摘要: 应用面向对象的影像分析技术(eCognition)和乌鲁木齐市QuickBird数据,从绿地景观着手,运用景观生态学的原理和方法,对比分析乌鲁木齐市新城区和老城区的绿地景观格局,结果表明:新城区绿地景观多样性较高,分布较均匀,绿地缀块破碎度小,绿地廊道密度和分维数都较低;老城区绿地景观优势度大,分布分散,较破碎,廊道密度和分维数都较高.还对乌鲁木齐市绿地景观生态建设进行了探讨.Abstract: A comparative study was done on the landscape patterns of green-space in both of the old and new urban areas of Urumqi city in the light of the theory and research methodology by means of eCognition techniques and QuickBird data of the city. It was showed by the results that the landscape of the green-space in the new urban area of Urumqi was with higher diversity, evener distribution, less fragmentation, lower corridor density and lower fractional dimension. Whereas there were higher dominance, more dispersive distribution, much more fragmentation, higher corridor density and higher fractional dimension features shown by the green-space landscape in the old urban area. Consequently, a discussion was made toward the ecological construction of green-space landscape in Urumqi.
