摘要: 为研究义乌小鲵生境特征及选择偏好,本研究于2023年12月在浙江省金华市对其栖息地开展系统性调查,通过设置38个研究样方与57个对照样方,结合主成分分析(PCA)与资源选择函数(RSF)模型,量化分析其生境偏好及生态适应特征。结果表明: 义乌小鲵繁殖期偏好较低水温[(10.20±0.51) ℃]、弱碱性[pH (7.14±0.04)]、水体透明度约0.2~0.4 m的小面积[(85.97±40.79) m2]临时静水塘。岸边植被以竹林(42.1%)和草丛(28.9%)为主,繁殖坑沉水植被覆盖率较高(65.8%)。水体物理特征(面积、温度)、水质指标(pH、透明度)、植被类型(岸边竹林、沉水植物)及卵袋附着物为关键影响因子,其生境选择受水体-植被-地形多因素协同调控。研究结果揭示了义乌小鲵繁殖期生境选择偏好,为这一濒危物种的栖息地保护与管理提供了科学依据。

Abstract: To investigate the habitat characteristics and habitat preferences of Hynobius yiwuensis during the breeding season, we conducted a systematic survey in Jinhua City, Zhejiang Province, in December 2023. Based on data from 38 study plots and 57 control plots, we quantitatively analyzed its habitat preferences and ecological adaptation mechanisms by using principal component analysis (PCA) and resource selection function (RSF) models. The results showed that H. yiwuensis preferred small temporary and still water ponds with lower water temperature [(10.20±0.51) ℃], slightly alkaline pH (7.14±0.04), and water transparency of 0.2-0.4 m, with an average area of (85.97±40.79) m2. The riparian vegetation was dominated by bamboo forests (42.1%) and grasslands (28.9%). The coverage of submerged vegetation in breeding pits reached 65.8%. Key influencing factors included physical water characteristics (area, temperature), water quality indicators (pH, transparency), vegetation types (riparian bamboo forests, submerged plants), and egg mass substrates, with habitat selection synergistically regulated by factors of water-vegetation-terrain. Our results revealed the quantitative characteristics of breeding habitat in H. yiwuensis, which would provide a scientific basis for targeted conservation and management of this endangered species and its habitat.
