LY/T 2900-2017Regulation for the construction of long-term observation station of wetland ecosystem (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces LY/T 1708-2007 "Technical Requirements for Construction of Wetland Ecosystem Positioning Research Station", and LY/T 1708-2007 the main technical changes are as follows.

--- Modify the standard name "Technical Requirements for the Construction of Wetland Ecosystem Positioning Research Station" to "Wetland Ecosystem Positioning Observation Research Station" Construction regulations";

--- Revised scope, normative references, definitions and terminology;

--- Removed the guiding ideology, naming rules and investment estimates;

--- Added equipment, facilities and facilities suitable for the positioning and observation of wetland ecosystems.

This standard was proposed by the Chinese Academy of Forestry.

This standard is under the jurisdiction of the National Wetland Protection Standardization Technical Committee (SAC/TC468).

This standard was drafted. Wetland Research Institute of Chinese Academy of Forestry, Ecological Positioning Observation Network Center of the State Forestry Administration, National Forestry Bureau of Wetland Protection Management Center, Northeast Normal University, Institute of Tropical Forestry, Chinese Academy of Forestry, and China Academy of Forestry with a forestry research institute.

1 Scope

This standard specifies site selection, infrastructure equipment construction, laboratory construction, wetland meteorology for wetland ecosystem positioning observation and research stations.

Construction of observation facilities and equipment, construction of wetland hydrological and water quality observation facilities, construction of observation facilities for wetland soils and sedimentary physical properties, the contents and technical indicators of the construction of wetland biological observation facilities and the construction of remote data collection equipment.

This standard applies to the national wetland ecosystem positioning observation and research station.
