杭州分区县市空间辐射范围变化研究

Study On Space Radiation Range Change Of Districts,Counties And Cities Of Hangzhou

本文从经济发展、社会进步、生活改善、环境外联四大方面构建辐射力评价指标体系,运用主成分分析法计算了2000、2005、2010年和2014年杭州各区县市辐射力;其次,用加权Voronoi方法分析了各区县市空间辐射范围及其动态变化。结果显示:区县市空间辐射范围与行政范围之比为中心城区>远郊区>近郊区;中心城区空间辐射范围逐渐减小,对杭州市的辐射带动作用提高。近郊区的空间辐射范围增长明显,与中心城区竞争能力逐渐增强。远郊区的空间辐射范围未有较大改变,即为中心城区>近郊区>远郊区。区域开始协调发展,市域一体化发展特征已初步显现。

Based on four perspectives, Economic Development, Social Progress, Life Improvements and External Environment Relations, firstly, this paper established an Radiant Ability Evaluation Index System to calculate the Radiant Ability of districts, counties, and cities of Hangzhou by principal component analysis method respectively in 2000, 2005, 2010 and 2014.Secondly, this paper used Weighted Voronoi Method to analyze space radiation range of districts, counties and cities and theirs dynamic changes. The result show that：The ratio between space radiation range and administrative scope of districts, counties and cities is City Center Outer Suburbs Inner Suburbs;City center＇s space radiation range decreases, the radiant driving of the central city on Hangzhou increases. Inner suburbs＇ space radiation range increased significantly, and their competitiveness with City Center increased gradually. Outer Suburbs＇ space radiation range didn＇t have much change,which is The City Center Inner Suburbs Outer Suburbs. Region develops coordinately, the feature of urban region intergration development has been initially apparent.
