Grassland meteorological monitoring and evaluation method
1 Scope
This standard specifies the definition, project and method of grassland meteorological monitoring and evaluation.
This standard applies to the grassland growing season meteorological monitoring and evaluation.
2 Terms and definitions
The following terms and definitions apply to this document.
2.1
Grassland meteorological monitoring evaluation grasslandmeteorologicalmonitoringandevaluation
Using meteorological data of grassland, remote sensing and ecological observation, the effects of grassland meteorological conditions, vegetation growth, vegetation coverage, grass yield, grassland
State quality and other monitoring and evaluation.
2.2
Grassland vegetation growth meteorological condition index meteorologicalconditionindexofgrasslandvegetationgrowth
Quantitative values reflecting the meteorological conditions favorable to the growth of grassland vegetation, calculated by meteorological factors such as light, temperature and water, are determined according to their size
The meteorological conditions of grassland vegetation growth favorable.
2.3
Grassland vegetation coverage grasslandvegetationcoverage; GVC
Per unit area of grassland vegetation vertical projection area as a percentage of surface area.
[NY/T 1233-2006, Appendix L.1.37; QX/T.200-2013, Definition 6.13]
2.4
Grassland vegetation growing grasslandvegetationgrowthcondition
Pros and cons of grassland vegetation growth. Generally compared with the same period in recent years (usually nearly 5 years) or a year (usually the previous year)
expression.
2.5
Grassland net primary productivity netprimaryproductionofgrasslandvegetation
Grassland vegetation per unit area in a certain period of time (usually in Japan, the month, season, year or re-green to a certain day) by photosynthesis of organic matter
Subtracting the total amount of organic matter remaining after consumption of self-sustaining respiration [measured in terms of carbon (C)].
Note. The unit is grams per square meter (g/m2).
2.6
Aboveground biomass of grassland vegetation
Current annual biomass of all plants on the ground at a given time per unit area of grassland, including vegetative parts, litter and litter.
Note. The unit is kg per hectare (kg/hm2).
[NY/T 1233-2006, Appendix D.5.1 and Appendix L.1.33]
2.7
Edible forageratio
The proportion of pasture dry matter available to livestock for a given period of time (usually years) per unit area of grassland to total dry matter of grassland vegetation.
