Paper Abstract

Microclimate observation at 2 heights (10 and 50 centimeters) in young cotton plants fields with both normal windbreak and non-normal windbreak were carried out when a dust storm took place in May 1998. Meteorological indices on the intensity of damage to the young cotton plants were obtained. These results were shown that 5% young cotton plants were damaged slightly when average velocities at the 2 heights were 1.5m/s, 2.6m/s respectively; 10% young cotton plants were damaged when these velocities were 1.6m/s, 2.9m/s respectively; 20% young cotton plants were damaged when these velocities were 1.8m/s, 2.9m/s respectively; 35% young cotton plants were damaged seriously when these velocities were 2.3m/s, 3.4m/s respectively. Economical evaluation on these plants’ damages caused by the dust storm was also conducted. The above indices were tested to be suitable in Hetian region. It is suggested that normal windbreak should be built in Hetian region in future.
