摘要
为建立实用、高效的水土流失防治责任范围变化预测模型,提高合规性判断的准确性,在总结水土流失防治责任范围可撤销性、时空交错性、临时性和条件适用性等4个主要动态特性的基础上,提出一种基于数字孪生的水土流失防治责任范围变化预测模型。数学模型为描述防治责任范围状态的虚拟模型,防治责任范围为物理实体,模型基于防治责任范围变化主要因素的孪生数据,对防治责任范围有效性状态进行评估和预测。结果表明:模型对防治责任范围变化进行预测的正确率提升约38%,具有良好的预测防治责任范围变化的性能,有助于进一步提升提高遥感监管成果的质量,在生产建设项目遥感监管应用领域有一定的借鉴意义。
In order to establish a practical and efficient prediction model of soil erosion control responsibility range change and improve the accuracy of compliance judgment,a model for predicting the change of soil erosion control responsibility range based on digital twin is proposed.The model is based on summarizing four dynamic characteristics of soil erosion control responsibility range,which are reconcilability,space-time interweaving,temporality,and conditional applicability.Taking the numerical model as a virtual model describing the state of the range of control responsibility,and the range of control responsibility as a physical entity,the model evaluates and predicts the eff ectiveness of the range of control responsibility,based on the twin data of main factors that change the range of control responsibility.The result shows that the model improves accuracy of predicting changes in the range of control responsibility by approximately 38%,which has good performance in predicting changes and can further improve the quality of remote sensing supervision results.It can provide a certain reference in the field of remote sensing supervision applications for production and construction projects.
