摘要
紫胶典型产区的调查研究表明,我国在生产上广泛使用的主要紫胶培育模式有4类11种。通过对典型的4种紫胶培育模式进行固碳释氧、保育土壤及涵养水源分析,探讨了不同紫胶种植模式下的生态效益。结果表明：从生态效益看,乔木纯林总的生态效益达10917.448元/hm^2,灌木纯林总的生态效益达10480.393元/hm^2,林粮混作总的生态效益达16854.410元/hm^2,不同种植模式的生态效益以固碳释氧为主,占了模式生态效益的99%以上。
There were 11 main Lac cultivate pattern in China.The eco-efficiency of different of Lac cultivate pattern was studied through analysis nitrogen fixation and oxygen release,conserve soil quality,and water conservation.The result showed that in the aspect of eco-efficiency,the ecologic profits of pure forest was 10917.448 yuan per hm2.Ecologic profits of forest-shrubs was 10480.393 yuan per hm2.Profits of forest-grain pattern was 16854.410 yuan per hm2.Efficiency of oxygen-release with carbon-sequestration was the mainly ecological benefits in different patterns which accounts for more than 99 percent of the eco-efficiency model.
