中文摘要：
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.
英文摘要：
To react the properties of farmland drainage and nitrate loss and prompt the development of experimental teaching in farmland drainage and nitrate loss,the research designed 76 programs according the factors that influence farmland drainage and used DRAINMOD 6.0 to sum up the law of nitrate loss in farmland drainage.Also,we visualize the results and make the virtual teaching software based on visual programming software Macromedia Flash and Macromedia Dreamweaver.From the results of the experiment,we can see that the software is excellent,it realizes the rules of agricultural drainage and nitrate loss,also with the characteristics of easy-handling,straightforwardness,which is beneficial to the improvement and development of experimental teaching.
