2011-2020年川中丘陵区典型人工桤柏混交林凋落物回收量月动态数据集

A dataset of the monthly dynamic litterfall recovery from typical alder cypress mixed forests in the hilly areas of central Sichuan during 2011–2020

森林凋落物的收集与测定是研究森林生态系统结构与功能的重要手段。人工桤柏混交林广泛分布于亚热带川中丘陵区,是长江上游防护林体系工程的典型模式之一。在对盐亭站人工桤柏混交林样地的森林凋落物长期定位观测基础上,本文整理了2011–2020年典型人工桤柏混交林凋落物回收量月动态数据,凋落物按叶、枝、果(包括脱落的种子)分组,形成样地和样点的凋落物月动态数据,用户可以按照采集时间和凋落物器官进行数据检索。利用本数据可对人工桤柏混交林的凋落物动态特征研究分析;本数据集可为长江上游防护林森林生态系统的林分特征、物质循环及其稳定性等研究提供数据支持。

The collection and measurement of forest litterfall is an important tool for studying the structure and function of forest ecosystems.Widely distributed in the subtropical hilly area of central Sichuan,planted alder cypress mixed forests are one of the typical models of the upper Yangtze River protection forest system project.Based on the long-term station-fixed observation of the forest litterfall in the sample plots of the mixed forests of artificial alder at Yanting Station.We compiled in this dataset the monthly dynamic data of litterfall recovery in typical mixed forests of artificial alder from 2011 to 2020,with the litters grouped by leaves,branches and fruits(including shed seeds),so as to obtain the monthly dynamic data of forest litterfall in the sample plots and sample points.The data can be retrieved in terms of specific collection time and organs.The dataset can be used to analyze the dynamic characteristics of the planted alder mixed forests and support the study on forest structure,material cycling and stability of the forest ecosystem in the upper Yangtze River protected forests.
