<p>This monograph can be divided into three parts. The first part is the analysis of the ecological characteristics of plant communities, which systematically describes the types of plant communities in different elevations and ecological areas of Uzbekistan, including desert grasslands, mountainous grasslands, halophytic vegetation, etc., focusing on the analysis of the morphological characteristics, distribution rules and interactions with climate and soil of ephemeral plants, semi-shrub vegetation and xerophytic trees and shrubs. The second part discusses the rational utilization of plant resources. Aiming at forage, medicinal plants and wind-breaking and sand-fixing plant resources, it puts forward the rotational grazing system, artificial grassland construction and endangered species protection strategies, and analyzes the economic value and ecological value of different vegetation types based on specific cases. Function. The third part is regional flora research data, which includes taxonomic information of hundreds of local endemic plants and newly recorded species, including model specimen collection locations, niche characteristics and population dynamics monitoring results, providing a basis for plant diversity in arid regions of Central Asia. Sexual protection provides basic data support. The full text reflects the combination of botany research and sustainable use of resources, and has important ecological and economic value. </p>
