小城镇规划的创新与设计--以南京市六合区新集镇为例

小城镇规划是两区规划中的重点,但现阶段我国许多地区的小城镇规划存在着重视不够、缺乏特色、资金不足、理念落后、建成规模与预测人口规模矛盾突出等问题,严重影响了小城镇规划的实施效果和可持续发展的实现。文章以南京市六合区新集镇为例,从小城镇规划中存在的问题着眼,提出了小城镇规划中创新的内涵、意义、原则、目标及实施的手段与措施,旨在推进我国的小城镇规划建设,提高城镇的综合竞争力,实现其可持续发展。

On the Evolution and Structure of a Radiation Fog Event in Nanjing

An extremely dense radiation fog event during 10-11 December 2007 was studied to understand its macro-micro-physics in relation to dynamic and thermodynamic structures of the boundary layer, as well as its structural evolution in conjunction with the air-surface exchange of heat and water vapor. The findings are as follows. The extreme radiation fog process was divisible into formation, development, mature, and dissipation phases, depending on microstructure and visibility. This fog event was marked by rapid evolution that occurred after sunrise, when enhanced surface evaporation and cold air intrusion led to a three order of magnitude increase in liquid water content (LWC) in just 20 minutes. The maximum droplet diameter (MDD) increased four-fold during the same period. The fog structure was two-layered, with the top of both the surface-layer and upper-layer components characterized by strong temperature and humidity inversions, and low-level jets existed in the boundary layer above each fog layer. Turbulence intensity, turbulent kinetic energy, and friction velocity differed remarkably from phase to phase: these features increased gradually before the fog formation and decreased during the development phase; during the mature and dissipation phases these characteristics increased and then decreased again. In the development and mature stages, the mean kinetic energy of the lower-level winds decreased pronouncedly, both in the horizontal and vertical directions.
