金安桥水电站废弃地植被恢复情况研究

Study on the Recovery of Abandoned Land Vegetation of Jin'anqiao Hydropower Station

植被恢复程度直接影响废弃地、弃渣场水土流失程度。为了加快水电站废弃地、弃渣场的生态恢复速度,以金安桥水电站为例,开展废弃地植被调查,分析植被恢复情况,对比植被的多度、频度、盖度及重要值,分析渣场自然恢复程度,为水电站工程及类似开发建设项目废弃地植被自然恢复提供理论基础,为水电站工程弃渣场分类治理提供依据,为水电站开发建设单位减少成本投资,对治理类似废弃地具有重要的指导意义。

The degree of vegetation restoration would have the direct impact on the abandoned farm land and spoil. In order to accelerate the ecological restoration speed at the abandoned land and the spoil field of hydropower station, taking the Jin＇anqiao hydropower as the example, it conducted the survey of the vegetation at the abandoned land, analyzing the vegetation recovery, comprising the vegetation abundance, frequency, coverage and importance value, analyzing the residue field degree of natural recovery, so as to provide the basis for the classified control of the abandoned spoil field at the hydropower station and for the reduction of the cost investment of the hydropower development agencies. It also has the important guiding significance for management of the similar spoil fields.
