A Systematic Monitoring and Evaluation Method for the Functional Diversity of Urban Forest Stands

This application discloses a method for systematically monitoring and evaluating the structural and functional diversity of urban forest stands. It identifies the plant type by analyzing the ratio of leaf to leaf root length among different plants, combined with pigment information of plants of the same type. The ratio of leaf to leaf root length is a prominent feature of plant leaves, and identifying this feature through binarized images is fast and accurate. However, identifying plant types solely based on the ratio of leaf to leaf root length or plant pigment information can lead to low accuracy because some plants have similar ratios, and different plants may have similar pigment information. This application combines these two features, using the ratio of leaf to leaf root length and plant pigment information to comprehensively determine the plant type, thus greatly improving the comprehensiveness of the features and increasing the accuracy of identification.
