元谋干热区退化山地复合生态农业模式自然资源的利用研究

Study on nature resource utilization efficiency of compound eco-agricultural models on involution mountain land in Yuanmou dry hot valley

通过对元谋干热区退化山地复合生态农业模式3年的监测，分析总结了4种复合生态农业模式系统对光能、水分、土地3种自然资源的利用效率，并与单作系统进行了比较。结果表明，复合模式系统的总光能的利用率、总水分利用率和土地利用率都比单作系统有明显的提高，说明多层次的复合生态农业模式系统的建立，更有利于光、水、土地自然资源的充分高效利用。

Long-term monitoring for 3 years conducted of compound eco-agriculture models on involution mountain land, analyzed and sum up the utilization efficiency of nature resources which are light energy , water and ground on compound eco-agricultural models, and to compared with monoculture system .The result showed the total utilization efficiency of light energy, water and ground was higher on compound model system than on monoculture system, and showed the multitiered compound model systems are more advantaged on the efficient utilization of nature resources which are light energy, water and ground.
