Beschreibung
Zusammenfassung:	The invention relates to a profile area soil moisture measurement method and system, and belongs to the technical field of soil moisture measurement. A neutron collection system is arranged in a to-be-detected area to obtain near-ground neutron information in the to-be-detected area, at least one detection point is arranged with the neutron collection system as the center, each detection point is provided with a soil moisture detector, and the soil moisture content of each layer of each detection point in the to-be-detected area is synchronously obtained. And inverting the soil moisture content of the to-be-detected area by using the fast neutron intensity, obtaining a calibration coefficient according to the soil moisture content of the to-be-detected area, the soil moisture content of each layer obtained by each detection point and the depth weight of each layer, and calibrating the soil moisture content of each layer according to the calibration coefficient. The method can accurately measure the soil moist
