城镇用地扩张的弹性规划控制研究——以安徽省滁州市南谯区为例

采用双因素预测模型、主成分聚类分析法、建设用地生态适宜性评价等方法,研究城镇用地扩张的规模和空间布局规划控制,以探讨具备适度弹性的城镇用地扩张规划控制的内容及模式。基于扩张经济和人口增长驱动双因素,运用GDP、非农人口弹性预测及单位用地GDP、单位用地非农人口控制构建扩张规模弹性方案预测模型;考虑经济社会发展和节约集约控制需求,选取扩张弹性控制等级分区指标,划分由相对扩张到相对收缩、有弹性到无弹性的分级弹性控制区,结合建设生态适宜性评价结果,识别城镇空间有序发展方向。结果表明:弹性控制方案下南谯区2010、2015、2020年建设用地扩张规模弹性度分别为5.81%、7.25%、8.34%,并将其划分为四级扩张弹性控制区,东南方向为扩张有序方向。     

建设用地需求量预测方法比较研究——以广西壮族自治区永福县为例

建设用地需求量预测是土地利用总体规划修编的重要组成部分,选用合理的方法准确预测规划目标年的建设用地需求量具有重要意义。分析比较了双因素预测法、趋势预测法和GM(1,1)模型法预测建设用地需求量的特性与适用条件,以广西壮族自治区永福县为例,对建设用地需求总量预测进行了实证研究。结果表明:GM(1,1)模型法在县域建设用地需求量预测中具有较好的精度,更符合县域经济的发展。该研究成果可为新一轮土地利用总体规划修编中建设用地趋势变化分析以及需求量的确定提供借鉴参考。     

建设用地扩张影响因子的选取及分析

研究建设用地规模扩张的影响因子,并选取相关性较显著的因子,与建设用地间建立合理的多元回归模型,拟合建设用地发展趋势,可对用地扩张规模及需求进行预测.通过对某市历年统计数据中的诸多影响因子进行相关分析,筛选剔除存在多重共线性以及与建设用地相关性较弱的因子,建立科学的多元回归模型,并与灰色GM(1,1)模型法的结果作比较.结果表明,所选取的驱动因子合理,其与建设用地扩张的趋势相适应,所建立的多元回归模型可靠,可较好的拟合用地的发展趋势.     

城市建设用地规模预测方法与应用研究

合理确定城市用地规模,是衡量城市理性发展的重要依据。将灰色关联度引入城市建设用地的预测中,通过对双因素理论模型进行改进,建立建设用地规模的预测模型,通过对哈尔滨市2010年以及2020年城市建设用地规模进行预测,得知哈尔滨市的建设用地规模将会急剧扩张,这样势必会占用宝贵的耕地。抑制用地规模急剧扩张的势头,应采取挖掘城市存量土地的潜力,注重城市内涵发展,正确处理保护耕地与城市发展的关系,在加强土地用途管制的同时增加规划控制的灵活性与弹性。     

创新集体建设用地使用权流转制度的思考

农村建设离不开土地资源这个重要载体,需要土地、资金等保障和支撑。而集体建设用地使用权流转所存在的内在障碍,恰恰正是新农村建设普遍遇到的突出矛盾。虽然集体非农建设用地使用权流转受到法律的严格限制,但流转仍呈现了相当的规模。集体建设用地流转由于在法律政策上未得到明确的认同．缺乏合理的规制,容易滋生土地纠纷,因此将农村非农建设用地纳入市场规范流转势在必行。本文正是在这样的背景下开展对创新非农集体建设用地使用权流转的研究,对规范集体建设用地使用权流转提出若干设想和制度设计。     

农村集体非农建设用地直接上市:市场失灵与其政策矫正

研究目的:研究中国农村集体非农建设用地直接上市陷于困境的制度之源,探讨农村集体非农建设用地直接上市的政策矫正。研究方法:局部均衡分析和交易费用分析。研究结果:中国现行法律法规对农村集体非农建设用地直接上市限制不当以及集体非农建设用地产权残缺提升了市场交易费用,减弱了当事人的集体非农建设用地供求,影响了交易效率,降低了社会福利。研究结论:必须"尊重农民土地财产权利",在明晰农村集体非农建设用地产权基础上,赋予农村集体非农建设用地直接上市的权利,从消除制度障碍、明晰土地产权等角度克服中国集体非农建设用地直接上市的瓶颈。     

新农村建设中非农建设用地制度改革探讨

本文认为,促进社会主义新农村建设需要新的非农建设用地制度的支撑。应顺应农村非农建设用地制度改革趋势,允许农村非农建设用地进入市场。而大量的改革试验和探索已为此储备了政策和法律空间,允许农村非农建设用地进入市场的时机已成熟。     

构建城乡统一建设用地市场的法治保障分析

近年来城乡用地矛盾日益突出,城市建设用地日益匮乏,但是农村集体建设用地却是闲置浪费,因此急需土地生产要素在城乡之间来回流动。但是现今我国实行的是城乡二元体制的土地管理体制,城乡土地所有权分别归国家和农村集体组织所有,因此导致农村非农用地与城市建设用地市场分割,农村非农土地不能进入市场,这严重阻碍了社会经济的发展,也产生了众多的社会矛盾,因此急需构建城乡统一的建设用地市场。本文从梳理我国城乡建设用地市场现状和存在的问题出发,在分析我国构建城乡统一建设用地市场的必要性的基础上,提出构建我国城乡统一建设用地市场的法治建议。     

