| 中文摘要: |
| 根据实时调度原理及农业水资源配置特点，建立了分层耦合的水资源实时优化调度模型，该模型包括供需水中长期预测、中长期优化配置、供需水实时预报、短期渠系配水和基于模糊识别的实时修正5个模块，应用该模型可实现对预报、决策、实施、修正的滚动向前调度。在中长期优化调度模块中提出了利用模糊聚类和马尔科夫时间序列的预测方法对有效降水量进行预测，并根据预测的年型计算作物需水量和地下水可开采量。实例计算表明，应用该模型实行的实时优化调度与各种供水已知情况下的理想最优调度方案偏差较小。 |
| 英文摘要: |
| Based on real time dispatch principle and according to the characteristics of deployment for agricultural water resources, a layered coupling model for optimal dispatch of water resources is established. The model consists of five modules: long term water demand and supply forecasting module, mid and long term water resources optimal deployment module, module for real time forecasting of water demand and supply, module for short term dynamic water distribution of irrigation cannel system and the module for real time error correction based on fuzzy identification. By applying this model the forward rolling dispatch including the forecasting, decision making, implementation and error correction is realized. In the mid and long term water resources optimal deployment module a method based on fuzzy clustering and Markov chain for forecasting of the available
precipitation is introduced, and the crop water demand and permissible exploited amount of groundwater can be predicted according to the forecasting. The application shows that the model can effectively reduce the error of optimal dispatch. |
