Based on its current conditions, ecological restoration, river management, and vitality infusion are carried out. The first phase covers a total length of 4.43km, a total research area of 1.63 million square meters, and a design area of 1.23 million square meters. The project aims to establish environmental resilience through extensive soil improvement, ecological planting, forest protection, ensuring water quality, wetland restoration, and habitat creation.
