【摘要】：河北省極度缺水的問題將威脅它作為中國(guó)糧食生產(chǎn)省份之一。為了分析河北省水資源稀缺的情況,筆者計(jì)算了該省2009年至2013年的玉米、稻米和麥子的虛擬水貿(mào)易(進(jìn)口/出口)。此外,筆者將審查河北省玉米、稻米和麥子國(guó)內(nèi)進(jìn)出口兩來分析每種谷物貿(mào)易的年度水儲(chǔ)蓄和損失。河北省2009年至2013年玉米、稻米和麥子的虛擬水計(jì)算結(jié)果現(xiàn)實(shí)這三種谷物每年進(jìn)出口量導(dǎo)致虛擬水資源的凈損失等于25,140,987,784立方米。作為水資源占用量的指標(biāo),河北省5年期間內(nèi)的谷物虛擬水貿(mào)易表明省內(nèi)玉米和麥子每年生產(chǎn)盈余增長(zhǎng)導(dǎo)致河北省農(nóng)業(yè)里的一個(gè)不可持續(xù)的水資源占用量趨勢(shì)。鑒于河北省的水短缺多年來惡化了,虛擬水貿(mào)易的應(yīng)用可以提供給河北省缺水森體一個(gè)可持續(xù)的解決方案,就是重組省內(nèi)農(nóng)業(yè)生產(chǎn)結(jié)構(gòu)更適合當(dāng)?shù)厮Y源稟賦。雖然,虛擬水概念尚未在中國(guó)水安全策略被接受,筆者認(rèn)為虛擬水貿(mào)易在未來的水資源管理策略起重要作用。
[Abstract]:The extreme shortage of water in Hebei will threaten it as one of China's grain-producing provinces.In order to analyze the scarcity of water resources in Hebei Province, the authors calculated the virtual water trade (import / export) of maize, rice and wheat from 2009 to 2013 in Hebei Province.In addition, the author will examine the domestic import and export of corn, rice and wheat in Hebei Province to analyze the annual water savings and losses of each grain trade.Virtual Water calculation for Maize, Rice and Wheat from 2009 to 2013 in Hebei Province, the net loss of virtual water resources caused by these three grains per year was 25140987784 cubic meters.As an indicator of water resource consumption, the grain virtual water trade in Hebei Province during the past five years indicates that the annual surplus of corn and wheat production in Hebei Province leads to an unsustainable trend of water consumption in agriculture in Hebei Province.In view of the deterioration of water shortage in Hebei Province for many years, the application of virtual water trade can provide a sustainable solution to water shortage in Hebei Province, which is to reorganize the agricultural production structure of Hebei Province more suitable for local water resources endowment.Although the concept of virtual water has not been accepted in China, the author thinks that virtual water trade plays an important role in the future water resources management strategy.
