Problems solved by technology

[0006] The construction of riverside belts is an important measure for river ecological governance and restoration, but most of the current riverside belt constructions strengthen the cement hard slope protection combined with landscaping to strengthen flood control and aesthetic functions, ignoring the ecological functions of natural riverside belts , and the selection of green plants is more about aesthetics, without more consideration of the requirements of the region and climate

Embodiment 1

[0019] The selected arbor species are walnut catalpa, Alder tomentosa, and Mandshurica mandshurica, the determined shrub species are Spiraea lanceolata, Acer japonica, and Ussuri buckthorn, and the determined herbaceous plants include barnyardgrass, Xing'an hair lotus, Yellow flower water golden phoenix. The types of aquatic plants are determined to be water lilies and calamus. Plants in the riverside zone are planted purely or mixed in the order of aquatic plants, grasses, shrubs and trees. The planting width or planting ratio of various plants is 1:5:3 :2. The slope of the planting is 3%, and the length of the planted riverside belt is 25 meters. Its interception effect on pollutants shows that the farmland drainage involved in the riverside belt area is introduced into the riverside belt, and then enters the river after being purified by the riverside belt. The monitoring results show that the removal rate of SS in this riverside zone is over 85%, and the removal rate of n...

Embodiment 2

[0021] Determine the type of arbor as one or a combination of elm, white birch, thick plum, dry willow, etc., the type of shrub as one or a combination of bark willow, pink branch willow, white river willow, red Swiss wood, and the herbaceous plants as camphor, One or a combination of Malan, celery, astilbe, hair lily, old celery, and wild pea; aquatic plants are one or a combination of water onion, wild rice, black triangular, reed, and the riverside zone The plants are planted in the order of aquatic plants, grasses, shrubs and trees in simple or mixed planting. The planting width or planting ratio of various plants is 1:5:3:2 in turn, the planting slope is 4%, and the revetment planted is Silt soft slope protection, the length of the planted riverside belt is 25 meters, and its interception effect on pollutants shows that the farmland drainage involved in the riverside belt area is introduced into the riverside belt, and then enters the river after being purified by the rive...

Embodiment 3

[0023] Select the type of arbor to be one or a combination of walnut catalpa, willow, spring elm, etc., and select shrubs to be one or a combination of willow spiraea, white river willow, pearl plum, honeysuckle, etc. One or a combination of herbaceous barnyardgrass, celery, wild soybean, celery, clover, etc., and one or a combination of aquatic plants such as water lily, cattail, sedge, polygonum, cress, etc. Plants in the riverside zone are planted purely or mixed in the order of aquatic plants, grasses, shrubs and trees. The planting width or planting ratio of various plants is 1:5:3:2 in sequence, and the planting slope is 5%. The revetments planted are sandy soft slope revetments, and the length of the planted riverside belt is 25 meters. Its interception effect on pollutants shows that the farmland drainage involved in the riverside belt area is introduced into the riverside belt, and then enters the river after being purified by the riverside belt. . The monitoring res...

Abstract

The invention determines a construction method suitable for a streamside plant structure in a northern cold region. The construction method includes the steps of: selecting a region with annual average temperature of 4-10 degrees and temperate continental climate as a respondent, and a streamside of a natural protection area with rich vegetation as a research site, determining corresponding streamside plant species, determining varieties and quantities of arbors, shrubs, herbaceous plants and aquatic plants, planting one kind of arbors, shrubs, herbaceous plants and aquatic plants at the streamside or sequentially planting the arbors, shrubs, herbaceous plants and aquatic plants at the streamside in a mixed manner; the various plants are planted at the soft river bank, which is sandy river bank or sludge river bank, according to a certain proportion and a certain gradient. Farmland drainage involved in the streamside region is introduced into the streamside, and flows into the river after being purified by the streamside. The monitoring results show that the streamside has good removal effect to SS and nitrogen and phosphorus.

Description

technical field [0001] The invention relates to a method for plant structure suitable for the riverside zone in the cold northern region, in particular to a construction method for determining the plant structure for the riverside zone suitable for the cold northern region in a near-natural manner. Background technique [0002] Riverside belt refers to various vegetation belts built along rivers, lakes, streams and valleys, including forest belts, vegetable fields or other land use types. It is one of biological soft measures and is suitable for water and soil conservation and control of non-point source pollution. The riverside belt is an important part of the small watershed ecosystem of rivers entering the lake, and it is the last barrier to protect the water environment of rivers and lakes. The complete riverside belt and embankment ecosystem can effectively control the low-pollution water entering the river, protect and improve the river water quality. [0003] Plantin...
