Agro-water Resource System and Its State Evaluation Based on Information Entropy Theory

摘要：

The agro-water resource system may be divided into two subsystems,agro-water resource and mankinds farming activity.Original and secondary problems arises when two sub-systems can not develop in harmony.A given districts system condition may be expressed as taking degree of mankinds farming behavior extent to the key element of the agro-water resource.This paper proposes information entropy theory and deduces a theoretical evaluation method on a given agricultural areas water system state.Loess area of Shaanxi Province is the care study.Result coincides in the reality.
