我国热带地区胶茶鸡农林复合系统能流分析(英文)

Analysis of Energy Flow of Rubber tea chicken Agro forestry System in Tropical Area of China

以海南省文昌市典型的胶茶鸡农林复合系统模式为研究对象，分析了我国热带地区单作胶园、胶茶间作园及养鸡胶园的能流路径、能量输入输出结构及能流转化效率⒚结果表明，单作、间作及养鸡胶园的光能利用率依次提高，其能量产投比分别为１５０，１８８，０２０；有机能投入比分别为 ０１３８，０１１９，０９７７，养鸡胶园最高；无机能投入比分别为０８６２，０８８１，００２３；养鸡胶园中人工辅助能投入比相对减少，系统稳定性增强。

Energy flow of rubber tea chicken eco agricultural model—a typical tropical agro forestry was studied in Wenchang Municipality of Hainan province Energy flow path, input and output structure and conversion efficiency of rubber, rubber tea and rubber tea chicken gardens were analyzed The results showed that the utilization efficiency of solar energy in the three gardens increased gradually Their energy output/input ratios were 1 50, 1 88 and 0 20, respectively The organic energy input/total input ratios were 0 138, 0 119, 0 997, and inorganic input/total input ratios were 0 862, 0 881, 0 023, respectively In rubber tea chicken system, the artificial subsidiary energy input was decreased comparatively and the system's stability and energy output increased
