老外如是说法:
This article has been retracted.
Reason: This article substantially copies an article by Matthew Luck and Jianguo Wu, “A gradient analysis of urban landscape pattern: a case study from the Phoenix metropolitan region, Arizona, USA” published in Landscape Ecology 17 (4), pp. 327–339,2002. The authors Zhang et al. have indicated in response that this does not amount to plagiarism because the article by Matthew Luck and JianguoWu was cited in their paper. In my view, the amount copied exceeds the usual purpose of citation (to refer to prior relevant work) and amounts to plagiarism.
