Problems solved by technology

Most of the existing coastal wasteland uses physical measures and chemical measures to treat the soil before planting plants, but its environmental adaptability is weaker than that of the original coastal plants, and plants are more prone to outbreaks of diseases and insect pests in a saline-alkali environment. New plant invasion, watering, fertilization and other management and maintenance costs are high, and the improved soil fertility is not durable

Embodiment 1

[0042] Example 1 Investigation and Screening of Coastal Salt-tolerant Plants

[0043] 1. Investigation and preliminary screening of salt-tolerant plants

[0044] From 2010 to 2018, the inventor and his team conducted extensive on-the-spot surveys of trees, shrubs, and herbs based on the current vegetation status of forests, woodlands, and green areas in the coastal areas of the Pearl River Delta. A total of 96 families, 240 genera and 352 species of coastal vascular plants were investigated. Combined with the field observation and evaluation of the effects of windbreak and sand fixation before and after the arrival of the "typhoon" every year, and referring to the relevant literature on the study of plant salt-alkali tolerance, a group of coastal saline-alkali plants were initially screened out.

[0045] Among them, the preliminary screening indicators include: (1) growth status: it can grow normally in coastal saline-alkali areas, and the branches and leaves without adverse ...

Embodiment 2

[0060] For the suitable and salt-tolerant plants screened out in Example 1, the inventor and his team carried out popularization and application in more than ten coastal landscape greening projects undertaken by the company, and implemented the arbor shrub windbreak belt of the present invention in specific projects , ecological landscape belt, shrub and grass sand-fixation belt, and plant hedge construction.

[0061] 1. Project site introduction

[0062] In an ecological garden landscape construction project in Binhai Bay New District, Dongguan City undertaken by the company, due to the protection needs of the ecological landscape, it is necessary to build windbreak forests, sand-fixing grass belts and plant hedges in the coastal area 0-60m away from the coastline; among them, the ecological garden landscape The regional construction area is 29273m2 2 , construction area of ​​windbreak forest area is 27846m2 2 , the construction area of ​​coastal sand fixation area is 22198...

Abstract

The invention discloses a rapid construction method of a coastal wind prevention and sand fixation salt-tolerant landscape community, and belongs to the technical field of ecological restoration. The rapid construction method of the coastal wind prevention and sand fixation salt-tolerant landscape community comprises the following steps: site investigation; site division; soil improvement; screening of salt-tolerant plants; quickly constructing a salt-tolerant landscape community; and performing tending management. The screened salt-tolerant plants are different in shape, rich in flower leaves and high in ornamental value, the plants of different salt-tolerant grades are subjected to echelon configuration of forest belts with different functions and three-dimensional matching of trees, shrubs and grass, the purposes of wind prevention, sand fixation and salt resistance can be effectively achieved, and a good ecological landscape effect is rapidly formed; the construction method is simple, convenient and practical, tending management is simple, a coastal vegetation community stable in structure and rich in biodiversity can be formed after two years of maintenance, lasting restoration and soil improvement of the coastal saline-alkali soil are achieved, and the method is suitable for being popularized in the Pearl River Delta and even the South China coastal area.

Description

technical field [0001] The invention relates to the technical field of ecological restoration, in particular to a rapid construction method for coastal windproof, sand-fixing and salt-tolerant landscape communities. Background technique [0002] The main reasons for the formation of coastal saline-alkali land are the impact of seawater, soil transpiration, land reclamation projects, deforestation, and salt production from surrounding lakes. There are diurnal and seasonal changes, and the diversity and quantity of vegetation species are poor. Native tree species and saline-alkali-tolerant tree species grow slowly and cannot quickly form forests; the ecological environment is easily affected by typhoons, sea tides, salt dust, and salt spray. At present, there are many mature improvement measures, mainly including physical, biological, chemical and comprehensive improvement measures. Physical improvement measures adopt physical methods that are easy to implement and have simpl...
