摘　　要：通过FRAGSTATS 3.3软件获取了荆各庄矿区不同时期的景观指数.景观格局信息表明矿区景观优势度已经发生了较大变化,原优势景观耕地规模下降,新增采矿积水、矿业建设用地、矸石山用地;村落是各景观类型中变化最剧烈的;景观格局信息熵处于上升趋势;各类景观类型变化规律不同,其中,农田被其它景观分割、蚕食,菜地零星分布,林地是生态重建的主要景观,冲沟减少且自然边界人工化,采矿积水区面积增加、数量下降、形状趋于规则,鱼塘数量增加,村落不断迁移,均匀度下降,道路廊道连通性增强.充分说明采矿与城市化对城乡结合部矿区景观格局影响显著,土地复垦与生态重建使景观格局趋于安全.Calculated the indexes of all types of landscape in Jinggezhuang mining area in different periods by the soft FRAGSTATS 3.3. The landscape pattern information indicates that the landscape dominance degree in mining area has changed greatly, and the scale of the former dominant landscape the cultivated land declines, and the min- ing seeper, mining built-up land and waste pile land become new kinds of landscape; the rural settlement land changes most in all of landscape types ; the information entropy of landscape pattern is in a rising trend ; each type of landscape shows its own change regularity ： ① the farmland is divided and integrated by other types of landscape ; ② the vegetable plots distribute dispersedly; ③ the forest land is the main landscape for the ecological reconstruction; ④ the gulch declines, and its natural boundary becomes artificial; ⑤ the area of mining seeper increases, and its quantity declines, and the shape tends to be regular ; ⑥ the quantity of fish ponds increases ; ⑦ the villages move continuously and the uniformity of rural settlement land declines; ⑧ the connectivity of road corridor enhances. The analyses indicate adequately that mining and urbanization have great influences on the landscape pattern in mining area in urban-rural fringe. And the land reclamation and ecological reconstruction make the landscape pattern to security.
