甘肃兴隆山林区马麝(Moschus chrysogaster)隔离种群的生态特征

Some ecological characteristics of the isolated population of alpine musk deer(Moschus chrysogaster) in the Xinglong forest,Gansu Province

兴隆山林区大约在 3 0 0 a前就已完全隔离。现有马麝种群的密度高而相对稳定 ,约为 3 0～ 50头 /km2 ,在目前密度与系统压力下 ,种群数量基本稳定在 50 0 0头左右 ,但却面临着疾病、营养不良与偷猎的威胁。因此应努力建立一个“以开发养保护 ,以保护促发展”的良性循环模式 ,从而为我国自然保护区的建设和发展树立典范。

A completely isolated “green island” has been in Xinglong Mountain for about 300 years.The population densities of alpine musk deer in the forest were high and relatively stable among 30～50 individuals/km\+2 in 1993～1997.Under present conditions,the population size was stabilized basically 5000 individuals or so,and faced with the threats such as diseases,undernutrition and poaching.Therefore,great effort should be made in order to set up an exploitation model through conservation and a conservation model through exploitation so as to a good example for managing Chinese nature reserves effectively.
