- Abstract
Based on the forest management inventories in Lushihe Forest Bureau of Changbai Mountains in 1987, 1995 and 2003, and by using ArcGIS and Fragstats spatial analysis software, this paper analyzed the relationships between landscape pattern change and forest management mechanism in the study area at landscape and patch scales. During the study period, the landscape fragmentation degree and heterogeneity in the study area increased. From 1987 to 2003, the patch number increased by 979, while the proportion of the largest patch area decreased from 28.7% to 12.7%. With the change of management strategy, the landscape matrix changed from mixed broadleaved forest matrix in 1987 to compound matrix in 1995. The extent of landscape fragmentation in 1995-2003 was somewhat reduced, compared with that in 1987-1995. During the study period, the mean patch area and edge density of broadleaved mixed forest decreased most, suggesting that natural secondary forest suffered most from human disturbances.
