Method for constructing close-to-nature ecological bank

Abstract

The invention discloses a method for constructing a close-to-nature ecological bank. According to the technical scheme, a method of constructing a basement bank, paving the bank with mixed earthworm soil, paving the bank with a soil fixation net, constructing a plant belt, cleaning phycophyta and conducting periodic maintenance is adopted, the water storage and drainage capability of the bank is improved, the problems of plant diversity and amphibian inhabiting are solved, a close-to-nature ecological environment which can be sustainably developed is formed, and the ecological bank has the purifying capability of increasing the green land area and strengthening water and soil, and is a self-adjustable ecological system. According to the method for constructing the close-to-nature ecological bank, a principle of harmonious coexistence between man and nature is abided by, the water bank is constructed through a new thought and new technology, a natural and healthy ecological cycle system can be formed, the artificial maintenance cost in the later period can be reduced, and the close-to-nature ecological bank is easy to operate and popularize.

Description

technical field [0001] The invention relates to the technical fields of restoration ecology and urban ecology, in particular to a method for constructing a near-natural ecological slope. Background technique [0002] The bank is the transition zone from land to water. The slope bank in the natural state provides a growth substrate for plants, a space for animals to inhabit and move, and plays an important role in water conservation, flood storage and drought prevention, and maintenance of biodiversity and ecological balance in the ecosystem. The goal of bank maintenance and improvement is vigorously advocated and implemented at home and abroad. The real ecological slope bank should be a complete ecosystem composed of plants, animals, microorganisms and environmental substrates, which has high biodiversity, so the exchange of materials, energy and information can continue in the water body and terrestrial ecosystem. conduct. The soil matrix supports the life process of ani...

Problems solved by technology

The existing problems are as follows. First, when constructing artificial slope bank, taking into account factors such as river flooding speed, anti-scouring capacity, and water and soil conservation, more hardened materials such as cement are used, which destroys the natural structure between water and soil, and damages the slope. The filter and purification function of the shore will lose the living conditions of animals and plants at the junction of water and land, weaken its own ecological function, and lead to a decline in its ability to resist disasters such as heavy rain and floods; secondly, considering factors such as easy construction and reduced land occupation, The slope angle tends to be vertical, which prevents animals from carrying out the necessary drinking and migration activities normally, and there is a risk of animal drowning and death; third, the vegetation artificially planted on the slope bank is mostly a single plant, the survival rate of the plant is low, and it is easy to be invaded Replaced by plants, and the maintenance cost is high, which destroys the habitat of resident animals and reduces the complexity and stability of the ecosystem; Fourth, the treatment and reconstruction of water body slopes often lack relevant information during the design and construction of actual work.
