Affected by the clarity and completeness of the collected data of the urban garden ecological landscape,the traditional greenness perception measurement method has the problems of low measurement accuracy and long dynamic update. Therefore,in this paper,we propose a dynamic measurement method for the perception of greenness of urban garden ecological landscape.This method constructs the greenness perception dynamic measurement index system from the two aspects of the green coverage rate and greenness degree of the ecological landscape.Multi-source remote sensing technology is used to collect urban garden ecological landscape data.On this basis,the green area in the landscape data and the perceived greenness characteristics are extracted,and then, combined with the growth state of the ecological landscape,the greenness change rule is determined. Finally,the perceived greenness characteristic results are substituted into the constructed measurement index system,and the dynamic measurement results of ecological landscape greenness perception are output.By comparing with traditional measurement methods,it is concluded that the measurement error of the designed dynamic measurement method is reduced by 0.02,and the dynamic update time is effectively shortened.
