Construction method of amphibious plant community with water body purification function

Abstract

The invention discloses a construction method of an amphibious plant community with a water body purification function. The construction method comprises the following steps: dividing planting regions on a land-lake ecotone in a manner of being parallel to a river way; selecting amphibious plants, which have a good purification effect and a high survival rate, are amphibious and have a good landscape effect, and planting the amphibious plants into the planting regions to construct a plant community, wherein the amphibious plants are selected from more than three of bamboo reeds, iris wilsonii, cyperus altrnlifolius, reeds, cannas and lythrum salicaria; managing the plants according to growth conditions of the plants. Properties of absorbing pollutants of the plants are combined with biological properties of the different plants, and an attractive landscape is created at the same time; an amphibious plant community system is constructed by using ecological niches of the different plants, so that the effect of purifying a water body is improved; meanwhile, withered plants are harvested and external pollutants are not introduced, so that rotted plants are prevented from entering the water body, and furthermore, the content of the pollutants in the water body is reduced.

Description

technical field [0001] The invention relates to a method for building a group of artificial vegetation, in particular, the invention relates to a method for building a group of amphibious plants with the function of purifying water. Background technique [0002] With the increase of population and the acceleration of urbanization, many areas of our country are facing different degrees of environmental pollution, among which the pollution of water environment is particularly serious, which has seriously affected the daily life of the people. The means of adopting aquatic plants to purify water bodies has become a new measure. On the one hand, the planting of plants can intercept some pollutants and effectively reduce non-point source pollutants entering the water body; on the other hand, plants can reduce the content of water pollutants through their own absorption and decomposition characteristics. [0003] However, in the process of technology application, aquatic plants i...

Problems solved by technology

The present invention provides a group of artificial wetland plant communities with high removal rates of ammonia nitrogen, total nitrogen and phosphate and their applications, which are of great significance for improving river water quality, water environment and people's health. However, the emergent plants of the invention, Floating plants and submerged plants cannot grow normally under dry and dry conditions, and they are real artificial communities of aquatic plants
