摘要: 本文对重引入后野放于上海滨江森林公园的獐进行无线电遥测跟踪研究,确定其在公园内286个斑块内的有效活动位点,分析其活动范围,并通过Vanderloeg选择系数和Scavia选择指数分析其栖息地选择。结果显示,以最小凸多边形法得到的重引入獐的活动范围面积从 24.94 hm2 至 83.24 hm2 不等,均值为 58.74 hm2;以固定核空间法得到的面积从 11.23 hm2 至 41.52 hm2 不等,均值为 26.93 hm2。野放后的獐偏好选择面积为 1-2 hm2 的较大斑块和距离水源较远的栖息地。在植被因子的选择上,野放后的獐倾向选择野草地为主、乔木和灌木密度适中、乔木高度10-15m、草本高度 30cm 以上的栖息地,避免选择乔木高度低于 5m、草本高度过低(<5cm)和无草本植物分布的栖息地。建议在今后重引入项目实施中,在郊野公园或者其它城市绿林地内为獐营造植被盖度和密度适中、隐蔽性良好、斑块面积适中的栖息地,并补种高草本,促进物种重引入成功。

Abstract: Chinese water deer were re-introduced to Bingjiang Forest Park, Shanghai. We used radio-telemetry to track the released deer, and obtained valid movement fixes in 286 patches and movement range in the park. Vanderloeg coefficients and Scavia indices were used to evaluate species habitat selection. The results show that by using MCP method, the movement area in the park ranged from 24.94 hm2 to 83.24 hm2, with an average of 58.74 hm2. While using FKE method, it ranged from 11.23 to 41.52 hm2, with an average of 26.93 hm2. We found that the deer showed a strong preference for patches with an area of 1-2 hm2 and a long distance to water. As to vegetation factors, the deer tend to choose areas with more wild herbs, proper density of arbors or shrubs, arbors at the height among 10-15 m and herbs at the height over 30 cm. Meanwhile, they showed negative selection for habitat without vegetation or with lower herb cover (<5cm) or short arbors (<5m). Therefore, we suggest creating habitats with appropriate vegetation cover and density, good hiding property, and moderate patch area, and supplementally plant high herbaceous species for future deer reintroduction in country park and other urban woodland.
