中文摘要：

根据珠江三角洲珠海、中山、东莞、广州、深圳5个城市气象站1973~2008年常规气象资料,利用滑动平均和Mann-Kendall非参数统计检验法研究了珠江三角洲快速城市化不同经济发展时期（经济发展初期、经济快速发展期、经济发展稳定期）对城市温度、风速、风向的影响.结果表明,不同城市环境气象要素变化的差异与城市发展程度相关.城市平均温度变化率与城市化推进速度成正比,风速变化率与城市化进程成反比,主导风向出现频率随城市化下降.这些结果可归纳总结为定性的概念曲线.

英文摘要：

Impact of different urbanization stages（primitive,rapid and stable） on the temperature,wind speed and wind direction in the five rapid urbanization cities（Zhuhai,Zhongshan,Dongguan,Guangzhou,Shenzhen） of Pearl River Delta（PRD） was studied with the running mean and Mann-Kendall statistical significance test of 1973~2008 observations at five weather stations.It was found that the temperature changing rates were positively proportional to the urbanization increasing rates while both the changing rates of wind speed and the frequency of dominant wind direction were negatively proportional to the urbanization increasing rates.These results had been visualized as conceptual curves in the present paper.
