Abstract: This study takes typical ecological cities as the research object, is supported by ecology and related disciplines, and focuses on geographic information system (GIS) technology, digital elevation model (DEM), land use maps and administrative division maps. Combined with the regional characteristics of the city, the ecological environment of the study area was systematically analysed. The analysis results show that the threshold of urban green coverage, the utilisation level of industrial solid waste, and the level of harmless treatment of urban solid waste are usually between 0.6 and 1, and the per capita community green space is usually between 0 and 0.4, which is worse than the standard threshold.

Keywords: GIS technology; environmental carrying capacity; ecological landscape; ecological construction model.
