土地利用战略研究是新一轮土地利用总体规划的重要内容,但目前的土地利用战略研究多是从区域整体角度进行分析,未体现区域内部空间差异,对制定差异化土地政策的指导性不强.土地利用战略分区研究可使分区结果与土地政策调控形成互动机制,提高其指导性,从而促进区域土地合理利用与有序开发,实现区域统筹发展.对土地利用战略分区的主要研究内容与原则、指标体系选择、研究方法与思路等进行了探讨,希望对完善土地利用战略及分区研究有所裨益.  相似文献

在土地利用分区的背景下,以皖江城市带为研究对象,基于2012年皖江城市带各地级市土地生态安全的相关数据,从压力、状态和响应3个方面构建皖江城市带土地生态安全评价指标体系,对各土地利用分区的土地生态安全状况进行分析。结果表明:1皖中区除了六安的土地生态安全等级为"较安全"外,其余都处于"危险"级;沿江区中安庆处于"较安全"级,芜湖和马鞍山处于"危险"级,铜陵处于"预警"级;皖南区除宣城处于"预警"外,其余均处于"较安全"级。2皖江城市带土地生态安全东西分异明显,且各区内影响土地生态安全水平的指标各不相同。针对评价结果,提出了调控土地生态安全水平的措施与建议:皖中区应将改善土地生态安全状态和集约用地放在首位,沿江区应将提高土地利用效益放在首位,皖南区应坚持生态优先、适度开发。  相似文献

土地是重要的自然资源和基本的生态环境要素.土地利用在很大程度上决定了施加于环境的压力.农业贫困县面临经济与生态发展的双重压力,更需要进行生态功能区划,寻找合理的土地利用模式,避免走向"先污染,后治理"的老路.以典型的农业贫困县延寿县为例,充分考虑当地的自然经济条件,运用叠置法对其进行了综合分区,将其分为中部沿河平原农渔牧复合区、南北山前漫岗水土保持及农林区、南北低山丘陵林业可持续利用区3个生态功能区,并针对不同区域土地资源的特点,探讨了各区的环境友好型土地利用模式,提出了土地资源区域治理措施和土地利用的方向.  相似文献

构建土地利用规划环境影响评价的指标体系   总被引:25,自引:0,他引:25  
冯春涛 《资源开发与市场》2004,20(6):416-417,420
20世纪90年代中期,土地科学界和生态学界曾提出:"无论将土地作为生产性利用还是非生产性利用,都会形成一种干扰,使生态环境的不确定性增大,从而降低土地利用规划的科学性和合理性".在这一背景条件下,尝试性地按照土地利用类型对其所带来的环境变化影响与效应进行了分析,并在此基础上构建土地利用规划环境影响评价指标体系及可采用的评价方法.  相似文献

This study analysed the importance of physical forces on land-use change, on the planning framework in a Portuguese periurban area. A temporal matrix showing the trajectories of land transformation was obtained. A multivariate redundancy analysis explored the importance of physical parameters on temporal and spatial land-use change. A content analysis on urban or municipal master plans was made framing the importance of physical parameters on the planning process. The results highlighted a consistent trajectory of profound land-use changes with distinctive trajectories, with increasingly complex patterns with a limited dependence on physical variables. The trajectories were more related to the planning framework, where political actors and planning managers seemed to be most important. A theoretical model balancing three main components – physical forces, actors, and land transformation (DFA-C model) is proposed, reflecting the informal relationships between physical parameters and actors during the planning process.  相似文献

There is tenure insecurity around land ownerships and land rights in most developing countries. There are also many land-use planning projects being implemented in these countries. Often, land-use planning exists in these countries but is not formally linked with tenure security. This study argues that combining them by conducting land-use planning in a way that promotes tenure security presents a new approach. A central premise for the rationale of this intervention is that processes of land-use planning may inadvertently increase tenure security. By way of methodology, it evaluates land-use planning case studies from Africa, Asia and South America. It uses the three case study examples to build a case for making tenure security one of the major planned outcomes of a land-use planning process and provides a detailed framework for operationalising the concept. Its main contribution to the literature is that it introduces the concept of tenure responsive land-use planning.  相似文献

