Abstract
The invention discloses a kind of wetland eco-reconstruction method.Wetland Communities are built by planting humidogene xylophyta in Lakeside Zone, described humidogene xylophyta includes humidogene arbor and humidogene shrub, and wherein humidogene arbor includes willow, metasequoia, middle mountain China fir, taxodium ascendens and bamboo；Humidogene shrub includes that Yunnan mouse pierces and purple willow；Planted by the way of cuttage seeding cuttage or soil ball transplantation of seedlings.Because humidogene xylophyta is perennial plant, its speed of growth is slow, biomass and increment are small, salvaged without felling every year, plant disposal pressure is small, the defect that salvaging is frequently gathered in every year by draft emergent aquactic plant group is overcome, the maintenance management cost of lake and marshland phytobiocoenose is reduced, and Lakeside Zone sediment accumulation rate can be delayed and mitigated to cause water body in lake secondary pollution hidden danger.Compared with prior art, the present invention is convenient with operation maintenance management, and maintenance cost is low, the features such as profitable on ecology, easy popularization and application, can be applied to the Ecological Restoration Project of lake lakeside beach, marsh and phytal zone.
Description
Technical field
The present invention relates to a kind of wetland eco-reconstruction method, River ecological restoration: techniques field.
Background technology
At present, the restoration of the ecosystem of the existing more engineering practice of the restoration of the ecosystem of large scale, but small range scale is rare should
With, and mostly in existing straight river corridor restoration layout designs of small range scale adopted according to the statistics in natural river bend
Determine each design parameter with empirical method, therefore, a kind of scientific and rational straight low Water Ecological Recovery engineering layout in river course of invention
Determining the problem of method has turned into the task of top priority of River ecological restoration: techniques field.
The method of linearization(-sation) river ecosystem restoration mainly has two kinds.First, being that river ecological is carried out in the range of large scale
Repair, sinuousization transformation will be carried out by the river course of linearization(-sation), be the rich and changeful habitat of biological creation.U.S. Ji Xi
The river course fallen by backfill in channelized engineering is excavated in rice (Kissimmee) river again, to form sinuous form, before returning to canalization
Nature.Britain Si Keen (Skerne) river carried out during restoration of the ecosystem sinuousization transformation, and newly-built wetland, water
The spaces such as low-lying area, shoal, enrich the physical feature in river course, improve river course diversity.Beijing turns river excavates and has got through north again
Ring water system, recovers channel planform diversity.Changchun Lianhua Shan Mountain is damaged straight parts of the river course recovery project in river course,
The sinuous form in natural imitation river, reinvents the bending shape in river as far as possible, river is gradually recovered original natural character.Its
Two, it is that river is transformed in small range scale, low Water Ecological Recovery such as is carried out to the straight river course in city.In view of city
River course space scale is limited, short-term flood control for it is main the features such as, Water Ecological Recovery building can be set low by cloth in river course, so as to
Low water season, forms the flow shape of meandering flow, and flood period does not influence river course flood again, and river oneself is recovered to a certain extent
Right state.
