Microclimate Effect Of The Afforested Area In The Middle Taklimakan Desert Oil Field

In this paper, it was analyzed to climatic characterizations in the protective forest belt,the afforested area(standard section)and the desert area according to the data of the automatic meteorology observation station located in the protective forest belt, Tazhong meteorology observation station located in the afforested area and the automatic meteorology observation station located in the desert area in July, October and January from 2006 to 2007. The results showed:1. In July the mean air temperature of the afforested area(standard section)is 0.4℃lower than the desert area. Contrast to the desert area, daily range of air temperature of the afforested area(standard section)is bigger. The mean air humidity of the afforested area(standard section)is 0.8% higher than the desert area. the mean wind speed of the afforested area(standard section)is 1.1m/s lower than the desert area.2. In October the mean air temperature of the protective forest belt is 2.6℃lower than the desert area, which of the afforested area(standard section)is 3.3℃lower than the desert area. The daily range of air temperature: the afforested area(standard section)> the protective forest belt > the desert area. The mean air humidity of the protective forest belt is 10.5% higher and that of the afforested area(standard section)is 12% higher than the desert area. The mean wind speed of the protective forest belt is 1.8m/s lower than the desert area. The mean wind speed of the afforested area(standard section)is 0.7m/s lower than the desert.3. From January 25 to January 30 the mean air temperature of the protective forest belt is 4.0℃lower than the desert area. The mean air temperature of the afforested area(standard section)is 4.8℃lower than the desert area. Daily range of air temperature: the afforested area(standard section)> the protective forest belt > the desert area. The mean air humidity of the protective forest belt is 3.3% higher than the desert area. The mean air humidity of the afforested area(standard section)is the same to that of the desert area. The mean wind speed of the protective forest belt is 0.7m/s lower than the desert area. The mean wind speed of the afforested area(standard section)is 0.5m/s lower than the desert area.4. In the middle Taklimakan desert oil field the days of dust-storm were less than before, but the days of the floating-dust and blowing-sand were more than before from 1997 to 2006. Human being built variety of buildings, planted variety of trees and grass and strengthen the sand, which affected variation of the floating-dust, blowing-sand and dust-storm.The microclimate effect of the Middle Taklimakan Desert Oil Field was very prominent.
