Tourism geography is a discipline that studies the spatial differentiation patterns, temporal development processes, and regional characteristics of tourism phenomena, tourism elements, and comprehensive tourism geographic systems. In the new development stage, grounding itself in China's context, addressing theoretical, practical, and methodological issues in China's tourism development practices, and providing Chinese paradigms and solutions for knowledge production are not only the mission of the Chinese tourism geography discipline but also key to enhancing its own disciplinary vitality. The disciplinary vitality of Chinese tourism geography is rooted in the scale, uniqueness, and complexity of China's tourism development practices, and is manifested in the process where tourism, as an "emerging developmental element and driving force", actively responds to national strategies and socioeconomic development needs. This study systematically reviewed the development processes and trends of knowledge production in tourism geography from the perspectives of disciplinary systems, academic systems, and discourse systems. The findings indicate that: 1) Multiple environmental factors, including institutional, socioeconomic, cultural, and disciplinary development contexts, collectively shaped the substantive content, presentation methods, and the theoretical and methodological consciousness of knowledge producers in tourism geography in China. 2) The construction of an autonomous knowledge system in Chinese tourism geography faces both internal and external challenges. External challenges are reflected in the mismatch between the construction of an international discourse system and China's international status, the disparity between developmental advantages and thematic advantages, and practices of academic hegemony. Internal challenges include the marginalization of tourism geography within the disciplinary system, fragmentation of research outputs, and the lag of theory behind practice. 3) Examining tourism development practices of Chinese-style modernization with a problem-oriented disciplinary awareness, defining the essential orientation of knowledge production in Chinese tourism geography with an academic innovation consciousness, and strengthening the autonomous narrative system of Chinese tourism geography with a discourse dialogue awareness are beneficial directions for overcoming the autonomy challenges. Accelerating the construction of an autonomous knowledge system in Chinese tourism geography is fundamental for enhancing the disciplinary vitality of tourism geography.

Urban heat island (UHI) effect is an important factor affecting the spatiotemporal variations of energy consumption for building cooling and heating in urban areas. Understanding the impact of UHI effect on building energy consumption is crucial for urban energy conservation, carbon emission reduction, and high-quality development. This article reviewed the relevant literature on the impacts of UHI effect on building cooling and heating energy consumption. It described the basic framework for the assessment of UHI effect on building energy consumption, summarized problems with the current research, and suggested potential future research directions. The review of the research results and main findings both in China and internationally show that: 1) Generally, UHI effect increases building cooling energy consumption and reduces heating energy consumption in urban areas. Magnitude of the increase in cooling energy consumption and the decrease in heating energy consumption varies in different regions depending on their climate zones and urbanization stages. 2) There are significant spatial differences in the impacts of UHI effect on building cooling/heating energy consumption, with the strongest impacts in the central urban areas and the weakest in the suburban areas. 3) During extreme weather and climate events (for example, heat waves), the synergistic effect of the UHI and extreme events affects the occurrence time and level of peak energy consumption in urban buildings. There are still uncertainties in the study of the impacts of UHI effect on building cooling and heating energy consumption, as well as limitations in the studies of the effects of extreme weather and climate events, large-scale high spatiotemporal resolution assessment, and mechanisms of UHI effect on urban building energy consumption. Further investigations are needed in areas such as applying high spatiotemporal resolution data, innovating research methods, and incorporating extreme weather and climate impacts.
