Blue-Green Space Changes of Baiyangdian Wetland in Xiong’an New Area, China

As a regulator of ecological environment, Baiyangdian Wetland is in pivotal position constructing the blue-green space (BGS) Xiong’an New Area China. This study aims to reveal spatiotemporal changes BGS from 2016 2021. It uses Google Earth Engine (GEE) calculate NDVI and NDWI based on Sentinel-2 Satellite remote sensing data extracts by classification model driven NDWI. Moreover, land-use transfer matrix landscape pattern indices are applied for evaluating wetland. According results, vegetation wetland shows no obvious spatial transfer. From 2020, proportion showed stable increase, with blue getting larger 10.8%. The indicators Number Patches (NP), Patch Density (PD), Largest Index (LPI), Contagion, Landscape Shape (LSI) decreased, suggesting better environment since establishment 2017. Based author makes following conclusion: construction results well-organized environment. provides reference building monitoring other regions.
