In addition, relationship between VICO strong positive correlation. distribution more consistent with GVI. affected GVI, plant richness, scale, diversity. Moreover, increase trend instead gradually decreased. contribution this not only accurately diagnosing problems shedding light on VICO, but also providing theoretical support for planning management, especially healthy design.
