根据甘肃东部旱作区14个测站1989~1992年0~2m土壤水分实测资料,从大气降水-土壤水循环系统出发,探讨了旱作区不同气候类型土壤水库的贮水能力及其运行规律,给出不同农业干旱程度的贮水标准和贮水量亏缺额,为土壤水库潜力的开发利用提供了依据.

A new forecast method of the field soil moisture in dry season is built based on the artificial neural networks of the backlpropagation model. The results showed that the forecast accuracy is high enough as compared with the measured values. In general,this method is suitable for routine forecast of the soil moisture in computator condition of IBM PC / 386. This new method can be used to study the rational utilization of the soil moisture resources and to decrease the waste of agrometerogic resources of the...

A new forecast method of the field soil moisture in dry season is built based on the artificial neural networks of the backlpropagation model. The results showed that the forecast accuracy is high enough as compared with the measured values. In general,this method is suitable for routine forecast of the soil moisture in computator condition of IBM PC / 386. This new method can be used to study the rational utilization of the soil moisture resources and to decrease the waste of agrometerogic resources of the light and heat for the dry farming regions and dry season in China.It is likely to be a new approach to use valuable. observational data of soil moisture.

基于多层误差反传网络结构模型和一维时间序列拓展的方法,发展了一种新的旱季农田土壤湿度预报模式。该模式不仅预报准确性高,而且不受中期降水预报准确性的影响。一般只要具备386以上的计算机条件即可进行工作,十分便于业务预报推广。可为我国干旱地区或季节的农业区土壤水资源的合理利用和防旱抗旱,减少光、热农业气候资源的浪费提供有效的新方法。同时也为充分利用宝贵的土壤湿度观测资料开劈了途径。
