摘要
由于建立在荒漠背景之上,绿洲城市生态环境比较脆弱,城市自然景观在城市生态建设中的作用尤为重要,本文以乌鲁木齐为研究对象,借用景观生态学的方法,在ERDASINMAGINE和ARCVIEW软件的支持下进行景观要素的划分,从绿地斑块组成和格局以及城市自然廊道系统方面分析乌鲁木齐市的景观空间格局的特点及生态环境现状,提出:绿洲城市生态建设中应注重绿地系统内部结构和空间布局的调整,扩大绿地景观面积,适当提高林地比重,增加绿地组成多样性;改建河流廊道,充分发挥河流廊道的生态效益。
Oasis cities have more fragile ecological environment because they are founded in the background of desert. The spatial pattern of the natural landscape is the most important factor in the ecology of oasis cities. With the help of ERDAS INMAGINE and ARCVIEW, this research analyzed the features of Urumqi＇s spatial patterns and the present status of the ecological environment based on the landscape ecology method. Then some improvement methods were put forward. Pay more attention to the adjustment of inner structure and spatial pattern of greenland system in Urumqi; Expend its greenland and improve the ratio of arbor and brush in the urban greenland system; Use local plants to increase the diversity of Urumqi＇s greenland components; Rebuild the river corridor to enhance its ecological effects.
