草原和荒漠植物多样性监测网规划与建设进展

Plan and construction progress of the Steppe and Desert Plants Diversity Observation Network

草原和荒漠是我国北方和青藏高原地区最主要的植被类型,生物多样性资源独特、丰富。草原和荒漠植物多样性监测网是中国生物多样性监测和研究网络的10个专项网之一,旨在以植被群系为基本单元,在草原和荒漠主要植被群系的典型地段建立植物模式群落监测样地,长期监测草原和荒漠植物多样性变化。本文从监测布局、监测样地布设、监测指标和数据产出等方面介绍了草原和荒漠植物多样性监测网的工作进展,并提出未来10年草原和荒漠植物多样性监测网的工作重点,即优化监测点的空间分布、推进自动化监测技术的应用、加强生物多样性变化研究。这些措施将有效提升草原和荒漠植物多样性监测网的研究水平和科学服务能力,为生物多样性保护和研究提供关键的数据支撑。

Background&Aims:Focused on the predominant vegetation types in North China and the Qinghai-Tibetan Plateau,namely steppe and desert,this study delves into the unique and abundant biodiversity resources within these regions.The Steppe and Desert Plants Diversity Observation Network is one of the ten branches of the China Biodiversity Observation and Research Network.It endeavors to create permanent plots representing specific plant communities in areas with distinct vegetation alliances.Its objective is to conduct long-term monitoring of plant diversity dynamics at regular intervals Progress:Over the past five years,the Steppe and Desert Plants Diversity Observation Network has achieved significant milestones in monitoring plant diversity within steppe and desert ecosystems.This paper presents an overview of the plan and construction progress,encompassing aspects such as the layout of monitoring sites,plot arrangement,monitoring indicators,and data generation.Prospects:Looking ahead,the Steppe and Desert Plants Diversity Observation Network envisions advancements in three key areas:refining the spatial layout of monitoring sites,constructing an automated monitoring system and conducting research on the dynamics of plant diversity.These initiatives aim to comprehensively elevate the research standards and scientific service capabilities of steppe and desert biodiversity science in China.Additionally,they will furnish essential data support for biodiversity research and conservation efforts.
