There had been studies relating the effect of environment parameters to mangrove development and effect of mangrove abundance to environment parameters. But, the dynamic linkage of mangrove structure and environment parameters had never been revealed. This research aimed to study the dynamic vice versa linkage of mangrove structure of Rhizophora mucronata and the environment parameters in Semarang and Demak coastal area. Research was conducted through field observation and laboratory analysis. Observation was conducted through transect plotted in Semarang and Demak region where 4 observation station was occupied with 3 transect on each station. Dynamic linkage was analyzed through modeling occupied Powersim as the analysis tool. The result showed there were vice versa linkage of mangrove structure and environment parameters. The effect of environment parameters to mangrove dynamic including to growth rate and mortality rate of mangrove sapling and seedling, and reproduction rate of mangrove tree. While the effect of mangrove structure on environment parameters including temperature, TSS, salinity, pH, DO, organic matter, soil N, soil P, dissolved N, dissolved P and dissolved K. The development of dynamic model was also consider the effect of mangrove abundance which create limit on mangrove growth and reduce the reproduction rate and growth rate of mangrove. Further study concerning dynamic model of mangrove
