基于集约和节约利用的土地储备研究——以重庆市都市圈为例 总被引:2,自引:0,他引:2
土地储备有利于促进但不必然带来城镇建设用地的集约和节约利用。以重庆市都市圈为例,文章探讨了在土地集约和节约利用条件下,一定时期土地储备控制规模的(即规划储备量)预测方法。文章分析了土地储备控制规模确立的思路与技术流程,包括预测城镇建设用地总需求、总供给;评价或评估现状土地集约利用水平与潜力;在此基础上预测土地储备控制规模(含土地储备增量规模和存量规模)。据此方法和原理预测出重庆市都市圈未来15年的土地储备控制规模。基于集约利用的土地储备控制规模的确定是土地储备规划和土地储备年度计划制定的基础。 相似文献

政策与土地是开发区的相互互动的基本资源。开发区土地资源集约利用水平与评价体系有助于鉴别开发区土地利用效率效益,从而推动开发区的政策导向,促进我国开发区可持续发展。本文从提高开发区土地集约利用水平和产业集聚发展程度的角度出发,提出了开发区土地集约利用的系列策略,在此基础上,分别从开发区土地开发进度、投入产出效果、工业用地效益三个方面科学构建了开发区土地集约利用评价指标体系,并评价指标体系的实施应用及意义作了充分的论述,对做出了积极的探索。 相似文献

以乐陵市中心城区建设用地为研究对象,根据功能区划定方法、原则,划分为159个功能区,选取评价指标因子,确定指标权重值和理想值,构建指标评价体系,运用综合评价法计算各功能区土地集约度,以此为基础分析功能区现状主导用途与规划用途差异性,测算现实条件下中心城区用地规模潜力。结果表明:(1)建设用地集约利用度以低度利用为主,集约利用、中度利用、低度利用区面积分别339.10 hm~2、312.63hm~2、640.75 hm~2;(2)建设用地具备较高的挖潜潜力,高潜力区、中潜力区、低潜力区面积分别为90.56hm~2、290.58hm~2、386.33 hm~2,主要集中在居住和工业功能区。 相似文献

本文对我国城市居住与工业用地比例进行了统计分析。近20年来我国城市居住与工业用地的面积比呈"倒V"型,曲线转折点为2001年。用地出让制度改革、政绩考核及现有的税收体制导致地方政府2002年之后的供地偏好转变,产生了低价、超量供应工业用地与高价、缩量供应居住用地的供地倾向,致使我国城市工业与居住用地供应出现结构性失衡。在对近10年全国居住用地比例、商品住宅供求关系、商品住宅平均价格回归分析和相关研究的基础上,笔者从实证角度验证了居住用地比例下降(即居住用地供应不足)在房价过快上涨过程中所起到的基础性作用。最后,论文针对城市建设用地的结构优化及居住用地供应保障问题提出了相关建议。 相似文献

旧版《城市用地分类与规划建设用地标准》中工业用地标准与其在利用过程中出现的问题具有相关性,原有规划建设用地标准无法实施有效控制。随着城市工业的发展及工业用地管理的日益严格,工业用地标准应做相应调整,如按照工业用地对居住和公共环境的干扰程度来进行分类,考虑各地区、各类型城市的不同特点和工业化发展阶段提出城市工业用地指导型比例,修正人均工业建设用地指标等。 相似文献

本文基于南宁市移动手机信令数据识别的居民居住地、工作地数据,首先分析了南宁市职住平衡特征及其与土地混合使用间的关系,研究发现南宁在控制性详细规划单元尺度存在职住空间不平衡现象,职住平衡指标与土地混合使用指标间具有一定的相关性。接着采用逐步多元回归方法检验了职住平衡、土地混合使用对通勤距离的交互影响。研究发现,较好的职住平衡可以降低通勤距离,居住在就业较密集的单元,或工作在居住较密集的单元,通勤出行相对较短。较好的土地混合使用水平可以缩短通勤距离,居住在居住与非居住用地混合度较好、公共服务设施混合度较好的单元,居住者通勤距离较短,工作在4类主要用地混合度较好、工业用地占比合理、医疗及教育设施密度较好的单元,工作者通勤距离较短。研究为南宁制定优化土地使用规划政策,改善居民职住平衡水平及通勤模式提供了依据。 相似文献

