Construction technique for beach saline land landscape water aquatic plant system

Abstract

The invention discloses a construction technique for water plant system of scenic water in coastal saline-alkali area. The method aims at the characteristics such as high salt content in the soil and the water in scenic riverways in coastal saline-alkali area and utilizes highly saline reuse water washing salinity technique and salt-proof techniques such as raw soil mixed with sand and salt discharge subdrain, etc. to reduce the salt content of the soil and water of the riverway. Meanwhile, in respects of increasing the ornamental performance and strengthening the purificatory function, water pioneer plants and land pioneer plants suitable for the ecological restoration of the scenic riverways in coastal saline-alkali area are selected preferably, and are subject to domestication and optimal distribution, thus the water plant system of scenic water in coastal saline-alkali area is successfully constructed, thereby improving the environmental scenery effectively and restoring the quality of the water gradually.

Description

technical field [0001] The invention relates to the construction of an aquatic plant system for a coastal saline-alkali land landscape water body, and belongs to the technical field of landscape river water environment ecological restoration. Background technique [0002] At home and abroad, municipal landscape rivers and lakes play a very important role in maintaining the overall ecological environment of the city. In order to prevent the water quality from deteriorating, on the one hand, the indicators of nutrients such as nitrogen and phosphorus discharged into the landscape water are strictly limited; For the polluted landscape water body, effective water purification measures should be taken to improve the water quality and ecological environment of the landscape water body. For this, the environmental restoration techniques usually used include: chemical methods, physical methods and ecological methods. Judging from the development trends of the above three technologie...

Problems solved by technology

In recent years, scientists at home and abroad have conducted a lot of research on the restoration of river courses and lake water ecosystems and the ecological restoration of saline-alkali soils, and have made some progress, but they have also encountered many difficulties. The reason is that on the one hand, salt The cultivation of raw plants is difficult and takes a long time. Even if the aquatic plants are restored, a stable and effective water quality maintenance and purification system cannot be formed.

This is mainly because the settlement of aquatic plants under saline-alkaline conditions is very difficult, and most of the work focuses on the survival of a single or several plants, and less consideration is given to the environmental prerequisites required to restore a stable aquatic vegetation system
