【摘要】 利用层次分析法和非线性拟合法分析了南京市1980-2006年间城市化进程,探讨了城市化与由其造成的城市各项气温(年平均最高、最低气温和年平均气温)增温的影响关系,并结合区域气候变化按时间序列分阶段进一步分析了城市化效应对城市增温的影响程度。结果表明:①1980-2006年间南京市城市化进程对城市化增温影响关系显著,其中对年平均最低气温的影响最为明显,对年平均气温的影响次之,对年平均最高气温的影响最小;②1981-1998年间城市化效应对城市增温的影响远远小于区域气候的影响,但1998-2006年间前者的影响程度大于后者,增温率将近为后者的两倍;③城市化增温趋势呈现出的阶段性特征与南京市城市化进程的特点相吻合。更多还原

【Abstract】 Based on AHP and nonlinear fitting,the urbanization in Nanjing from 1980 to 2006 is analyzed and the relations between the urbanization and temperature increasing from the yearly average maximum、minimum temperature and the yearly average temperature are respectively inquired into. Furthermore,stage Impact of urbanization and regional climate on temperature increase is analyzed according to the time series. The results indicate that:①The urbanization has a great impact on temperature increase by it,and has a greater effect on the yearly average minimum temperature than on the yearly average temperature and has a least effect on the yearly average maximum temperature; ②The impact of urbanization is nearly two times warming rate greater than that of regional climate from 1998 to 2006 while the impact of the former is far less than that of the latter on temperature increase in Nanjing from 1981 to 1998; ③The stage trend of temperature increase by urbanization accords with the characteristics of the process of urbanization in Nanjing.更多还原
