我国土地资源短缺,城市化初始阶段非农建设用地扩张严重,与此同时,城市存量土地却存在粗放利用现象。因此,必须挖掘城市用地潜力,提高土地使用效率,实现城市土地集约利用。在分析武汉市城市土地集约利用现状的基础上,以全国19个市区非农人口在200万人以上的城市为评价单元,进行区域比较分析来反映武汉市城市土地集约利用整体水平。同时针对武汉市城市土地集约利用中存在的问题,提出若干有益于土地集约利用的对策和建议。 相似文献

城郊土地利用的社会经济效益和生态环境效益之间存在耦合关系,对二者的协调耦合度进行研究,可以有效评价城市扩展的合理性。本文根据系统科学理论与方法,对1998—2011年武汉市远城区土地利用社会经济效益与生态环境效益综合值进行测算,分析了二者的耦合动态。结果表明,研究期内,武汉市远城区土地利用社会经济效益和生态环境效益均呈增长趋势,但后者增速较缓且有波动性。从土地利用效益耦合度演化曲线来看,武汉市远城区土地处于协调发展阶段,但近年来耦合度有不断上升的趋势,这意味着武汉市未来远城区土地利用效益可能进入极限发展阶段。 相似文献

研究目的:明确土地经营权入股合伙模式的类型并提出规制建议。研究方法:采用文献分析法和案例分析法。研究结果:(1)正确处理合伙模式与其他土地经营权流转制度的关系,注意区分合伙模式与土地经营权出租,以及合伙模式在一定程度上可以替代有限责任公司模式。(2)明确确保入股的土地经营权权利没有瑕疵是土地经营权人的法定义务,从而保障合伙能够正常从事农业经营。(3)确定土地经营权入股合伙模式的法律性质是物权流转,合伙财产属于合伙人共同共有,以便合伙人可以通过土地经营权抵押贷款,解决资金困难。研究结论:土地经营权入股的合伙模式是土地经营权入股的重要模式,不能为股份合作社模式、农民专业合作社模式、有限责任公司模式所替代。 相似文献

房价、地价与土地供应的前因后果 总被引:6,自引:0,他引:6
近年来,征地费用和拆迁费用越来越高,加大了土地取得成本,这种成本的升高,和土地出让方式是无关的。更重要的是,熟地价远远高于毛地价,由此导致的成本差异很大,对房价的影响迥然不同,不加区别地推论地价上涨对房价的影响是不科学的。就近期而言,土地供应量并没有大幅度减少。“三个暂停”以来,全国各地土地征占用数量有所减少,出现了“土地紧缩”,但是主导房地产开发的国有土地出让基本上没有受到影响,反而由于“8·31”大限,一些地区还呈现了大幅度增长的趋势。无论是协议出让还是招拍挂,都是土地市场中的资源配置方式,也可以说是一种形式。这种形式上的改革,充分体现了公开、公平、公正的原则。从对地价和房价影响的角度看,形式毕竟是形式,不会从本质上改变土地市场中最基本的供求矛盾,因而不能在根本上决定地价和房价的高低。 相似文献

我国城市用地扩展与土地集约利用 总被引:5,自引:0,他引:5
分析了我国城市用地增长弹性系数和城市用地扩展幂指数规律,发现土地利用效益偏低、扩张速度偏快是目前我国城市用地扩展的主要特征;分析了城市用地扩展的主要驱动力,发现固定资产投资和人口增长是城市扩展的主要动力,而第三产业发展有助于抑制城市用地扩张;认为城市扩展是我国现阶段经济发展的必然结果,但我国城市土地利用应变外廷扩展为外延扩展和内涵挖潜相结合的利用方式,提高土地利用的集约度与综合效益. 相似文献

节约集约用地是现阶段国土资源管理工作的重中之重。土地登记作为国土资源管理的一项基础性工作,为国家掌握土地动态变化提供重要的信息,同时,它又是土地用途管制制度的重要组成部分,也是国土部门的一项主要管理职能。当前,研究和探索土地登记制度改革,规范土地登记行为,加强土 相似文献

Land-use models express the relationship between various driving forces of land-use changes and are increasingly employed in practical applications to predict possible future land uses. The relationship between the agricultural land market and land-use changes is often neglected in such models. The objective of this study is to assess the production values of agricultural land to be integrated in an operational land-use model with the aim to improve understanding of land-use changes in all 28 European Union countries. This economic evaluation of agricultural land is based on the Net Present Value (NPV) method, a method that aims at uncovering the operational production values of land rather than real estate market value. The scientific relevance of this work is the development of a comprehensive methodology for the economic evaluation of agricultural land uses in different EU countries, the integration of economic production values of land to the local suitability approach in the studied land-use model and the provision of a EU-wide database of the NPVs of agricultural land uses, including various energy crops. 相似文献

The role of land tenure in agricultural development has been a subject of intensive research, particularly within the context of land and agrarian reform. The complexity of the world's major land tenure systems is well recognized and no attempt is made here to go beyond an overview as this paper limits itself to the impact of land tenure on land use in low income situations. Present land use is determined by a host of factors, of a physical/biological and socioeconomic nature. In applying land evaluation, the question it is necessary to ask is to what extent, when and where land tenure conditions act as a considerable constraining factor impeding a more optimal use of land resources. Even in what used to be low-population density areas (such as Sub-Saharan Africa) it appears that the frontier phase is becoming exhausted and the intensification of agriculture proceeds; it becomes imperative to examine land tenure in relation to land use implications. It is shown that so far a multi-disciplinary approach has often been lacking in treating land tenure and related issues. 相似文献

This study investigates attitudes towards legalizing land sales and Willingness to Accept (WTA) sales prices and compensation prices for land among smallholder households in the southern highlands of Ethiopia. Household panel data from 2007 and 2012 are used. The large majority of the sample prefers land sales to remain illegal, and the resistance to legalizing land sales increased from 2007 to 2012. While resistance against land sales was strongest among the most land poor in 2007, the relatively more land rich had become more negative towards legalizing land sales in 2012. Younger age and more education were not associated with a more positive attitude towards legalizing land sales. In the same period, perceived median real land values increased sharply but also exhibit substantial local variation with higher land values in areas with better market access. Stated minimum land sales prices increased with farm size in 2012. The substantial increase in perceived land values, high economic growth and outmigration of youth have yet to persuade the rural population in southern Ethiopia to open the land sales market. 相似文献

We solve Faustmann's problem when the land manager plans to switch from the current tree species to some alternative species or land use. Such situations occur when the value of the alternative increases relative to the value of the species currently in place. The paper characterizes the land value function and the optimum rotations, highlighting the differences between this non-autonomous problem and the traditional Faustmann problem. We show that, from one harvest to the next until the switch, rotations can be constant and equal to the Faustmann rotation, or increasingly higher than the Faustmann rotation, or decreasingly lower. In the last two situations, the higher the number of previous harvests of the currently planted species before the switch to the alternative use, the closer the last rotation is to the Faustmann rotation. 相似文献

This article looks at the role land reclamation can play in increasing food output, alleviating hunger, reducing costs of food imports and creating employment. There are many problems associated with this practice, however, such as the low productivity of reclaimed land, the conflict between growth of subsistence versus cash crops, and the economic viability of schemes implemented thus far. It appears that a new definition of economic viability is necessary before assessing whether or not reclamation projects are feasible. 相似文献
