野生动物栖息地变迁与物种多样性的关系探究
摘 要
随着全球气候变化和人类活动的加剧,野生动物栖息地的变迁已成为影响物种多样性的关键因素。本研究旨在探讨栖息地变迁对物种多样性的具体影响机制,并评估其生态后果。通过对中国多个典型生态系统的长期监测数据进行分析,结合遥感技术和地理信息系统(GIS),我们系统性地评估了栖息地破碎化、生境质量下降以及气候变化对物种分布的复合影响。研究发现,栖息地破碎化显著降低了物种的生存概率,尤其是对依赖特定生境的濒危物种影响更为严重。此外,气候变化导致的栖息地范围迁移与物种分布不匹配的现象在北方森林和青藏高原地区尤为突出。本研究的创新之处在于首次将多源数据融合应用于栖息地变迁与物种多样性关系的定量分析,提出了基于生态位理论的适应性模型,为预测未来物种多样性变化提供了新的工具。

THE RELATIONSHIP BETWEEN WILDLIFE HABITAT CHANGE AND SPECIES DIVERSITY
ABSTRACT
With global climate change and human activity, wildlife habitat change has become a key factor affecting species diversity. This study aimed to explore the specific mechanisms of habitat change on species diversity and assess its ecological consequences. By analyzing long-term monitoring data from multiple typical ecosystems in China, combining remote sensing technology and geographic information systems (GIS), we systematically assessed the combined effects of habitat fragmentation, declining habitat quality, and climate change on species distribution. We found that habitat fragmentation significantly reduces the survival probability of species, especially for endangered species that rely on specific habitats. Moreover, the mismatch of habitat range migration and species distribution due to climate change is particularly prominent in the boreal forest and Tibetan Plateau areas. The innovation of this study is the first application of multi-source data fusion to the quantitative analysis of the relationship between habitat change and species diversity, which an adaptive model based on niche theory, and provides new tools for predicting future changes in species diversity.
