摘  要:
在GIS支持下对贵阳市绿地景观斑块的空间分布、格局特征进行了研究。结果表明,贵阳市绿地景观斑块数量以小型斑块为主。贵阳市绿地景观多样性指数为0.34,均匀度指数为0.21,破碎化指数为0.78,城市绿地景观类型分布不均,各种类型相差较大,破碎度较高,多样性程度低。乌当区和花溪区均以巨大型绿地斑块所占面积最大,白云区和小河区分别以小型和中型绿地斑块所占面积最大,云岩区和南明区以小型绿地斑块为主。花溪区和乌当区景观结构最为合理,小河区次之。贵阳城市绿地总体表现为面积小、以小型和中型绿地景观为主、分布不均匀等特征。

摘  要:
Supported by GIS, space distribution pattern and characteristics of urban vegetation landscape in Guiyang city were studied. Results showed that the number of vegetation landscapes patches in Guiyang was dominated by small ones(30.39%). The diversity index of vegetation landscapes in Guiyang was 0.34, the evenness index was 0.21 and broken degree index was 0.78, Distribution of urban vegetation landscape was uneven. Landscape types was different with higher fragmentation and the low level of diversity. Giant patches area in Wudang and Huaxi district was the biggest, and small patches area in Baiyun district the biggest, medium-sized patches area in Xiaohe district the biggest, and Yunyan and Nanming district were mainly small patches. Landscape structure of Huaxi and Wudang district was the most reasonable, the second was Xiaohe district. Overall, urban vegetation landscape of Guiyang were small area, mainly small and medium-sized patches and uneven distribution.
