摘要
:利用 1999年 12月云南严重寒害期间的气象资料和热区主要经济作物 (橡胶和咖啡 )的受害资料 ,从气象状况方面分析了受害的原因。认为 ,本次寒害持续日期长、低温时间多、影响深度深是造成灌木类经济作物 (如咖啡等 )受害严重的原因 ;而寒害期间 ,晴天多 ,日照强 ,昼间气温高 。
It was discussed the meterorological cause of cold damag ing to tropica l crops in 1999 by analyzing the data of meteorological information and cold dam aging to dominating economic crop in tropical zone in Xisuangbanna in Dec 1999. On the basis of these data, meteorological cause of cold damaging to tropical cr ops were discussed. The results indicated that: duration of this cold-snap is a good wile, duration of low temperature, intension is severity, all these charact er is the cause of cold damaging to dominating economic crop; Because of more cl ear-day 、intensive sunshine and higher temperature on day-time, cold damaging to dominating economic arboreal crop is light.
