基于用地区位的城市生态新区静态交通需求预测模型研究

在城市生态新区规划建设过程中,进行动态交通规划的同时,需要在把握未来趋势的基础上,对静态交通需求进行正确的预测。结合城市生态新区静态交通需求影响因素分析,对比研究典型的传统静态交通需求预测模型,引入静态交通区位理论,从地理、社会、环境、交通及公交等5个方面量化生态新区的静态交通区位优势,建立了基于用地区位的城市生态新区静态交通需求预测模型,以汕头市南滨片区为例证明了该模型的可行性。

生态城市新区可持续发展的法律问题研究——以陕西省西咸新区、浐灞生态区为例

在生态城市新区的建设发展中,协调经济与环境等关系,实现可持续发展是面临的首要问题,因此,建立完善高效的法律机制不可或缺。本文基于对陕西省西咸新区、浐灞生态区特征及问题的分析,提出了立法理念和实施重点,认为这种法律机制的基本理念应秉持社会福利最大化,协调区域多元利益发展主体的权力分配关系,在保证社会公平的基础上促进经济社会与资源、生态环境等的协调可持续发展。

Quantitative Evaluation on Urban Ecosystem Carrying Capacity in Tianjin Binhai New Area

Based on the concept of ecosystem carrying capacity,the indicator system of quantitative assessment was set up,which consisted of support indicator system and pressure indicator system.And the factor analysis method was used to screen the indicator system.Different from the traditional indicator weight determination based on the absolute values of the coefficients of regression equation,the squares of factor loadings in the rotated component matrix were attempted to determine the weights of 40 assessment indicators.The result shows that ecological support system and pressure system in Binhai New Area are relatively balanced among six years,and the developing level of urban ecosystem is basically healthy on the whole.However,due to continuously increasing pressure of the resources consumption caused by the rapid growth of the second industry,which is the Leading Industry of Binhai New Area,the ecosystem carrying capacity reached the minimum in 2005.
