野生动物学报, 2011 2009年7月、8月,2010年3月中旬、5月下旬,对内蒙古达赉湖地区蒙原羚进行野外考察并在生境适宜度分析的基础上,利用FRAGSTATS 3.3软件对达赉湖地区蒙原羚生境进行景观格局分析。通过比较1998年和2010年达赉湖地区蒙原羚生境适宜度评价结果,表明内蒙古达赉湖地区蒙原羚一般适宜生境、中度适宜生境和适宜生境的斑块不断被分割成更小的斑块,破碎化程度加大。蒙原羚不适宜生境斑块面积在增加,而一般适宜斑块、中度适宜生境和适宜斑块面积在减小,并且适宜生境面积变化程度最大 ...

, 2004 利用1970年与2000年的土地利用现状资料,采用地理信息系统软件Mapinfo7.0和景观指数计算软件Apack2.22对福建省建宁县农业发展转型期前后的景观格局变化进行了定量分析.研究结果表明,①30年来,景观的基质正在发生转换,1970年样区内以林地为基质;到2000年人工景观斑块类型在明显增加,果园有成为景观基质的趋势,景观多样性从0.873上升到1.462,景观优势度从0.840下降为0.549,聚集度由0.835下降为0.732,景观破碎化程度加剧;②转型期前后林地、水田和水域的连接度由9 ...
