摘要
在遥感技术和地理信息系统平台的支持下,以1980－2005年间的6期遥感影像为基础,经过矢量化后得出哈大齐工业走廊范围内的哈尔滨、大庆和齐齐哈尔市区的土地利用变化数据。结合三个城市的经济统计数据,建立土地利用动态变化模型,在此基础上引入两个驱动因子评价指标（驱动效率指数和经济效益指数）,对比分析三个城市的土地利用结构与经济发展的关系,对其土地利用结构进行合理性分析。研究表明：大庆市随着石油资源的耗竭,地区的经济产业结构做出相应调整,土地利用结构趋于相对稳定;哈尔滨在多元化的经济发展模式下,形成相对合理的土地利用结构,进而促使经济不断保持协调稳定发展;齐齐哈尔市驱动因子评价指数尚未趋于稳定,区域经济发展还在很大程度上依赖土地资源的消耗。本研究为进一步的土地评价和土地利用结构调整提供相应的基础和依据。
Supported by RS and GIS platform,the vectorial land use change data of Harbin,Daqing and Qiqihar,which were in the range of Ha-Da-Qi Industrial Corridor,were obtained on the basis of the remote sensing images covering 1980,1985,1990,1995,2000 and 2005.Based on economic statistical data of the three cities and the dynamic change model of land use,the land use change increment data of 2010 were predicted.Furthermore,two driving indicators（driving efficiency index and economic benefit index） were introduced to evaluate the land use change,and the relationships between land use structure and economic development in the three cities were compared.In addition,the rationality of the land use structure was analyzed.The results showed that,the land resources in Daqing damaged due to excessive exploitation of petroleum resources.At the same time,the exhaustion of oil resources led to the restriction on economic development in the city,especially from 1995 to 2005,thus the regional industries has been restructured correspondingly since 2005 in order to make the land resources and economic development in a relatively stable way.As for Harbin,the economic development was not dependent on the exploitation of land resources completely compared with Daqing city.In the major city,more factors such as government policies,foreign trade and high technology dominated its economic development.Different from the two cities analyzed above,the economic development of Qiqihar city tended to be dependent on land resources to a certain degree,hence resulting in the imbalance in the land use structure,which would inevitably affect the regional economic development in the future.So,this research provides a basis for further evaluation of land use and land use structure adjustment.
