Meta-Analysis of the Characteristics of Vegetation Change in Subsidence Area of Shenfuyu Coal Mining
Subsidence is one of the serious geological disasters in well mining areas.More than 20 published papers were synthesized using meta-analysis method to assess quantitatively the influences of coal mining subsidence on vegetation changes in the Shenfuyu coal mining area.The results showed that the vegetation coverage in the coal mining subsidence area declined in the early stage of collapse,but it increased and gradually exceeded the original level within two years after subsidence.The dominant species had some changes after mining subsidence,generally speaking,the number of species increased within 1～2 years after subsidence.The new plant species mostly belonged to ephemeral or ephemeroid plants after collapse interference,such as Agriophyllum squarrosum (Linn.) Moq.and Incarvillea sinensis Lam.Characteristics of vegetation change in the subsidence area also showed the important role of natural restoration in vegetation construction.The ecological construction measure that natural recovery is majorly adopted with artificial restoration complement should be carried out in the Shenfuyu mining area,even on the whole Loess Plateau.
