The invention relates to a geographic element networking observing method and a geographic element observing method. The geographic element networking observing method and the geographic element observing method are able to solve the problem that the existing networking observing method is not possessed of universality, and the problem that the existing geographic element observing technique performed by using a probe cannot represent the earth surface type of an experimental area or its cost is high due to unscientific layout of sampling points. The geographic element networking observing method comprises the following steps: obtaining geographic element image data of a preset sample point in a preset sample zone to be performed with geographic element observing by means of a satellite remote sensing device; processing the geographic element image data, and obtaining the geographic element data of the sample point. The geographic element observing method comprises the step of obtaining the geographic element data of the preset sample point in the preset sample zone to be performed with geographic element observing by means of a probe buried at the underground. The geographic element networking observing method and the geographic element observing method are applicable to the occasion required to carry out the geographic element observing.
Description
technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a geographical element network observation method and a geographical element observation method. Background technique [0002] It is of practical significance to conduct observations of geographical elements in regions that affect the climate of other regions. For example, the Qinghai-Tibet Plateau, which profoundly affects the atmospheric circulation, energy, material and water cycles, and climate of the Qinghai-Tibet Plateau and nearby areas through topographical dynamics and thermal effects, is a climate-sensitive area that affects drought and flood disasters in East Asia and early warning of disaster weather The upstream strong signal critical region. The probe can be used to carry out the observation of soil temperature and humidity in the Qinghai-Tibet Plateau region. However, the existing soil temperature and humidity observation technology using probes o...
