我把C题写好了，大家看下，
1.3 calculate the numbers of each species.Bolinao Coral Reef Ecosystem Model consist of physical exchange, ecological processes, the individual growth of aquaculture species, the change of each species, without considering activities of human culture. Model forcing factors are solar light, water temperature, dissolved organic carbon(DOC), total dissolved nitrogen(TDN), the amount of phytoplankton(Chl a), particulate organic carbon(POC), particulate total nitrogen(PTN). Suppose the model space is zero-dimensional, that equals ecological factors are distributed uniformly among ecosystem model space. Simulate the exchange between sites(site A, site B, site C, site D) and South China Sea, as well as the change in seawater quality.^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 没我写得好。。。 diao!!!!!!!!!!!!!!!!!!! 排泄物怎么算的……数据都没给全……能指导一下么……？
