Title    Rational use of renewable resources strategy
Abstract
Forests, fisheries, wildlife and  so on are  renewable resources,
over-exploitation can cause the depletion of resources, which cannot be
restored within a short period of time or even become extinct; If we do
not take advantage of these resources  efficiently,  which  is  a waste  in the
same way. How  can we  use  the  resources  reasonably  in order to not only make
full use of resources  but also  to maintain an  appropriate  level?  By  building
a dynamic mathematical model, then we can take reasonable measures to use 源自%六[维%论*文\$网.加7位QQ3249^114 www.lwfree.cn
the resources appropriately.
On the basis of mathematical analysis and mathematical models, this
passage makes a research on  renewable resources  of  biological class.
Through  yield mathematical model, mathematical model of efficiency,
over-exploitation of the mathematical model, optimal use of economic
analysis  model, we can  develop a reasonable optimal renewable resource use
strategies. Finally, by the example of the forest resources, we make use
of the above model to reach a conclusion.
