2007~2008年贵州省龙里地区森林生态调查数据库

本数据包括对贵州龙里生态园的三种典型森林生态系统类型的植被进行生态调查，针阔混交林、马尾松、灌丛三种典型森林生态系统类型的植被调查，而每种类型的森林生态系统植被调查数据表中含有总表、草本层、乔木层以及多个灌木层样地的生态调查数据。主要包括如下指标：种名、株高、灌丛灌径/丛径、生长势、乔木胸径、冠幅、草本层盖度、样地面积、海拔、坡向、坡度、经度、纬度、乔木层盖度、灌木层盖度、枯落物层高度、活地被层高度、群落总盖度15个指标。数据收集时间为2007年第一次收集，2008年更新收集数据。数据采集地点贵州龙里研究区（经度：107°01’09"E；纬度：26°27’8.1"N；海拔：1205米）。该数据的主要生产方法包括两方面，第一是对样地样方内的植被进行野外调查，实际测量和采样，第二是采集植物标本，回实验室进行标本鉴定。在加工生成数据表时，剔除了一些明显误差数据。

This dataset comprises ecological vegetation surveys of three typical forest ecosystem types in Longli Ecological Park, Guizhou Province: mixed coniferous-broadleaf forest, Pinus massoniana forest, and shrubland. For each of these three ecosystem types, the corresponding survey data table includes comprehensive summary data, as well as survey records from sample plots of the herb layer, tree layer, and multiple shrub layer plots.

A total of 15 indicators are covered in the surveys: species name, plant height, shrub diameter/clump diameter, growth vigor, diameter at breast height (DBH) of trees, crown width, herb layer coverage, plot area, elevation, slope aspect, slope gradient, longitude, latitude, tree layer coverage, shrub layer coverage, litter layer height, living ground cover height, and total community coverage.

The data was first collected in 2007, and updated with supplementary data in 2008. All fieldwork was conducted in the Longli research area, Guizhou (longitude: 107°01'09" E; latitude: 26°27'8.1" N; elevation: 1205 m).

The primary methods for generating this dataset consist of two parts: first, carrying out field investigations, on-site measurements and sampling for vegetation within the designated sample plots; second, collecting plant specimens and conducting laboratory-based specimen identification. During the data processing and table compilation stage, any obviously erroneous data were excluded from the final dataset.
