Study On Artificial Interference Region Vegetation Ecological Restoration Of East Lake Tunnel Engineering Major

In the process of urban construction,destroy the environment of vegetation growth,vegetation ecological reconstruction of degraded habitats become repair one of the important problems need to solve urgently.Ecological restoration is to restore the damaged ecological system function and related physical,chemical and biological characteristics.Its essence is to restore the function of system and make the system achieve self sustaining state.In a certain sense,is to make the damage to the ecosystem structure and function of maximum close to the damaged before.For specific damaged ecosystems,find out the current environmental conditions of restrictive factors,according to the principle of ecological engineering,the implementation of population form or reconstruction,to restore its original biodiversity,to possess a self-sustaining and self-adjusting ability.Terrestrial vegetation ecological restoration is not just the ground vegetation reconstruction,but also affect the survival of the many kinds of ecological factors of ecological restoration and collaborative development.This study combined with artificial interference characteristics,east lake channel engineering major terrestrial vegetation status quo,in order to "habitat reconstruction" strategy to determine appropriate vegetation restoration technology,containing the zonal vegetation construction,soil seed bank and planting soil matrix repair three aspects,emphasizing the ground vegetation and soil seed Banks and the coupling relation of soil matrix repair measures for damage to vegetation growth,build appropriate site conditions and ecological environment,promote the optimization and succession of vegetation community,improve the effect of the vegetation landscape restoration.Aquatic plants is physically attached to the aquatic environment,and at least part of the reproductive cycle in water or on the surface of the water plant groups.Aquatic plants to the eutrophication of water body has good repair effect,it by its own growth metabolism can be a lot of absorption of nitrogen,phosphorus and other nutrients,water adsorption suspended particulate matter and inhibit the growth of algae low,purify water,improve water ecological environment,promote the degradation of ecosystem restoration of the water body.Recovery of a large aquatic vegetation and its related technology is the key tothe eutrophication of lake ecological restoration technology.There are:(1)bottom repair technology;(2)biological control technology;(3)the aquatic vegetation ecological restoration technology;(4)the ecological floating island technology.Through suitable vegetation ecological restoration technology,in order to fully repair the east lake channel construction land,lakeshore zone around the area of vegetation and ecological environment,aquatic plants and landscape coordination configuration of spatial configuration and species,to achieve the optimal and succession of vegetation,the construction of the east lake scenic area reduced to minimum the influence of the natural landscape,artificial interference for severe area of vegetation restoration and reconstruction to provide technical support and decision-making reference.
