摘　　要：研究以攀枝花市盐边县红格镇为例,应用Fragstats软件对景观格局指数进行计算,对不同土地利用类型的景观特征进行度量和分析,利用景观破碎度和景观多样性指数的空间分布值提取城市绿心。结果表明,红格镇不同的用地类型其景观指数特征具有较大差异,而土地利用开发多元化活动逐渐改变和影响当地的景观格局特征。当地绿色带状廊道主要由绿色河流廊道构成,绿带具有长度短,间断多,连接度低等特点。采用城市生态建设的微循环理论中的微绿地措施,提出了社区住宅立体绿化;调整乔灌木的配比,提升林木郁闭度;建立街区公园,公共开放空间遮荫;道路低冲击设计措施;斑块之间的廊道连接与网络化等具体建议,为城市绿色廊道的规划建设提供更好的参考依据。This paper takes Hongge county in Panzhihua as case-study,calculates its landscape pattern index with Fragstats software,and finally selects the city green core by evaluating the spatial distribution of landscape fragmentation index and diversity index.The results indicate that landscape index characteristics vary with differentiating land use patterns in Hongge town;and the diverse land use developments gradually influence the local landscape pattern.The local green corridor mainly consists of river corridor,which is of short length,multi intervals and low connectivity.Therefore,drawing from the micro-green-land approach,the following strategies are recommended： vertical greenery in residential communities,adjusting the trees-shrub-ratio,building street parks and public open space shading,and adopting low impact road design strategy etc.The conclusions of this research aim at providing a better reference to the upgrade benign cycle in regional ecosystem and the planning of green corridor in cities.
