Method for regulating seasonal aspect and species composition of ground cover community by adding coal ash into airport matrix

Abstract

The invention discloses a method for regulating a seasonal aspect and a species composition of a ground cover community by adding coal ash into an airport matrix. The method comprises the steps: firstly, mowing plant covers in a regulatory region, then, turning soil in the region according to the depth of 20cm, and ploughing the soil once; respectively spreading 2.5t of coal ash, 1.67t of coal ashand 0.83t of coal ash into an experimental region of the regulatory region according to a sample plot with the length being 6.7m and the width being 15m, uniformly mixing the coal ashes with the ploughed soil, and carrying out filling to make the plant covers in the regulatory region in a natural growth state; and finishing the filling of a regulatory matrix, and then, carrying out investigationtwice every month. The method aims at controlling food sources of birds and changing the habitat and breeding environments of the birds on aspects of plants, reducing the diversity of species and realizing plant simplification, so that the species and amount of the birds are reduced, the hidden safety hazards of the birds to an airport are reduced, a theoretical basis is provided for operation management of a plant community in the airport, and meanwhile, a scientific basis is provided for the prevention work of bird strike in the airport.

Description

technical field [0001] The invention belongs to the technical field of ecological security, and relates to a method for adding fly ash to an airport substrate to control the seasonal phase and species composition of ground cover communities. Background technique [0002] Plant community (Plant community) is a regular combination of plants in a certain area, in which there is a certain ecological relationship between plants and between plants and the environment. The result of the combination can form a certain appearance and structure, a certain Plant species composition, and can form the plant environment within the community. Due to the different climatic conditions and habitat conditions, different plant communities are formed, and each community has its unique types, layers, structures and appearances. The hierarchical structure of the community is complex, and the species are also rich, such as tropical rainforest; but in the harsh and harsh conditions of the habitat, ...

Problems solved by technology

As a part of the airport ecosystem, the ground cover plant community not only beautifies the environment, regulates the micro-ecological climate in the airport, but also has the functions of absorbing water and melting snow, but it also has shortcomings: insects, rodents, hares and a lot of soil The organisms provide grass seeds and habitats, thereby attracting various birds, especially raptors, pigeons, shorebirds, gulls, etc., to feed and rest at the airport

However, there is no research report on the use of fly ash to regulate the airport vegetation community.
