Abstract:

Urmqi,as a city located on oases,its ecological environment is little bit weak.Through assessment of city earth usage/changes of earth covering and earth ecology safety,reveals the trend of earth usage/changes rule of earth covering and earth ecology safety during 1990-2017 in Urmqi city.Assisted with ERDAS and ArcGIS software,explains and analyzes 4 sessions remote-sensing map of Urmqi city and evaluates Urmqi city's earth ecology safety current situation by matter-element model.The result shows that in 1990-2017,earth usage/changes of earth covering was mainly represented by leasing of cultivated land,forest land and grass land,and the new gained of construction land,not used land.Different periods' development situations of earth usage/changes of earth covering are good and developing.The earth ecology safety level of Urmqi city has reached safe level from unsafe level.By analyzing Urmqi city's usage/changes of earth covering and evaluating its ecology safety,it has profound significance for many earth ecology environment problems occur in city development in the future.

Key words: land use/cover change, ecological security, entropy weight method, matter-element model, Urumqi
