摘　　要：叶面积指数(leaf area index,LAI)通常被定义为植被叶、茎、花、果等组分的总面积与土地面积之比,是生态系统碳循环、水文和气候等模型中不可或缺的重要组成参数,已被广泛应用于森林监测、植被评价和农作物产量预估等。LAI可较好反映森林生长状况,是评价森林健康的良好指标,其不仅影响森林的碳吸收,而且能够通过改变感热与潜热通量比例,直接影响区域乃至全球气候。中国科学院西双版纳热带生态系统研究站(简称版纳站)作为中国生态系统研究网络(CERN)和国家野外科学观测研究站网络(CRERN)成员,严格按照《陆地生态系统生物观测指标与规范》进行监测,获得的数据按照《陆地生态系统生物观测数据质量保证与质量控制》进行严格数据控制。本数据集整合版纳站5个长期监测样地2010–2020年森林植物群落乔、灌、草各层叶面积指数数据,以期为研究热带森林生态系统及碳循环提供科学依据。Leaf area Index(LAI)is typically defined as the ratio of the total area of vegetation,including leaves,stems,flowers,fruits and other components to the corresponding land area.LAI is an indispensable component parameter in ecosystem carbon cycle,hydrological and climate models.It has been widely used in forest monitoring,vegetation evaluation and crop yield estimation.As an effective tool for assessing forest health,LAI can better reflect forest growth.It can not only affect forest carbon absorption,but also directly affect regional and even global climate by changing the ratio of sensible heat and latent heat flux.As a member of the China Ecosystem Research Network(CERN)and the National Field Scientific Observation and Research Station Network(CRERN),Xishuangbanna Tropical Ecosystem Research Station(Banna Station)of the Chinese Academy of Sciences(CAS)conducts monitoring strictly in accordance with the Terrestrial Ecosystem Biological Observation Indicators and Norms.The quality of the observation data is strictly controlled pursuant to the Quality Assurance and Quality Control of Terrestrial Ecosystem Biological Observation Data.In this dataset,we collected the data of leaf area index(LAI)of tree,shrub and grass layers of forest plant communities in five long-term monitoring plots of Banna Station from 20010 to 2020 to provide scientific foundation for the study of tropical forest ecosystem and carbon cycle.
