摘要
建立了区域矿产资源的因果关系模型、流量反馈模型及不同开发模式下的状态方程与轨迹 ,结果表明 ,状态轨迹不是自然衰减的指数曲线 ,也非常见的 S型曲线 ,而是具有幂函数曲线的特征 .但资源的替代方程及发展轨迹与自然界生物竞争具有相似性 ,是一条组合的准 Logistic曲线 .
A causality model and flux feedback model of regional mineral resources are established, and its state equations and loci are thereout founded in this paper. The results show that the pattern of its state loci is neither an index curve of naturally attenuate one nor a normal S one, but of some characteristics of a certain power function . Its substituting equations and loci, however, are similar to which of creatures rivalry in nature , viz, a combined simulated curve Logistic.
