In particular, for example, the method of the present invention can be used for self-inspection of the park or for the management of the park by relevant departments, and the recommended development direction is planned according to the total score of the park and the score of each specific item; for example, if the total score of a park is higher than 85 points, it can be considered to be rated as a demonstration park for reference by other parks; for example, if a park adopts this method for self-inspection, among the seven major categories of indicator scoring items, the score percentage of two categories is too low, then it can be considered to focus on strengthening the optimization and upgrading of these two aspects in the future, so as to gradually develop into a zero-carbon park; thus, by promoting and implementing this method, it is expected to achieve rapid promotion of green and low-carbon transformation and development of various parks, which is of great significance to social development and ecological construction. In addition, the method of the present invention can be implemented through computer executable instructions, which are stored in computer storage media, thereby forming an evaluation system for determining whether it is a low-carbon park or a zero-carbon park, such as a software program, etc.; including an information acquisition module for obtaining the park situation, a data processing module for performing calculations on the acquired information, and a display module for displaying the results in text, graphics, or tables, etc.
