  1. With the using of microsoft visual basic 6. 0, a multimedia computer - aided design system of small type pumping irrigation district is developed in this paper. provided with the live multimedia messages as well as a good man - machine conversation mechanism, this system can help the user to finish the planning of an pumping irrigated area such as the layout of canal system, the selection of pump models, the establishment of the irrigation program, the calculating of canals " parameters, the estimate of the project magnitude, the selection of the field constructions, the economic analysis of the project, the output of results, etc, a new oo ( object oriented ) programming method is adopted in this system, various softwares are integrated in this systems as well by the " automation " technic provided by vb, in addition, the multimedia technic is applied to this system for the first time, it makes the system easy to ope rate. as for the optimization of the canals " section, a new optimization method is adopted based on the existing theories about the canals " section, and in this way, with the purpose of minimizing the project ' s investment as well as a stalized canal, limited by the longituding slope, the canals " best feasible parameters can be deduced. furthermore, a integral method to reckon the earth work is developed in this paper, by this way, the estimate precision of the earthwork is enhanced notably. this paper includes the particular illumination for the developing procedure of each systems " segment, and in the end, the directions of the system are demonstrated in a sample area which lies in the zhaija village, taizhou city, jiangsu province, the running results showed that the initial purposes are achieved effectively, and it has a preferable practicability

    在渠道縱橫斷面優化方面，本文在利用已經比較成熟的縱橫斷面優化理論的基礎上，提出以工程總費用最小為目標函數，以渠道縱坡i為控制變量，以渠道不沖不淤流速及灌區允許地面比降為約束條件，通過縱橫斷面聯動優化的方法得到渠道的最佳工程可行的斷面參數。另外，針對部分地區的取土困難的狀況，本文採用積分法計算渠道工程土方量，從而大大提高了土方量的估算精度，有助於準確控制工程投資規模及資金投向。本文詳細闡述了該系統所採用的編程方法、系統構成、系統各組成模塊的開發過程以及灌區規劃所採用的優化方法及原理，最後應用本系統對泰州市翟家村機電灌區進行規劃設計，運行結果證明其操作比較簡便，界面友好，運行速度快，規劃成果合理，基本達到了系統預定的要求，具備較強的實用性。
