Study on the spatiotemporal response of landscape quality and tourist trajectories in alpine grassland of Zoige County
The coordinated development of plateau tourism and ecological environment is an important content in balancing human-land relations.Under the influence of climate change and human behavior,grasslands in northwest Sichuan have experienced varying degrees of desertification,which severely restricts the sustainable development of local tourism economy.This paper takes Zoige County as the study area,uses remote sensing data and the alpine grassland desertification index(AGDI),to measure the grassland desertification situation from 2015 to 2021,analyzes the characteristics and patterns of tourists'trajectory from 2015 to 2021 based on trajectory big data.Then the coupling coordination model was used to explore the spatiotemporal response between grassland landscape quality and tourists'trajectories,and explores the temporal and spatial responses between the grassland landscape quality and tourists'trajectories with the help of the coupled coordination model.The results show that:(1)From 2015 to 2021,the area of sandy grassland in Zoige decreased by 14.91%overall,while the landscape quality of grassland increased by 2.87%.The severe and moderate sandy areas in the middle of Zoige were gradually reduced.(2)From 2015 to 2021,the number of tourism trajectories in Zoige showed a fluctuating upward trend.The research discovered three types of self-driving modes:G213 National Highway self-driving pattern,the Yellow River grassland self-driving pattern,the S217 Provincial Highway self-driving pattern;three types of hiking modes:the Namo Canyon hiking pattern,the S217 Provincial Highway hiking pattern,and the Huahu Lake Scenic Area hiking pattern.All six types of tourists'trajectory modes were distributed along scenic areas and transportation arteries(national and provincial roads).(3)From 2015 to 2021,the coupling degree between the quality of grassland landscape and tourist trajectory in Zoige increased from 0.22 to 0.71,and the coupling coordination degree increased from 0.3 to 0.74,developing from intermediate dissonance to intermediate coordination.This study attempts to analyze the spatiotemporal response between tourists'spatial behavior and ecological environment with tourist trajectory data,providing a new idea for improving the research accuracy of tourism activities'environmental impact,and providing theoretical support for plateau grassland resource protection and tourism utilization management on the plateau.
