【摘要】：辽宁省为我国东三省最为靠南的省份,是国家重工业基地之一。近年来,辽宁省依靠稳定的发展,为我国的经济增长做出了伟大的贡献。然而,由于省内水资源时空分布不均、人口压力增大等一系列原因,使得全省面临着极大的水资源挑战。如何保证辽宁省的水资源安全以及粮食安全,是维持该省经济和生态的可持续发展的重要战略问题。虚拟水是上世纪90年代被提出的用以解决水安全的新概念。这一概念自从被提出以来,就得到了广泛的研究与认可。它把人们依靠机器或工程的传统节水手段,提升为贸易等经济学的方法来解决水资源短缺问题,即贫水地区或国家通过从富水地区或国家进口水资源密集型产品,来节约本地区或国家的水资源,最终解决水资源短缺和粮食安全问题。现今,这种方法已经成为了提高水资源利用率,保障缺水地区水安全的有效手段之一。本文主要以虚拟水和虚拟水贸易的基础理论为出发点,利用联合国粮农组织推荐的CROPWAT软件,结合实际天气气候及降水等数据,计算了辽宁省主要农作物的虚拟水含量及贸易量,分析了辽宁省现今的农作物虚拟水贸易结构。通过研究发现,辽宁省为虚拟水净进口省份,比较符合缺水地区虚拟水贸易战略。然而,该省过于依赖大豆的进口,导致虚拟水贸易结构过于单一,不利于经济和生态的可持续发展。最终根据得出的结论提出了发展辽宁省虚拟水贸易的相关建议。
[Abstract]:Liaoning Province is the southernmost province of our country and one of the national heavy industrial bases. In recent years, Liaoning Province has made great contribution to the economic growth of our country by its stable development. Due to a series of reasons, such as uneven distribution of water resources in the province and increasing population pressure, the province is faced with a great challenge of water resources. How to ensure the safety of water resources and food security in Liaoning Province. Virtual water is a new concept proposed in -10s to solve the problem of water security. This concept has been put forward since it was put forward. It has been widely studied and recognized. It promotes people to trade and other economic methods to solve the problem of water shortage by relying on the traditional water-saving means of machinery or engineering. That is, poor water areas or countries by importing water-intensive products from water-rich areas or countries to save water resources in this region or country, and finally solve the water shortage and food security problems. This method has become one of the effective means to improve the utilization rate of water resources and ensure the water security in water shortage areas. This paper mainly takes the basic theory of virtual water and virtual water trade as the starting point. The virtual water content and trade volume of main crops in Liaoning Province were calculated by using the CROPWAT software recommended by FAO and the actual weather climate and precipitation data. This paper analyzes the trade structure of crop virtual water in Liaoning Province. It is found that Liaoning Province is a net import province of virtual water, which is more in line with the virtual water trade strategy in water shortage areas. The province is too dependent on soybean imports, which leads to a single structure of virtual water trade, which is not conducive to the sustainable development of economy and ecology. Finally, some suggestions for developing virtual water trade in Liaoning Province are put forward according to the conclusion reached.
