摘要

The relentless march of urban proliferation is increasingly transforming the ecological tapestry of metropolitan regions, presenting formidable challenges to the enduring sustainability of ecosystem services (ESs). Kamrup Metropolitan District (KMD), the most urbanized district of Assam and the gateway to Northeast India, epitomizes a vital yet understudied region where rapid land-use transformations intersect with ecologically delicate hillscapes and wetlands. This study evaluates the long-term impacts of urbanisation-driven land use/land cover (LULC) dynamics on ecosystem service values (ESV) in KMD from 1990 to 2024, with projections up to 2044. Using multi-temporal Landsat imagery, ESVs were quantified through a benefit transfer approach employing value coefficients proposed by Costanza et al. 1997, with sensitivity analysis applied to assess the robustness of the estimates. Spatial autocorrelation of ESV was examined using Global and Local Moran’s I to identify clustering inequities. The findings reveal a persistent diminution in total ESV from US$ 101.74 million in 1990 to US$ 83.20 million in 2024, with a further projected reduction to US$ 75.98 million by 2044, indicating an overall loss of 25.32%. Forests and wetlands remained the dominant contributors to ESV but experienced the largest absolute losses due to hill cutting, wetland encroachment, infrastructure expansion, and peri-urban sprawl. Regulating services accounted for the majority of the ESV decline. Spatial autocorrelation analysis indicates significant clustering of high ESV in forested hills and river systems, contrasted with low-ESV clusters in highly urbanised cores. This study provides local-scale policy insights to sustainably manage the interactive coercive relationship between urbanisation and ecosystem services.
