摘　　要：以哈尔滨市群力新区绿地系统为研究对象,在遥感和GIS技术支持下,从绿地类型的基本斑块特征、斑块类型等级、景观异质性及景观破碎化4个层面上选取14个指数,对群力新区绿地景观格局进行分析。结果表明:研究区绿地率低,各类型绿地斑块数分布失衡,面积差异较大,形状复杂程度各异。景观多样性较好,优势度明显,但缺失绿地类型,且分布不均匀,破碎化水平较高。针对研究区绿地景观格局中存在的问题,提出群力新区绿地生态规划建议,使研究区绿地系统具有良好的景观格局,更有效的发挥城市绿地的生态功能。Qunli district green system of Harbin City was selected as research subjects in this study, under the support oI remote sensing and G1S, the 14 indexes were selected from the basic patch features of green types, the ranks of patch types, the landscape fragmentation and the landscape heterogeneity to describe the landscape pattern characteristic quantitatively of Qunli district green space system. The results showed that the green rate was low,the patch number was imbalance, patch area was significant different,and the complexity of plaque shape was various among different types of green space. Landscape was in large diversity and the dominant landscape was obvious, but it was lack of other types of green space and in uneven distribution, furthermore, fragmentation was serious in this district. Aimed at the problems existing in the green space landscape pattern in this study area, Qunli district green space ecological planning proposals was put forward to make the landscape pattern of the green space system better in this study area and the ecological function of urban green space more effectivily.
