| 摘 要： | 利用德州11县市1951～2005年温度、降水资料,计算气候干燥度,1981～2005年与1951～1980年相比全市干燥度由1.45增大到1.64,已由原来的半湿润气候变化为半干旱气候。各县市降水量呈减少趋势,平均每10年减少19.64mm;气温呈上升趋势,平均每10年升高0.11℃,冬季升高0.30℃,冬季增温显著,北部县市已由原来的冰冻区变化为微冻区,全市均为微冻区。由于气候条件变化,相应场地环境类别与腐蚀介质指标的调整系数标准应作调整改变,场地环境类别由Ⅱ类转变为Ⅰ类,腐蚀介质指标的调整系数均取0.9。 |

| Abstract: | By using the temperature and precipitation data from 11 counties in Dezhou,the aridityies of climate from 1981 to 2005 are calculated and compared with those from 1951 to 1980.The aridity increased from 1.45 to 1.64,and the city has become semi-arid from semi-humid climate.Meanwhile,the precipitation reduced by 19.64 mm per 10 years averagely in all counties.But the temperature is rising with an increase rate of 0.11 per 10 years averagely,and 0.3 degree per 10 years in winter.Significant warming is found in winter.The northern part has become frozen zone from sub-frozen zone.Because of the climatic condition change,the local environment and the corresponding types of the adjustment of local corrosive media standards are changed from Category 2 to Category 1,with corrosive media index adjustment coefficients being 0.9. |
| Keywords: | climatic change aridity local environment corrosive medium anticorrosion design |
