Organisms are the core components of ecosystems, the real implementers of ecosystem functions, and the direct embodiment of ecosystem structure and function: Therefore, long-term monitoring of biological factors is the core content of long-term monitoring of ecosystems: According to a unified design, high-quality data are obtained through long-term monitoring of important parameters of the biological community status and key habitat factors in the ecosystem: High-quality, standardized and comparable data on the dynamics and changes of biological communities can reveal the changes in the structure and function of major ecosystems in my country: The process and mechanism of ecosystem conservation and its relationship with environmental change and human activities, as well as the ways and methods for sustainable use of ecosystems are provided: Serve: Specification for long-term monitoring of terrestrial ecosystem organisms

1 Scope

GB/T 43858-2024 is the Chinese specification for long-term biological monitoring of terrestrial ecosystems, the discipline behind the national ecological observation network. Long-term ecological monitoring has a requirement that ordinary survey work does not: the measurements have to remain comparable across decades and across sites run by different institutions, which means the plot layout, the sampling design and the observation methods must be fixed in advance and then not changed. The standard sets the objectives and principles of long-term biological monitoring, then the establishment and management of monitoring plots in detail, the plot types, their layout, the rules for setting a plot, its area, its internal arrangement, the sampling design within it and the recording of the site conditions; and then the observation content and methods for the biological components, the vegetation composition, structure and productivity, the animal and microbial communities and the phenological observations, together with the sampling frequency, the data recording and quality control and the management and archiving of the resulting data series. It took effect on 25 April 2024.

This document establishes the normative system, objectives, and principles for long-term monitoring of terrestrial ecosystem biomes, and specifies the establishment and management of sample sites, monitoring Monitoring content, monitoring indicator system, monitoring methods and monitoring data content and quality control: This document is applicable to long-term positioning ground surveys at the sample and regional scales in biomes of forest, grassland, desert, wetland and farmland ecosystems: Monitoring is not applicable to inland waters, cities and other ecosystems:
