开发利用城市地下空间应充分考量其适宜性。本文以武汉长江新城为例,先提出了“适宜性=资源质量×开发需求”的适宜性评价模型,在此基础上分别介绍了地下空间资源质量和开发需求的评价方法以及指标体系;然后,结合长江新城多要素城市地质调查和总体规划的成果,开展了地下空间资源质量、开发需求和开发利用适宜性评价,得到了相应的分层评价分区图;最后,对评价结果进行分析,阐述了长江新城地下空间资源质量、开发需求及适宜性特征并提出了开发利用建议。研究成果不仅可以有效地服务于长江新城地下空间规划建设,而且建立了完整的地下空间开发利用适宜性评价体系,具有重要的理论和实践指导意义。 相似文献

海岛旅游地拥有丰富的旅游资源,然而当前我国海岛旅游地的开发呈现低层次和缺乏科学研究的盲目性。本文以加权线性组合方法构造模型,采用层次分析法建立海岛旅游地国土空间开发适宜性评价体系,选取自然条件、景观资源和社会经济等3大评价因素、9项评价因子分析浙江舟山普陀山海岛旅游地的国土空间开发适宜性。结果表明,普陀山适宜开发利用区、基本适宜开发利用区、限制生态开发利用区、生态保护区、禁止开发区等5种类型区域所占面积分别占全岛总面积的1.63%、17.04%、69.07%、8.66%、3.60%。本文根据实证结果,提出了普陀山海岛旅游地的国土空间利用优化策略、开发时序和规划功能结构。 相似文献

地下空间是城市实现可持续发展的重要资源。地质环境条件影响着地下空间资源的质量特征与发展难度,开发利用地下空间资源之前,需要对其进行科学评价。牡丹江市中心城区地下空间开发利用受区内地形地貌、岩土体工程地质、水文地质、环境地质问题和场地稳定性等多种因素影响。基于牡丹江市城市地质调查成果,建立了牡丹江市中心城区浅层地下空间(0~10 m)开发适宜性评价指标体系,按各指标的地质环境条件对研究区进行了分区,利用层次分析法(AHP)确定了各指标权重,最后通过ArcGIS空间分析功能对各指标分区图进行叠加,得出研究区浅层地下空间开发适宜性分区图。评价结果表明:牡丹江市中心城区浅层地下空间开发适宜性可划分为适宜性优区、适宜性良区和适宜性中区3个质量区。其中,适宜性优区和适宜性良区约占全区总面积的42.4%,分布于高平原地貌单元上;适宜性中区约占全区总面积的57.6%,主要分布于高漫滩地貌单元上。在该区开发利用地下空间时,建议提前做好该区的洪涝等灾害的防治工作。研究成果可为牡丹江市中心城区地下空间科学规划和合理开发提供参考。 相似文献

Taking Sichuan Gymnasium Station as the research object, we explore land use characteristics over time of areas around Sichuan Gymnasium Station in terms of time. We extract the basic information of land use in areas around Sichuan Gymnasium Station in 2005, 2011, and 2016 through Google Earth in order to draw the map of land use status in three time nodes. We then analyze the degree of mixing and equilibrium, intensity of development of land, and land use patterns of areas around Sichuan Gymnasium Station with indexes including the area proportion of land use patterns, information entropy, and degree of equilibrium within a 1,000-m radius centered on the station, so as to reveal the spatial distribution characteristics of land around the station in different time nodes. Through comparative analysis, it is found that the development of rail transit has not significantly contributed to the boom of commerce and the development of the old city of Chengdu. We also analyze land use changes in areas around Sichuan Gymnasium Station in terms of space, and find that land use patterns in areas around commuter stations seem to be more complicated than that of the average station, and land use patterns in areas around Huaxiba Station and Nijiaqiao Station on Line 1, which opened first, are more complicated than that of Moziqiao Station and Yiguanmiao Station on Line 3. The original land use patterns formed in the old city often determine the selection of rail transit routes and rail transit stations. Adaptive stations do not play a decisive role in land use patterns in their surrounding areas, but have some impact on the plot ratio and building height of land for commercial use within the core area of the stations. 相似文献

This paper gives insight into the use of underground space in Helsinki, Finland. The city has an undergroundmaster plan (UMP) for its whole municipal area, not only for certain parts of the city. Further, the decision-making history of the UMP is described step-by-step. Some examples of underground space usein other cities are also given. The focus of this paper is on the sustainability issues related to urbanunderground space use, including its contribution to an environmentally sustainable and aestheticallyacceptable landscape, anticipated structural longevity and maintaining the opportunity for urbandevelopment by future generations. Underground planning enhances overall safety and economy efficiency.The need for underground space use in city areas has grown rapidly since the 21st century; at thesame time, the necessity to control construction work has also increased. The UMP of Helsinki reservesdesignated space for public and private utilities in various underground areas of bedrock over the longterm. The plan also provides the framework for managing and controlling the city's underground constructionwork and allows suitable locations to be allocated for underground facilities. Tampere, the thirdmost populated city in Finland and the biggest inland city in the Nordic countries, is also a good exampleof a city that is taking steps to utilise underground resources. Oulu, the capital city of northern Finland,has also started to 'go underground'. An example of the possibility to combine two cities by an 80-kmsubsea tunnel is also discussed. A new fixed link would generate huge potential for the capital areasof Finland and Estonia to become a real Helsinki-Tallinn twin city. 2014 Institute of Rock and Soil Mechanics, Chinese Academy of Sciences.

In the urban sprawl paradigm, residential land use exhibits a more significant growth than other categories. Consequently, large proportions of the natural environment are converted to residential areas, particularly in tropical countries. Compact urban development is one of the most sustainable urban forms with environmental perspectives, such as rural development containment and natural environment preservation. However, no proper investigation of the relationship and influence of residential growth and city compactness is available. This study evaluated and forecasted the residential development of Kajang City in Malaysia based on compact development. First, the relationship between residential land use change and city compactness was evaluated. Second, residential growth was projected by utilizing the land transformation model (LTM) and the statistical-based weight of evidence (WoE) using various spatial parameters. Both models were evaluated with respect to observed land use and compactness maps. Results indicated that most of the newly developed residential areas were in zones where the degrees of compactness increase during certain periods. In addition, LTM performed better and provided a more accurate modeling of residential growth than the WoE. However, WoE provided clearer and more informative results than LTM in terms of functional relationships between dependent and independent variables related to city compactness. 相似文献

紧凑城市理论在南京城市总体规划修编中的运用 总被引:1,自引:0,他引:1
研究认为紧凑发展是当今国际较为流行的先进城市规划理念,也是人地矛盾较为尖锐的中国城市化的必然选择。紧凑城市理论的核心是节约集约用地,促进人口经济与环境协调发展,与我国倡导的科学发展观在本质上是一致的。新一轮南京城市总体规划修编工作,根据南京的自然条件特点探索应用紧凑城市理论,在宏观层面提出严格控制建设用地规模,在城镇建设用地形态上强调紧凑布局,在街区层面强调功能多样性,在用地策略上强调公共交通引导土地开发。最后,对我国如何有效学习借鉴紧凑城市理论提出了相关意见和建议。 相似文献
