Abstract

The invention relates to the technical field of ecological engineering, and in particular relates to a construction method suitable for ecologically restoring vegetation of a riparian zone of a sand excavation riverway in north. According to investigation of water and soil background value of the riparian zone of the sand excavation riverway in the north, aquatic (humidogene) and woody plants suitable for local environment and growth are screened out, the aquatic plants are planted in a diving zone close to riparian and sloping bank, humidogene and woody plants are planted in flood land formed by sand extraction, and then the purpose of restoring destroyed vegetation of the riparian zone is achieved. By adopting the method, the problem that the vegetation is destroyed seriously because the water quality is reduced and the self cleaning capacity is weak after river sand extraction is effectively solved, and an effective measure is provided for restoring the vegetation of the riparian zone.

Description

technical field

[0001] The invention relates to the technical field of ecological engineering, in particular to a construction method suitable for ecologically restoring vegetation in the riparian zone of a sand mining river in the north. Background technique

[0002] The riparian zone is the ecological transition zone between the terrestrial ecosystem and the aquatic ecosystem. It is a variety of plant belts built along the banks of lakes, streams and valleys. Its main purpose is to keep the water clean and intercept and filter sediment that may enter rivers and reservoirs. Organic matter, pesticides and other harmful substances. Plants in the riparian zone Plants play an important role. The physiological functions of plants are not only beneficial to the removal of pollutants, but also the interception of plants can effectively slow down the flow rate of runoff and protect the river bank. Research and practice have proved that the coastal buffer zone can effectively inter...
