为进一步活跃规划界的学术气氛， 让更多的作者可以通过杂志这一窗口表达自己的学术见解， 本刊从今年开始， 将采取“命题作文”的形式， 点出一些题目， 邀请大家围绕我们给出的命题不定期进行讨论。来稿可长可短， 尤其欢迎千字以内的短文。我们并不认为这种形式能对讨论的话题给出一个圆满的解答， 但起码可以为读者提供深入研究这一问题的不同视角。 In order to further stimulate the academic atmosphere in the planning community and allow more authors to express their own academic opinions through this window of the magazine, this year we will take the form of “proposition essay”, point out some topics and invite everyone around us The given proposition is discussed from time to time. Contributions may be shorter or longer, especially those essays within one thousand words. We do not think this form gives a satisfactory answer to the topic under discussion, but at the very least it offers readers a different perspective on the issue of in-depth study.
