Description

Method for planting mangrove forest on low elevation beach

Technical Field

A method for raising the elevation of a mud flat by means of degradable ecological tubular objects, so that the method is suitable for mangrove forest planting; the method is a means for carrying out ecological restoration on the damaged and degenerated coastal zone, expanding the restoration range and improving the restoration capability.

Background

The coastal zone is a junction area where land and sea interact, and is the area with most potential and vitality for prosperity and development of human society. Ecological restoration of the coastal zone is an important means for improving the service function of the ecological system of the coastal zone and improving the marine ecological environment. I am

The country has abundant coastline resources, 1.8 km of continental coastlines and 1.4 km of island coastlines. 11 provinces and cities along the sea bear 44% of population and 55% of total domestic production value of the country by land area occupying about 13.5%, the environmental pressure is continuously increased due to large gathering of population in coastal areas and rapid development of economy, and development and utilization activities such as industrial and town expansion, port and wharf construction, sea surrounding cultivation and the like gradually occupy natural shoreline resources, so that ecological environment of the coastal areas is gradually deteriorated, ecological safety problems such as ecological environment destruction, wetland area sharp reduction, species diversity reduction, natural shoreline atrophy and the like are frequent. In order to reduce the destruction of coastal zones and avoid further ecological deterioration, the ecological restoration of the damaged and degraded coastal zones by artificial measures is an important means for improving the current status of the coastal zones. Mangrove is a population of woody plants naturally distributed in the intertidal zone of tropical and subtropical coast. The mangrove forest has the features of high biological diversity, high production capacity, high returning rate, fast decomposition speed, etc. As an important coast type, it has the ecological functions of promoting silt deposition, protecting dike and preventing wave, purifying water quality and the like, and provides important food and habitats for many animals. The mangrove forest planting in coastal zone of China is restricted by climate, substrate and other conditions, and limited by elevation of beach, so that many severely degraded beach zones can not be effectively repaired, and secondary damage to beach zones can be caused no matter the engineering waste soil is used for filling and raising or the submerged dam is stored, and the cost is high and cannot be paid. In addition, the shoal coating is polluted because of the long-term operation of bamboo-inserting type algae cultivation, purse net type fishing and the like, so that a lot of waste moso bamboos are left on the shoal coating. Therefore, a method for planting mangrove forest without lifting the beach zone by engineering is needed, waste moso bamboos can be reused, and the ecology of the beach zone can be effectively recovered.

Disclosure of Invention

The invention provides a method for raising the elevation of a beach by means of degradable ecological tubular objects so as to be suitable for planting mangrove forest on the premise of not damaging the ecology of the beach and low investment at a bank with a lower elevation.

The technical scheme adopted by the invention is as follows: according to the attached figure 1 of the specification, the degradable ecological type tubular object is mainly represented by a bamboo tube, takes waste moso bamboos as main sources, and has the following material specifications: the tail diameter is more than 6 cm, the length is divided into an upper coating part and a lower coating part by taking beach face lines as boundaries according to elevation requirements; preparing materials: cutting out the bamboo tube with corresponding length according to the elevation requirement of the beach, removing the bamboo spacer, conducting the bamboo spacer in a hollow way, splitting the top end, and marking on the boundary (beach upper line); the installation method comprises the following steps: and vertically inserting the prepared bamboo tube with the big end downwards into the beach of the pre-planted mangrove forest to the beach surface line, filling beach mud in the upper part of the bamboo tube, planting mangrove forest embryo seedlings at the top end of the upper part of the bamboo tube, and performing quincunx pile-shaped dot distribution at certain row-column intervals according to the planting density of mangrove forest planting areas or peripheral guardrails.

The beneficial effects of the invention are as follows: the method is simple in manufacturing and low in cost investment, and can raise the elevation of the beach by using easily-obtained and degradable ecological materials, so that the method is suitable for planting mangroves, more degenerated coastal zones can be restored, and the dilemma that mangroves cannot be planted easily in low-elevation areas and non-muddy beaches is solved.

Drawings

FIG. 1 is a schematic diagram of a mangrove forest monomer structure planted on a low elevation intertidal zone, wherein: the mangrove planting area monomer is composed of a degradable ecological tubular object represented by a bamboo tube and mangrove plants planted at the top end of the tubular object, wherein the tail diameter of the degradable ecological tubular object is larger than 6 cm, a bamboo partition is removed, the degradable ecological tubular object is hollow, the top end of the degradable ecological tubular object is split, the degradable ecological tubular object is divided into an upper coating part and a lower coating part by taking a beach face line as a boundary line, the upper coating part is coated with the top end of the degradable ecological tubular object to plant mangrove seedlings, and the lower coating part is integrally fixed at the mud bottom of the beach.

FIG. 2 is a schematic view of the whole mangrove forest planted on the low elevation beach: the beach upper body is integrally divided into a mangrove planting area and a peripheral guardrail, wherein the mangrove planting area and the peripheral guardrail consist of the monomers and are combined into a quincuncial pile shape at a fixed interval; wherein the peripheral guard rails are distributed at the periphery of the planting area and are arranged closely to protect the planting area.
