摘      要：Landscape conversion becomes a continuous process in a natural landscape for any strategic *** a forest landscape mosaic,the conversion from non-forest land to forest land implies a constructive *** bio-geographic processes are enriched and developed when the land was converted to forest land in a given landscape *** present study evaluated how the increased forest cover improves the ecological quality of forest in Jhargram District of West Bengal State,India,from 1985 to *** quality of forests includes dominance,fragmentation and connectivity,which are the basis ecological indicators of habitat *** address this issue,we extracted forest cover maps of 1985 and 2015 from land use/land cover classification.A grid framework was overlaid on these forest cover maps for patch-matrix model *** landscape ecological indices were used for the measurements of forest landscape quality in 1985 and *** a simple linear regression model was used to compare the ***,forest cover increased in Jhargram District from 1985 to *** comparison of measurement indices depicts that although only a small amount of land was changed into forest land in the study area,this small change has greatly improved the structural compositional quality of the forest *** with 1985,the forest land area increased by about 6930.56 hm^(2) in *** increased forest cover improved the basic landscape ecological characters,such as inter patch connectivity,forest core area,forest habitat dependence,forest habitat dominance and forest edge *** a result,the ecosystem function in Jhargram District has been improved,which again attracts wildlife and enriches biodiversity.
