虚拟水下区域农业对水资源短缺的脆弱性研究

Research on the Vulnerability of Regional Agriculture to Water Shortages under the Perspective of Virtual Water

水资源是人类生存发展的重要战略资源,而农业是水资源密集型行业,受水资源条件的冲击最大,科学的评判农业对水资源短缺的脆弱性对农业安全问题至关重要。将农产品虚拟水净贸易量纳入指标体系,构建水资源投入产出流量表和核算模型,以江苏省为例,初步评价江苏省农业对缺水的脆弱性,并对降低脆弱性提出了相关建议。

Water resources has become the important strategic resources for human survival, at the same time, agriculture is a water intensive industry, which is impacted by the water resources conditions most. The scientific evaluation and detection of the vulnerability of agriculture to water shortages is crucial for agriculture safety. Based on the analysis of the factors affecting the vulnerability of agricultural to water shortages, this study chooses the indictors from two parts, namely sensibility and resilience. Also, the net virtual water trade volume of agricultural products is innovatively included in the indictors, the water input and output flow form and accounting model is established, and the vulnerability of agricultural water shortages in Jiangsu is analyzed. In the end, the advices to reduce the vulnerability of agricultural water shortages in Jiangsu are given.
