Abstract: The investigation of low air temperature in two farms in Lianjian County was made.The results showed that the biggest temperature inversion occurred in the top of the hill,when the relative height of hill is below 50m.The biggest temperature inversion occurred in about 70m,while the relative height of hill is 80m,In the course of low air temperature in the winter of 2004/2005 in Pudong farm of Lianjian County,olives which planted below 44m above sea level suffered freeze harm,while olives which planted between 68m to 85m above sea level did not suffer freeze harm.When the minimum air temperature is below-2.0 ℃,olive leaves would be frozen.When the minimum air temperature is below-2.7 ℃,the first top sticks of olive would suffer freeze.When the minimum air temperature is below-3.0℃,the second top sticks of olive would be frozen.
