摘要
借鉴景观生态学的方法,利用遥感技术对湖南某露天开采矿区生态空间结构进行分析评价,突破过往露天采矿环评项目中生态环境影响评价以定性为主的评价方式。针对露天开采对生态系统扰动面积大、地表生态景观变化大的特点,将景观生态学的评价方法融入生态环境影响评价中,以遥感技术作为载体对项目评价区景观整体性和多样性在一定程度进行了定量评价,探讨了景观生态学评价的方法在露天矿开采项目的生态环境影响评价中的可行性和适宜性,结果显示该方法对于露天矿项目的生态环境评价有较好的适应性。
The landscape ecology method and remote sensing technology were used to analyze and evaluate the ecological spatial structure of an open-pit mining area in Hunan,breaking through the qualitative evaluation method of ecological environment impact assessment in the past open-pit mining environmental assessment project.According to the characteristics of large disturbance area of ecosystem and large change of surface ecological landscape caused by open-pit mining,the evaluation method of landscape ecology is integrated into the ecological environment impact assessment,and the landscape integrity and diversity of the project evaluation area are quantitatively evaluated to a certain extent with remote sensing technology as the carrier.The feasibility and suitability of landscape ecological evaluation method in the ecological environment impact assessment of open-pit mining project are discussed.The results show that this method has good adaptability to the ecological environment assessment of open-pit mining project.
