Segmentation of the Housing Market and its Determinants: Seoul and its neighbouring new towns in Korea

This study identifies the spatial pattern of housing price changes and their determinants in Seoul and its neighbouring new towns. The results of a cluster analysis show that the spatial pattern of housing price change rates is nor correlated with housing prices. It is found that housing price change rates vary with the Chonse price index and money supply, building permit area, stock price index, and yield on 3 year corporate bonds. It is also shown that the more apartment units that are built in a region, the lower the housing price change rate.     

南京市区地价空间分布及其影响因素分析

根据南京市1998年的出让地价资料,在Access中建立地价样点数据库,并同MapInfo间建立链接,在Map Info中得出住宅地价和商业地价等值线图,分析南京市区地价变化同主要区位因子的关系,在统计学软件SPSS中得出相关模型,并对结果进行解释。     

战后日本土地价格的变化特点及其成因分析

战后,日本的土地价格持续上涨,出现所谓“土地必定升值”的土地神话。特别是在80年代中后期的地价高涨中,以东京为首的几个大城市区域的地价一下子上涨了数倍之多。但是90年代初地价开始暴落,长期流行的土地神话终于沉寂。本文从地理学的角度出发,考察研究日本战后土地价格发展变化的时空分布特点,并分析探讨各种要素对地价涨落及其时空分布特点形成的影响。     

国际金价走势及对策

在世界金矿资源勘查、黄金生产、黄金储备和黄金消费资料分析的基础上,作者就金价下跌、我国金价与国际全面接轨对我国特别是对地勘行业的黄金勘查和生产状况的影响进行了分析。作者认为,世界巨量黄金储备是制约目前国际黄金价格的主要因素。但在黄金价格已接近或低于生产成本线的情况下,金价的下跌幅度有限,亦不会长久。我国的黄金企业只有采取规模经营和苦练内功等,方能降低生产成本,提高经营效益,才有资格参与国际竞争。     

内插地价监测点进行土地级别调整的研究

针对城镇基准地价更新中土地级别范围调整问题,提出了内插地价监测点调整土地级别技术在建立地价动态监测体系的基础上,运用合适的空间内插模型,通过插值计算得到城镇内每个点的地价,然后根据一定的地价幅度生成等值线图,进而由地价等值线图结合原有土地级别进行土地级别范围的确定和调整。     

长江上游退耕还林工程合理规模与模式

陡坡耕地的水土流失对生态环境和农业可持续发展构成双重压力。退耕还林是促进人与自然协调，推动农业可持续发展的有效途径，但应避免退耕还林工程规模的盲目扩大。退耕还林的规模应根据自然条件、生态功能定位并考虑粮食安全保障以确定。地广人稀的金沙江中上游、盆周山地是长江上游最重要的水源涵养、水土保持功能区，其退耕还林规模可适度扩大，但川中丘陵区、三峡库区人口稠密，退耕还林不应过分追求规模，退耕后的林草地不应突破土地面积的40％。而退耕还林工程的实施更应注重模式的选择，防止一刀切，川中丘陵区、三峡库区退耕还林宜采用“旱坡地粮经弹性结构种植”技术，建立坡地农林复合系统，逐步实施退耕还林。     

分时电价下多用途水库的运用方式研究

提出了考虑丰枯、峰谷分时电价因子的多用途水库水电站优化调度模型,并应用遗传算法求解.通过四川省紫坪铺水库的运用研究表明,是否考虑分时电价对水库的运用方式会产生较大影响.分时电价调度模型可使电站可靠出力提高,能够达到水资源合理利用,有利于调节水电站开发,并能较好地协调发电与供水矛盾,具有推广应用价值.     

浅谈枣庄市市中区基准地价成果分析及应用

城区土地级别和基准地价是城市土地利用情况的反映,它客观地揭示了城区内不同区段土地使用价值及变化规律,是政府宏观调控土地市场、科学合理配置土地资产的有效手段。随着枣庄市市中区经济建设发展和城市规划的实施,城市基础设施不断完善,带动了城市房地产市场健康发展和土地使用权价格稳定上涨。该文通过对枣庄市市中区新一轮基准地价更新成果的详细分析,探讨了基准地价更新成果在城市经济发展中的应用。     

基于城市引力模型与随机扩散方程的城镇基准地价平衡(英文)

A balance of urban datum land prices is achieved to harmonize regional land prices and make the prices truly reflect different economic development levels and land prices among cities. The current piecewise linear interpolation balance method widely used has two drawbacks that always lead to an unsatisfactory balance among some cities. When the excess of land price in the central city to the surrounding zone reaches a certain degree, land price in the circumjacent city is not only consistent with the local land grade and land use level, but also influenced by the diffusion of land price in the central city. Thus, a new balanced scheme of datum land prices based on the city gravitation model and stochastic diffusion equation is brought forward. Finally, the new method is examined in the practice of datum land price balance in Hubei Province, China.     

Application of Three-Dimensional Laser Scanning and Surveying in Geological Investigation of High Rock Slope

The appearance of 3D laser scanning technology is one of the most important technology revolutions in surveying and mapping field. It can be widely used in many interrelated fields, such as engineering constructions and 3D measurements, owing to its prominent characteristics of the high efficiency and high precision. At present its application is still in the initial state, and it is quite rarely used in China, especially in geotechnical engineering and geological engineering fields. Starting with a general introduction of 3D laser scanning technology, this article studies how to apply the technology to high rock slope investigations. By way of a case study, principles and methods of quick slope documentation and occurrence measurement of discontinuities are discussed and analyzed. Analysis results show that the application of 3D laser scanning technology to geotechnical and geological engineering has a great prospect and value.
