低碳经济理念下绿地景观格局优化方法研究

Green Space Landscape Pattern Optimization Method under Low Carbon Economy Concept

自然绿地景观格局的优化主要分为两部分工作,一是对原有的绿地景观格局进行定量分析,得出绿地景观布局存在的不合理之处。二是针对上述定量分析结果,建立绿地景观格局优化模型,首先对建立该优化模型的四项关键技术进行分析,然后简要介绍了格局优化流程,最后实现绿地景观格局优化,弥补原有自然绿地景观格局存在的不足。与原有绿地景观相比,优化后的自然绿地景观格局的适宜性和聚集度都有明显提高,分别为15. 40%和8. 40%,二氧化碳的吸收量增加了23. 5%,基本达到该研究的目的,证明了该格局优化方法的有效性。

The optimization of the landscape pattern of natural green space is mainly divided into two parts.The first part is to conduct quantitative analysis on the original landscape pattern of green space to found the unreasonable place of the layout of the green landscape.The second part is to construct optimization model of green landscape pattern based on the quantitative analysis.Four key technologies for establishing the optimized model are analyzed,and then the pattern optimization process is briefly introduced.The optimization of green landscape pattern is realized to make up for the shortcomings of the original natural green landscape pattern.The results showed that compared with the original green landscape the suitability and aggregation of the optimized landscape pattern of natural green space were improved,15.40%and8.40%respectively.The absorption of carbon dioxide increased by23.5%,which basically reached the purpose of this study,which proved the effectiveness of the pattern optimization method.
