古田山自然保护区黑麂资源分布与保护现状

The Current Distribution and Conservation Status of Black Muntjac in Gutian Mountain Nature Reserve

2003年3～12月,在古田山自然保护区对黑麂的分布、种群密度和保护现状进行了调查,结果发现,古田山黑麂主要栖息在海拔800～1000m的区域。同时根据样带法估计保护区内黑麂种群密度。结果表明,区内黑麂平均密度为3.30±0.45只/km2,单因素方差分析表明,核心区、缓冲区、实验区黑麂种群密度存在极显著差异(F2,37=19.31,P<0.01)。从整个保护区来看,不同季节黑麂种群密度变化不明显(F3,36=0.36,P>0.05)。食物空间分布的季节性变化可能是黑麂对海拔高度选择变化的重要原因,森林面积的丧失和偷猎是影响黑麂种群在该区稳定生存的主要因素。

From March 2003 to December 2003,the distribution,population density and conser-vation status of black muntjac were surveyed in Gutian Mountain Nature Reserve,Zhejiang Province.The results showed that the optimal habitat elevation of black muntjac was 800～1000m.With dejecta and footmark as indirect indication,the authors used the sampling line method to obtain the field censusing data.The population density was estimated to be 3.30±0.45(ind./km2)in the nature reserve,then in core area,cushion area and experiment area the densities were signifi-cantly different by one way variance analysis(P<0.01).In different seasons,the population densities in nature reserve were insignificantly differencet(P>0.05).The changes of black muntjac in elevations in different seasons were mainly attributed to the seasonal modification of food resource.Losses of forest,hunting and human disturbance were the main threat against black muntjac's survival.According to the result of survey and local conditions,the idea for conservation of black muntjac and suggestion for future management were described in this paper.
