Investigations onMuntiacus crinifrons resources were conducted from October 2012 to May 2013, by stratified sampling method at 15 transects in the core zone, buffer zone, and experimental zone of Jiulongshan National Nature Reserve of Zhejiang, combined with infrared triggered cameras technology(ITCT) and molecular makers. The result showed that the average density ofM. crinifrons was 7.93±0.75/km2 in the Jiulongshan, 10.27±1.17/km2 in core zone, 7.58±0.26/km2 in buffer zone and 4.89±1.28/km2 in experimental zone. Analysis of variance demonstrated that there was significant difference among sample plots(F =1 0.45 > F3,26 = 4.64,P < 0.01). The investigation resulted thatM. crinifrons distributed widely in Jiulongshan National Nature Reserve.%2012年10月和2013年5月，采用分层—样地—样带抽样统计法分别对九龙山自然保护区的核心区、缓冲区和实验区所设置的15条样带进行黑麂（Muntiacus crinifrons）资源调查，结合样带法、红外相机技术法以及分子标记法对九龙山保护区黑麂的种群密度及保护现状进行了调查。结果表明：保护区内的黑麂种群平均密度为7.93±0.75只/km2，其中核心区、缓冲区、实验区黑麂种群密度分别为10.27±1.17、7.58±0.26、4.89±1.28只/km2；通过方差分析，不同样地间黑麂种群密度差异极显著（F =10.45> F3,26=4.64，P <0.01）。这表时，黑麂在九龙山保护区内广泛分布，而主要集中分布在上寮坑、岩坪一带，黄基坪等周边地带为黑麂的次要分布区，其余地区为一般分布区。
