摘要

基于1998

2002和2008年3期TM/ETM

和SPOT融合影像的目视判读分类结果

运用GIS空间分析技术和统计分析方法

分析了郑州市1998—2008年土地利用变化的时空特征及其驱动因素。结果表明:(1)10a间非农用地增加迅速

其中城市建设用地增加124%

工矿仓储用地增加158%;耕地面积减少40%

主要转向城市建设用地、工矿仓储用地和园地。(2)1998—2002年林地、菜地和园地等农业用地变化速度较快;2002—2008年工矿仓储用地、城市建设用地等非农用地变化速度较快。(3)经济发展和工业化速度较快的行政区

土地利用变化速度也较快。(4)交通网络的发展、人口与经济总量的增加是推动郑州市土地利用变化的主要因素

而产业结构的调整和升级推动了城市土地的集约利用。

Abstract

The spatial and temporal characteristics of land use change and its driving factors in Zhengzhou City in 1998-2008were analyzed based on visual interpretation results of three TM/ETM+ and SPOT fused images in 1998

2002and 2008

Spatial analysis module in ArcGIS software and statistical analysis.Results showed that:(1)Non-agricultural land increased rapidly over the past 10years

characterized by increases of 124% and 158%in the construction land and industrial storage land

respectively

while farmland was reduced by 40%due to the conversion to construction land

industrial storage land and garden.(2)In 1998-2002

agricultural land

including woodland

vegetable land and garden

changed more quickly;but in 2002-2008

non-agricultural land

including construction land and industrial storage land

changed more quickly.(3)The districts with more rapid economic development and industrialization showed a quicker land use change.(4)The land use change and expansion of urban area were mainly affected by the development of traffic network and the growth of population and economy

while the intensive use of urban land was promoted by the adjustment and upgrading of industry structure.
