration.

Return "Red Beach" landscape

The Yellow River flows into my country's only semi -closed inland sea in Dongying City, Shandong Province. The Yellow River carrying a large amount of sediment in the depression of the Bohai Sea forms a vertical plain and is a fan -shaped triangle. It is called the Yellow River Delta.

Affected by human activities, the area of ​​the National Nature Reserve and the beaches near the beach of the Yellow River Delta has continued to expand, the biological realm of the beach has changed, and the orgasm salt -ground pantragus has severely degraded, forming a large number of naked beaches, and the biodiversity of the coastal wetland is seriously threatened. The alkali ecosystem is sub -healthy.

On the tidal tidal, the distribution of alkali pans is very sensitive to the ups and downs of the terrain and the changes in high programs. The typical distribution area is often a highland surrounded by tide. Human activities such as the sea breeding blocked the normal tidal channels, causing the tidal ditch to gradually accumulate, and the water power of the beach was enhanced during the rise and falling tide, which destroyed the wetland habitat, which was one of the main reasons for the rapid degradation of the alkali wetland.

In response to the damage to the damage to the Binhai Wetland of the Yellow River Delta, Dongying City, Shandong Province carried out systemic ecological restoration, established a management agency led by the municipal government, the municipal marine development and the fishery bureau and the Kenli district government, and established the "division of labor+collaborative". Responsibility system, implement adaptive management; adhere to the role of scientific and technological support, encourage enterprises and work -based universities and scientific research units to form a consortium to cooperate to implement repair projects.

During the implementation of the Bohai Ecological Repairing Project, Dongying City was removed by the sea breeding dam on the beach coating to repair the salt -alkali pump vegetation in the area after the recovery and wet areas to promote the restoration of the natural attributes of the shoreline. Composite biological purification filter beds, ecological floating islands and biological filtration dams to build a farming pond ecological ditch purification system; by dealing with the tail water of concentrated ponds of seawater farming, effectively reduce various pollutants in the tail water Eat emissions into the sea and improve the quality of the regional ecological environment.

The repair measures improve the water power and ecological environment of the coastal wetland, and the basic habitat for salt -resistant planting such as alkali pengs has obtained natural growth. Within one year after the project was completed, measures and treatment of effective management and seedlings were restored to 1,569 hectares of salt -alkaliopiopato outside the restoration area. The "Red Beach" wetland landscape was reproduced.

Building a coastal green barrier

Weifang City, Shandong Province is located on the south bank of Laizhou Bay, Bohai. The coastal soil contains high salt, and the area of ​​strong salt staining is 381 square kilometers, accounting for 2.35%of the city's area. Comprehensive use of difficulties and other issues have always been the restrictions of the Weifang marine ecological construction.

In recent years, Weifang City has implemented a series of marine ecological restoration projects such as the Binhai Demonstration Forest Project (hereinafter referred to as the Binhai Demonstration Forest Project) of the Ecological Engineering Binhai Demonstration Forest Project (hereinafter referred to as the Binhai Demonstration Forest Project). Ecological greening problem.

The area of ​​the coastal demonstration forest project was originally an open sea area. After the construction of the reclamation project in the early days, the protection bank and the rear beach were formed. The construction of the slope -type protection embankment has destroyed the original animals and plant communities and natural landscapes of the coast, and interrupted the biological corridor and ecological buffer belt of the land and sea transition band, which leads to a single and weak ecological function.

Based on Weifang ’s many years of ecological restoration experience, the coastal demonstration forest project has planted about 700,000 salt pine (Luyi No. 1) in the salt alkali deserted beach, and 163 hectares of coastal wetlands are repaired. Through the implementation of this project, the soil saltization of the coastal demonstration forest project was reduced from 3 ‰ to 1 ‰ in the early stage of planting. The soil structure was optimized, regional vegetation was restored, and a green barrier of coastal coastal was built.

During the Bohai Comprehensive Governance Battle, Weifang's innovative financial supply method has established a diversified investment and financing mechanism for marine ecological restorations of government guidance, social participation, and market operations. At the same time, actively explore marine ecological restoration and monitoring mechanisms, and promote the incorporation of ecological restoration projects such as wetlands and coastal belts into greenhouse gas reduction projects, which provides new ideas and models for exploring the development of ecological governance and industrialization of coastal salt -alkali land.

Return to the beach natural style

The natural shoreline of the Shandong Penglai Bohai Sea is 6.4 kilometers long, mostly the sandy shoreline. The main problem in the area is that the sandy coast is eroded, the stability of the beach, and the poor environmental quality.

In response to the early human activities of this area, the coastal protective forests were destroyed, resulting in the lack of vegetation protection and severe insufficient wind and sand and sand and sand. The total area is 11.26 hectares, forming the backbin protective forest of the sandy shoreline, which enhances the wind -proof and sandwiches of the shoreline, and improves the biological diversity of vegetation along the coast. At the same time, the project cleaned the garbage along the junction of Penglai Luankou from west to Longkou Penglai, and the beach area was 23 hectares.

During the repair process, the project aims at improving the vegetation coverage and the restoration of coast vegetation, combining the sandy coastline with the combination of the sandy coastline with the local environment, and reasonably configures the type of plant, creating a multi -level coastal wetland ecosystem.

Judging from the current tracking and monitoring effect, Penglai effectively resists the impact of wind, waves, flowing, etc. through the implementation of the coastline ecological restoration project, blocking the land source pollution into the coastal belt, and enhanced the ecological function of the coastal belt, moisture and disaster reduction and mitigation. ability. Cleaning through the shoreline and shores, scientifically repair the beach, and the ecological environment along the coast and surrounding areas has been greatly improved.
