摘　　要：宏观物流是指在国民经济领域中发生在生产企业纯工艺生产前后以及商品流通过程中的物流活动。选取运输、储存、包装、装卸搬运、配送、流通加工和信息处理为宏观物流要素,并提出基于点集的Lebesgue测度定义的各个宏观物流要素的测度。鉴于宏观物流要素之间联系的错综复杂性与动态性,提出宏观物流结构的定性描述模型即多齿轮相互啮合模型和定量描述模型即一阶微分方程组模型,结合时间序列的谱分析,我们发现宏观物流要素测度的发展呈现周期性。A definition of macro_MF is given. Transportation, inventory, distribution, packaging, load and unload, distribution processing and information handling are selected as the macro_MF elements. The measure of different macro_MF elements based on Lebesgue Measure is brought forward for the first time, which will generalize the indices of macro_MF to a certain extent. Since the relations among macro_MF elements are complicated, we put forward a qualitative model of describing the macro_MF structure. One_order differential equations are founded to characterize the dynamic characteristics of the relations among macro-MF elements. It's concluded by spectral analysis of time series that the measures of macro-MF elements have the periodic developing tracks.
