Abstract
Longji Terrace, one of the three ancient terraces in China, is a comprehensive tourist scenic spot with agricultural terraces as the main body and integrating natural landscape, cultural landscape and ethnic customs. In this paper, taking Longji Terrace in Guilin as the research object, using geographic information technology to study its ecosystem structure from the aspects of space, components, etc., to explore the material and energy flow patterns of the ecosystem, and to analyze the service functions of the ecosystem, so as to provide basic information for the healthy and sustainable development of the local ecological environment.
Highlights
With the increasing global change and human disturbance, the evolution and regulation mechanism of wetland ecosystem has become a hot spot in the world
Domestic researches on Longji terraced fields are mostly focused on ethnic tourism and farming culture, etc. [4][5], while the research on local ecosystem is less, while the stability of ecosystem is the basis for maintaining the development of local tourism economy and the continuation of ethnic culture, and its importance is selfevident
Clean spring water in Longji terrace ecosystem can be directly introduced by local villagers and used in daily life and production, and the generated domestic sewage, faeces and garbage can be transported to terraces with natural or artificial drainage systems and received by terraces along the mountain, increasing the soil fertility of paddy fields [11]
Summary
