摘要:

乌鲁木齐市是坐落在绿洲上的城市,城市的生态环境较为脆弱。通过对城市土地利用/覆被变化及土地生态安全进行评价,揭示乌鲁木齐市1990—2017年间土地利用/覆被变化的规律、生态安全变化趋势。借助ERDAS和ArcGIS软件对乌鲁木齐市4期遥感图像进行解译分析,利用物元模型对乌鲁木齐市的土地生态安全现状进行评价。结果表明:1990—2017年乌鲁木齐市土地利用/覆被变化是以耕地、林地以及草地的转出和建设用地、未利用地的转入为主;各时段总体的土地利用/覆被变化呈现良好的发展态势且正处在发展期;乌鲁木齐市土地生态安全程度由不安全增长较安全水平。通过分析乌鲁木齐市土地利用/覆被变化情况及生态安全进行评价,为未来解决城市发展过程中所带来的诸多土地生态环境问题具有重要意义。

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
