Especially in recent score years , in autonomous and nonautonomous systems , the neutral , finite - delay , infinite - delay , diffusive , discrete , discrete - delay , generalized , difference and other style models were discussed on optimal harvesting , osillation , stability , global stability , and other asmptotic behaviors of logistic equation . reference were searched in [ l - 6 ] , [ 10 - 18 ] , [ 20 - 31 ] , [ 34 ] . the periodic and almost periodic function logistic equation , which are widely studied recently , the results about the above are found on many kinds of magazines 尤其是近二十多年来,在自治系统与非自治系统中有关有限时滞型,无限时滞型,中立型,离散型,扩散型,离散时滞型,广义型,差分型logistic方程的最优捕获策略,振动性,周期解,概周期解,渐近性态,全局性态等方向进行了各方面的研究,可参见文献[ 1 - 6 ] , [ 10 - 18 ] , [ 20 - 31 ] , [ 34 ]
