Ecological benefits of rubber tea chicken eco agricultural model & a typical tropical agro forestry system in Wenchang city of Hainan Province was studied with quantitative study and qualitative analysis compared with single culture and inter cropping rubber gardens. 以海南省文昌市典型的胶－茶－鸡农林复合模式为研究对象，以单作胶园、胶茶间作园为对照，采用定量研究与定性分析相结合的方法，研究其生态效益进行。
In this system the contribution rates of rubber plantation, tea tree and chicken to the total output are 0.03,003 and 0.94 respectively. It shows that chicken plays an important role in the funds movements of this system. 在该系统中，胶、茶、鸡对总产出的贡献率分别为003、003、094，可见，鸡在该系统资金流中起重要作用。
Results showed that the model could improve soil physical structure and fertility, which increases the yield of rubber and tea, the quality of chicken. Thus, the agro forestry model could yield high ecological benefits. 结果表明，该模式可明显改善土壤物理性状，提高土壤肥力和胶、茶产量，改善鸡的品质，因此，该模式具有较高的生态效益。
