摘要:

物质循环是人类获取资源的重要方式,尤其是对于磷这种地球生物生存不可或缺、不可替代的资源,理解其循环过程对资源可持续利用乃至人类永续发展具有重要意义。目前关于物质循环的研究多采用物质流分析方法,该方法是一种以物质流动过程质量守恒为基础、以系统分析为手段的定量核算方法,需要将系统物质流动路径与核算模型融为一体。为了解决传统物质流分析方法中数据与模型无法分离从而不适应与复杂物质循环过程模拟的问题,本文提出了复杂物质循环过程模拟概念模型与定量计算公式,建立了基于数据库、模型库、结果库、分析库4库分离的复杂物质循环过程建模方法,并基于EnVirLab环境虚拟仿真实验平台,以中国1600—2012年畜禽养殖系统磷循环过程为例开展方法验证研究,验证了基于4“库”分离的复杂物质循环过程模拟分析方法的可行性。本文对于建立标准化的物质流分析方法及开发复杂物质循环过程模拟软件,进而精确量化物质循环路径,对实现物质循环过程模拟从定量格局描述性分析向定量机理解释性分析转变具有重要意义。

Abstract:

Material cycling is an important way for human beings to obtain resources, especially for phosphorus, an indispensable and irreplaceable resource for life on the Earth, and it is of great significance to understand phosphorus cycling process for the sustainable use of resources and sustainable development of human society. At present, the research on material cycle uses the material flow analysis method, which is a quantitative accounting method based on the quality conservation of the material flow process and by means of systematic analysis, integrating the system flow path with the accounting model. In order to solve the problem that the data and model in the traditional material flow analysis method cannot be separated, which is not suitable for the simulation of complex material cycling processes, this study proposed the conceptual model and quantitative calculation formula of complex material cycle process simulation, and established the complex material cycling process modeling method based on database, model library, result library, and analysis library separation. Based on the environment virtual laboratory (EnVirLab) platform and taking the phosphorus cycling process of livestock and poultry breeding system in China from 1600 to 2012 as an example, a method validation study was carried out, and the feasibility of complex material cycling process simulation and analysis based on four library separation was verified. This study is of significance for establishing standardized material flow analysis methods and developing complex material cycling process simulation software, quantifying the material cycling path accurately, and realizing the transformation of material cycling process simulation from descriptive quantitative pattern analysis to explanatory quantitative mechanism analysis.
