摘要
[目的]研究松鼠种群动态特征及其对食物因素的响应机制。[方法]2007～2012春、秋季分别在红花尔基樟子松林国家级自然保护区用样线法开展松鼠种群调查,同时收集樟子松结实量数据。[结果]樟子松结实量对松鼠春季种群密度有显著影响。红花尔基保护区松鼠的种群密度处于持续下降中。[结论]食物资源变化对松鼠的种群密度有显著影响,需要对松鼠种群密度动态开展持续的监测和研究。
[Objective] The aim was to study the population dynamics characteristics of Sciurus vulgaris and response mechanism to food factors.[Method] Every spring and autumn during 2007-2012,we adopted line-intercept method to investigate the population dynamics of Sciurus vulgaris and meanwhile collected the data of cone production of Pinus sylvestris in Honghuaerji Nature Reserve.[Result] The cone production of Pinus sylvestris significantly affected the population density of Sciurus vulgaris in spring.The population density of Sciurus vulgaris in Honghuaerji Nature Reserve continually decreased.[Conclusion] The variation of food resource showed significant effects on population density of Sciurus vulgaris.It was necessary to constantly detect and research on the density dynamics of Sciurus vulgaris population.
