摘　　要：2004—2006年每年的4—7月,在内蒙古图牧吉地区对大鸨种群数量及繁殖情况进行了调查,并分析了气温、降雨量、湿度、蒸发量及风速对大鸨种群数量的影响。结果表明:3年间大鸨种群数量持续下降。研究区内连续几年高温干旱,气温逐年升高、降雨量逐年减少,这是影响大鸨种群数量逐年下降的主要原因。A survey was conducted to study the population size and reproduction situation of Great Bustard in Tumuji area of In-ner Mongolia in April-July during 2004 and 2006. The effects of air temperature, precipitation, humidity, evaporation and wind speed on the population size of Great Bustard were analyzed. Results showed that the population size of Great Bustard decreased continuously over the total observation period due to high air temperature and drought continuously occurred in Tumuji during 2004 and 2006. Temperature rise and precipitation decrease are the main reasons which cause the population decline of Great Bustard.
