Abstract:

Ten indicators and grey correlation analysis method were adopted with the worst value of the indicators system as the reference to analyze the vulnerability of agricultural drought by the statistical and meteorological data of 2005 and 2015 in Henan Province, for the purpose to reduce the drought losses. The results showed that the drought vulnerability of Jiyuan, Sanmenxia, Luoyang, Kaifeng, Luohe and Hebi were relatively strong in Henan Province, while that of Shangqiu, Zhumadian, Xinyang, Xinxiang and Nanyang were relatively weak, and that of other areas were moderate. The drought vulnerability in Henan Province presented an obviously increasing trend from 2005 to 2015. In conclusion, as the core area of grain production in China, Henan Province should reduce its drought vulnerability and ensure food security by relying on science and technology innovation to develop water conservative and recycling agriculture, protecting water resources and increasing agricultural input.

Key words: agricultural drought, vulnerability, grey correlation, information entropy, weight, analysis, water conservative agriculture, recycling agriculture
