环境变化对野生动物种群的影响
摘 要
随着全球环境的不断变化，野生动物种群正面临着前所未有的生存挑战。气候变化导致的全球变暖、极端天气事件频发，以及栖息地破碎化等问题，严重威胁着野生动物的生存环境和种群数量。同时，环境污染，包括化学污染物、微塑料和噪音污染等，也对野生动物种群构成了巨大的威胁。本研究旨在全面探讨环境变化对野生动物种群的影响，并分析野生动物的适应机制。研究内容涵盖气候变化对野生动物栖息地的影响、环境污染对野生动物种群的威胁、人类活动对野生动物种群的干扰，以及环境变化下的野生动物适应机制。通过实地调查、数据分析等方法，本研究揭示了全球变暖、极端天气事件和栖息地破碎化对野生动物栖息地的破坏，以及化学污染物、微塑料和噪音污染对野生动物种群的毒性效应和行为影响。同时，本研究还探讨了城市化、农业扩张和非法捕猎等人类活动对野生动物种群的干扰，以及野生动物在环境变化下的生理适应、行为模式改变和遗传多样性作用。

EFFECT OF ENVIRONMENTAL CHANGES ON WILDLIFE POPULATIONS
ABSTRACT
With the constantly changing global environment, wildlife populations are facing unprecedented survival challenges. Global warming caused by climate change, frequent extreme weather events, and habitat fragmentation pose a serious threat to the living environment and population of wildlife. At the same time, environmental pollution, including chemical pollutants, microplastics and noise pollution, also poses a huge threat to wildlife populations. The purpose of this study is to comprehensively explore the effects of environmental changes on wildlife populations and to analyze the adaptation mechanisms of wildlife. The research covers the impact of climate change on wildlife habitat, the threat of environmental pollution to wildlife population, the interference of human activities to wildlife population, and the mechanism of wildlife adaptation under environmental changes. Through field surveys, data analysis, this study reveals the destruction of wildlife habitat by global warming, extreme weather events and habitat fragmentation, as well as the virulence effects and behavioral effects of chemical pollutants, microplastics and noise pollution on wildlife populations. Meanwhile, this study explores the disturbance of wildlife populations by human activities such as urbanization, agricultural expansion and illegal hunting, as well as the physiological adaptation, behavioral pattern changes and genetic diversity roles of wildlife in response to environmental changes.
