Abstract: The exponential growth of the economy and society has resulted in a substantial need for superior urban green spaces, consequently fostering a significant surge in urban landscape construction. The integration of plant landscapes in urban landscape construction is crucial. The rational use of plant landscape resources to create high-quality urban green spaces is of great significance for promoting urban sustainable development. Hence, the primary aim of this study was to investigate the landscape and ecological functions of indigenous plants in the context of urban landscape implementation and then provide utilization strategies of indigenous plants for urban landscape construction. This research focuses on the utilization of native plants in Aksu’s urban green spaces (a city in northwest China). Through a contrastive analysis of the dust retention, windbreak and sand fixation, and landscaping capabilities of these native plants, certain indigenous species are identified as suitable candidates. Specifically, Styphnolobium japonicum and Ulmus densa exhibit a dust adhering per plant of 656.50 and 388.46 g·m −2 , respectively. Consequently, augmenting their planting proportion can effectively augment the overall dust adhering within the garden. The windbreak distances of Populus bolleana , Populus euphratica , and Styphnolobium japonicum were found to exceed 60 m, indicating their effectiveness in mitigating wind and sand erosion. Therefore, strategically planting these species can contribute to the establishment of a robust urban windbreak forest. Additionally, optimizing the arrangement of Rosa multiflora , Hippophae rhamnoides , Berberis thunbergii , and Salix matsudana can enhance the aesthetic appeal of urban gardens. The utilization of native plants holds promise in enhancing the ecological and landscape functions of urban gardens in Aksu. The effective enhancement of the ecological function and the landscape effect of urban gardens can be achieved through the appropriate reconstruction with native plants. The findings of this study hold significant reference value for the urban landscape architecture in arid urban areas.
