example 1

[0036] Example 1: Plant collocation pattern in plain and hilly areas

[0037] (1) Within the scope of the Funiu Mountain Nature Reserve, low-altitude areas (700m-1200m), look for areas with relatively little human interference, relatively intact forest ecosystems, and relatively flat terrain.

[0038] (2) Conduct community ecology surveys in the region: Set up sample plots and quadrats in different areas of the forest ecosystem, and conduct plant surveys in the quadrats. The survey indicators include: coverage of the arbor layer, species, number of individuals, tree Height, branch height, crown height, crown width, base diameter, DBH, etc.; shrub layer coverage, species, number of individuals, tree height, crown width, base diameter; herb layer coverage, species, number of individuals, height , crown width, base diameter (cluster diameter), and also investigate the age structure of the community and the degree of human influence.

Abstract

The invention relates to a dominant indigenous plant functional group based three-dimensional plant collocation pattern of trees, shrubs and herbs. The method is to fine a relatively complete and primitive forest ecosystem closest to the area of which vegetation needs to be recovered or reconstructed. A community ecology survey is carried out in the system to respectively determine the dominant species at tree layers, shrub layers and herb layers; by taking X2 test as bases, association coefficient (AC) can be combined with co-occurrence percentage (PC) to respectively determine the associativity between the dominant species at each layer; and plant functional groups can be divided by taking the dominant species as a main part. On this basis, the dominant species at the tree layers, the shrub layers and the herb layers can be integrated; the representative plants in the plant functional groups at each layer can be taken as a whole; and through interspecies association analysis, the functional groups including the plants of the tree layers, the shrub layers and the herb layers can be divided. Therefore, the recovery of three-dimensional plant collocation planting can be carried outon the areas of which vegetation needs to be recovered or reconstructed.

Description

technical field [0001] The invention belongs to the fields of ecological protection, ecological system vegetation restoration and landscape garden plant configuration, and relates to a three-dimensional plant collocation pattern of trees, shrubs and grasses based on functional groups of dominant native plants. Background technique [0002] In order to protect the ecological environment, our country has carried out a lot of afforestation work, whether it is natural forest protection projects, returning farmland to forests and grassland projects, and national reserve forest projects, or urban and rural ecological protection, landscape garden green space construction, when choosing plants , there is a certain unscientific nature. The specific manifestations are: (1) The plant configuration is very random, and most of them only consider the aesthetic effect and the functional characteristics of some plants, lacking the overall scientific basis; (2) The plant configuration does n...
