Study on the suitability evaluation of drought prevention and control measures in the Hengyang-Shaoyang-Loudi arid corridor of Hunan Province
Based on engineering measures such as water storage and conservation in the Hengyang-Shaoyang-loudi region,as well as non-engineering drought resistance capabilities such as planting and regulation methods,and taking into account various factors such as the likelihood of drought and water scarcity,the duration of drought,and the severity of drought and water scarcity,a suitability evaluation technique for drought resistance measures in the Hengyang-Shaoyang-loudi arid corridor based on system risk analysis theory is adopted.From the perspective of economic,ecological and risk suitability,a study on the appropriateness evaluation of drought resistance and water conservation measures was carried out.A suitability evaluation system for drought prevention and control measures in the Hengyang-Shaoyang-loudi arid corridor was constructed.Taking into account the particularity of the Hengyang-Shaoyang-loudi arid corridor,a suitability evaluation was conducted on the existing engineering layout,industrial layout,and control measures,and suggestions for drought resistance and water conservation measures in the Hengyang-Shaoyang-loudi region were proposed.
