Ecological prevention methods of alien invasive plants in South China forest

Abstract

The invention discloses an ecological prevention method for alien invasive plants of forests in southern China. The method comprises the following steps: firstly, removing dead tree-shrubs and / or scattered invasive plants; secondly, planting multiple local trees namely elaeocarpus balansae, olives, machilus breviflora, heteropanax fragrans, machilus chinensis, ficus virens, machilus grifsii hance, camphor trees, cinnamomum burmanni or castanea henryi on an open space in a forest community in a uniformly mixing mode, and performing stand improvement; finally, performing necessary cultivation management on trees which are newly planted in the preliminary stage of stand improvement, removing dead individuals in time, and replanting the trees. According to the method, the invasive plants, particularly sun herb, vine or shrub invasive plants, can be effectively prevented from spreading and breaking out specific to the forest community which is not damaged by the invasive plants temporarily or even a forest ecological system in which the invasive plants invade the border of the forest land to cause a threat; moreover, the diversity of plants in the forest community can be achieved, and the method has great and profound significance in the sustainable development of the forests in the southern China and the improvement of the economic benefit.

Description

technical field [0001] The invention belongs to the technical field of ecological prevention of alien invasive plants. More specifically, it relates to ecological prevention methods for invasive alien plants in South China forests. Background technique [0002] Alien invasive plants refer to certain plants that are accidentally or intentionally introduced outside the normal distribution area, colonize and endanger the biodiversity, ecological environment, habitat and human health or living environment of the invaded area. Economic globalization and the convenience of modern transportation have accelerated the spread and expansion of invasive plants. Alien invasive plants have become one of the most serious environmental problems in the world. As more and more invasive plants spread rapidly in the tropics and subtropics of my country, invasive Plants seriously endanger the structure and function of forest ecosystems. Invasive plants are very harmful to my country and have ca...

AI Technical Summary

Problems solved by technology

[0004] At present, there are few researches on the prevention of invasive plants, which mainly stay in theoretical research. In the actual prevention of invasive plants, they only stay at the stage of preventing the introduction of invasive plants (such as inspection and quarantine of alien plants, etc.), and the possibility of introducing invasive plants is high. , or already introduced or even latent ecosystems, research on preventive techniques has not been conducted

Moreover, due to the complexity of the ecological prevention of invasive plants, different plants have very complex and delicate interrelationships. Forests in different regions, different invasive plants, control and prevention methods are not repeatable, and the reference is very low.
