Abstract:
By ca lcu la ting and simu la ting, it is found: ( 1) TheM ax imum SustainableY ie ld (MSY) of the linear grow th population is dependent on the indiv idualw e ight. ( 2) W henB≤ 0.001 (B = A /K, hereK is the ca rry ing capac ity, and A is the param ete r of A llee effec t), the linear grow th population w ith A llee effec ts have hard ly been influenced by A llee effects. ( 3) TheM SY of the linear grow th popu la tion g rows w ith the increase o f net production rate firstly, and then decreases. At them eantim e, theM SY grow s w ith the inc rease o f the value o fB. M oreover, w hen the shape param ete rs of the sy stem are in the range from 0.3 to 2, M SY increases w ith the increase of them.
