Abstract

Agricultural disasters frequently occur in China. Therefore, this article studied the prevention and control of drought and flood disasters in agricultural land and the optimization method of planting structures to avoid disaster. Firstly, the impact of the change of input structure on the prevention and control of drought and flood disasters on agricultural land was analyzed, and the evaluation system of input-output efficiency was constructed. Secondly, the evaluation model was built by DEA method, so as to provide the theoretical basis for the quantitative evaluation of input-output efficiency. Taking Jiangxi Province as an example, the input-output data of drought and flood control of agricultural land in twenty cities in 2014-2017 was analyzed. The results show that the input-output efficiency of 80% of farmland in Jiangxi Province is low, and the resources of drought and flood prevention are not sufficiently utilized. In addition, the low pure technical efficiency and scale efficiency are the main reasons for the low input-output efficiency of drought and flood prevention. The effect of human and financial input in drought and flood prevention of farmland in Jiangxi Province is slightly different for value output and actual output. From the aspects of strengthening the investment in basic facilities and the technical research and development of agricultural products, the optimization strategy for the input structure of drought and flood prevention of agricultural land is put forward.

农业用地旱涝灾害控制与种植结构优化防灾方法

农业灾害在中国频繁发生。因此，本文研究了农业用地旱涝灾害的防治和种植结构的优化方法，以避免灾害的发生。首先，分析了投入结构变化对农田旱涝灾害防控的影响，构建了投入产出效率评价体系。其次，采用DEA方法建立了投入产出效率的评价模型，为投入产出效率定量评价提供了理论依据。以江西省为例，分析了2014-2017年20个城市农田抗旱防汛投入产出数据。结果表明，江西省80%的农田投入产出效率较低，抗旱、防洪资源利用不足。此外，纯技术效率和规模效率较低是导致抗旱防汛投入产出效率较低的主要原因。江西省农田抗旱防汛人力和财力投入的价值产出与实际产出略有不同。从加强基础设施投资和农产品技术研发等方面，提出了农业用地抗旱防洪投入结构的优化策略。
