鬼城指数遥感监测系统的设计与实现

The Design and Realization of Ghost city index Monitoring System by Remote Sensing

随着城市的发展,房产的不合理开发,导致住房的空置率高、入住率低的空城或鬼城现象。传统方式监测鬼城耗时耗力,工作量较大。该研究利用地理信息系统和遥感技术,基于夜间DMSP/OLS灯光数据和Landsat TM数据,提出一种宏观监测方法,并以C#为开发环境,采用ENVI/IDL和ArcGIS Engine的二次开发手段,并结合混合编程方式开发鬼城指数遥感监测系统。系统对城区的建筑面积进行提取,进而与城区的人口数量进行拟合,根据住建部规定的占地用地标准确定各个区域的＂鬼城指数＂。同时提供鬼城指数专题图制作模块,为城区的合理规划和利用提供参考。

With the development of the city,the irrational development of the property leads to the vacancy rate of the housing and the low occupancy rate of empty city or ghost city phenomenon.The traditional way of monitoring it is time-consuming and energy-consuming and needs to do lots of work.This study uses the technology of GIS and Remote Sensing and utilizes the data of DMSP and Landsat TM,which presents a visible way of Monitoring ghost city that bases on mixed programming of ENVI/IDL,ArcGIS Engine and C#.The system extracts the area of city building and matches with the population of city and further gain the Ghost city index compared with the covers an area of the standard provided by Ministry of housing and housing.At the same time,the system provides the model of making thematic map,which gives help on the plan and use of the city.
