2007年6月龙里生态调查表-马尾松

包含12个表：总表、草本层、乔木层及9个灌木层。总表包含了样地的草本层盖度、枯落物层高度、活地被层高度；草本层包括了样地草本层的株高、盖度及生活力等；乔木层包括了样地马尾松和杉木的株高、胸径及生活力等；9个灌木层表格包括了9个样地的灌木的冠径丛径比值。数据收集时间为2007年5月，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）。本实验严格按照仪器操作规范进行观测和数据采集，实验操作规范，科学建立模型，利用SPSS、Excel等进行数据统计分析，在加工生成数据表时，剔除了一些明显误差数据。

This dataset consists of 12 tables: a general table, herb layer table, arbor layer table, and 9 shrub layer tables. The general table records the herb layer coverage, litter layer height, and living ground cover height of the sampling plots. The herb layer table contains the plant height, coverage, vitality, and other relevant indicators of the herb layer in the plots. The arbor layer table includes the plant height, diameter at breast height (DBH), vitality, and other related metrics of *Pinus massoniana* and *Cunninghamia lanceolata* in the sampling plots. The 9 shrub layer tables respectively document the crown diameter to clump diameter ratio of shrubs in the 9 corresponding sampling plots. The data was collected in May 2007 at the Longli Research Area in Guizhou, China, with geographic coordinates of 107°01'09" E, 26°27'8.1" N, and an elevation of 1205 meters. This experiment strictly adhered to instrument operation specifications for observations and data collection. Standard experimental protocols were followed, and scientific models were established. Statistical analyses were conducted using software such as SPSS and Excel. Obvious erroneous data were eliminated during the data processing and table generation phases.
