基于地理国情普查成果的城乡用地现状数据生产方法研究

Study on the Production Method of Urban and Rural Land Status Data Based on National Geographic Condition Survey Data

通过对地理国情普查成果数据、基础地理信息数据、城乡用地数据各自的分类指标体系进行分析研究,得到上述各类数据之间的相互关系。以此为理论基础,将地理国情普查成果作为数据基础,结合基础地理信息数据,对城乡用地现状进行调查。以嘉兴市本级为试验区,采用上述方法对嘉兴市城乡用地现状进行调查,最终得到嘉兴市本级968km^2内的城乡用地现状数据成果。通过上述方法,不仅能快速、科学地进行大范围城乡用地调查,同时能实现数据的更新监测。综上,本研究的内容为城乡用地现状调查探索了新方法,也为地理国情普查成果的应用提供了新方向。

Base on the analyzed classification index system of national geographic condition survey data,basic geographic information data and urban and rural land data,the interrelationship among the above types of data has been obtained.Based on this,the results of national geographic condition survey used as the data base,and the basic geographic information data are used to investigate the present situation of urban and rural land.Taking the current situation of Jiaxing city as the experimental area,the current situation of urban and rural land use in Jiaxing city is investigated by the above method.Finally,the data of urban and rural land in 968 km2 of Jiaxing city are obtained.Through the above method,people not only can quickly and scientifically carry out a wide range of urban and rural land survey,and can achieve the data update monitoring.This research not only explores the new method for the survey of urban and rural land use,but also provides a new direction for the application of geographic condition survey data.
