摘要
《秦皇岛市自然生态志》涉及范围在空间上属中尺度,包括不同的自然生态系统,需应用景观生态学研究与分析。秦皇岛市生态多样性非常突出;空间结构呈梯状分布,时间结构上变动较大,生态脆弱度为0.624,属强脆弱带;生态过程特色明显,特别是河流廊道的物质输送作用较强;生态功能多样而重要;生态效益与综合效益都很高。
Qinhuangdao Natural Ecology Annals'research fields are mesoscale in space,including various natural ecosystems,which should be studied and analyzed with landscape ecology principles.Ecological diversity in Qinhuangdao city is obvious,which showed a"cascade"trend in spatial structure,and had great changes in time structure.Ecological vulnerability was0.624,belonging to strong fragile zone.Ecological process had obvious characteristics,especially the strong mass transfer functions of river corridors.Ecological functions were various and important.Its ecological benefits and comprehensive benefits were high.
