Water resource evaluation method based on single factor index method

The invention relates to the technical field of water resource management, in particular to a water resource evaluation method based on a single factor index method, which comprises the steps of acquiring water resource evaluation area information, determining a water resource evaluation range based on the water resource evaluation area information, and collecting water resource related information in the water resource evaluation range, constructing a factor library for water resource evaluation based on the water resource related information; setting an evaluation factor selection logic, selecting an evaluation factor from the factor library for water resource evaluation based on the selection logic, and evaluating the health state of the water resource by applying the selected evaluation factor; a single-factor index method is used as a basic algorithm of the evaluation method, water resource related information is collected to construct a factor library for evaluation, and multi-directional evaluation con
