With rising global temperatures, global warming has had a profound impact on the genetic diversity of alpine plant species. This paper introduces the context of global warming and the impact on alpine ecosystems, focusing on the challenges of climate change, snowfall and glacier melting to the adaptability of alpine plants. In terms of the concept and importance of genetic diversity, how to measure and protect genetic diversity is crucial. This study explores the mechanisms of global warming on fitness of alpine plant species, including the effects of temperature on gene flow, genetic drift and natural selection, and the relationship between genetic diversity and fitness, emphasizing the importance of protecting and managing genetic diversity in alpine plants. This study aims to provide a comprehensive perspective into the genetic diversity changes in alpine plants in the context of global warming and to provide a scientific basis for future research and conservation. Keywords Global warming; Alpine plants; Genetic diversity; Species adaptability; Conservation and management Global warming is one of the most serious environmental issues today, with widespread and far-reaching impacts on the global ecosystem (Fang et al., 2018). Global warming refers to the phenomenon of the Earth’s surface temperature continuously rising, mainly due to the increasing emissions of greenhouse gases (such as carbon dioxide, methane, and nitrogen oxides) in the atmosphere, leading to the strengthening of the greenhouse effect in the atmosphere. This phenomenon has had a wide and profound impact on the Earth’s ecosystem and biodiversity (Choi et al., 2020). Rising temperatures, increasing extreme weather events, rising sea levels, and changes in ecosystems are all clear signs of global warming. Alpine plants are key members of the ecosystem and are crucial for maintaining ecological balance in alpine areas. They have unique survival strategies and adapt to extreme growth conditions such as low temperatures, strong winds, and high radiation (Cai and Xue, 2018). Alpine plants play a crucial role in hydrological cycling, soil erosion control, and other ecosystem functions. However, due to their unique habitats, alpine plants are often very sensitive to climate change and have relatively poor adaptability. Therefore, global warming poses a threat to the vulnerability of alpine plants, which may lead to species reduction and ecosystem collapse (Inouye, 2020). The main purpose of this study is to deeply explore the impact of global warming on the genetic diversity of alpine plants and provide a comprehensive perspective on this important topic. The article will explore the relationship between the adaptability, genetic diversity, and ecological risks of alpine plants, in order to better understand the impact of global warming on alpine plant populations. In addition, this study aims to emphasize the urgency of protecting and managing the genetic diversity of alpine plants, as well as the key role of interdisciplinary cooperation in this regard. By conducting in-depth research on this topic, this study can provide scientific basis for developing strategies for protecting alpine ecosystems in response to global warming, ensuring the survival of alpine plants and the sustained stability of ecosystems.
