Ecological Vulnerability of Tourism Scenic Spots: Based on Remote Sensing Ecological Index

Abstract

The assessment of ecological vulnerability plays an important role in the protection and management of scenic tourism sites. In this study, using remote sensing image data in the same month of 2000 and 2017, ecological vulnerability in the Tianchi Scenic Area (TSA) was analyzed by calculating the remote sensing ecological index (RSEI), and the influencing factors of ecological vulnerability were detected using the geographical detector model. From 2000 to 2017, the values of wetness, dryness, and temperature in the study area increased, and the value of greenness and RSEI decreased. Spatial correlations of the RSEI were significant, showing strong spatial agglomeration and alternating cold spots-hot spots-cold spots-hot spots from north to south. The impact factors of land use type, temperature, and precipitation showed greater contribution to ecological vulnerability. In addition, the local government implemented policies such as prohibition of mining, grazing prohibition, and landscape protection, which decreased ecological vulnerability in the study area. This study provides a reference for the formulation of ecological vulnerability protection measures in the TSA and theoretical basis for defining the monitoring indicators for heritage sites around the world.

A Long-Term Ecological Vulnerability Analysis of the Tibetan Region of Natural Conditions and Ecological Protection Programs

“…Studies in Europe and coastal areas have mainly focused on the sensitivity of the ecosystem and its response to climate change and pattern change over time [25][26][27][28][29][30], which measure ecosystem tolerance and vegetation response predictions to climate anomalies. In mainland areas, research on ecological vulnerability is more concentrated on land use patterns [31][32][33], desertification soil problems [24,[34][35][36], and human disturbances [37][38][39][40][41]. Typically, vulnerable zones with different topological characteristics are studied [38][39][40] to determine the determinants of vulnerability.…”

Typically, vulnerable zones with different topological characteristics are studied [38][39][40] to determine the determinants of vulnerability. Appropriate ecological management policy should consider both environmental and socio-economic factors, which are built on an objective and integrated evaluation system.…”

“…Mainly, current ecological vulnerability studies in Tibet are limited to specific prefectures or certain aspects of driving factors such as the Sichuan-Tibet railway [37]. These studies have inaccurate analytical units, a small range of study periods, influences from single-type indicators, and inadequate evidence on determinant analysis [40][41][42][43][44][45]. Though numerous studies have investigated ecological health and ecosecurity and assessed the ecological risk of the Tibetan Plateau, more research is still needed on an ecological vulnerability analysis with an ecological protection project policy in the Tibetan Plateau [1,15,31,35,45,49].…”

Ecotourism risk assessment in Yaoluoping Nature Reserve, Anhui, China based on GIS

“…This study of ecotourism risk assessment mainly focuses on nature reserve, scenic spot, forest park, wetland park, and so on. In terms of evaluation scale, ecotourism risk evaluation has gradually shifted from provincial and municipal units to county, village and scenic spots (Yang et al 2018;Lebrão et al 2021;Shi et al 2021).…”

Spatio-Temporal Evolution Measurement and Obstacle Factors of the Vulnerability of Water-Energy-Food-Ecology Nexus in the Yangtze River Economic Belt

“…For example, selecting indexes such as water consumption per 10,000-yuan GDP and per capita domestic water consumption to reflect the impact of economic development and human activities on the vulnerability of water resources. However, the research on the vulnerability of the water-energy-foodecology nexus is still mainly focused on individual subsystems, especially the water subsystem [30][31] and ecology subsystem [32][33][34][35], only a few scholars have studied the vulnerability of the water-energy-food nexus [36]. Based on the definition of vulnerability [26], this research believes that the vulnerability of the waterenergy-food-ecology nexus is caused by the unbalanced development of the internal system and the disturbance of the external environment, such as human activities and natural conditions.…”
