摘要:

模式植物群落是指能够反映某种植被分类单元基本特征, 并可作为准确描述该植被类型“标准”的典型植物群落。草原模式植物群落监测是中国生物多样性监测与研究网络——草原/荒漠植物多样性监测网的核心内容, 已初步确定了一套监测方法。本文应用这套方法分别建立了克氏针茅(Stipa krylovii)群系和百里香(Thymus mongolicus)群系模式植物群落监测固定样地, 作为中国生物多样性监测与研究网络——草原/荒漠植物多样性监测网的样例。介绍了这两个模式植物群落监测样地选取与设置的过程、群落调查方法和数据分析结果。通过实际观测和案例分析, 验证了“中国草原/荒漠植物多样性监测网模式植物群落监测方案”中监测方法的可行性, 同时根据监测中出现的问题, 提出了模式植物群落样地、监测频率和监测日期的选择原则, 以及监测过程中的操作规范等, 完善了模式植物群落监测内容、方法和指标体系的建议, 为开展草原模式植物群落监测提供了可借鉴的实例与技术储备。

Abstract:

A typical plant community, which reflects the basic community characteristics of a vegetation classification unit, can be designated as a standard unit for describing a distinct vegetation type. Providing observations of typical plant communities in the steppe is the main function of the Steppe and Desert Biodiversity Observation Network and Sino Biodiversity Observation Network (Sino BON). Methods of observing typical plant communities have been published. We set up permanent observation plots of Form. Stipa krylovii and Form. Thymus mongolicus as examples during the summer of 2017. Observation methods were applied and validated, and included stand selection and plot design, vegetation surveys, and data analysis. Based on practical observations and analysis, we demonstrated the applicability of the observation methods presented in the previously published paper “Methods of observing typical plant communities in the Steppe and Desert Biodiversity Observation Network, Sino BON”. Suggestions for the improvement of the content, methods, and indices of observation were presented with respect to problem areas. We aim to provide a case demonstrating the applicability of the standard methods for future observations.
