摘要:
气溶胶污染对人居环境健康构成了严峻挑战,绿地是 缓解气溶胶污染的重要有机生命体。既往研究集中于二维形态绿 地与气溶胶的相关研究,对三维绿量景观格局与气溶胶空间规 律的定量化研究很少。基于遥感影像提取AOD数据并结合三维 绿量模型得到三维绿量,并计算三维绿量景观指数,然后运用 相关分析和回归分析定量探讨了两者的相关和回归规律,进而 基于地理加权回归探讨了两者的空间规律特征。研究揭示了: 1)CA、PLAND、LPI、COHESION、AI的增加对降低气溶胶 浓度具有核心作用,PD、LSI的增大对气溶胶浓度增加具有核心 的促进作用;2)气溶胶与各指数因子都属于非线性关系,CA、 PLAND、LPI与气溶胶浓度呈反比关系,而PD、LSI与气溶胶 浓度呈正比关系,三维绿量调控气溶胶浓度的协同作用规律模 型为Y=1.154 7?0.000 1CA?0.007 2PLAND+0.029 1LSI; 3)缓解气溶胶污染的三维绿量核心景观指数为CA、PLAND、 LSI,其阈值分别为602、87.61和4.56,并提出阈值调控策 略。旨在为风景园林规划设计提供参考。

The Influence of Three-dimensional Green Biomass Landscape Pattern on Aerosol Based on Remote Sensing Inversion
YUE Feng,FU Fan,DAI Fei,ZENG Hui
Abstract:
Aerosol pollution poses a serious challenge to the health of human settlements, and green space is an important organic organism to mitigate aerosol pollution. Previous studies focused on the correlation between two-dimensional green space and aerosols, and few quantitative studies on three-dimensional green landscape pattern and aerosol spatial law. In this paper, AOD data is extracted based on remote sensing images and combined with the threedimensional green quantity model to obtain the three-dimensional green quantity, and the three-dimensional green quantity landscape index is calculated. Then, the correlation and regression laws of the two are quantitatively discussed using correlation analysis and regression analysis, and then the spatial law characteristics of the two are discussed based on geographical weighted regression. The research reveals that: 1) the increase of CA, PLAND, LPI, COHESION, AI plays a key role in reducing aerosol concentration; The increase of PD and LSI plays a key role in promoting the increase of aerosol concentration; 2) The relationship between aerosol and each index factor is nonlinear. CA, PLAND, LPI are inversely proportional to aerosol concentration, while PD, LSI are proportional to aerosol concentration. The synergetic model of three-dimensional green amount regulating aerosol concentration is Y=1.154 7?0.000 1CA?0.007 2PLAND+0.029 1LSI; 3) The core landscape indexes of three-dimensional green quantity to mitigate aerosol pollution are CA, PLAND, LSI and their thresholds are 602, 87.61 and 4.56 respectively, and threshold control strategies are proposed. The research aims to provide reference for landscape architecture planning and design.