Oregons land-use planning program is often cited as an exemplary approach to forest and farmland conservation, but analyses of its effectiveness are limited. This article examines Oregons land-use planning program using detailed spatial data describing building densities in western Oregon. An empirical model describes changes in building densities on forest and agricultural lands from 1974 to 1994, as a function of a gravity index of lands commuting distance to cities of various sizes, topographic characteristics, and zoning adopted under Oregons land-use planning program. The effectiveness of Oregons land-use planning program is evaluated based on the statistical significance of zoning variables and by computing estimated areas of forest and agricultural lands falling into undeveloped, low-density developed, and developed building density categories, with and without land-use zoning in effect. Results suggest that Oregons land-use planning program has provided a measurable degree of protection to forest and agricultural lands since its implementation.  相似文献

TIM: Assessing the sustainability of agricultural land management   总被引:1,自引:0,他引:1  
TIM (Threat Identification Model) is a framework for the ex ante assessment of agricultural land management sustainability at the land unit scale that identifies sources of unsustainability within agricultural land management systems. The model explicitly links defined hazards to land productivity and environmental integrity, land resource data and information, and land management practice options using expert and local knowledge on land management and its potential effects. The model was tested in the Crystal Creek Subcatchment, a narrow coastal strip of land situated in north Queensland, Australia. This area was chosen due to the expansion of the sugar industry onto increasingly marginal land in the area, which represents a threat to sustainable land use and a requirement for careful land-use planning and land management.TIM may be used in a relational database as a stand alone decision support system for land-management planning. Its usefulness in land-use planning is greatest when it is linked to a Geographic Information System (GIS) as shown in this paper. GIS allows TIM outputs, such as constraints to agriculture and site-specific best-management practices, to be identified in a spatially explicit manner.The main advantages of TIM are that it can be done ex ante, it removes the need to define sustainability assessment criteria and indicators, it utilises current understanding of the causes and effects of land degradation and how different land-management practices influence these, and links this knowledge to definite land-management options.  相似文献

The paper explores the roles of environmental movement organisations (EMOs) in land-use planning, including domain creation (establishment of new or modified landscape planning boundaries) and regime change (adoption of new or modified legal and planning rules). The research involved two case studies of land-use planning processes: the Niagara Escarpment and Oak Ridges Moraine, Ontario, Canada. The two cases together reveal an evolution of land-use planning towards collaborative processes on mainly private lands in Southern Ontario during the period from 1960 to 2002. The results suggest that EMOs can create new planning domains through agenda setting activities, build landscape value and vision, educate governments and the public, and work to maintain and alter regimes. Collaborative planning has emerged as an important process in which some EMOs are now participating.  相似文献

This research investigates the use of an Assessment of Ecosystem Services (AES) approach as a planning tool in Florida through the use of an online survey. Target respondents were professionals who had been involved in AES projects. The majority of the respondents perceive an AES approach as a comprehensive and holistic approach that results in better land-use planning decisions. However, AES does not appear to be widely used to guide planning decisions. Despite some challenges, respondents across multiple agencies and institutions in Florida are supportive of using AES in combination with traditional land-use planning tools. More rigorous testing and validation and clarification of guidelines for best practice could improve political and economic support and thereby facilitate the use of AES to guide land-use planning efforts.  相似文献

基于Markov模型的南京土地利用时空变化研究   总被引:1,自引:0,他引:1  
利用江苏2000年、2008年遥感数据,采用ArcGIS和Excel测算出南京市辖区8年土地利用的Matkov转移矩阵,从数量、空间和结构角度分析2000-2008年的土地利用变化状况,预测2016年的各类用地面积.结果表明,2000-2008年研究区的城镇和工矿交通用地扩张较快,农村居民点用地略有减少,呈集中态势;耕地、草地、林地、水域减少,未利用地减幅最大.在空间上,研究区的建设用地扩张由"同心圆状"变为"纺锤状",土地利用集中度和强度都增大.2016年预测显示,城镇用地比重达44.76%,耕地减少23.47%,其余用地基本保持前8年的变化趋势,但动态度有所减小,仅农村居民点用地减幅增大.  相似文献
