摘要
高原旅游业与生态环境协调发展是平衡人地关系的重要内容。在气候变化和人类行为的影响下,川西北草地已经出现不同程度的沙化,严重制约当地旅游经济的可持续发展。本研究以若尔盖县为研究区域,运用遥感数据和高寒草地沙化指数(AGDI)测算了2015—2021年草地沙化情况,基于轨迹大数据分析2015—2021年游客轨迹特征及模式,借助耦合协调模型探究草地景观质量和游客轨迹间的时空响应。结果表明:(1)2015—2021年,若尔盖县沙化草地面积总体减少14.91%,草地景观质量上升2.87%;分布于若尔盖县中部的重度、中度沙化区域逐渐缩小。(2)2015—2021年,若尔盖县旅游轨迹数量呈波动上升趋势,研究挖掘到G213国道、黄河大草原、S217省道3类自驾模式和纳摩峡谷、S217省道、花湖风景区3类徒步模式,6类旅游轨迹模式均沿景区及交通干道(国道和省道)分布。(3)2015—2021年若尔盖县草地景观质量和游客轨迹耦合度从0.22升至0.71,耦合协调度从0.30升至0.74,由中级失调发展为中级协调。本研究尝试以游客轨迹数据分析游客空间行为与生态环境间的时空响应,为改善旅游活动环境影响研究精度提供了新思路,为高原草地资源保护和旅游利用管理提供理论支持。
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.
