城市基准地价评估的容积率内涵及其修正系数的确定--以石家庄市为例

基淮地价评估是当前城市地价评估的主要形式。容积率既反映了土地的利用状况，同时也是影响地价的主要因素之一。该文阐述了容积率内涵，分析容积率与地价、环境的关系，探讨合理容积率的确定，以石家庄市为例，探索容积率修正系数确定的正确途径，避免在容积率概念、修正系数等问题上产生混淆。     

GPS在地面沉降监测中的应用探讨

利用GPS进行地面沉降监测能够解决传统测量方法工作量大、周期长的问题。该文结合实例，论述了GPS在地面沉降监测中的应用，分析了GPS测量方法的优点和误差，提出了GPS测量地面沉降的适用条件。     

东莞城市化过程中若干问题研究

改革开放以来，东莞市积极吸纳海外资本与技术，通过“三来一补”企业的快速发展，带动了非农产业和小城镇的迅速发展。然而，受我国分散的工业化和农村城市化政策体制的影响，在快速城市化过程中也暴露出很多值得关注的问题。该文基于实地考察与问卷访谈，重点分析了土地利用效率低、外来人口集中以及基础设施建设与城市经济发展不相协调等问题，并提出协调城市化发展的对策。     

基于农用地价格体系的征用地价应用研究

农用地价格体系和估价成果应用是当前农用地定级估价工作的难点和争论焦点，该文提出了农用地价格体系应以资源基准地价为基础，通过一系列修正，得出分级分区的征用基准地价、不转变用途的农地流转价、转变用途的农地转用价；以佛山市南海区的农用地估价成果为例，就其与现行征地补偿标准进行了比较，并与南海城区、广州市区城镇建设用地基准地价的相互衔接性进行了验算，应用成本逆推法，从城镇基准地价导出建设用地生地地价，在内涵一致的条件下相互比较。结果表明，按此地价体系建立的农用地征用价能够与城镇地价相衔接，可为城乡地价一体化的建立提供实证。     

基于卫星遥感的鲁西北季节性风沙化土地研究

文章对鲁西北地区季节性风沙化土地的分布、特征及近20年来的演变做了初步的分析，阐述了该地区风沙化土地的成因及其危害，在肯定已有治沙成绩的基础上，就如何合理利用和改造这些土地提出了合理布局农田林网、地一步完善农田水利设施等意见和建议。     

合肥市耕地和粮食可持续发展研究

收集1980～1999年合肥市耕地、人口、粮食等资料，定量分析在城市化快速发展下耕地的数量、质量变化和耕地减少的形式以及人口、粮食的变化，并用回归法分析它们的变化趋势。研究认为，在2005，2010年合肥市食物保障能力分别为97％和95％，对粮食生产与其影响因素进行了灰色关联分析，提出提高粮食产量的对策和实现途径。     

209国道许家湾滑坡的成因及治理对策

结合许家湾滑坡灾害点的地质背景资料和现场勘察结果，从滑坡区的地貌、区域地质构造、地层岩性、土壤特性、水文地质特征以及人类工程活动等方面分析滑坡成因机制。指出同向多层次结构的边坡类型、山高坡陡及地表水汇集走廊的地貌特征、发育多组密集节理的区域地质构造、软硬互层的地层岩性、土体的残余强度特性等是滑坡形成的内因；而人为削坡、强降雨和破坏植被营造水耕梯田等人类活动所造成的流水浸蚀，是滑坡形成的诱发空子。基于滑坡稳定性的定量计算，确定了采用抗滑挡土墙、格构式地梁和垫梁组成抗滑系统，并布置了由树枝笼渗沟构成的排水系统等工程治理措施。现场监测结果表明滑坡治理措施卓有成效。     

On the land use in Three Gorges Reservoir area

In this study the arable land changes in two counties (Zigui and Xingshan) in the Three Gorges Reservoir area in China are investigated. The statistical data from the officially published statistical books are used to study these changes in the two counties during the past 50 years since 1949. The changes of arable land, changes of arable land per capita, and changes of multiple crop index in Zigui and Xingshan counties are examined. Using an index method, we conclude that the two counties are critical in the sustainable utilization of arable land.     

Present land use and cover patterns and their development potential in North Ningxia

With the objectives to acquire the fundamental data of the territorial resource, understand the impacts of human activities on the land use and cover patterns and evaluate the potential of the future exploitation, an intensive land cover classification with an accuracy of 93% has been completed for North Ningxia by remote sensing technique based on the adoption of a combination method composed of texture training, maximum likelihood classification and post-processing such as re-allocation and aggregation. This classification result was incorporated with the contemporaneous socio-economic and meteorological data for cross-sectional regression modelling to reveal the spatial determinants of the land cover patterns and understand the human-environmental relationships. A tentative evaluation on the potential of soil exploitation in the near future was carried out in combination with our land use and cover change detection results aiming at supplying some useful references for the central and local governments in their sustainable land use planning.     

Statistic forecast of typhoons going over the Chinese coasts

According to the measured data of typhoons going over the Chinese coasts in 1949-2002, a statistic relative equation showing the relation between the central atmospheric pressure of typhoons in a certain region at a certain period of time and their accumulation of frequency is established, and the concept of recurrence interval of typhoons is put forward, which is of actual significance for typhoon disaster reduction along the coastal area.