Modeling the effects of past and current land use composition and climatic patterns on surface water quality provides valuable information for environmental and land planning. This study predicts the future impacts of urban land use and climate changes on surface water quality within Des Plaines River watershed, Illinois, between 2010 and 2030. Land Change Modeler (LCM) was used to characterize three future land use/planning scenarios. Each scenario encourages low density residential growth, normal urban growth, and commercial growth, respectively. Future climate patterns examined include the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emission Scenario (SRES) B1 and A1B groups. The Soil and Water Assessment Tool (SWAT) was employed to estimate total suspended solids and phosphorus concentration generated at a 10 year interval. The predicted results indicate that for a large portion of the watershed, the concentration of total suspended solids (TSS) would be higher under B1 and A1B climate scenarios during late winter and early spring compared to the same period in 2010; while the summer period largely demonstrates a reverse trend. Model results further suggest that by 2020, phosphorus concentration would be higher during the summer under B1 climate scenario compared to 2010, and is expected to wane by 2030. The projected phosphorus concentrations during the late winter and early spring periods vary across climate and land use scenarios. The analysis also denotes that middle and high density residential development can reduce excess TSS concentration, while the establishment of dense commercial and industrial development might help ameliorate high phosphorus levels. The combined land use and climate change analysis revealed land use development schemes that can be adopted to mitigate potential future water quality impairment. This research provides important insights into possible adverse consequences on surface water quality and resources under certain climate change and land use scenarios. 相似文献

A spatial autoregressive multinomial probit model for anticipating land-use change in Austin,Texas 总被引:1,自引:0,他引:1
This paper develops an estimation strategy for and then applies a spatial autoregressive multinomial probit model to account for both spatial clustering and cross-alternative correlation. Estimation is achieved using Bayesian techniques with Gibbs and the generalized direct sampling (GDS). The model is applied to analyze land development decisions for undeveloped parcels over a 6-year period in Austin, Texas. Results suggest that GDS is a useful method for uncovering parameters whose draws may otherwise fail to converge using standard Metropolis-Hastings algorithms. Estimation results suggest that residential and commercial/civic development tends to favor more regularly shaped and smaller parcels, which may be related to parcel conversion costs and aesthetics. Longer distances to Austin’s central business district increase the likelihood of residential development, while reducing that of commercial/civic and office/industrial uses. Everything else constant, distances to a parcel’s nearest minor, and major arterial roads are estimated to increase development likelihood of commercial/civic and office/industry uses, perhaps because such development is more common in less densely developed locations (as proxied by fewer arterials). As expected, added soil slope is estimated to be negatively associated with residential development, but positively associated with commercial/civic and office/industry uses (perhaps due to some steeper terrains offering view benefits). Estimates of the cross-alternative correlations suggest that a parcel’s residential use “utility” or attractiveness tends to be negatively correlated with that of commercial/civic, but positively associated with that of office/industrial uses, while the latter two land uses exhibit some negative correlation. Using an inverse-distance weight matrix for each parcel’s closest 50 neighbors, the spatial autocorrelation coefficient is estimated to be 0.706, indicating a marked spatial clustering pattern for land development in the selected region. 相似文献

Land use planning within and surrounding privatised Australian capital city airports is a fragmented process as a result of: current legislative and policy frameworks; competing stakeholder priorities and interests; and inadequate coordination and disjointed decision-making. Three Australian case studies are examined to detail the context of airport and regional land use planning. Stakeholder Land Use Forums within each case study have served to inform the procedural dynamics and relationships between airport and regional land use decision-making. This article identifies significant themes and stakeholder perspectives regarding on-airport development and broader urban land use policy and planning. First, it outlines the concept of the “airport city” and examines the model of airport and regional “interfaces.” Then, it details the policy context that differentiates on-airport land use planning from planning within the surrounding region. The article then analyses the results of the Land Use Forums identifying key themes within the shared and reciprocal interfaces of governance, environment, economic development and infrastructure. The article concludes by detailing the implications of this research to broader urban planning and highlights the core issues contributing to the fragmentation of airport and regional land use planning policy. 相似文献
