Followings are programs of basic and educational ecological theories.

You have to know that most of these models are only basic and oversimplified models. 

If you plan to use them in your research, you have to understand the theory and limitation.

I didn't update these programs since 2010. You can find similar models on the internet.

這些教學用的程式都是過度簡化的模型,不應用於實際研究與資料分析。

自2010年後,本人不再更新這些教育程式,使用者可以自行設計或使用其他網頁的程式。

Most programs are designed in two versions, i.e., Graph32.ocx and MSChart.ocx.  If you encounter problems in installing programs with Graph32.ocx,  please try the MSChart.ocx version.  They are both user-friendly.
