Embodiment 1

[0028] A method for improving plant diversity in the lakeside zone, the method comprising the following steps:

[0029] (1) Select lakes or reservoirs with 3 species or less of dominant species in the lakeside zone, and the dominance degree of the dominant species is over 95%;

[0030] (2) Select an area where the dominance degree of the dominant species is over 95% and the area exceeds 5,000 square meters, and divide the area into several patches, each of which can be planted with 1,000 plants of a new species that need to be planted , each plaque is evenly distributed in this area, and the sum of all plaque areas is 30% of the total area of ​​this area;

[0031] (3) Use hard materials to isolate each patch from other places in the area. The isolation requirements are: 300 mm below the bottom mud and 200 mm above the bottom mud;

[0032] (4) When the dominant population plants in the lakeside zone grow to 200-400 mm in spring, mow the dominant population plants in the patch ...

[0045] A method for improving plant diversity in the lakeside zone, the method comprising the following steps:

[0046] (1) Select lakes or reservoirs with 3 species or less of dominant species in the lakeside zone, and the dominance degree of the dominant species is over 95%;

[0047] (2) Select an area where the dominance degree of the dominant species is over 95% and the area exceeds 5,000 square meters, and divide the area into several patches, each of which can be planted with 3,000 plants of a new species that need to be planted , each plaque is evenly distributed in this area, and the sum of all plaque areas is 30%-40% of the total area of ​​this area;

[0048](3) Use hard materials to isolate each patch from other places in the area. The isolation requirements are: 300 mm below the bottom mud and 200 mm above the bottom mud;

[0049] (4) When the dominant population plants in the lakeside zone grow to 400 mm in spring, the dominant population plants in the patch shoul...

Abstract

The invention discloses a method for improving the diversity of plants in a lakeside zone and relates to the diversity of plants in the lakeside zone. The method adopts coexisting ways of dominant species control, proper bottom sediment disturbance and large emergent aquatic plant patch mosaic in the lakeside zone. On one hand, the method properly controls dominant species to prevent the dominant species from being developed without limitation. On the other hand, the germination of the original potential non-dominant species is promoted. Beside, by blazing relatively independent areas among the dominant species, new species are directly planted. The method provided by the invention has the advantages that the proper living spaces are provided for the potential species and the new planted species, and the diversity of the plant species in the lakeside zone is improved simply, conveniently and effectively at low cost.

Description

technical field [0001] The invention relates to the diversity of plants in the lakeside zone, more specifically to a method for improving the plant diversity in water-land interlaced areas such as the lakeside zone of freshwater lakes and the shoreline zone of reservoirs. Background technique [0002] Plant diversity refers to the diversification of all forms, levels, and combinations formed by plants and their environments, that is, the diversity of plant species, genetic diversity, plant ecological habits, and ecosystem diversity. The plant diversity referred to in the present invention refers to the diversity of plants at the species level, that is, the diversification of species in a region. Species diversity is the basis for community diversity and ecosystem stability, and is also the basic premise for realizing ecosystem functions.
