It is of theoretical significance to study the plasticity and biomass allocation characteristics of cloned plants in different degradation stages of clonal plants, and to explore the use of heterogeneity resources and adaptive strategies. The alpine meadows in the source regions of the Qinghai-Tibet Plateau are degraded by human and natural factors such as grazing, rodent activity, and climate warming, resulting in a large number of patched habitats and large areas of secondary bare land/black soil. There is plenty of room for the phenotypic plasticity of cloned plants. The bulk density of the soil is also an influencing factor for the growth of related plants. The soil bulk density meter can effectively measure the soil bulk density. However, due to the variation in soil nutrients and physical characteristics of degraded grassland, which may affect the expression of certain characteristics of clonal plants, a comparative study of clonal growth characteristics of clonal plants in degraded meadow habitats and non-degraded meadow habitats can reveal The ecological adaptation strategies and adaptive mechanisms of clonal plants to different habitats, and the verification of habitat adaptation hypotheses, provide a theoretical basis for studies on the grazing management and degradation succession mechanisms of alpine meadows, and provide a basis for the restoration and reconstruction of degraded meadows in alpine meadows.

Take mixed samples, and after pretreatment, determine the available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium, organic matter, and total salt. In addition, the soil bulk density is measured by the soil bulk density meter, and the soil moisture content The soil moisture detector used for measurement was repeated 15 times in each plot.
Through the measurement of soil bulk density instrument, it was found that the change of plant distribution abundance determines the individual's fitness change, that is, the local living environment has a direct impact on the life history of plants. Community factors, interspecific competition, soil characteristics, and microclimatic factors, and other habitat factors affect the growth, survival, and reproduction of plants. Degradation of alpine meadows changed the structure, function, and soil properties of the plant community, and the underlying surface changed significantly. The present study shows that degraded meadows have significant variations in species composition, number, coverage, and habitat characteristics of plant communities, and influence the clone growth behavior and morphological characteristics of the clones of the typical stolon plant P.
