摘要: |
将熵的概念引入水资源系统中,构造了水资源利用结构特征的信息熵和均衡度定量计算公式,用其来表征水资源开发利用的合理性,结合熵变理论给出了水资源系统结构演化的判别标准,并在渭河流域关中地区进行应用。使用结果表明:渭河流域水资源开发利用结构正向着更加合理、均衡的方向演化。该结果表明信息熵能为人类水资源利用规划调控提供依据。 |

Study on the evolution of water resource structure based on information entropy |
|
Abstract: |
Concept of entropy is introduced into water resource system,expressions of information entropy and balance degree are given,which can be used to distinguish the rationality of water resource utilization system.On the basis of entropy variation theory,a method is produced to distinguish evolution pattern of water resource utilization system,and it can be used in Guanzhong area in Weihe River basin.Results manifest that water resources utilization in Weihe River basin is becoming more and more reasonable.Entropy provides reference for human to regulate water resource utilization. |
