Fig 2.
Spatial distributions of landscape metrics in green spaces of buffer areas in industrial parks of North China.
Abbreviations: Area_Green Space, green space area; Surface height_Green Space, height of surface features in green space; DEM_Green space, elevation of area in green space; Surface height_Buffer, height of surface features in buffer areas for an industrial park; DEM_Buffer, elevation of buffer area in an industrial park. Mapping data were sourced from NASA Earth Observatory (public domain) (http://earthobservatory.nasa.gov/) which comply with the CC BY 4.0 license.
Fig 3.
Spatial distributions of green view index (GVI) (A) and Simpson diversity index (Simpson index) (B) in industrial parks of North China.

Fig 4.
Spatiotemporal distributions of workers’ facial expressions scores in industrial parks at regions of North China across four seasons.
(A-1) to (A-4), happy score distributions; (B-1) to (B-4), sad score distributions; (C-1) to (C-4), neutral score distributions; (D-1) to (D-4), PRI score distributions. Mapping data were sourced from NASA Earth Observatory (public domain) (http://earthobservatory.nasa.gov/) which comply with the CC BY 4.0 license.
Fig 5.
Facial expression scores for workers among industrial parks for happy (A), sad (B), neutral (C), and PRI (D) scores.
Different lower-case letters indicate significant difference using Duncan test at 0.05 level. Data were transformed by ranking in difference detection, but they are transformed back to raw values and used for calculating averages for industrial parks.

Variations of satisfactory salary (A) and recovery of expected salary (B) among industrial parks.
Fig 7.
Spatial distributions of recruitment wage (RW) (A), satisfactory salary (B), and recovery of expected salary (RES) (C) in industrial parks located at regions of North China.
Mapping data were sourced from NASA Earth Observatory (public domain) (http://earthobservatory.nasa.gov/) which comply with the CC BY 4.0 license.
