But the massive project practice proved these technical measure the application fundamentally has not solved the rut problem; Regarding the city"urban heat island effect"the question, the measure which uses generally is enhances the city round-off work and the expanded lawn, the water place area, but the city major part area is constructed and the path is covering, the ultra big city its round-off work extremely is in particular difficult to enhance, simultaneously the spatial distribution very is possibly imbalanced.

但是大量的工程实践证明这些技术措施的应用也未从根本上解决车辙问题；对于城市"热岛效应"问题，普遍采用的措施是提高城市森林覆盖率及扩大草地、水地的面积，但城市的绝大部分面积被建筑和道路覆盖着，尤其是超大城市其森林覆盖率极难提高，同时空间分布可能又很不均衡。

Research about China must study her control approach, because in human history, you cannot find another one like Chinese culture, which has been entirely controlling the citizen抯 life not only in political and conscious level, but also the substantial and spatial realm coving from macro-scale urban planning, through the traditional architectural construction regulation, to every sophisticated detail of daily life since thousands of years ago.

研究中国必须要研究其控制方式。因为历史上恐怕再难找到像中国文化这样，在几千年中如此事无巨细地讲究控制，不仅是在政策和意识形态上，并且也是物质化和空间化的：从城市规划的宏观规则，建造营造的中观法式，到生活用品的每一个微观细节。

The exuberant spatial effect of this small-scale Baroque circulation device is mesmerizing You half expect Georges Guetary to pop out and croon "I'll build a Stairway to Paradise," as he did so memorably in the 1951 film An American to Paris.
