摘要
运用ERDAS和ArcGIS技术,以宁夏生态移民安置区——红寺堡镇为研究对象,基于1989,1999,2006,2010年的TM遥感影像数据,进行城镇土地利用变化研究.结果表明,从总体来看,随着人类活动不断增加,研究区的耕地和草地景观类型范围扩大,呈成片分布.同时,人类活动又对水体和未利用地景观进行不断分割,使研究区原来整体的自然景观呈斑分布.耕地转化为草地和建筑用地的面积呈上升趋势,1989—1999年,有84.13%的耕地转化为草地和建筑用地;1999—2006年,有97.10%的耕地转化为草地和建筑用地;2006—2010年,有85.96%的耕地转化为草地和建筑用地.
The article starts the investigation on urban land use change with ERDAS and ArcGis technique,by taking the Hongsibu District of Ningxia Ecological Immigrant Settlement as the object,and upon the TM remote sensing image datum in the years of 1989,1999,2006,and 2010.The results show that on the whole,the escalation of human activities makes the farmland and grass landscape type in research area larger that they distributed in pieces.In the meantime,the consistent human activities cut apart the water bodies and unutilized landscapes and make the original natural scenery inside the search zone spot distribution.The proportion of farmland transferred to grassland and building site is on the rise.84.13%of farmland was transferred to grassland and building site from 1989 to 1999,and 97.1% of them to grassland and building site from the year of 1999 to 2006.85.96% of farmland was transferred to grassland and building site through 2006 to 2010.
