Analysis of the correlation between disaster reduction engineering and output of agricultural production

To verify the impact of disaster reduction engineering on the agricultural output,we use the grey relational analysis algorithm and the measurement model to standardize many indicators in the agricultural production system,such as waterlogging control,irrigating,embankment and reservoir,and forming the assessment of the degree of the indicator association.At the same time,on the basis of the Cobb-Douglas production function,each indicator is included in the regression analysis,and the quantitative evaluation of waterlogging control and other indicators which affect the output of the agricultural production are completed.The empirical study has shown that the impact of the agricultural disaster reduction engineering on the agricultural production can be arranged from largest to smallest as waterlogging area,irrigating area,embankment length,salinization of arable land improvement area,reservoir capacity,and soil erosion control area;expanding the waterlogging control area,building the reservoir and increasing the length of the embankment can increase the total value of the agricultural output,and the waterlogging control has the greatest utility to increase agricultural output in these measures.The natural disaster hinders the development of agricultural production.And increasing the input of the disaster reduction engineering can be conducive to increase the output of agricultural production.
