论我国土地征收补偿制度之完善

我国征地补偿标准以耕地常年产值为依据,以被征地农民的利益为代价来换取城市的发展建设,与当前我国的市场经济体制不相适应.发达国家的土地征收补偿制度为我国土地征收补偿制度的完善提供了宝贵借鉴.我国土地征收补偿制度可通过提高补偿标准、完善土地征收补偿方式、建立和完善失地农民社会保障制度等方式逐步完善.     

高密度开发城市土地利用对交通系统的影响作用研究--以广州为例

Recently the study on the mutual relationship between urban transport and land use has been one of the hot subjects in the fields of urban geography, urban transport planning and urban planning. This paper tires to carry out some methods, such as multi-analysis statistics method to specify the impacts of urban land use on urban transport system. Firstly,the choice of urban transport road network affected by the characters of urban land use layout is discussed. Secondly, the promotion of urban public transportation affected by high-density concentrated land use pattern is demonstrated Thirdly, the impacts of urban city-size on transport system structure characters are expatiated. Finally, the impacts of urban master planning in Guangzhou on the layout of transport system are illustrated.     

保障我国农民土地收益的制度分析

近年来，由于制度安排的缺陷，我国农地大量转非，农民利益受到损害，导致大量失地农民出现，危及粮食安全和社会稳定。当前，尽管中央对土地进行了严格管理，但是只是临时政策性的措施。要从根本上解决这些问题，必须从制度创新上寻求可行的途径。为此，本文通过对农民土地利益损失的制度原因分析，并对农地制度固化和创新的风险以及几种可供选择的制度创新方案比较后，认为渐进式的制度改革是符合我国的现实选择。     

区域产业结构调整与土地可持续利用关系研究

文章通过实证分析方式阐述了区域经济发展与土地利用相互关系，着重分析了我国非农产业发展的不同阶段耕地占用状况的变化，在此基础上，进一步分析了区域经济系统产业结构升级与用地结构的变迁关系，尤其是“十五”期间我国产业结构的进一步升级，将在一定程度上进一步带动农业用地的非农化，同时还可能会造成土地污染问题，据此作者认为我国产业经济的可持续发展必须以土地资源可持续利用为基础，并提出了推进我国可持续发展的战略实施的土地资源可持续利用政策体系。     

我国土地征用制度探讨

国家为了公共利益的需要,可以依法对土地实行征用,但是这种征用必须符合公共利益、给予公平补偿、满足正当程序的要求。完善我国土地征用制度应该在这三个方面着手。

A Semiparametric Method for Valuing Residential Locations: Application to Automated Valuation

This paper is motivated by automated valuation systems, which would benefit from an ability to estimate spatial variation in location value. It develops theory for the local regression model (LRM), a semiparametric approach to estimating a location value surface. There are two parts to the LRM: (1) an ordinary least square (OLS) model to hold constant for interior square footage, land area, bathrooms, and other structural characteristics; and (2) a non-parametric smoother (local polynomial regression, LPR) which calculates location value as a function of latitude and longitude. Several methods are used to consistently estimate both parts of the model. The LRM was fit to geocoded hedonic sales data for six towns in the suburbs of Boston, MA. The estimates yield substantial, significant and plausible spatial patterns in location values. Using the LRM as an exploratory tool, local peaks and valleys in location value identified by the model are close to points identified by the tax assessor, and they are shown to add to the explanatory power of an OLS model. Out-of-sample MSE shows that the LRM with a first-degree polynomial (local linear smoothing) is somewhat better than polynomials of degree zero or degree two. Future applications might use degree zero (the well-known NW estimator) because this is available in popular commercial software. The optimized LRM reduces MSE from the OLS model by between 5 percent and 11 percent while adding information on statistically significant variations in location value.     

我国农村土地制度的产权经济分析

近年来我国农村发生了土地制度的深刻变革,变革的核心是土地产权制度的变迁。这种制度变迁在某种程度上具有帕累托改进的性质,但在某些方面还有待于发展和完善。我国农村土地产权制度建设的思路:以现行产权制度为基础,通过修订和完善,不断发挥现行产权制度的积极作用。     

Anthropogenic and topographic correlates of natural vegetation cover within agricultural landscape mosaics in Turkey

Natural vegetation enhances the value of agricultural landscapes for people and wildlife. However, the role of anthropogenic versus topographic factors in driving the extent of natural vegetation cover within agricultural lands at large spatial scales remains unexplored. I assessed the influence of anthropogenic and topographic variables on the extent of agricultural mosaics with high natural vegetation cover in the country of Turkey where a large extent of natural and semi-natural vegetation is maintained by traditional agriculture. GIS layers depicting human land use, elevation, slope, roads and population data were obtained and summarized at two spatial scales, within provinces and for 100 km² grid cells covering the country’s entire agricultural land area. Average farm size was also obtained at province level. Hierarchical Partitioning was conducted to determine the independent effect of anthropogenic and topographic variables on the variation in agriculture with high natural vegetation. Slope had the largest independent effect on the variation in the proportion of agricultural mosaic with high natural vegetation cover. The extent of agricultural and settlement area also explained much of the variation in natural vegetation across both grid cells and provinces. The proportion of natural vegetation increased as human population and road density decreased across grid cells and as average farm size decreased across provinces. These results suggest that while topography is the primary driver of natural vegetation cover within agricultural mosaics in Turkey, the pressures associated with urban development and agricultural industrialization may also influence the cultural and wildlife value of agricultural landscapes.
