Evaluation of Land Use and Land Cover Change and Spatial Ecological Impacts Using GIS: A Case Study of Urumqi's Primary Urban Area

In this study, GIS technology was used to take the main urban area of Urumqi as an example to conduct an in-depth study of the land use cover change and its spatial ecological effects in the past 30 years. It is found that the rapid urbanization process has led to the gradual reduction of arable land and vacant land, while the area of land designated for construction has witnessed a notable upward trajectory. The alteration in land use has had a profound effect on the ecological environment, changed the original ecological pattern, and has had a non-negligible impact on air quality, soil fertility and biodiversity. Therefore, advocating reasonable land use and proposing and implementing sustainable urban development strategies are very important for the future development of the main urban area of Urumqi.
