| 摘 要： | 利用1964—2011年廊坊9个气象观测站的日平均气温数据,分别利用可行性倾向估计、累计距平、M-K检验三种分析方法,分析了廊坊地区近50 a气温的气候变化特征;并通过统计分析,研究了廊坊地区年平均气温与全社会固定资产投资总额、城市总人口数、国内生产总值三项城市发展指标的关系。结果表明:廊坊市人口、GDP、全社会固定资产投资总额均与年平均气温显著相关。近48 a来,廊坊城区站与郊区站的温度差成逐步减小趋势,受城市化影响,廊坊地区年平均温度呈缓慢上升趋势,空间分布特征郊区站低于城区站,城区站每10 a增温0.5℃,郊区站每10 a增温0.41℃,10 a总增温0.42℃。

| Abstract: | Based on the daily average temperature data from 9 meteorological observation stations during 1964 to 20i 1 in Langfang, analyze the climate characteristics of temperature in the recent 50 years with linear trend, ac- cumulated variance and Mann-Kendall methods. The relations between annual mean air temperature and 3 urban development indicators, including urban population, GDP, total social fixed assets investment was studied. The results show that, the population, GDP ,total social fixed asset investment and the annual mean temperature in Langfang have significant correlations. In recent 48 years, the temperature difference of Langfan suburban station decrease gradually. Because of urbanization, the annual mean air temperature g city and the have been as- cending slowly, the temperature of urban is higher than the suburban, the increasing rate of urban station tem-perature is 0.5 ℃/10a, and suburban station is 0.41 ℃/10a,the total rate of warming 0. 42 ℃/10a; |
