At present, many restoration studies often ignore this feature and do not consider the combined effects of various systems, which limits the self-purification ability of rivers to a certain extent.

Embodiment Construction

[0019] Below in conjunction with accompanying drawing, technical solution of the present invention is further described:

[0020] The riparian vegetation belt system is sequentially arranged with aquatic or wet plants and shrubs 13, arbors 14 and economical shrubs 15 from near the water body of the river to both sides. Among them, the aquatic or wet plants and shrubs on the left bank 13 are reeds, cattails, calamus, wild rice, sedge, Yujiuhua, water sedge, Alisma, wormwood, willow, willow, and willow Combination, its bandwidth gradually decreases from upstream to downstream, with an average width of 16 m; the right bank is wide in the middle, narrow at both ends, with an average width of 10 m; arbor 14 is planted with arbor 14 at a ratio of 1:2, with a row spacing of 3 m×3 m. For Amorpha fruticosa and Populus microphylla, one row is planted on the left bank, two rows of Amorpha fruticosa and one row of Populus smallleaf are planted on the right bank, and Amorpha fruticosa is p...

Abstract

The invention belongs to the technical field of an environment protection technology, and particularly relates to a method for repairing the water quality of river based on a system coupling mode. According to the method, a river bank vegetation belt system, a multifunctional pond system and a riverway bottomland micro-landform transforming system can be organically coupled with one another, so that a coupling match system can be formed. Compared with a single subsystem, the coupling match system is more complex in inner tissue and more reasonable in structure, and has the functions of strengthening the whole function of the system and amplifying the whole benefit of the system; and the water quality of the river, the structure of a river ecosystem, the quality of the biological habitat and the whole current situation of the biological environment can be effectively improved, and the physical, chemical and biological integrity of the river ecosystem can be enhanced, so that the methodis a river repairing mode 'which is near to the nature, multifunctional, high in benefit and sustainable'. The water resource can be sufficiently used, the economic benefit can be increased, and the contradiction between the environmental protection and the economic growth in the wide rural area can be effectively remitted.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a method for restoring river water quality based on a system coupling mode. Background technique [0002] Pollution is one of the important causes of damage to river ecosystems. At present, with the emphasis on the control of point source pollution and the improvement of governance capacity in our country, non-point source pollution has become an important factor affecting the quality of water environment. Especially in the vast rural areas, in order to survive, people wantonly reclaim the beaches on both sides of the river to engage in agricultural production activities; in order to increase economic income and gradually increase the investment in agricultural production, unused pesticides, herbicides, and nitrogen and phosphorus nutrients are scattered on the ground surface. The runoff enters the river and pollutes the water quality. In order to b...
