The present research paper proposes an AHP model based on integrating weight and VORS modelis used to prepare of ecosystem health conditions map in Kalimpong district of West Bengal from 1991 to 2021. In this study, LULC map is prepared based onlandsat-5 (for 1991) and also landsat-8 (for 2021)applyingArcgis 10.3.1.The district is covered by 7 types of LULCclasses such as agriculture fallow land, forest,social forestry, agriculture plantation, build up area, agriculture land and water bodies1. LULC map of 1991 and 2021 were used to prepare ESVs map based on ESVs of biomes, 1997 and 2014 to analysis of spatio-temporal dynamics in ESVs of the district.EH of the district is categorised into five classes in the period of 1991 to 2021. The output results show that about 30.05 % and 23.30 % areas under very good health condition in 1991 are predicted while the areas under very good health conditions are changed to 22.00 % and 22.00 % in 2021 as per used ecosystem services map which prepared based on global coefficient values. This work gives a valuable guide line for conducting sustainable environmental management steps for the district in future.
