轨道交通TOD开发密度分区构建及容积率确定——以深圳市轨道交通3号线为例 总被引:1,自引:0,他引:1
为满足轨道交通站点周边土地开发的需要、形成TOD的发展格局,从站点类型和开发圈层两个层面构建站点周边土地开发的密度分区制度,制定一套适用于不同类别地区的开发强度标准,作为土地开发容积率的控制准则。依据车站功能定位将车站划分为综合站点和一般站点两种发展区域类型;利用非参数统计学的局部线性回归法对地价和地块距站点距离两个参量进行拟合,确定轨道交通影响半径,进而将站点周边划分为三个圈层,300m以内为高密度复合开发区,300~600m之间为中密度开发区,600~1000m之间为低密度开发区,开发强度随用地与车站距离的增加而递减,商业开发应尽量建于核心圈层。应用经济学原理分析土地开发强度与开发利润的关系,分析结果表明,存在使土地开发利润最大的最佳容积率;以政府利润最大化为优化目标,构建土地开发强度优化模型,并进行敏感性分析;利用深圳市轨道交通3号线沿线住宅售价和建造成本测算了各密度分区的最佳开发强度。 相似文献

依托GIS技术,本文提出了一种在开发区内进行工业用地更新方法。该方法由更新空间识别、更新方向判定两个步骤组成,以城市用地的空间布局优化为出发点,获取工业用地更新空间位置和判定更新方向。更新适应性评价是通过模型推演地块(企业)的更新适宜性,采用土地适宜性评价的方法,定量计算各个工业地块的调整潜力,明确需更新的地块;更新方向判定对于待更新地块宜居环境、公共服务水平进行定量分析,得出不同更新政策的工业用地调整方案。本研究所提出的方法对工业用地调整方向研究、工业用地调整政策制定、工业用地调整实施方案等更新问题提供参考依据,也可以为其他开发区的工业用地更新提供空间决策支持。 相似文献

取得土地使用权是房企开发项目的根本,现阶段大多数开发企业主要是通过拍卖的形式竞得土地使用权,在竞拍过程中开发企业举牌的依据来源于积极的市场预期、精准的项目定位、细致的成本分析和合理的财税测算,而拿地概念方案是上述要素的具体呈现与技术保障。文章立足于挖掘地块价值、追求地块溢价,就拿地概念方案的工作流程与设计要点进行简单论述。 相似文献

生态环境和城市房地产开发利用是一个整体,在城市房地产开发和再开发过程中,必须以生态环境的保护和合理利用为前提,采取一定措施,合理布局,使城市房地产开发和生态环境保护两者达到有机统一。一、合理利用土地,提高城市土地的生态经济效益由于城市土地的利用价值主要受所处的位置环境条件影响,土地的区位不同,地块的开发程序和基础设施不同、生态环境的质量不同,相应地块房地产项目的聚集效应和获得的收益也不同,从而影响土地利用价值,因此,合理利用城市土地,就是对城市土地的使用、收益和保护的综合考虑,包括控制城市用地规… 相似文献

This paper examines income‐related housing support in Britain and the Netherlands. It considers the main issues that are at stake in current policy discussions, compares the arguments that are put forward in the two countries and draw conclusions about the future of income‐related housing support. In both Britain and the Netherlands political discussions about the possible introduction of housing vouchers are observed. The most complicated issues are the poverty trap and unemployment trap, and housing consumption incentives. Moral hazard concerns can result in complicated anti‐fraud measures that may add to the burden of administering income‐related support. It is expected that the way in which income‐related housing support schemes in both countries are designed and administered may come under closer scrutiny. Politicians want these schemes to be in tune with the need for labour and housing market mobility, wage flexibility, and the need to bring the public budget under control. 相似文献

Although metro systems have been recognized as a sustainable transport mode, they are financially risky investment projects in light of the high capital and operating costs. This paper attempts to examine the socio-economic yardsticks commonly used for evaluating the readiness of cities in building metros, and to analyze how these socio-economic indicators changed before and after their construction. Specifically, the socio-economic indicators are population size and income level. Data of 60 metro lines in 21 cities on different continents were pooled for the analysis. The results suggest that the commonly-adopted population yardstick is still generally applicable but the income yardstick needs to be changed. After analyzing the population and income changes for the 10-year periods before and after the opening of the metro lines, it was found that the building of metros was usually preceded by a period of sustained high population and income growth. However, the rates of population and income growth would tend to decrease after the completion of the metros. 相似文献

切实满足用户需求是住宅产业化发展的根本。深入不同收入群体中,有针对性地探索住宅产业化背景下用户对住宅结构-功能的需求变化,则是优化住宅的功能资源配置以及最大化不同收入用户群体对住宅产品满意度的关键。采用 Kano模型与问卷对住宅产业化背景下用户需求进行识别与分类,依据需求满意度的相关指标,提出不同收入用户群体中需求变化的分析模型,结合调研数据分析得到不同收入群体对住宅产品需求的满意度变化结果。研究发现,无论住宅产业化背景下用户需求的 Kano 类别是否对收入变化敏感,需求的满意度总是对收入变化具有敏感性,并且满意度会随收入变化呈现出波动性增长的趋势。研究结果对于未来市场细分环境下住宅产品的研发以及推动我国住宅产业化的发展具有重要的借鉴意义。 相似文献

在常规的岩体统计均质区划分方法中,产状数据相似性判定结果通常会受到投影图子区划分方案的影响,并且不适用于小样本数据。为解决上述问题,引入二维K-S检验法进行产状数据相似性判定。首先介绍了K-S检验法的基本原理,继而根据二维K-S检验法提出了产状数据相似性判定的具体算法,并利用算例验证了算法对小样本产状数据的适用性。最后,针对北山坑探设施斜坡道进行了应用和验证。提出的算法不需要进行投影图子区划分,适用于小样本数据,为岩体统计均质区划分提供了一种新手段。 相似文献

Nonpoint source (NPS) water pollution is one of serious environmental issues, especially within an agricultural system. This study aims to propose a robust chance-constrained fuzzy possibilistic programming (RCFPP) model for water quality management within an agricultural system, where solutions for farming area, manure/fertilizer application amount, and livestock husbandry size under different scenarios are obtained and interpreted. Through improving upon the existing fuzzy possibilistic programming, fuzzy robust programming and chance-constrained programming approaches, the RCFPP can effectively reflect the complex system features under uncertainty, where implications of water quality/quantity restrictions for achieving regional economic development objectives are studied. By delimiting the uncertain decision space through dimensional enlargement of the original fuzzy constraints, the RCFPP enhances the robustness of the optimization processes and resulting solutions. The results of the case study indicate that useful information can be obtained through the proposed RCFPP model for providing feasible decision schemes for different agricultural activities under different scenarios (combinations of different p-necessity and pi levels). A p-necessity level represents the certainty or necessity degree of the imprecise objective function, while a pi level means the probabilities at which the constraints will be violated. A desire to acquire high agricultural income would decrease the certainty degree of the event that maximization of the objective be satisfied, and potentially violate water management standards; willingness to accept low agricultural income will run into the risk of potential system failure. The decision variables under combined p-necessity and pi levels were useful for the decision makers to justify and/or adjust the decision schemes for the agricultural activities through incorporation of their implicit knowledge. The results also suggest that this developed approach is applicable to many practical problems where fuzzy and probabilistic distribution information simultaneously exist. 相似文献
