【摘要】：随着市场经济的快速发展,土地交易市场不断壮大,土地估价对经济有序发展的重要性也日益突显。宗地评估是一项繁琐且专业性很强的业务,传统的土地估价工作存在着主观性强、效率低、信息处理能力差等缺点。且宗地本身具有明显的空间特征,相关数据具有明显的区域性和空间性,依靠落后的估价方式和信息管理手段的手工作业式估价,已难以满足日益繁重的业务需要。然而,越来越大众化的GIS,为解决此类问题提供了技术上的可能。因此,本文对建立基于GIS的宗地估价管理信息系统进行了深入探讨,以期通过GIS强大的空间数据及属性数据处理、分析、管理能力来解决目前估价业务中存在问题。本文在宗地估价信息系统理论研究的基础上,对基于GIS的宗地估价管理信息系统进行了定义,并构建了GIS支持下的宗地估价业务流程模型、估价方法自动化选择模型等专业估价模型。在此基础上,本文以组件式GIS技术、空间数据库技术、软件开发技术等系统开发技术,作为系统的技术支持,进行系统开发。本系统以Visual Studio2008为开发平台,以C#为编程语言；并采用SQL Server2005关系型数据库存储相关的空间数据与属性数据,建立了宗地估价空间数据库。本系统最主要的作用就是利用GIS手段辅助宗地估价,提高宗地估价的效率,提升估价结果的准确性及客观性。具体包括：利用GIS的数据采集和管理功能,组织和管理宗地估价过程中涉及到各类数据；利用其空间分析功能选取市场比较案例及测量空间地物距离；利用其空间查询功能,实现宗地属性数据和空间数据的查询及可视化表达。除辅助估价功能外,系统还具备历史估价项目、估价模型、市场比较案例、基准地价成果更新等管理功能,以便用户对不同类型、不同来源、不同时期的估价数据进行统一的管理,为估价工作提供的数据支持。经过以南京市某宗工业用地为例进行的系统实践证明,本系统能够规范宗地估价流程,实现宗地价格评估自动化及估价信息统一管理的功能。
[Abstract]:With the rapid development of market economy, the land market expansion, land valuation on the importance of the orderly development of economy are also increasingly prominent. Land evaluation is a complicated and highly professional service, the traditional land valuation are subjective, low efficiency, information processing ability and parcel itself has shortcomings. The spatial characteristics, regional and space related data has obvious, manually backward valuation methods and information management means the valuation has been difficult to meet the increasingly heavy business needs. However, more and more popular GIS, it provides technical possibility for solving this kind of problems. Therefore, this paper to establish the GIS evaluation management information system based on in-depth discussion by the powerful GIS spatial data and attribute data processing, analysis, management ability to solve the current valuation industry There are problems in business.
In this paper the land appraisal information system based on the theoretical research, the management information system based on the GIS valuation parcel is defined, and the construction of the GIS under the support of the evaluation model of the business process, automation and other professional valuation methods choice model evaluation model. On this basis, based on the component GIS technology, spatial database technology, software the development of technology and system development technology, the system as the technical support system is developed. This system uses Visual Studio2008 as development platform, using C# as the programming language; and the SQL Server2005 relational database storage number of spatial data and attribute data, established to estimate spatial database.
This system is the most important auxiliary evaluation by means of GIS, improve the efficiency of land appraisal, enhance the accuracy and objectivity of appraisal results. Including: the use of data acquisition and management function of GIS, the organization and management of the land appraisal process involves all types of data; analysis function to select the market comparison case and measuring spatial distance using the query space; using the functions of space, query and visualization of the spatial data and attribute data expression. In addition to estimate functions, the system also has the historical valuation, valuation model, market comparison case, the datum land price update management function, so that users of different types, different sources, valuation data in different periods the unified management, to provide data support for valuation work. After taking a industrial land as an example of Nanjing city system It is proved that the system can standardize the process of the estate appraisal and realize the function of the automation of the price assessment and the unified management of the information of the price.
