<p>This monograph systematically studies carnation plants in Kyrgyzstan and is divided into four parts. The first part analyzes the shaping of the habitats of Caryophyllaceae plants in the Tianshan Mountains and the arid to alpine climate. The family in the area contains 126 species and 28 genera, with Silene, Tortilla and Stachyflora as the dominant groups. Some species are endemic or rare to the region, highlighting the uniqueness and protection value of the flora. The second part is systematic classification based on morphological characteristics, focusing on describing 31 species of Silene suaveolens (such as drought-tolerant Silene suaveolens), 11 species of Tortillaria (such as Cerastium cerastoides in alpine habitats), and 9 species of Lithothia (such as Gypsophila cepalotes with panicles), revising confusing taxa and providing a species key. The third part divides 18 geographical distribution areas and reveals the influence of altitude gradient: at low altitudes (600- 1,600 meters), the xerophytic species Spergularia media is the dominant species, and at middle and high altitudes (2,500 - 3,500 meters), the cold-resistant species Stellaria irrigua, etc. Most species adapt to gravel slopes and meadow habitats, and some species show soil preference. The fourth part discusses reproductive strategies and stress resistance mechanisms. Some species have medicinal or ecological functions. In response to the problem of habitat fragmentation of endemic species such as Silene korshinskyi, a priority protection list and recommendations for habitat connectivity restoration were proposed, emphasizing the dynamic monitoring of alpine species. </p>
