Regional agricultural key farming season online visualization prediction method

Abstract

The invention discloses a regional agricultural key farming season online visualization prediction method. The method comprises the following steps that: step 1, a regional agricultural map base is produced through utilizing ArcMap and is issued; step 2, a geographic information processing model of key farming seasons is established, and geoprocessing services are issued; step 3, key farming season regions are drawn; step 4, distance and area measurement and calculation are performed; step 5, the boundaries of the drawn key farming season regions are adjusted; and step 6, a final key farming season visualization result map is determined and outputted. With the method of the invention adopted, the change of farming seasons with time and space can be intuitively demonstrated in a diagram and map-combined manner; and agricultural planting can be arranged more efficiently and reasonably by means of advanced network technologies and geoprocessing technologies. The regional agricultural key farming season online visualization prediction method has the advantages of high efficiency, convenience and visualization.

Description

technical field [0001] The invention belongs to the technical field of regional agricultural production management and meteorological disaster prediction and early warning, and relates to a method for online visual forecasting of key agricultural seasons in regional agriculture. Background technique [0002] In recent years, agricultural meteorological disasters have occurred with high frequency, variety and wide range. Meteorological disasters directly affect agricultural production, and most of them occur during key agricultural seasons. In view of the regional distribution and occurrence characteristics of meteorological disasters, it is particularly critical to guide agricultural production to proceed in an orderly manner, and to successfully complete spring plowing and spring sowing, summer harvesting and summer planting, and autumn harvesting and autumn sowing before the disaster weather comes. [0003] At present, most meteorological services for key agricultural seas...
