东营市土地利用/覆被变化分析及驱动力研究

Study of Land Use/Cover Change and its Driving Forces in Dongying,Shandong Province

综合利用RS及GIS方法,以东营市1992、2000及2010年TM/ETM+遥感影像为基础,分析了东营市18年间土地利用时空演变的情况及驱动机制。结果表明:东营市土地利用/覆被变化在2000～2010年间最为显著,1992～2000年间变化不显著;滨海地区、内陆经济发达地区为土地利用变化发生的主要区域;监测期内,研究区景观要素类型相互转化较为频繁,主要表现为耕地转为建设用地,草地转为耕地,未利用地及滩涂转为盐田虾塘;人口、经济增长及城镇化是该区域土地利用/覆盖变化的主要驱动因子。

Based on the remote sensing images（TM /ETM＋） of land use in Dongying City in 1992,2000and 2010,this article analyses the spatial and temporal changes of land use in Dongying City and driving force in recent eighteen years by the methods of RS and GIS.The conclusions are as follows：（1） the maximum annual land use change in the Dongying has occurred in the period of 2000to 2010,the changes are not significant from 1992to 2000 ;（2） the most obvious changes are found at the coastal areas and the economic developed areas of inland ;（3） in the monitoring period,the mutual conversion among land use types is frequent,and the major patterns of 1and use changes are the conversions of cultivated land to construction land,grassland to cultivated land,unused land and beach land to salt pan and breed pond ;（4） the main forces of land use changes in the study area are population growth,economic development and the improvement of the level of urbanization.
