The windbreak and sand fixation rate of Tamarix chinensis is between 40% and 60%. The windbreak and sand fixation rate of Tamarix chinensis is between 40% and 60%, and the specific value may vary with different regions, different species of Tamarix chinensis and different soil types. Tamarix chinensis is a common windbreak and sand-fixing plant with strong adaptability and vitality. In desert areas, Tamarix can grow into tall shrubs, forming dense vegetation, effectively blocking the erosion of wind and sand and fixing the soil. At the same time, Tamarix chinensis can absorb a lot of carbon dioxide, release oxygen and improve air quality. The windbreak and sand fixation rate of Tamarix chinensis is affected by many factors, such as planting density, growing environment, soil type and so on. In order to improve the windbreak and sand fixation effect of Tamarix chinensis, it is necessary to rationally plan the planting density, select suitable varieties, and strengthen management and maintenance to ensure the healthy growth and sustainable reproduction of Tamarix chinensis. The windbreak and sand fixation rate of Tamarix chinensis is generally between 40% and 60%.
