Low-carbon landscape renewal strategies for tourist traditional village based on net carbon emission estimation: a case study of Leju village in Kunming

To study the net carbon emission estimation of traditional villages and the strategies for low-carbon rural landscape renewal, aiming to provide theoretical basis and reference ideas for the low-carbon landscape renewal and sustainable development of traditional villages.

Taking Leju village in Kunming City, Yunnan Province as the case study area, methods such as questionnaire survey, in-depth interview, mathematical analysis and GIS spatial analysis were used to statistically analyze the net carbon emissions of Leju village in 2022.

1) The net carbon emission estimation of traditional villages can be modeled from the perspectives of carbon sources and carbon sinks. The carbon source estimation index system of traditional villages includes six parts: tourism transportation, catering and accommodation, residents’ energy consumption, operation and management, solid waste and agricultural cultivation. The carbon sink structure system of traditional villages includes the ecosystem composed of ecological vegetation, agricultural crops, wetlands in water areas and various biological habitats. 2) In 2022, the carbon source emissions were higher than the carbon sink absorption in Leju village. Among them, catering and accommodation, residents’ energy consumption and solid waste were the main carbon sources, while agricultural crops and ecological vegetation were the main carbon sinks. The development of rural tourism had a certain impact on the local ecological environment. 3) Aiming to create an environmentally friendly low-carbon rural landscape, this paper proposes design strategies for "carbon source reduction-carbon sink increase" and low-carbon rural landscape renewal in traditional villages by establishing low-carbon type settlement space, creating ecological type natural landscape, promoting scientific and intelligent behavioral patterns.

Based on the estimation of net carbon emissions and combined with the cultural characteristics of the traditional villages, this paper proposes strategies for low-carbon rural landscape renewal, hoping to provide theoretical basis and reference ideas for the optimization of low-carbon landscapes in traditional villages and also provide a scientific and reasonable realization path for low-carbon tourism development.
