<p>This monograph can be divided into three main parts. The first part is a list of endangered species of vertebrates, which systematically includes 87 species of mammals, birds, reptiles and amphibians, and describes in detail the morphological characteristics, distribution range and endangered level of each species, such as Saiga antelope, snow leopard, hunting falcons, etc., focusing on analyzing the threats to habitat destruction, over-hunting and climate change to their survival. The second part is about protection strategies and measures, which put forward suggestions for habitat protection, artificial breeding and legislative protection for different species, such as establishing the Aksu-Zabagrin Nature Reserve to protect rare antelopes, prohibiting hunting of raptors, etc., and emphasizing the importance of international cooperation for cross-border species protection. The third part is ecological monitoring and data support. Through long-term field surveys and specimen analysis, it records dynamic changes in species numbers, such as the impact of fluctuations in the number of grassland rodents on the food chain, and the threat of river pollution to waterbird breeding, providing a basis for protection policy formulation. Provide scientific basis. The full text reflects the combination of biodiversity protection and ecosystem management, and has important reference value for the study of endangered species in Central Asia. </p>
