【摘要】 以1994年和2002年徐州市的土地利用图为数据源,选取景观丰度、多样性指数、斑块密度和平均斑块分维数等景观指标,利用相关分析的方法对景观空间格局与城市生态效应之间的关系进行了初步探讨。结果显示:在所选择的景观格局指标中,景观丰度、景观类型多样性与生态效应呈显著正相关,斑块密度、分维数与生态效应呈显著负相关,表明景观空间格局对生态效应有较大影响。更多还原

【Abstract】 Based on the land use map 1994 and 2002 of Xuzhou City,some landscape indexes,such as landscape richness,diversity,patch density and fractal dimension,are applied to analyzing the landscape pattern and ecological effect and the relationship.The relationship between the indexes of landscape pattern and the urban ecological effect showed that the urban ecological effect had significantly positive correlation with the indexes of the richness and the diversity,and significantly negative correlation with the indexes of the patch density and fractal dimension.And this shows landscape spatial pattern has a larger impact on ecological effect.更多还原
