老工业城市绿地景观格局分析与优化——以长春市为例

研究以IKONOS为主要信息源，并利用GIS软件，建立长春市绿地地理信息系统，在景现生态学理论的基础下，利用各项景观指标全面分析，定量地研究长春市绿地系统。结果表明，长春市中心区公园绿地建设和保护比较完善，但附属绿地和道路绿地破碎化较严重；周边工业区的附属绿地和道路绿地分布均匀，但公园绿地面积较少；北部的绿地面积较少、破碎化较严重，各类绿地分布不均匀。为了长春市城市绿地格局更加合理，城市绿化效果更好，提出以下几点建议：解决破碎化问题，建立绿地廊道系统；针对工业城市的特点进行规划设计，规定绿化指标；政府参与支持和监督。图6，表1，参19。

Analysis and Optimization of Landscape Pattern of Green Land in Old Industrial Cities A Case Study of Changchun

Geographical Information System of Changchun City was established by the main information source of IKONOS and GIS software. On the basis of the theory of landscape ecology, green land system of Chaugchun City was quantitatively realized by the compre- hensive analysis of each landscape index. The results showed that, the construction and protection Of park green laud in the central area of Changchun City was perfect, but the fragmentation of affiliated green land and road green land was serious. On the other hand, the distribution of affiliated green land and road green land of peripheral industrial area was uniform, but the area of park green land was small. In the north, the area of green space was small, the fragmentation was more serious, and the distribution of various green land was non-uniform. A few suggestions were put forward in order to make more reasonable pattern of green land and better greening effect of Changchun City. The corridors green land system was established for the solving of the problem of fragmentation. Planning and design were carried out, and the green indexes were stipulated according to the characteristics of the industrial city. Supporting and supervision from the government were participated.
