摘要:Pekalongan is one of several cities that lies in the Northern coast of Java island which is oftenflooded due to sea level rise. This condition impacted its urban development characteristic and increase in thefuture. In this research, both geographical information system based and spatial metric approach are used. Thespatial pattern is analyzed by using spatial metric based on the exploration of land use change that occurred.In this research, the spatial pattern is focused on aggregation pattern and diversity in coastal area. The resultshows that the land use of coastal area is dominated with swamp, then followed by settlement and fishpond.It is also shown that the greatest land use change occurred on paddy field and swamp areas. Based on thespatial metric calculation, the aggregation level of land use decrease periodically and has a small growth level.It is indicated from its metric value aggregation and diversity from two periods: 2003-2009 and 2009-2016.Overall, the land use of Pekalongan experienced large dynamics, especially in its coastal area. The spatialpattern trend in those area tend to be more sprawl as defined by the decrease of aggregation pattern and lowlevel of land use growth pattern.
