Grasslands with high yield have a large percentage of grass as the main component and a low percentage of weeds and bare land. Especially, Broad−Leaved Bock (Rumex obtusifolius.L) has high seed productivity and regeneration ability and is recognized as a highly harmful weed. In order to control the amount, it is necessary to grasp the growing point. In this study, we clarified changes in spatial dependence by examining the spatial modeling by using the time-series distribution survey data from 2015 to 2018.
