This paper makes an analysis of the Doppler speed charts of clear weather and the echoes of large-area precipitation. It also singles out the Doppler speed charts of typical wind fields. In addition, this paper analyzes Doppler radars detecting process of the strong convection current weather system. It also conducts a thorough analysis of Doppler echo features of some hazardous weather, such as cell storm and downward storms. Based on this research and analysis, the paper reaches some important conclusions concerning the detecting methods using Doppler radar and the analysis of the information gathered by Doppler radar.

Based on the radar dense data of convectional cloud on June 12,2004 in Yongdeng county,choosing two similar convectional clouds as seeding and non-seeding cloud,the remarkable changes of radar echo parameters of the seeding cloud compared with the non-seeding cloud were discussed in this paper,and the rain enhancement effect was evaluated primarily with ground observational rainfall data.The results show that many aspects of the seeding cloud,such as precipitation,life characteristic and vertical characteri...

利用2004年6月12日甘肃省永登县雷达观测对流云的加密资料，选取了2次相似对流云过程分别作为目标云和对比云，探讨了目标云作业前后较对比云雷达回波有关参数的显著变化，并结合地面雨量点观测资料对地面人工增雨作业效果进行了初步分析，结果表明：目标云在降水、生命期特征、回波垂直特征参数变化方面，表现出作业前后较对比云存在明显差异，目标云作业40 m in后地面产生0.6 mm降水，而对比云则从新生发展到减弱消散阶段经历较短的时间(30 m in)，地面并无降水产生，从而推断本次人工增雨达到了一定的预计效果。

The result shows that: The variation rhythm of the sensitivity index changed unanimously for Jensen,Blank and Stewart water production functions of spring wheat in Liangzhou city,the volume is small in the former stage,then become large at the middle stage,and less at the last stage. Jensen and Stewart water production functions are better of spring wheat in Gulang County in 1987-1989. The Variation rhythm of water deficiency sensitive index is unanimous: the volume are small at first,then large at middle,and diminish at last. The Variation rhythm of water deficiency sensitive index is unanimous in Jensen,Blank and Minhas of flax in Liangzhou county in 1987-1989. The water deficiency sensitive index in Gulang district in 1987-1989 models bad,are too many minus. 3 Establishing the non-linear model to definitive the irrigation quota and dimension of single crop,according the three prototype Precipitation,allocating the limited water optimally according to full water supply,95 percent,75 percent and 50 percent. Economy benefit is the biggest aim function,so getting three groups for irrigation quota,irrigation dimension and benefit,the biggest benefit is the most optimal result.

结果表明：1985-1986 年凉州春小麦Jensen 模型、Bl(来源：10a1ABC论文网www.abclunwen.com)ank 模型和Stewart 模型的敏感指数变化规律接近一致，在前期较小，中期增大，最后再减小。1987-1989 年古浪春小麦水分生产函数以Jensen 模型和Stewart 模型拟合较好，其敏感指数变化规律比较一致，敏感指标值前期较小，中期增大，后期又减小。1983-1985 年凉州亚麻水分生产函数以Jensen 模型、Blank 模型和Minhas 模型敏感指标值变化规律比较一致：先减小，后增大，最后再减小。1987-1989 古浪亚麻敏感指数出现负值较多，模型拟合较差。3 建立单作物种植条件下灌溉定额与灌溉面积的确定的非线性规划模型，将有限的水量按照充分供水，95%、75%和50%供水来分配水资源，以经济效益最大为目标函数，得出三组灌区灌溉面积和效益结果，其中以效益最大为最优解。
