Landscape ecology remediation method for coastal regions

Abstract

The invention discloses a landscape ecology remediation method for coastal regions. The landscape ecology remediation method comprises the following steps: (S1) soil investigation: randomly selectingtest points in a planed to-be-remediated region, and detecting physical and chemical parameters of soil; (S2) plant screening: screening excellent, windproof and saline-alkali-tolerant plant varieties, and selecting a plant configuration mode; (S3) soil improvement; (S4) planting hole maintenance; (S5) plant plantation: spraying a root promoter to roots of the plants, and enlarging the diameter oftransplanting soil balls to be 9 times of the diameters of trunks; and (S6) windproof and anti-salt fog maintenance management. The landscape ecology remediation method has the beneficial effects that soil conditions are improved, the windproof effect is good, the planting survival rate of arbors is high, the diversity of ecological communities of the plants is enriched, the stability of an ecological system is good, the construction period is short, the cost is low, and the maintenance effect is good.

Description

Technical field [0001] The invention relates to a landscape ecological restoration method in a coastal area, belonging to the technical field of ecological restoration engineering. Background technique [0002] Guangdong Province is located in the tropics and southern subtropics, with sufficient sunlight and abundant heat, with an average annual temperature of 21-25°C and abundant rainfall. The annual rainfall on most coastal sections is 150-200mm. There are many storms in summer and autumn, and the coast is often windy. Under high temperature and rainy weather conditions, large areas of granite and sand shale are weathered rapidly, and the erosion is serious, producing a large amount of sand to be transported into rivers and oceans; under the action of ocean currents, tides and waves, many sand particles re-accumulate on the coast; After being exposed to the sea, the surface sand particles move from the outer edge of the beach to the inner edge due to the constant coastal wind ...

Problems solved by technology

However, the coastal area has a special geographical and ecological environment, which is characterized by severe typhoon and salt spray hazards, high soil salt content, and poor water and fertility retention in sandy soil. These harsh natural conditions reduce the survival rate of garden plants and affect the growth of garden plant communities. construction, becoming the bottleneck of landscaping and ecological environment construction in coastal areas

[0005] CN101161944A discloses a construction technology of aquatic plant system in seaside saline-alkali land landscape water body, including the following steps: (1) screening salt-tolerant pioneer plants, (2) washing salt in landscape rivers, salt prevention treatment, (3) establishing plant restoration areas and ( 4) Construction of aquatic plant systems in landscape rivers. This invention can be applied to the ecological restoration of landscape rivers with large soil viscosity, poor air permeability, high salinity and serious soil secondary salinization, but the present invention does not consider the effect of wind on plants. Therefore, it is not suitable for landscape ecological restoration in coastal areas with strong wind
