Spatio-temporal Evolution of Interactive Coercing Relationship between Tourism Resource Development and Landscape Ecological Security:A Case Study of the Guizhou Section of Chishui River Basin
There is an obvious interactive relationship between tourism resource development and landscape ecological security,clarifying the specific mechanism of the two is of great significance to achieve a solid ecological security barrier and high-quality tourism development.By taking the Guizhou section of Chishui River Basin as an example,this paper firstly constructed two grid-scale models to analyze the intensity of tourism resource development and landscape ecological security,and then used a du-al index model to explore the spatio-temporal evolution rules of interactive coercing relationship between the two from 2010 to 2020.The results are shown as follows:① The development intensity of tourism resources in the study area shows a continuous increase.As areas with high-level development of tourism resources expand rapidly,the development pattern changes from"punctiform development"to"zonal development",gradually forming a spatial pattern with core scenic area as the growth pole and the northeast-southwest axis and northwest-southeast axis as the two axes.② The overall level of landscape ecological se-curity in the study area is high and stable,and areas with medium and high-level continue to increase,forming two landscape ec-ological security axes of northeast-southwest axis and northwest-southeast axis but with a fluctuating development trend.③The overall collaborative development of tourism resource development and landscape ecological security in the study area is im-proving,forming a positive collaborative areas with the northwest and southwest areas as the focuses and the dual-axis of land-scape ecology as the link.However,there are differences in the specific regional collaboration paths,among which the southwest and the concentrated contiguous areas with weak ecological backgrounds face greater pressure on ecological landscape protection before realizing positive synergy,while central areas on the dual-axis,where tourism resource development is at the primary and intermediate levels,are more likely to be affected by the rate of tourism resource development.
