The only way is to read the text of the city, and observe and experience the city space in order to understand the incidents in the city space and the utilization of the space. This causes human to re-recognize the residential city again and remind the collective memory of people to the city. People will further think about the relationship between human and city and reposition the own role in the city.

而唯有透过城市文本的阅读与城市空间的观察、体验，暸解城市空间里发生的活动事件与空间的使用情形，使人重新去认识自己居住的城市，以唤醒人对城市过往的集体记忆，进而思考人与城市之间的关系，并重新定位自己在城市中扮演的脚色。

To investigate the spatial-dependence of heterogeneity at multiple scales for a community, we selected a representative plot of 100 m×100 m in the mountainous evergreen and deciduous mixed broad-leaved forest in Sichuan, southwest China (102°50'E, 30°02'N).The location of every tree was mapped by compass, and all-scale analysis of spatial structure of forest community was conducted by the method of PCNM (principal coordinates of neighbor matrices).
