His research programme is dedicated to geographic information science, remote sensing, and territorial spatial planning, with particular emphasis on the development of GIS technologies for urban and regional analysis, land-use change monitoring, and the digitalisation of territorial spatial governance. Through sustained leadership of national major research programmes and the development of virtual simulation experimental teaching platforms, he has produced transformative contributions to the education and application of geospatial science in China. Author of numerous peer-reviewed publications and monographs, he has been instrumental in advancing the integration of GIS, remote sensing, and spatial analysis into national territorial spatial planning and sustainable development strategies. Through sustained leadership of national teaching innovation programmes and international scientific collaboration, Professor Li has established a legacy that bridges fundamental geospatial science with the practical imperatives of smart territorial governance, ecological civilisation, and sustainable regional development across the Eurasian region.
