Table 1

Global ST-Moran index range and corresponding meaning.

Variable name	Value range	Interval	Meaning of state
	(−1, 1)	(0, 1)	The segments with similar attributes are clustered in spatial and temporal distribution. The larger the value, the more obvious the aggregation
		0	The segments with similar attributes are random in time and space distribution
		(−1, 0)	The segments with similar attributes are discrete in spatial and temporal distribution. The smaller the value, the more obvious the dispersion
