鄂尔多斯市康巴什新区城市绿地景观现状分析

Analysis of landscape pattern on the urban green space in Kangbashi New Area of Ordos city

利用2009年QuickBird遥感影像数据,通过对各种绿地面积及景观特征的研究,对鄂尔多斯市康巴什新区绿地景观现状进行分析。结果表明,鄂尔多斯市康巴什新区绿地面积为10.18 km2,城市绿地率29.34%。人均公园绿地面积很高,但整体绿化率距其规划目标还有一定的差距。绿地景观类型较齐全,且分布较均匀。公园绿地和道路绿地分别为研究区城市绿地景观的基底和廊道。居住绿地的破碎化程度较高,防护绿地边缘割裂的程度较高。城市绿地景观的Shannon多样性指数、Shannon均匀度指数和分离度指数分别为1.73、0.75和5.43。在此基础上,对城市今后发展提出相关建议。

In this paper, the current pattern of urban green space in Kangbashi of Ordos city was studied through the analysis of the feature of area and landscape of a variety of green space based on the QuickBird re- mote sensing data in 2009. The result showed that the green space area was of 10.18 km2, and city green rate reached to 29.34% in Kang Bashi New Area of Ordos city. The park green space area per capita was large, but the overall green space rate was lower than its goal of planning. Landscape type was relatively complete and the dis- tribution was uniform. The park green space and the path green space were corresponding to the matrix and corri- dor of urban green space in the studied area. The residential green space had high degree of fragmentation, while the protective green space had high degree of edge separation. The shannon diversity index, the Shannon evenness index and the separation index of urban green space landscape were 1.73, 0.75 and 5.43, respectively. On the basis of this, the related proposals for the city future development were advanced.
