The invention aims to provide a mountain building green low-carbon technology cost-benefit evaluation method based on
matter element extension, and belongs to the technical field of
green building cost-benefit evaluation. An evaluation
index system covering six dimensions of land saving, material saving,
water saving, energy saving, indoor environment and operation management is constructed; the incremental cost and benefit of the green low-carbon technology are estimated, a subjective weight is determined by adopting a G1 method, an objective weight is determined by adopting an
entropy weight method, and a comprehensive weight is obtained through game theory combination. The method comprises the following steps: dividing evaluation characteristics into a
basic level, a first-star level, a second-star level and a third-star level by utilizing a
matter element extension evaluation model, determining a classical domain, a node domain and matter elements to be evaluated, calculating correlation degree and comprehensive correlation degree, and finally determining the level of an evaluation index. The invention provides a scientific and comprehensive evaluation method for the
cost benefit evaluation of the green low-carbon technology of the mountain building, fills up the research blank in the field, and promotes the application of the green low-carbon technology in the mountain building.
