Power transmission line intelligent line selection method based on adaptive node optimization ant colony algorithm

The invention relates to a power transmission line intelligent line selection method based on an adaptive node optimization ant colony algorithm, and the method comprises the steps: determining environmental factors based on a geographic information system, building a hierarchical analysis model, and quantifying the environmental factors; based on a GIS grid map, dividing a geographic space into a regular matrix composed of a plurality of square units, and combining a hierarchical analysis model to obtain the power transmission line construction cost of each basic area, so as to obtain the total cost of a route; and according to the total cost of the route and the GIS grid map, intelligent route selection is carried out through an adaptive node optimization ant colony algorithm, and an optimal route is obtained. Compared with a traditional ant colony algorithm used for intelligent line selection, the ant colony algorithm used in the invention is additionally provided with adaptive adjustment, local variation
