本研究探讨了人为干扰（农业、林业、狩猎和野生家犬）对鹿的种群密度和日常活动模式的影响。我们量化了土地利用（阔叶林，针阔混交林，天然草地，亚高山植被，林业面积和农业用地）的影响，沿着狩猎压力，以及野生家犬和野生猕猴对鹿的密度。土地利用的影响进行了分析，在不同的空间尺度和模型选择程序（广义混合模型）被用来检查在每个空间尺度上的鹿的密度和日常活动模式的影响因素。影响因素的组合因密度和日常活动模式而异，并随空间尺度而变化。将具有最小赤池信息准则值的空间尺度定义为密度和日常活动模式中的每一个的有效空间尺度。在有效空间尺度上，阔叶林覆盖率、天然草地覆盖率和猕猴密度对鹿群密度有正影响，农地覆盖率和混交林覆盖率对鹿群密度有负影响。在鹿的日活动模式中，农业用地、林区、天然草地、亚高山植被和犬密度的日活动减少，夜间活动增加。曙暮光活动增加狩猎压力和亚高山植被，减少与农业用地。因此，每日活动模式是敏感的人为干扰比密度的类型。检测适当的空间尺度，应管理显着的人为干扰是有效的野生动物保护至关重要的。
This study examined the influence of anthropogenic disturbance (agriculture, forestry, hunting and feral domestic dogs) on the population density and daily activity pattern of deer. We quantified the effects of land use (broad-leaved forest, mixed coniferous/broad-leaved forest, natural grassland, subalpine vegetation, forestry area, and agricultural land), along with hunting pressure, and densities of feral domestic dogs and wild macaques on deer. The effects of land use were analyzed at various spatial scales and a model selection procedure (generalized mixed model) was used to examine the effects of factors on density and daily activity pattern of deer at each spatial scale. The combinations of influential factors differed between density and daily activity pattern and changed with spatial scale. The spatial scale with the smallest Akaike’s Information Criterion value was defined as the effective spatial scale for each of density and daily activity pattern. Deer density was affected positively by the percentage of area covered by broad-leaved forest, natural grassland and macaque density, and negatively by percentage of area covered by agricultural land and mixed forest at the effective spatial scales. For the daily activity pattern of deer, agricultural land, forestry area, natural grassland, subalpine vegetation and dog density reduced diurnal and increased nocturnal activity. Crepuscular activity increased with hunting pressure and subalpine vegetation, and decreased with agricultural land. Thus, daily activity pattern was sensitive to more types of anthropogenic disturbance than density. Detecting the appropriate spatial scales at which significant anthropogenic disturbance should be managed is essential for effective wildlife conservation.
