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/hm2,灌木纯林总的生态效益达10480.393元/hm2,林粮混作总的生态效益达16854.410元/hm2,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。
The research on typical shellac producing areas shows that there are 4 types and 11 kinds of main shellac cultivation modes that are widely used in our country. Based on the analysis of four typical shellac cultivation modes for carbon fixation and oxygen release, soil conservation and water conservation, the ecological benefits of different shellac planting modes were discussed. The results showed that from the perspective of ecological benefits, the total ecological benefits of pure tree forests reached 10,917.448 yuan / hm2, the total ecological benefits of pure shrubs reached 10,480.393 yuan / hm2, and the total ecological benefits of mixed forestation were 16,854.410 yuan / hm2. Different planting patterns The main ecological benefits of carbon fixation and oxygen release, accounting for more than 99% of the model ecological benefits.
