【摘要】：农村空心化发展和大量"空心村"的涌现,严重地影响了我国新农村建设与发展进程。目前国内对区域性信息化数据库的研究主要体现在"数字城市"或"数字村庄"等单一地类要素的层面,对于同时拥有城市建筑特征和村庄地形特征的城镇近郊区所做的研究则相对比较缺乏。在分析城镇近郊区村庄空心化问题的过程中,反映此类村庄基本信息的数据库系统尚有待进一步研讨及合理地构建。本文基于无人机技术快速采集城镇近郊区土地利用信息,初步构建了城镇近郊区空心化村庄数据库系统,并进行了功能测试和实际应用,能够为村庄基础数据管理、村庄科学治理及建设发展提供一定的技术保障。本文的主要研究工作及成果如下:(1)收集和整理了实验区无人机影像、包括数字线划地图、土地利用现状图、经济社会调查数据等城镇近郊区空心化村庄分析所需的基础数据,并进行了数据入库处理及初步统计分析。(2)设计了城镇近郊区空心化村庄数据库系统模型结构,使用SQL Server储存属性数据及表格数据,使用ArcSDE空间数据引擎管理储存影像、栅格、矢量等空间数据。(3)使用C#语言,基于ArcObjects编程组件,编制了数据库系统相关功能模块及界面,实现了管理员对数据库中基础数据的管理、更新和保护等功能,以及用户对数据的浏览、查询和输出等功能,为空心化村庄治理工作提供基础数据支持。(4)该数据库系统中能够提供有关检索、统计和分析等模块,用于进行基础数据的统计分析,输出用户感兴趣的柱状图、折线图、饼图等统计图。并且,能够根据用户需要,输出村庄用地图斑与无人机影像的叠加图、基于生态敏感性分析的空心化整治潜力图等专题图,有助于科学、合理地推进城镇近郊区空心化村庄整治工作。
[Abstract]:The development of rural hollowness and the emergence of a large number of "hollow villages" have seriously affected the construction and development of new rural areas in China. At present, the domestic research on the regional information database is mainly reflected in the level of single ground elements such as "digital city" or "digital village". The research on the suburbs of cities and towns with both urban architectural features and village terrain features is relatively scarce. In the process of analyzing the hollowing of villages in the suburbs of cities and towns, the database system reflecting the basic information of this kind of villages needs to be further studied and rationally constructed. Based on the technology of UAV to collect the information of land use in the suburbs of cities and towns, the database system of hollowed villages in the suburbs of cities and towns is constructed, and the function test and practical application are carried out, which can manage the basic data of the villages. Village scientific governance and construction and development to provide certain technical support. The main research work and results of this paper are as follows: (1) the basic data needed for the analysis of hollow villages in the suburbs of towns and cities are collected and collated, including digital line map, land use status map, economic and social survey data, and so on. The model structure of hollowed village database system in the suburbs of cities and towns is designed. The attribute data and table data are stored by SQL Server, and the images are managed and stored by ArcSDE spatial data engine. Using C # language and based on ArcObjects programming component, the related function modules and interfaces of database system are compiled, and the administrator's functions of managing, updating and protecting the basic data in the database are realized. As well as the functions of browsing, querying and outputting the data, providing basic data support for the hollowing village governance.) the database system can provide relevant modules such as retrieval, statistics and analysis, etc. Used for statistical analysis of basic data, output histogram, broken line diagram, pie chart and so on. Moreover, according to the needs of users, we can output the superposition map of village land use map and UAV image, and the hollowed remediation potential map based on ecological sensitivity analysis, which is helpful to science. We will reasonably promote the renovation of empty villages near the suburbs of cities and towns.
