Introduction

In recent years, the number of forest ecological stations affiliated to the China Forest Ecosystem Positioning Research Network (CFERN) of the State Forestry Administration has increased dramatically. The observation techniques and methods are constantly emerging, and the equipment is extensively updated. In order to adapt to the long-term positioning observation of forest ecosystems, new observation indicators With the needs of observation instruments, it is urgent to develop more systematic and accurate field observation methods to guide the daily scientific research and observation work of forest ecological stations. This standard has the following characteristics. --- The idea of using systematic observation methods is different from the previous method of determining observation methods according to single observation factors or single ecological factors. Traditional mode --- Starting with 28 key scientific issues in the long-term positioning of forest ecosystems, and guiding the field observation methods with scientific issues Continuity and integration; --- Inheriting the past and starting, and the forestry industry standard of the People's Republic of China "forest ecosystem positioning observation index system" (LY/T 1606- 2003) before and after the convergence, covering all 94 observations; --- is a field system observation method system specifically for long-term continuous positioning research of forest ecosystems, basically does not involve experiments Indoor physical and chemical analysis content; --- Full reference to the latest developments in the field of forest ecosystem observations at home and abroad, while at the same time from CFERN Starting from the actual situation of the field observation capability of the forest ecological station, the practicality and advanced nature of the field observation method are organically combined. Long-term positioning observation method of forest ecosystem

1 Scope

This standard specifies the long-term continuous positioning observation methods and technical requirements for forest ecosystems. This standard applies to long-term continuous positioning observation of forest ecosystems, and is also applicable to other related forest ecological monitoring.
