Ecological Engineering Model of Farmland Water Conservancy and Construction Benefit Evaluation
In order to further ensure national food security,this study focuses on optimizing high standard farmland water conservancy.Firstly,a field engineering layout model based on farmland size is proposed,and then a benefit evaluation model for farmland water conservancy engineering construction is designed.In the study two field irrigation and drainage systems are designed based on the size of the field,namely adjacent layout of irrigation and drainage systems and alternative layout of irrigation and drainage systems.The evaluation accuracy of the combined-empowerment projection tracing method is relatively high,with a maximum fit of 94.8%and a minimum error of only 11.3%,indicating a higher prudence and reliability in the evaluation.This method can reasonably analyze the construction benefits of farmland water conservancy projects,and the research presents practical significance in promoting the construction of high-quality farmland.
