一、建模依据与模型功能 建模依据的原则主要有:1.广泛吸收以往的研究成果,特别是有关水资源综合性研究的新成果。2.密切结合省情实际,从全社会角度研究水资源与国民经济发展之间的种种联系和影响。诸如水资源对社会经济发展、产业结构调整、国民收入、人民生活等的制约和影响。3.简单、实用。模型中涉及的变量和参数不一定很多,但要结构严谨、反应灵敏,便于调整参数进行模拟运算。 模型的主要功能是:1.研究在实现计划期(《七五》时期、《八五》时期,以至2000年)国民经济发展目标的前提下,全省水资源的供求关系和解决水资源问题的途径、方法,以及全社会的承受能力。
First, the basis for modeling and modeling The main principles of modeling are: 1. Widely absorb the previous research results, especially the new results on the comprehensive study of water resources. 2. In close connection with the actual conditions in the province, from the perspective of the whole society to study the water resources and the development of national economy, the various links and influence. Such as water resources on social and economic development, industrial restructuring, national income, people’s lives and other constraints and influence. Simple and practical Variables and parameters involved in the model are not necessarily a lot, but to rigorous structure, responsive, easy to adjust parameters for simulation. The main functions of the model are as follows: 1. To study the relationship between the supply and demand of water resources in the province and the solution of water resources problems under the premise of realizing the goal of national economic development during the planned period (“the Seventh Five-Year Plan” period, “the Eighth Five-Year Plan” period up to 2000) Ways, methods, and the affordability of the whole society.
