The embodiment of the invention discloses a method for intelligently planning a line path, which comprises the following steps of: 100, adding engineering actual constraint conditions of multiple levels on the basis of an initial line calculated by using a shortest path algorithm; step 200, in combination with topographic analysis and spatial analysis of the GIS, optimizing a line path scheme meeting requirements according to constraint conditions; step 300, taking a starting point of line connection as a current path, and taking a regional environment grade score in the path as a basis for judging the quality of the line; step 400, when a plurality of combined solutions appear according to the above steps, performing line selection recommendation on each solution according to a real line;and step 500, finally calculating the total score of all factors of the whole line according to the weight sum. According to the method, the forward scoring method is combined with the actual road condition to fully consider the characteristics of line engineering, various key parameters related to power transmission line path design can be provided, the method has a certain reference value, convenience is brought to path planning of designers, and the cost performance is high.
