摘要:水资源的有限性和可再生的周期性决定了任何一个地区的水资源支撑的社会经济规模都有不可突破的阈值,也就是水资源的承载力是有上限的。现如今人类对于水资源的过度消耗和建立在环境、资源基础上的发展方式让许多城市、地区的发展都受到水资源因素的限制。而产业结构作为协调资源、环境和经济社会的重要纽带,其优化升级是提高水资源承载力的重要途径。在这种大背景下,探讨如何调整产业结构和发展模式,实现水资源的最优化配合,使水资源发挥最大的经济和生态价值的问题,具有重要的现实意义。本文归纳概括了水资源承载力及产业结构优化的研究背景及国内外研究现状,探讨了目前水资源承载力研究中存在的问题和未来的研究方向,指出产业结构和水资源承载力之间关系密切,相互联系,相互制约,对二者关系的定性定量分析和实际应用进行研究具有重要的现实意义。本文选取松花江流域为研究区,采用倒算法计算松花江流域及三个子流域的水资源可利用量,在可利用水量的基础上利用常规趋势法、面积定额法计算2030年流域各类需水量,最终得到流域的水资源可承载力的经济规模和人口。流域在2030年得出流域可承载的最大社会经济规模为73778亿元,可承载的人口上限为7266万人;以水资源承载力计算成果为参数条件,构建多目标优化模型,对流域2030年产业结构进行优化,对方案进行遴选,并对流域未来发展的总体布局及三次产业的发展重点提出了建议。

Abstract:The limited nature of water resources and the cyclical nature of renewability decide that the scale of social and economic support of water resources in any area has an impossible threshold, that is, the carrying capacity of water resources is upper bound. Nowadays, the excessive consumption of water resources and the way of development based on environment and resources make the development of many cities and regions restricted by water resources. As an important link of resource, environment and economic society, the optimization and upgrading of industrial structure is an important way to improve the carrying capacity of water resources. Under this background, it is of great practical significance to discuss how to adjust the industrial structure and development mode, achieve the best coordination of water resources and make the water resources play the biggest economic and ecological value. This paper summarized the research background and research status of force and industrial structure optimization of water resources carrying, discusses the current research on water resources carrying capacity in the existing problems and future research direction, pointed out that the industrial structure and the close relationship between the water resources carrying capacity, mutual connection, mutual restraint, has important practical significance to study on qualitative and quantitative analysis and practical application of the relationship between the two. This paper selects the Songhua River basin as the study area, using Daosuan method to calculate the Songhua River basin and three sub basins of the available water resources in the basin can be calculated in 2030, all kinds of water demand by water on the basis of using the conventional trend method, quota area method, finally get the bearing capacity of river basin water resources economic scale and population. The largest scale of social economy in 2030 that river basin can be carrying 73778 billion yuan, the population limit carrying 72 million 660 thousand people; the water resources carrying capacity calculation results for the parameters, construct a multi-objective optimization model, to optimize the structure of industry in 2030, the scheme selection, and puts forward some suggestions on the overall development of key the layout of the future development of the basin and the three industries.
