Plant configuration method for constructing near-natural communities of surface mines and industrial abandoned sites

Abstract

The invention discloses a plant configuration method for constructing near-natural communities of surface mines and industrial abandoned sites. The method mainly comprises the following steps of: a, investigating of site conditions of a recovery area, namely investigating of natural conditions and site conditions of the recovery area; b, vegetation investigation and target plant screening; c, configuring of a target community; and d, planting mode / spray seeding. The method mainly solves the problems of high maintenance cost, single species configuration, poor landscape coordination, long natural succession period, easy vegetation degradation and the like in the existing ecological restoration engineering of surface mines and industrial waste sites, and the plant community constructed by the method has the advantages of strong adaptabilityand rapid growth on the species level, perfect structure and continuous succession on the community level, rich species and integrated functions on the ecological system level, and coordinated structure and continuous layout on the landscape level. The purpose of quickly and efficiently constructing stable near-natural plant communities on surfacemines and industrial abandoned sites can be achieved.

Description

technical field [0001] The invention belongs to the technical field of ecological restoration, and in particular relates to a plant arrangement method for constructing near-natural communities in open-pit mines and industrial waste sites. Background technique [0002] Plant configuration plays a key role in the ecological restoration of open-pit mines and industrial waste sites, especially under the concept of advocating near-natural restoration. Whether the configuration of plants is scientific and reasonable determines the short-term and long-term benefits of ecological restoration. At present, there is a lack of plant allocation technology in the ecological restoration of open-pit mines and industrial waste sites. For example, in terms of species selection, we should choose species with strong stress resistance, barrenness tolerance, and water and soil conservation functions, and the long-term adaptability of plants and the risk of invasion. Insufficient consideration; i...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a plant configuration method for the construction of near-natural communities in open-pit mines and industrial waste sites. By optimizing the design of plant species selection, species configuration mode, and planting mode, the construction investment is small, the effect is quick, and the near Natural, succession-like near-natural communities, in order to achieve the stability and sustainability of ecological restoration effects and the purpose of less or no maintenance, and solve the problem of high maintenance costs and low effects in the construction of plant communities in open-pit mines and industrial waste sites. Slow, single vegetation, easy to degrade and uncoordinated landscape
