摘 要:对兴隆山马麝资源的种群密度、种群数量和种群结构以及负增长原因进行了研究分析。结果表明,兴隆山林区的马麝主要生活在食物丰富、人为干扰少、避敌条件好的生境中,此种生境种群密度最高,可达42 88头/km2,平均种群密度为23 40头/km2;种群数量呈下降趋势,平均下降率为24 33%;种群结构中,雌雄性比约为3∶2,年龄在2~5龄间居多,仔麝平均每胎产仔数为1 14头;马麝种群呈负增长的主要原因是偷捕盗猎违法行为所致。同时,提出了几点兴隆山马麝资源保护措施。The population numbers, densities, structure and reasons of negative increasing of Moschus chrysogaster in Xinglong Mountain were studied in the paper. The results showed: the Moschus chrysogaster mainly distribute in habitat with rich food, less human disturb and easy escape from enemies and its average population density is 42.88 individuals per square kilometer; population number is decreasing and the average decreasing rate is 24.33 percent; the female and male Moschus chrysogaster ratio is 3∶2, among them with 2~5 year-old is dominant and the birth rate of each embryo is 1.14; the main reason of decreasing of Moschus chrysogaster population number is illegal hunt activities. Meanwhile, the simple protection countermeasures were put forward as well.
