摘要
利用1988年、1997年TM影像和2002年SPOT影像,分析了郑州市郊区14年间土地利用动态变化情况,结果表明该段时间内郑州市郊区土地利用变化状况巨大,主要表现在耕地的减少以及城市及交通用地和居民点及工矿用地的增加,阐明了区域土地利用变化的特点,揭示了经济高速发展地区土地利用/土地覆被变化的时空过程及区域土地利用变化的空间分异规律。
Dynamic change in land utilization in the suburb of Zhengzhou in 1988, 1997 and 2002 are studied with the aid of remote sensing and GIS techniques. The results show that great changes of land utilization took place in research district.
