为反映农田排水及氮素流失的规律,并推进农田排水面源污染实验教学的发展,将影响农田排水氮素流失的因素进行不同的取值,设计出相应的实验方案,利用DRAINMOD 6.0进行农田排水氮素流失的模拟,并将不同结果进行了对比分析,得出农田排水及氮素流失的一般规律.利用可视化编程软件Macromedia Flash和Macromedia Dreamweaver将模拟结果进行可视化处理,制作出了适用于实验教学的软件.DRAINMOD模拟结果较好地反映出了不同因素下农田排水氮素流失的规律,虚拟实验软件操作简单,直观易懂,有利于虚拟实验教学的改进与发展.
In order to reflect the regularity of farmland drainage and nitrogen loss and to promote the experimental teaching of farmland drainage non-point source pollution, the factors influencing nitrogen drainage of farmland drainage were set to different values, and the corresponding experimental schemes were designed. DRAINMOD 6.0 Drainage and nitrogen drainage loss simulation, and the results of a comparative analysis of different farmland drainage and nitrogen loss of the general rules of the use of visual programming software Macromedia Flash and Macromedia Dreamweaver simulation results were visualized to produce a suitable experiment Teaching software.DRAINMOD simulation results better reflect the nitrogen drainage law of farmland drainage under different factors, virtual experiment software is simple, intuitive and easy to understand, is conducive to the improvement and development of virtual experiment teaching.
