In order to explore the evaluation system of lights cape under forest in the urban park, an evaluation system of lights cape under forest in the urban park was constructed, which was composed of physical factors, psychological factors and spatial factors and the corresponding 12 indexes affecting the lights cape based on Grey Statistical Theory and Analytic Hierarchy Process. The results show that: 1) Psychological and physical factors are the dominant influencing indexes in the evaluation system, and the weight accounting of these factors is more than 70%. 2) The total weight of illumination uniformity is higher than other evaluation indexes. 3)The important indicators and sub-important indicators that affect the evaluation of lights cape under forest in the urban park are as follows: illumination Uniformity, satisfaction of lights cape, audio-visual coordination, sky View Factor, daylight factor under forests, perception of privacy, perception of security and clear bole height, etc. The evaluation system is expected to provide theoretical basis and effective methods for the future study in urban light environment.
