This study aims to determine the impact of land use changes on air quality at the largest conurbation area in Malaysia, Kuala Lumpur Extended Mega Urban Regions (KLEMUR) from 2000 to 2015. Statistical and geostatistical analysis were used to analyse air quality and land use data. The results showed that only the daily average concentration of PM₁₀ at several stations exceeded the concentration suggested by the World Health Organization (WHO). All air pollutants measured showed a rising trend, with the exception of the SO₂. The land use trends during the 16-year research period showed an increase in built-up lands (4.0 %) and a reduction in vegetation (3.3 %) and water bodies (2.3 %) which caused the spatial distribution of air pollutants to expand from the centre of KLEMUR to the north and south. Principal Component Analysis (PCA) demonstrated that 52.68 % of the air pollution was influenced by vehicular and industrial emissions given that the strong factor loadings (>0.70) consisted of NO, NO₂, NO_x, CO and SO₂. The land use changes have a significant impact (p < 0.10) on air pollution in KLEMUR since NO, NO₂, NO_x, CO and SO₂ were positively correlated with the built-up lands and negatively correlated with vegetation and water bodies.

这项研究旨在确定2000年至2015年马来西亚最大的城市化地区，吉隆坡扩展超级城市地区（KLEMUR）的土地利用变化对空气质量的影响。使用统计和地统计分析来分析空气质量和土地利用数据。结果表明，只有几个站点的PM ₁₀每日平均浓度超过了世界卫生组织（WHO）的建议浓度。除SO ₂外，所有测得的空气污染物均呈上升趋势。在为期16年的研究期内，土地利用趋势显示，已建成土地增加（4.0％），植被减少（3.3％）和水体（2.3％），这导致空气污染物的空间分布从KLEMUR的中心位于北部和南部。主成分分析（PCA）表明，由于强大的因子负荷（> 0.70）由NO，NO ₂，NO _x，CO和SO _2组成，因此52.68％的空气污染受车辆和工业排放的影响。 由于NO，NO ₂，NO _x，CO和SO _2的变化，土地利用变化对KLEMUR的空气污染有显着影响（p <0.10）。 与耕地呈正相关，与植被和水体呈负相关。
