Plant Community Structure And Growth Dynamics Of Ecological Restoration Areas In Laiwu City

Ecological Rehabilitation Project of Soil and Water Conservation in Laicheng is one of experimental projects of National Soil and Water Conservation ecological restoration project. It studies on Laiwu ecological restoration project of Soil and Water Conservation District ,Monitor and analysis the ecological, economic and social benefits after different types of ecological restoration using macro and micro combined monitoring, combined remote sensing information monitoring and artificial combined manual observations on the spot, combined long-term continuous observation and short-term temporary observation and time series sequence compare with the space observation methods. The result indicated that the ecological rehabilitation project of soil and water conservation had got obvious ecological, economic and social efficiency. The main results are as flowing:(1) Ecological restoration measures ClassificationOn the basis of Comprehensive Surveying the project area, according to the site type, the existing situation and the purpose of the restoration, at the same time combining ecological restoration project of technical features and benefits, Ecological restoration will be a pilot project for the regional ecological restoration measures divided into two major categories and four sub-categories.(2) of vegetation coverage improved, the plant cover (canopy density) to increaseThe implementation of ecological restoration measures after the plant vegetationcoverage than before to repair, in the project area of trees and grass coverage improved, by the restoration of the former 57.7 percent growth to 66.8 percent restored, an increase of 9.1%.(3) Ecological Restoration Area vegetation significantly improved the situation, biological (growth) significantly increase the amount.Ecological restoration after the ground floor of the plant root biomass and forest biomass on the ground in both than before to repair a significant raise.(4) ecological restoration area marked increase in the type of plant community Ecological restoration in the project area after a marked increase in the type of plant,plant species more abundant.(5) to promote regional ecological restoration of biodiversity increased Ecological restoration in the project area after the plant species diversity and richness improved significantly.(6) to promote the ecological restoration of natural vegetation succession.Ecological restoration, different plant communities tend to improve the ecological benefits of the direction of community succession, however, the process of succession and community structure is different.
