| Urban forest has been emphasized at large since it was put forward and used in the investigation report of outdoors recreation resources by USA Kennedy government in 1962 as well as urban forestry was brought forward by Erik Jorgensen of Canada in 1965. Because it plays insubstituted role in city development, many countries stared research and constructed in succession. Although China has began the research in the last two decades in 20C, but its development and construction carried rapidly.This paper put forward a evaluating indicator based on the introduction of current research situation on urban forest from domestic and abroad and preference some evaluating indicators such as forest sustainable management, urban green , urban forest as well as the standard for choosing the garden city , also according to the characteristic of each city , following principles of system, almightiness, independence , conciseness , science , practicality and comparativeness . We also made certain reference value of each index , obtained the weights by using methods both the analytic and hierarchy process and Delphi, and then evaluated the current construction of urban forest in Suqian city (2000, 2003) and Changzhou city (2002) .Results as follows:Evaluations of estimate 0.4973 in 2000, 0.6584 in 2003 of Suqian city , and 0.6623 in 2002 of Changzhou city showed their construction of urban forest were both at the junior level. It also showed that the result of Urban forest not only decided by the quantity ,but also the layout (include the inner and the layout ) .In the evaluating process ,we tried employing the technology of remote sensing and the geography and information system .With Mapinfo software running at the Windows corresponding relations were build up between attribute data and spatial data ,and displayed tremendous superiority in inquiring , statistical analyzing , mapping , and data updating, met the demand the scientific management of urban forest resource .
