Abstract:
The Voronoi coefficient of variation and standard deviational ellipse methods were employed to study the characteristics and the change trend of spatial distribution of the beautiful countryside based on the beautiful countryside data from 2013 to 2017 in Henan province. The results show that:While the number of beautiful countryside in Henan has increased dramatically, the number is becoming more and more balanced in city scale;The spatial distribution patterns in the provincial and regional scales were changing from random distribution to cluster distribution,but the intensity of the changes in different regions is atypism, and the differ among different regions in spatial distribution patterns gradually decreases;The spatial distribution gravity of the beautiful countryside in Henan province moves northward in the mass and the moving speed and direction are different among different cross section in time;The distribution space is shrinking grandually;the direction characteristicis becoming weaker.In addition, the axis of spatial distribution is approaching to the due south-north direction.
