Abstract: The analysis on microbiological ecology for four types of oil contaminates soils showed that the bacteria utilizing the oil as carbon sources increase,wheras the fugi become less.Zooloea and Bacillu are the dominant bacteria ; Mocor and Cunninghamella,and Fursarium are the dominant fungi streptomyces take the superiority among the actinomyces.The anaiysis on esterase activity showed that the microbes above mentioned have abilies of degrading esters. The biodeg radationrates are 55.45%,56.74%,38.37% and 45.19%respectively,after 53 days,the biodegradation rate can be increased by 12.6% when the dominant microbes are added.

Key words: dew accumulation rate, leaf dew amount, leaf angle, temperature, relative humidity, dew point-leaf temperature depression.
