2010-2020年西双版纳地区森林叶面积指数数据集
Listed in ScienceDB
Leaf area index (LAI) is usually defined as the ratio of the total area of vegetation leaves, stems, flowers, fruits and other components to the land area.
Description
It is an indispensable and important component parameter in ecosystem carbon cycle, hydrology and climate models. It has been widely used in forest monitoring, vegetation evaluation and crop yield estimation.
Lai can better reflect forest growth and is a good index to evaluate forest health. It can not only affect forest carbon absorption, but also directly affect regional and even global climate by changing the ratio of sensible heat to latent heat flux. Xishuangbanna tropical ecosystem research station of Chinese Academy of Sciences (hereinafter referred to as Banna station), as a member of China Ecosystem Research Network (CERN) and national network of field scientific observation and research stations (crern), conducts monitoring in strict accordance with terrestrial ecosystem biological observation indicators and specifications, and obtains data in accordance with quality assurance and quality control of terrestrial ecosystem biological observation data Carry out strict data control.

This data set integrates the leaf area index data of tree, shrub and grass layers of forest plant community in five long-term monitoring sample plots of Banna station from 2010 to 2020, in order to provide a scientific basis for the study of tropical forest ecosystem and carbon cycle.
