【摘要】：矿产资源的开采虽然使资源型城市的社会经济迅猛发展,但也造成了环境污染和景观安全格局破坏。以资源型城市武安市为研究区,基于"源—汇"理论和最小阻力模型,确定武安市的"生态源"和"干扰源",构建综合阻力面,提取重要生态廊道,分析其景观安全格局状况。研究结果表明:(1)"生态源"集中分布在武安市西部自然保护区,中东部分布较少且连通性差;(2)矿产资源开采区的生态阻力值较大,交通建设对生态过程扩展起阻碍作用;(3)生态廊道网络布局特征明显,南、北氵名河连贯东西,南北方向因生产建设干扰强烈出现断层;(4)矿区周围生态用地破碎严重,应将生态规划与城市规划、矿区规划相结合,整体上保护资源型城市的景观生态安全格局。
[Abstract]:The exploitation of mineral resources makes the rapid development of social economy in resource-based cities, but it also causes environmental pollution and destruction of landscape security pattern. Based on the theory of "source-sink" and the minimum resistance model, the "ecological source" and "interference source" of Wuan city were determined, the comprehensive resistance surface was constructed, the important ecological corridor was extracted, and the landscape security pattern was analyzed. The results show that the "ecological source" is concentrated in the west nature reserve of Wuan city, and the ecological resistance value of the mining area of mineral resources is higher in the middle and eastern regions with less distribution and poor connectivity. Traffic construction hinders the expansion of ecological process. (3) the distribution of ecological corridor network is obvious, and the ecological land around the mining area is broken seriously, with a link between east and west of the south and north rivers, and a fault in the north and south direction because of the strong interference of production and construction. Ecological planning, urban planning and mining area planning should be combined to protect the landscape ecological security pattern of resource-based cities as a whole.
