摘　　要：针对景观格局研究中景观指数粒度变化效应对研究结果的影响,筛选NP、PD等8个景观指数,采用景观指数分析法分析了1990~2010年黄河下游河道及河道外1~10km缓冲区的景观指数及景观格局时空动态变化,发现20年间虽然黄河下游主河道变化不大,但沿岸县市的水域面积发生了巨大变化,河道以外2km为土地利用变化的拐点,河道以外4km处为景观指数变化的拐点。This paper focused on the grain size effects of landscape indices variation in landscape pattern analysis.By selecting 8landscape index（NP,PD,etc）from 1990 to 2010,landscape index analysis method is used to analyze the spatial temporal dynamic variation of river channel on the downstream of the Yellow River and offstream buffer zone in the range of 1-10 km.We found that the water area of the coastal cities have undergone tremendous change although the main river changed little;2km offstream of the river was inflection point of the land use change while 4km offstream of the river was inflection point of the landscape metric change.
