The TCIs (tourism climate indices) are applications of the human comfort
in climate health tourism. TCIs aim to characterize the climate and
environmental status of tourist destinations and provide a comprehensive
measure of tourists’ climatic well-being. In this study, the Web of Science
and China National Knowledge Infrastructure (CNKI) databases were searched for
visualization analysis, explained the connotation of the TCIs and human comfort
index, summarized the historical evolution of TCIs and the human comfort index,
and discussed the existing problems and countermeasures of TCIs researches. In
order to provide theoretical support for the indepth research and sustainable
development of TCIs in the future. The results are as follows: (1) The English
studies were more concerned with tourism satisfaction and competitiveness,
whereas the Chinese studies were more concerned with human comfort, climate comfort,
and climate tourism. (2) Human comfort indices were primarily composed of
meteorological factors and clothing insulation, which aims to reflect the human
body's feeling of environmental comfort. The TCIs not only covers
meteorological factors and aesthetic factors, but also considers health factors
such as air quality and oxygen content, aiming to comprehensively evaluate the
suitability of tourism activities and the effect of climate health of
travelers.
