Using Remote Sensing to Monitor the Water Change of Xiong’an New Area

Water is an indispensable part of urban development and ecological environment protection. Xiong'an New Area is a state-level new areas established to adjust and optimize the urban layout and spatial structure of Beijing-Tianjin-Hebei. Exploring the water changes of the Xiong'an New Area is critical to local development. In this paper, the Spectrum Matching based on Discrete Particle Swarm Optimization (SMDPSO) method—an effective approach for complex water extraction was used to extract the waters of spring in 1984, 1989, 1993, 2000, 2008, 2014 and 2018 and combined with the water extract results of 28 years to analyze the water degraded and restored areas of the Xiong'an New Area. The largest water area (280 km
²
) in Xiong'an New Area appeared in 1989. Water degraded areas is distributed in strong change zone and strong change zone and water restored areas is distributed in weak change zone and micro-change zone.