县级土地利用总体规划中非农建设用地指标分解——以湖北省谷城县为例

通过对县级土地利用总体规划中非农建设用地指标分解的方法进行探讨.阐述了非农建设用地指标分解的意义和原则,以谷城县为例,提出采用因素因子综合评分法来划分非农建设用地指标,以最大限度满足各乡镇各类用地需求为原则,结合该县相关政策和各乡镇土地利用需求状况对指标分解结果进行了调整.     

江苏城乡建设用地特征及对策研究

江苏省1991-2007年城乡建设用地现状特征为:村镇建设用地比例过高,人均建设用地水平与城镇规模大致呈反方向变化,城市内部用地结构部分失衡.城乡建设用地扩张特征为:城乡建设用地呈加速增长趋势,城市与农村建设用地并行增长,城市建设用地增长的分级差异明显,工业和居住用地高速扩张.江苏城镇建设用地存在建设用地粗放增长,规模不断扩大,村镇建设用地比例过大,城市内部用地结构失衡等问题.建设用地理性增长需要进一步控制.控制城乡用地增长速度,提高城镇建设用地效率,推进城乡居民点用地的整理改造.

Similarities and dissimilarities between the EU agricultural and rural development model and Romanian agriculture. Challenges and perspectives

The main aims of this study are to highlight the differences and the similarities between the European model of agricultural and rural development, and the state of play in the Romanian agricultural sector. Statistically speaking, the agricultural sector's indicators of the past two decades place Romania outside the family picture of the EU countries, with very slight resemblances, and very strong discrepancies between their economic, technical, and institutional characteristics. At present, competition-wise, farming and farmers in Romania are still strongly disfavoured in relation to their competitors in the old EU Member States. In Romania, the economic and institutional mechanisms have most often been devised to the disadvantage of agricultural production, by claiming that subsistence farming would be the sustainable way, and by channelling the added value to other sectors. An option to continue the agricultural policies of the past decades and to abandon the national support lent to agriculture would be particularly risky through its unpredictable and incalculable social and economic effects.     

Land use planning and health and well-being

This paper is concerned with the relationship between the planning of settlements and health. It gives a brief introduction to the issues before summarising the evidence in relation to a range of topics, concluding with some more speculative thoughts on likely future findings.Modern planning was invented in response to inhumane living conditions in 19th century cities. But in the last century the connection was lost. Only now, with concerns over climate change and obesity, is there beginning to be the realisation that the physical environment is an important determinant of health.The paper uses a particular model of this relationship based on eco-system and health determinants theories to structure the review of evidence. The review covers: lifestyle choices in relation to physical activity and diet, mental well-being and community, the local economy and income, health inequalities and strategic land use transport planning, pollution and urban form, and finally impacts on global ecology.There is now a growing consensus that while personal factors are critical in determining health, the urban environment exacerbates or mitigates health and well-being outcomes.The level of active travel (walking and cycling) and outdoor recreational activity is strongly affected by accessibility to local facilities. Access to green, natural environments, and to local social networks, are factors in mental well-being. The wider sub-regional pattern of housing, economic development, land use and transport is a determinant of social exclusion and therefore health inequalities. It also affects health-damaging pollution, adaptability in the face of climate change and the level of carbon dioxide emissions.We have literally been building unhealthy conditions into many of our towns and cities. But comparisons with the best cities in Europe indicate that it is possible to reverse the less desirable trends. Success depends, however, on more radical policies of local authority control over land and finance than any political party has yet advocated. It also requires collaboration between the full range of powerful public and private organizations that influence the built environment.Future research is likely to further strengthen these conclusions. It will become much more obvious that planning for health and well-being is not only the NHS, but about creating a health-promoting physical, social and economic environment.     

Mix and sequencing of economywide and agricultural reforms: Chile and New Zealand

Once committed to economywide and sectoral reforms – stabilization, structural adjustment, and trade liberalization – and companion reforms of institutions, how does government best proceed? With what reforms in response to initial conditions, and in what mix, sequence, strength, and speed? This study examines what factors were most critical to success during transition in two early reformers. The economies of Chile and New Zealand have undergone seismic reforms, starting in the mid-1970s and 1980s, respectively. Comparative analysis of their reforms look at the prior conditions that induced drastic action and the policy choices made in each country. Though similar in many respects, differences in initial economic conditions and implementation led to dissimilar, even contrary results. For Chile, the outcome was a vigorous, recharged economy and agricultural sector; for New Zealand, the economy and the sector are lagging still. How policy choice and implementation, as well as simultaneity of reforms, affected the outcomes is the major thrust of the study. The preeminence of trade and macroeconomic policies over sectoral interventions, and in particular the strategic nature of the real exchange rate in allowing agriculture to compete domestically and internationally highlight the discussion.
