Urban forest research is a rising research area. One of the trends of urban forest research is researching urban forest by using landscape ecological methods. Landscape pattern analysis is the basis of urban forest landscape ecological researches. By utilizing RS and GIS technologies and theories and methods of landscape ecology and vegetation ecology, we analyzed the characteristics of the urban forest landscape pattern of Nanjing city, and discussed the ways and methods for urban forest landscape ecological researches. The main content and results of this paper are as follows: (1) Based on the landscape ecological classification principles, two urban forest landscape types and four subtypes were identified; (2) urban forest classification survey was carried out, and urban forest landscape distribution maps and spatial attribution data were obtained by using RS and GIS technologies; and (3) choosing a set of indices of landscape spatial pattern, the characteristics of the urban forest landscape pattern of the study area were quantitatively and qualitatively analyzed. On the basis of these characteristics, we put forward some measures and suggestions for the urban forest landscape planning and construction. We think that the Nanjing urban forest has the following characteristics: proper coverage, higher naturality, higher fragmentation, and intensive disturbance by human activities. We also think that the large landscape patches of high naturality should be strictly protected and the design of landscape corridors of different scales is a key measure for the urban forest to effectively perform its landscape ecological functions.
