滨海新区规划对区域生态网络结构的影响分析

以滨海新区2008年卫星影像、《滨海新区城市总体规划（2005-2020）》和《滨海新区城市空间发展战略研究（2005-2050）》为基础,在GIS技术下运用景观格局分析、网络结构分析及斑块间的相互作用力分析法研究了滨海新区规划对区域生态网络结构的影响。结果表明：滨海新区2008年生态网络景观破碎化严重且连通性差;《总体规划》侧重于斑块间的廊道连接,但大尺度斑块比例小;《战略研究》侧重于大尺度斑块的构建,但连通性较差;根据景观生态学原理,提出了滨海新区的生态网络结构改进建议。

Impact of Planning to Regional Ecological Network in Binhai New Area

Based on a land use map created from a landsat-TM satellite from the year 2008,two maps of planned land use for ecology of the general and strategic plans,the present situation and the effects of the two plans on the ecological network structure were researched with the methods of landscape spatial pattern analysis,of network structure analysis and quantitatively analysis on the interaction between the different patches on a GIS platform in Binhai New Area.The results showed that the ecological network had more fragmentations and poor connectivity in 2008,and the ecological network in the general plan focused on connecting corridor between the patches but the small proportion of large-scale patches,while the ecological network in the strategic plan focused on building large-scale patches but poor connectivity.Finally the improvement on the structure of the ecological network was proposed for the conservation of biological diversity.
