Abstract

Abstract: Biodiversity is one of the key elements to maintain the multifunctionality and stability of terrestrial ecosystems,and is fundamental to the realization of grassland ecosystem services and functions. Temperate meadow grasslands are located in the transition zone between semi-humid and semi-arid region,and their dominant populations are sensitive to changes in water and temperature;therefore,exploring the pattern of species diversity and productivity of temperate meadow grassland plant communities would have guiding significance for the production and management of natural grasslands in Northern China. The meadow grassland area of western Jilin,China,Changling County of Jilin Province was selected as the research object with typical sampling plots survey method,and the spatial pattern of grassland productivity and community diversity indicators was analyzed in 2022. The main conclusions are as follows:the productivity of natural grassland in Changling County is higher as a whole,and according to the grassland evaluation standard,the productivity of 19 sampling plots within 25 sampling plots reaches level 4 or above;the diversity,evenness and dominance of natural grassland communities in Changling County are higher;the diversity of dominant species of close to half of sample plots of temperate meadow grassland in Changling County is similar to that in the protected area,indicating that the effect of natural grassland restoration program in Jilin Province is gradually appearing in recent years. This indicates that the effect of the natural grassland restoration program in Jilin Province in recent years is gradually appearing. This study will be helpful for rational utilization and adaptable management of meadow grassland.

Key words: Temperate meadow grasslands, Changling county, Grassland productivity, Biodiversity, Space pattern

摘要： 生物多样性是维持生态系统多功能性和稳定性的关键要素之一，是草地生态系统服务与功能维持的根本。温性草甸草原位于半湿润与半干旱的过渡区，其草地植物群落特征对水热变化敏感，探讨其草地群落生产力和物种多样性的特征及影响因素，对北方天然草地生产与管理具有指导意义。本研究选择吉林省长岭县为研究对象，采用典型样地调查法，分析了2022年该区草原生产力和群落多样性指标的空间格局。结果表明：长岭县内天然草原生产力整体较高，按照草地评价标准，25个样地内19个样地的生产力均达到4级以上；长岭县内天然草原群落多样性、均匀度和优势度均较高；接近半数样地的优势物种多样性与保护区内相近，说明近年来吉林省天然草原修复项目效果正在逐步显现。本研究也为温性草甸草原适应和缓解全球气候变化的影响等实践应用提供补充与参考。
