摘要
2009年10月对河北塞罕坝地区的黑琴鸡(Lyrurus tetrix)秋季种群密度进行了专项集中调查。结果表明,秋季种群密度为2.20只/km2;与历史资料对比,该地区黑琴鸡种群密度呈明显下降趋势;种群分布发生了变化;繁殖基数、繁殖成功率下降和秋季猎捕是造成黑琴鸡秋季数量下降的主要因素。目前,加强管理、阻止盗猎活动是保护当地黑琴鸡种群的最有效措施。
Population size of the Black Grouse Lyrurus tetrix was surveyed in Saihanba area in October of 2009. The results showed that its population density was 2. 20 ind. /km^2. Compared with the former data,its population density showed a downward trend and its distribution pattern in this area changed. The major threats to this declining population are reduction of breeding individuals,low breeding success rate and hunting pressure in fall. At present,the most effective measure to save this population is to stop the hunting with strict management.
