This project is located within the Sanyang Wetland of Wenzhou Eco-Park and falls under the category of upgrade and renovation projects. Its primary objective is to systematically address critical environmental issues in the Sanyang Wetland, such as insufficient hydrodynamics, unstable water quality, and poor aquatic ecosystems. The project aims to restore the wetland's water resources, water environment, and aquatic ecology, ensuring that water quality at key monitoring sections meets regulatory standards while improving overall water quality across the entire area. The successful implementation of this project is of great significance for enhancing the scenic area's functionality and strengthening efforts to protect the Sanyang Wetland's delicate ecological balance. As part of this initiative, a total of 18 river channels have undergone dredging, covering a combined length of approximately 13.65 km. The total designed volume of dredged material amounts to 431,800 cubic meters.

Chongming North Coastal Wetland *Spartina alterniflora* Integrated Control Project

The project is located on the tidal flat area outside the seawall along the line stretching from the Chongqi Bridge to Liuyi Port in Chongming District, Shanghai. It begins in the west at the Chongqi Bridge, extends eastward to Liuyi Port, and is bounded to the south by the main seawall and to the north by the boundary between Shanghai and Jiangsu Province. The proposed use of marine resources involves temporary cofferdams. The selected site and intended use of marine resources for this project comply with the requirements of marine functional zoning. Specifically, the type of marine use falls under "Other Special Marine Uses" within the category of "Special Marine Uses," while the method of marine utilization will involve "Non-Permeable Structures." Our bureau has approved, in principle, the project’s proposed marine site and purpose, provided that the total marine area used remains within 150.0482 hectares.

Dongying Port Guangli Port Area Passenger-Roll-on/Roll-off Berth Area and Supporting Service Area Land Formation Project

The Dongying Port Area is located along the northeastern coast of Dongying City, enclosed by north and south sandbreak dikes that run diagonally from northeast to southwest. The northern sandbreak dike features a rubble-mound breakwater structure, doubling as both a main port access road and operational platform. In 2009, the port extended its infrastructure by adding a 5,220-meter-long trestle-type approach embankment extending northeastward from the existing 1,800-meter-long rubble-mound breakwater. This expansion resulted in the completion and commissioning of two 30,000-ton-class bulk and general cargo berths on trestles—though one of these berths was later converted into an oil-product berth in 2010. Subsequently, the trestle was further extended approximately 1.4 nautical miles to the northeast, culminating in the construction of a new 50,000-ton-class terminal at its tip.

Jinyi Railway

The newly constructed Yiwu–Jinhua Railway begins at the Hangzhou-Wenzhou yard of Yiwu Station, with its left and right tracks diverging from there. The left track crosses over the mainline of the existing Hangzhou-Wenzhou Railway before running parallel to the right track into the Wufengshan Tunnel. After exiting the tunnel, the entire line closely follows the northern side of the Shanghai-Kunming High-Speed Railway. In the Yiwu section, the railway passes beneath the Hangzhou-Wenzhou Railway twice and intersects with urban roads twice—once under Xuefeng West Road and once over Dongxiao Highway. Near Donghua Street in the Jinyi Metropolitan New Area, a new Jinyi Station is established, seamlessly connecting with the under-construction Jinyi East Rail Transit Station on Donghua Street for easy transfers. Finally, just east of Tangya Station, the railway crosses over the Shanghai-Kunming High-Speed Railway and merges directly into the existing Shanghai-Kunming Railway line.
