中文摘要:

    东洞庭湖观鸟时段为深秋至冬季。影响观鸟的气象要素包括降雨、风速、能见度,以及雾、降雪、积雪、雨凇、大风等天气现象。通过历史资料的对比分析,制定观鸟气象指数影响因子取值规则,采用因子加权法,将逐日观鸟气象影响因子判别指标序列划分为5个取值区间,设计了观鸟气象判别指标和观鸟气象指数,并定义观鸟气象指数含义。

Abstract:

Bird-watching time is from late autumn to winter in East Dongting Lake. Meteorological factors affecting bird-watching include precipitation, wind speed, visibility, fog, snow cover, rime, wind and other weather phenomena. Based on the comparative nalysis of historical data, this paper formulates the rules for determining the weather factors of bird-watching by using the factor weighting method, divides the index series of identifying factors of bird-watching weather into five value ranges, designs the weather indicators of bird-watching and the weather index of bird-watching, and defines the meaning of the weather index of birdwatching.
