Abstract:
The integration between the biogeochemical cycles model of climate change
and the model of land-use change to nutrient loads in related to ecosystem
responsiveness which is suggests that coastal and marine ecosystems tend to be
influenced by land use changes, while for climate change is not too. Simulation results
show, nutriend loads as the main cause of increase in primary productivity rate
compared to sea surface temperature. But in another side, sea surface
temperature will be very vulnerable to suppress primary productivity rate, if
the temperature conditions are above normal conditions. The Java Sea primary
productivity level is very much influenced by the nutrient loads if the higher
human activity on land. While the effect of sea surface temperature changes not
bee too significant, otherwise the primary productivity increased can be
suppressed, if there is an increase in temperature. Thus the Java Sea can be regarded as
one of the waters and the sea in Indonesia whose primary productivity level is
strongly influenced by the activity of land land use change in Java, Sumatra
and Kalimantan, and if said to be vulnerable by the influence of climate change
impact is not very big impact to the decline in primary productivity rates due
to the dominance of nutrient loads loads from the mainland is very strong
compared to changes in ocean temperature from the climate around the Java Sea –
