Title: The Ecological Responses of Plant Community to Iron Mine Exploitation——Taking Dacibei Iron Mine as an Example
Abstract: The ecological responses of plant community to iron mine exploitation and the diversity of plant community under different disturbance intensity were investigated by using the richness index R,Shannon-Weiner index H′,Simpson indexλ,and evenness index E1.The results showed that the 32 sample plots were classified into 7 community types based on the field survey and classification principle and system of Chinese Vegetation,which were the main types of the plant community of different function areas in iron mine.According to the value of Shannon-Weiner index,the order of the species diversity of different function areas was in the following: Wutai Mountain Nature Reserve bufferThe valley outside the mineResource integration boundariesThe west of the mineThe east of the mineThe highway sidePowder storageSelection coal fieldTailings reservoirCrushing fieldExploitation area,which eflected the disturbance intensity to the surrounding environment.Simpson index could reflect the status and the function of dominant species in the plant community.
