Evaluation on Application of i-Tree Model in Urban Forest Quantification

i-Tree model was releasedbythe US Department of Agriculture’s Forest Service in 2006, and has been widely used to quantify ecosystem services and benefit values of urban forest. The application of i-Tree model was evaluated in terms of landscape planning, landscape evaluation, comparisons of different models and public participation by VOSviewerof i-Tree related Chinese and English literatures, combined with manual review. Further development and application of i-Tree model were prospected. It is proposed that i-Tree model could beoptimized from the perspectives of moreinternational applications, improving quantitative accuracy, and increasing the types of evaluation indicators.
