A spatio-temporal dataset of forest mensuration for the analysis of tree species structure and diversity in semi-natural mixed floodplain forests

We performed replicated, repeated-measures data of height, diameter and vitality at tree level to allow analysis of spatial and temporal structure and diversity in a semi-natural mixed floodplain forest in Italy. Three inventories were performed in 1995, 2005 and 2016 in three ~1 ha plots with varying soil moisture regimes. The use of replicated, repeated-measures data rather than chronosequences allows the examination of true changes in spatial pattern processes through time in this forest type.

本研究针对意大利一处半自然混生泛滥平原森林，采集了单木水平的重复测量数据，涵盖树高、胸径与林木活力三项指标，用于分析该森林的空间结构、时间动态与群落多样性。研究分别于1995年、2005年及2016年，对三块面积约1公顷、土壤湿度条件各异的样地开展了三次森林调查。相较于采用时空替代序列（chronosequences）的研究范式，本研究使用重复布设的长期重复测量数据，能够精准解析该森林类型的空间格局过程随时间推移的真实变化。
