以抚顺西露天矿为例,基于遥感、地理信息系统和统计学等技术,分析了开采损害区景观格局的演变规律及驱动因素,并对景观格局演变速度进行了分析。通过景观形态空间格局分析方法(MSPA)与最小累计阻力模型(MCR)对西露天矿研究区生态源地进行识别,提取生态廊道,搭建生态空间格局,以空间的形式对生态敏感性和可优化地区进行展示。结果表明:2014年以林地、开采区和采矿用地等为主要土地利用类型,到2022年以林地、采矿用地、交通运输用地3类为主要土地利用类型,不同景观类型之间发生较大的转化面积,土地利用综合变化率较高。耦合宏观与微观格局生态网络,通过宏观及微观阻力面,分析判断西露天矿宏观生态源地与廊道连接的最小路径,构建研究区的综合生态网络。

Taking west surface mine in Fushun as an example,based on remote sensing,geographic information system and statistics,the evolution law and driving factors of landscape pattern in mining damage area were analyzed,and the evolution speed of landscape pattern was analyzed. Through the method of morphological spatial pattern analysis ( MSPA) and the model of minimum cumulative resistance (MCR),the ecological source area of the west surface mine was identified. The ecological corridor was extracted,and the ecological spatial pattern was built to show the ecological sensitivity and the optimized area in the form of space. The results show that forest land,mining area and mining land are the main land use types in 2014,and forest land,mining land and transportation land are the main land use types in 2022. There is a large conversion area between different landscape types,and the comprehensive change rate of land use is high. Coupling the macro and micro pattern ecological network,through the macro and micro resistance surface,the minimum path of the connection between the macro ecological source and the corridor in the west surface mine is analyzed and judged,and the comprehensive ecological network of the study area is constructed.
