基于RS和GIS的乌鲁木齐市城市绿地景观评价研究

利用QuickBird数据,采用eCognition面向对象技术,应用景观生态学原理和方法,对乌鲁木齐市城市绿地景观进行了系统评价研究.结果表明:乌鲁木齐市绿地景观分布不均匀,新市区最破碎,水磨沟区最完整,附属绿地、居住绿地较破碎;公共绿地、生产绿地、防护绿地较完整,空间分布格局趋向于随机分布;城市绿地景观形状简单,各区绿地廊道分布相差较大.研究结果对乌鲁木齐市城市绿地建设和生物多样性保护以及2013年创建国家级园林城市具有指导意义.

Evaluation on Greenland Landscape Based on RS and GIS in Urumqi

Based on QuickBird remote sensing image,with the application of eCognition object-oriented image classification technique and principles and methods of landscape ecology,urban the greenland landscape in Urumqi was evaluated.The results showed that urban greenland was fragmented and unevenness.Xinshi region was fragmentary while Shuimogou region was integral.Affiliated greenland and residential greenland was fragmentary,while public greenland,production greenland and shelter greenland integral.The urban greenland was nearly randomly distributed and the shape was simple.The corridor density was not even in every region.To construct urban greenland,conserve biodiversity,and build up Chinese Landscape Architecture City of national level in 2013,it was significantly necessary to evaluate the urban greenland landscape in Urumqi.
