Foreword
The development of this standard for the timely, accurate and standardized reflection of the project of returning farmland to forest on the ecological environment changes and economic and social development,
Scientifically and comprehensively evaluate the effectiveness of the project of returning farmland to forest, and provide the basis for the management and decision-making of returning farmland to forest.
Appendix A of this standard is a normative appendix.
This standard is proposed by the State Forestry Administration and centralized.
This standard is interpreted by the National Forestry Administration's Returning Farmland Project Management Center.

Monitoring and Evaluation of Construction Benefit of Returning Farmland to Forest Project
1 Scope
This standard stipulates the method and the monitoring project and the content of the monitoring station for the construction of the returning farmland to forest project, and puts forward the policy of returning farmland to forestry
Evaluation Index of Benefit Monitoring in Construction and Calculation Method of Each Index.
This standard applies to the implementation of the national implementation of the project of returning farmland to forest.
2 monitoring station facilities
The monitoring station should be built in a representative small area with an area of 3km2 ~ 5km2. Locate the monitoring station as needed
Station meteorological station, Mizoguchi hydrological station, slope runoff field, set sand tank, fixed standard, survey sample and other facilities.
2.1 weather station
2.1.1 The setting of the weather station. Select the open and open ground station in the small watershed, and observe the necessity of observing the weather in the weather station
Facilities and equipment, weather stations around the fence set up.
2.1.2 Meteorological station determination of the basic factors. precipitation, evaporation, ground temperature, temperature, humidity, solar radiation, wind speed, wind direction and so on.
2.2 Mizoguchi hydrological station
2.2.1 Mizoguchi hydrological station to establish the location. in the watershed exit selection channel straight, ditch bed stability, there is no tributary waters and the impact of traffic
Where the establishment of Mizoguchi hydrological station 1, to determine the whole river runoff and sediment.
2.2.2 Mizoguchi hydrological station ancillary facilities. hydrological station of the amount of water buildings according to the size of the flow selected triangular 90 ° overflow weir or Barshall test
Streamer.
2.3 slope runoff field
2.3.1 slope runoff field settings. for returning farmland to forest different vegetation recovery model, according to different slope settings, monitoring slope runoff, sediment.
2.3.2 Slope flow field number. each slope surface set up two to three fixed slope runoff field.
2.3.3 slope diameter flow field specifications. specifications for the 5m × 10m or 5m × 20m.
2.3.4 runoff field setting method. laying the runoff field should be long side perpendicular to the contour line, short side parallel to the contour line.
2.3.5 Temporary runoff field setting. The temporary runoff field is used as a supplementary monitoring method for the fixed diameter flow field and can be set according to the requirement. The specification is 5m ×
10 m or 2 m x 5 m or 2 m x 10 m.
2.4 set sand tank
2.4.1 Set the sand tank. In the sandstorm area for different vegetation restoration mode and forest species, set the sand tank, monitor the unit area,
The amount of sand within the sand, sand tank texture for the concrete prefabricated.
2.4.2 Set the number of sand dunes. each vegetation restoration mode and forest species were set up 2 ~ 3 fixed set sand tank.
2.4.3 set sand slot specifications. specifications for the 3m × 0.5m × 0.5m.
2.4.4 Set the sand tank set method. in the layout, according to the local main wind direction, while maintaining the direction of the main wind with the local conditions, will be mixed
The concrete prefabricated material is embedded in the same horizontal plane as the surface.
2.5 fixed standard
2.5.1 Fixed standard setting
In order to monitor the dynamic changes of forest and grass growth and biological productivity in the project of returning farmland to forest, it is necessary to set up fixed standard for location monitoring.
Fixed standard GPS calibration, in the standard four corners under the ground buried 1.2m deep cement pile as a permanent mark.
2.5.2 Fixed number of standards
The monitoring stations should be set to a fixed standard of 3 to 5.
