摘要: 浑善达克沙地榆树疏林草原作为温带草原的隐域植被,在防风固沙、改善土壤质量和维持生物多样性等方面发挥了重要作用。近年来,气候变化和人类活动的强烈干扰导致沙地榆(Ulmus pumila L. var. sabulosa)种群大幅衰退,这一趋势日益严重。然而,现有研究尚未系统探究沙地榆的生态学特性与保护策略。本文结合沙地榆的现状,探讨其生理生态特征、繁殖策略、共生关系以及对气候和人为干扰的响应,并提出相应的保护措施。研究表明,沙地榆具备多种应对干扰的生态策略,但其未来发展在很大程度上依赖于人类活动的影响。保护措施应结合沙地榆的生态特性,重点通过建立监测样地、增强生物多样性及减少风沙侵蚀来提升生态系统稳定性。未来的研究应深入探讨如何平衡生态保护与区域经济发展,探索生态旅游等新兴产业的融合,以推动沙地榆的恢复与可持续发展。

Abstract: As a cryptic vegetation type in the temperate steppe, the sparse forest grassland of sand elm (Ulmus pumila L. var. sabulosa) in the Otindag Sandy Land have played a crucial role in wind prevention, sand fixation, soil improvement, and biodiversity maintenance. In recent years, climate change and intense human activities have caused a significant decline in the sand elm population, and this trend continues to worsen. However, current research has not systematically investigated the ecological characteristics and conservation strategies of the sand elm population. In this paper, we explored the physiological and ecological characteristics, reproductive strategies, symbiotic relationships, and responses of sand elm to climatic and anthropogenic disturbances, and proposed conservation measures accordingly. The results showed that sand elm employed a variety of ecological strategies to cope with disturbances, but its future development largely depends on the influence of human activities. Conservation measures should consider the ecological characteristics of sand elm, focusing on enhancing ecosystem stability through monitoring plots, increasing biodiversity, and reducing wind and sand erosion. Future research should explore how to balance ecological protection with regional economic development, and investigate the integration of eco-tourism and other emerging industries to promote the restoration and sustainable development of sand elm.
