By clearly defining the forest management unit level city as the research object, summarizing and analyzing the situation of urban forest development at home and abroad and index system of sustainable urban forest management,combining the urban forest management conditions in Guangzhou,we used the target method and Delphi method to set up an index system of sustainable urban forest management based on forest unit level,which contains thirty indicators at three levels. Then the current condition of Liuxihe National Forest Park,Dalingshan Forest Farm and Dafushan Forest Park have been evaluated with the index system. The total scores were 0.860 2,0.876 2 and 0.874 7,belonging to a state of sustainable management. On the basis of analyzing the factors restricting the sustainable forest management in Guangzhou,we put forward some countermeasures for sustainable urban forest management.
