- 摘要:
- 城市土地低碳集约利用不仅符合低碳经济发展要求，更对城市和城市土地的可持续发展具有重要意义。为探究城市土地低碳集约利用的特点和评价方法，采用文献法、模型法和层次分析法，建立基于DSR模型的城市土地低碳集约利用评价体系，并以武汉市为实证研究区域验证其合理性。研究结果表明：2000—2010年武汉市土地低碳集约利用水平总体呈上升趋势，得益于武汉市政府采取了正确且有力的响应措施；武汉市DSR系统协调度与土地低碳集约利用水平呈现正相关关系；存在DSR系统驱动力相对不足以及响应的大幅提高制约土地低碳集约利用水平的问题，需合理改善和投入响应系统和驱动力系统的相关指标。研究结论：DSR模型能够成功运用于城市土地低碳集约利用评价，为城市土地低碳集约利用评价提供了概念模型，避免了指标归属模糊问题，并能够有效分析政策的实施效果。
- Abstract:
- The low-carbon and intensive urban land use is not only to meet the requirement of low-carbon economy development idea, but also is of great significance for the sustainable development of cities and urban land. To explore the characteristics and evaluation methods of low-carbon and intensive urban land use, we used the DSR model, ANP and literature method to establish an evaluation model for the low-carbon and intensive urban land use based on the DSR, and selected Wuhan City as empirical research area to validate the model rationality. The empirical study result show that the development level of low-carbon and intensive system in Wuhan based on DSR model was increasing from 2000 to 2010, and all above was thanks to the correct and effective response measures which Wuhan municipal government had taken,and there is a positive correlation between the coordination degree of DSR and the level of low-carbon and intensive urban land use. However, such problems as the driving-force is relatively inadequate and large-increasing in the response, which restricts the improving of low-carbon and intensive system level of Wuhan, it still need focus on the reasonable improvement and inputs on the indicators of the response system and the driving force system. The conclusion is that the DSR model can be successfully applied to the evaluation of the low-carbon and intensive urban land use. It provides the conceptual model for the low-carbon and intensive urban land use and an effective solution to the problem of fuzzy index attribution. Further more, it is able to effectively analyze the implementation effect of the policy.
