The invention discloses a canopy conductance and meteorological variable correlation evaluation method and system, and the method comprises the steps: dividing a research time period into a plurality of sub-time periods, and determining the canopy conductance of a research crop in each sub-time period; acquiring a plurality of pieces of meteorological variable information of each sub-period, wherein each piece of meteorological variable information has a hysteretic relationship with the canopy conductance; and according to the canopy conductance and meteorological variable information of each sub-period, constructing a fitting relationship between the canopy conductance and the meteorological variable, and obtaining a correlation result between the canopy conductance and the meteorological variable. According to the method, the relationship between the canopy conductance and the meteorological variable can be clearly obtained, so that the influence of the canopy conductance on the meteorological variable can be obtained according to the canopy conductance, and the irrigation mode which can only achieve the optimal irrigation effect and the lowest meteorological environment influence rate can be quickly and accurately obtained.
Description
technical field [0001] The invention discloses a method and system for evaluating the correlation between canopy conductance and meteorological variables, belonging to the technical field of agricultural planting. Background technique [0002] Farmland ecosystem refers to the use of the relationship between biological and abiotic environments and between biological populations in the crop-centered farmland, through reasonable ecological structure and efficient ecological function, to carry out energy conversion and material circulation, and A complex of material production according to the needs of human society. It is a major sub-system in the agricultural ecosystem, and it is an ecosystem domesticated by humans. [0003] The environmental components of farmland ecosystem include natural environment components and artificial environment components. The components of the natural environment are parts inherited from the natural ecosystem, but they are all regulated and cont...
