Integrated ecological index IEV zones PUG

Integrated Ecological Value IEV aggregated by PUG zones. This index is an indicator obtained by the integration of 7 different ecosystem services: climate regulation, dust sedimentation, contaminant retention, porous or permeable surface, groundwater recharging, rainwater infiltration, habitat formation. It varies between 0 and 1. Low values indicate low ecological quality. — The layer is produced with the QGIS AVT_UEI_Calculation plugin from the surface material classification map. For the methodology, see the following scientific article: R. Behling, M. Bochow, S. Foerster, S. Roessner, H. Kaufmann. Automated GIS-based derivation of urban ecological indicators using hyperspectral remote sensing and height information. Ecol. IND., 48 (2015), pp. 218-234, https://doi.org/10.1016/j.ecolind.2014.08.003按PUG分区聚合得到的综合生态价值（Integrated Ecological Value，简称IEV）。该指数为整合7项不同生态系统服务后生成的指标，涵盖气候调节、粉尘沉积、污染物滞留、多孔/透水地表、地下水补给、雨水入渗及生境形成。其取值区间为0至1，数值越低则代表生态质量越差。 本图层基于地表物质分类图，通过QGIS的AVT_UEI_Calculation插件生成。相关研究方法可参阅以下学术论文：R.
