摘　　要：以花粉算法为基础,采用立方映射产生的混沌序列,模拟花粉配子初始化提高算法的全局搜索能力,加入单纯形算法提高计算精度,建立改进的花粉算法。分别采用基本花粉算法和改进的花粉算法,分析直线供水边界含水层抽水试验数据,确定含水层参数。就种群规模和待估参数初值范围等因素对算法收敛性的影响,进行了数值实验。结果表明,改进的花粉算法能够有效地应用于求解分析抽水试验数据,确定含水层的计算问题;种群规模越大,算法精度越高,但耗时太长;待估参数的取值范围对收敛性有一定的影响,范围较小收敛性更好。较基本的花粉算法,改进的花粉算法具有搜索能力强,计算精度高,收敛速度快等优点。Based on the flower pollination algorithm, the chaotic sequence generated by cubic mapping is used to simulate the initialization of generation of pollen to improve the global search ability of the algo- rithm. The simplex algorithm is joined to improve the calculation accuracy. The improved pollen algorithm is established. The basic pollen algorithm and improved pollen algorithm are used to analyze the pumping test data of aquifer water of straight line recharge boundary. The aquifer parameters are determined. Aiming at the influence to the convergrnce value by the population size and the initial value range of the parameters and so on, the numerical experiments are carried out. The results show： The improved algorithm can be effectively applied to analysing the data of pumping test, and the calculation problem of aquifer is determined; The larger of the population size, the higher of the accuracy of the algorithm, but it takes too long time ; The range of estimated parameters has a certain influence on the convergence, the convergence is better in smaller range. Comparing with basic flower pollination algorithm, the improved flower pollination algorithm has the advantages of strong search capability, high calculation precision, fast convergence and so on.
