我国热带地区典型农业生态工程所在系统研究——胶-茶-鸡农林禽复合生态模式系统的效益分析

System Including Typical Agricultural Ecological Engineering in Tropical Areas of China:Analysis of the Major Indicators of Existing System of Rubber-Tea-Chicken Agro-Forestry Model

摘要: 该文介绍了海南省文昌市一个典型的农业生态工程——胶－茶－鸡农林禽复合生态模式，在对模式发展阶段进行划分的基础上，分析了不同阶段模式所在系统的主要社会－经济－自然因子的变化动态，研究表明，随着生态工程建设的深入，其所在系统的物质投入产出结构、农民收入结构、经济结构和农村生态环境均得到了改善，自然资源开发力度增强，农村经济效益提高，因此，该农林禽复合生态模式系统的发展与生态工程建设具有密切的关系。

Abstract: The rubber-tea-chicken eco-agricultural model——a typical tropical agricultural ecological engineering in Wenchang municipality of Hainan Province was introduced systematically. On the basis of dividing the model developing stage, the changing trends of the major social, economic and natural factors of the system in different stages were analysed. Results showed that the material input and output structure, peasants income structure economic structure and rural environment of the system were improved. The development of natural resources was strengthened and rural economic benefit was increased. Thus, the system development has close relationship with the ecological engineering construction.
