通过对江苏大丰麋鹿保护区Ⅰ、Ⅱ放养区内麋鹿粪堆频率分布的系统抽样调查,发现半野生麋鹿在秋、冬季粪堆呈聚集型分布,分布型服从负二项分布、奈曼A型分布和Thomas分布,其中以负二项分布拟合程度最好。造成粪堆聚集分布的主要原因是环境因素的影响,与麋鹿的习性关系不大。在放养区主要生境类型草地和林地中,粪堆均服从负二项分布。粪堆密度林地大于草地,但粪堆聚集指数草地却高于林地。粪堆的聚集强度与鹿群在该生境中的活动类型有关,当麋鹿粪堆在单一生境内服从负二项分布时,粪堆聚集指数与鹿群对该生境的休息利用率之间存在着明显的相关关系(r=0.988,P<0.05)。粪堆频数调查显示,秋、冬季大丰麋鹿对林地的利用率高于草地。
Based on a systematic sampling survey of the frequency distribution of the elk heap in the Ⅰ and Ⅱ stocking areas of the Dafeng elk protected area in Jiangsu Province, it was found that the semi-wild elk showed an aggregated distribution in the dung and winter dunks. The distribution followed a negative binomial distribution. Type distribution and Thomas distribution, with the negative binomial distribution fitting best. The main reason causing the accumulation of manure stack is the influence of environmental factors, and has little to do with the habit of elk. In the main habitat type grassland and woodland in the stocking area, the dung pile obeys the negative binomial distribution. The density of dung was greater in the woodland than in the grassland, but the dung mass index was higher in the grassland than in the woodland. The accumulation intensity of the dung heap is related to the type of activity of the deer herd in the habitat. When the elk dung heeled in a single habitat follows the negative binomial distribution, there is a relationship between the dung heap mass accumulation index and the resting utilization rate of the herd on the habitat Significant correlation (r = 0.988, P <0.05). Dung heap frequency survey, autumn and winter Dafeng elk utilization of woodland than the grassland.
