摘要

Increasing population and urbanisation drive significant land-use and land-cover changes, disrupting ecological balance and diminishing regulatory ecosystem services. This decline reduces carbon storage capacity, increases air pollution, and intensifies the urban heat island effect. Regulatory ecosystem services, however, provide essential benefits for environmental sustainability and public health, including climate regulation and the maintenance of clean air and water cycles. This study evaluates carbon storage and air quality indicators on the central campus of Niğde Ömer Halisdemir University for 2010 and 2024, with projections for 2038, using the I-Tree Canopy model developed by the United States Department of Agriculture Forest Service. Results indicate that expanding tree and shrub cover substantially enhances both carbon storage and sequestration. Carbon stock increased from 1532.95 tonnes in 2010 to 3394.39 tonnes in 2024, with a projected 6366.44 tonnes by 2038. Annual carbon sequestration rose from 61.04 tonnes to 253.50 tonnes over the same period. Air pollutant removal is also projected to improve across all measured parameters, thereby reducing exposure to harmful pollutants. Ozone removal is expected to rise from 1016 kg in 2010 to 4220 kg by 2038, while PM10 removal increases from 407 to 1692 kg. The findings demonstrate that sustainable green space planning on university campuses can significantly contribute to carbon sequestration, improved air quality, and the mitigation of environmental health risks, supporting broader environmental sustainability and urban planning processes aligned with GreenMetric indicators.
