摘　　要：针对城市绿地面积增加而当前水资源日益短缺的情况,对高效的绿地灌溉方式的探究已迫在眉睫。据此,提出了一种绿地灌溉模糊控制系统,该系统是以充分利用气象预报来达到智能节水灌溉的。如果气象预报下雨则采用方案一,即以降雨量和土壤水势作为输入;如果不下雨则采用方案二,即以温度和土壤水势作为输入。两种方案均以绿地灌溉量为输出。选择好输入量后,用MATLAB仿真其模糊化、模糊推理和解模糊的过程,从而获得绿地灌溉量的输出曲面图,这对探究高效的灌溉方式具有重要意义。Aiming at the present conflict between increasing urban greenbeh area and shortage of water resources, the exploration of a high-efficient irrigation technique for greenbelt has been imminent. According to this situation, a fuzzy control system for greenbelt irrigation was put forward, which fully uses weather forecast information to realize the intelligent water-saving irrigation. If it will rain, the first scheme will be adopted, namely use the precipitation and soil humidity as input; if it won＇t rain, the second scheme will be adopted, namely use the temperature and soil humidity as input. Both of the schemes all use the greenbelt irrigation volume as output. After choosing the inputs, the process of their fuzzification, fuzzy reasoning and fuzzy solution was simulated by MATLAB, so as to obtain the output surface plot of the greenbelt irrigation volnme, which has significance for exploring high-efficient irrigation method.
