The ecological river management project on the old Shaxi Road is located on the east side of the old Shaxi Road, running north-south through Jintang Road and Xinfeng Road. The east side of the river is Tang City Junior High School. The total length of the river in the treatment area is about 600 meters, and the width of the river is about 45 meters. The slope as a whole is mounded soil, and a few parts have collapsed or slipped, which is an unstable structure and needs to be reinforced and de-risked manually. The existing vegetation of the river slope is mainly herbaceous plants with low coverage, and the middle and lower part of the slope is basically bare soil, which is very uncoordinated with the surrounding environment. Through the ecological treatment of river slope water environment syntai, the slope safety and stability, soil and water conservation and overall permanent re-greening are achieved. The successful use of planted flowering shrubs and shrubs, trees, lawns (supplemented by a small amount of flowering trees) and flexible environmental protection material plant mat technology prevented the erosion of rainwater runoff on the slope, combined with aquatic pollution-absorbing plants to purify water quality, creating a pristine ecological environment with clear water, no odor, and living space for aquatic plants and animals.
