Forest landscape pattern is the core ot the research ot forest landscape ecotogy, r orest lanuscapc pattern was analyzed systematically by using GIS technology and collecting patch characteristic index, landscape heterogeneity and driving force of landscape pattern change of landscape and recreation forests, which based on the basic information. The results showed that the landscape types＇ number of Nanshan scenic spot in Shouning during the study period had not changed while the characteristic value of different landscape types had significantly changed. Landscape diversity index, degree of fragmentation and evenness index were rising while the dominance index was being down after the landscape heterogeneity was analyzed. More over the change characteristics of different landscape patches were different.
