Example Embodiment

[0035] Example 1

[0036] Select a certain area in Pudong, Shanghai to simulate natural plant communities to improve plant diversity greening practices: including investigation and evaluation of natural native plant communities, community selection and optimization, seedling breeding and production, project restoration implementation and management, etc.

[0037] A. Current status and historical survey of natural native plant communities in this area: Through background survey or literature survey of the regional vegetation, determine the historical and current distribution of zonal vegetation (dominant vegetation) in this area. Investigate the current vegetation, choose a sample area of ​​400m 2 (20m×20m), including trees (100m 2 ), shrubs (25m 2 ), grass (4m 2 ) to record species composition, species height, DBH, density, richness, life form, etc. of trees and shrubs.

[0038] B. Evaluation and selection of native plant communities: On the basis of historical and current...

Abstract

The invention belongs to a forest, greening and ecological restoration field and relates to a greening method for increasing plant diversity by simulating a natural plant community. The method comprises steps of: investigating the present situation and history of natural and local plant communities in a city or an area; evaluating and selecting natural and local plant communities; optimizing the selected natural and local plant communities; breeding seedlings of the natural and local plants; applying greening projects which simulate the natural and local plant communities; and subsequently optimizing and evaluating simulative natural and local plant communities and the projects. Utilizing the multi-layer plant community characteristics (multi-layer, multi-structure, multi-function) of the natural and local plant communities, the invention establishes close-natural plant communities which can fully utilize space resources, adapt to local environments and form stable and long-term coexistence; the invention can achieve a large green quantity per unit space, good ecological benefits and powerful ecological functions, substantially increase biological diversity of urban greenland, improve landscape functions, show regional characteristics and reduce maintenance costs.

Description

technical field [0001] The invention belongs to the field of forest, greening and ecological restoration, and in particular relates to a greening method for simulating natural plant communities and increasing plant diversity. Background technique [0002] Urban plant diversity is an important basis for improving urban ecological environment, enriching urban landscape, highlighting regional characteristics, and promoting sustainable development of regional society, economy, and environment, and is an important part of biodiversity conservation. In recent years, my country's urban ecological environment and landscaping construction have achieved rapid development, but there are widespread phenomena such as single plant species, poor ecological function of the community, monotonous landscape, and neglect of native plants, which lead to "a thousand green faces". The core problem is the plant Diversity applications are woefully inadequate. [0003] Biodiversity protection is of g...
