For the same amount of marine fishery resources , the more the prizing intensity , the more the increasing rate requested 在相同的资源生物量下,渔业资源的捕捞强度越大,所要求的资源生物量增长率就要越大。
The result shows that the biologic amount of marine fishery resources increase positively with increasing rate and negatively with fishing intensity 研究结果表明:海洋渔业资源生物量与其增长率成正相关关系,与捕捞强度成负相关关系。
A nonlinear dynamic model is built to study the relationship between the biologic amount of marine fishery resources and the increasing rate and fishing intensity 本文运用非线性理论建立了海洋渔业资源二次非线性捕捞的动力模式,研究了渔业资源生物量(资源量)增长与增长率和捕捞强度的关系。
To insure the sustainable development and harvest , we must control the fishing intensity at a certain level , and adopt logical strategy of fishing by doing this we can get the maximum sustaining yield , the marine fishery resources can not be utilized unduly and dry up 为了保证海洋渔业资源的可持续利用,必须把捕捞强度控制在一定的水平上,采用合理的捕捞策略,我们才可以得到持续的最大产量,才能避免海洋渔业资源的过度利用、枯竭。
