麻江县退耕还林主要优化配置模式分析

[目的]促进麻江县退耕还林后续产业的发展,为有关部门提供参考。[方法]通过对麻江县退耕还林工程中的主要造林模式进行调查分析,提出适合麻江县发展的造林模式,[结果]麻江县的退耕还林区划把全县划分为3个退耕还林类型区、6个立地类型亚区、2个立地类型组。根据气候特点和立地类型,结合麻江县森林生态建设的总体目标,提出了当前既能提高森林植被、保持水土,又能增加农民收入的造林模式是:林药结合模式、林草结合模式、经济林模式和杉竹混交模式,且从长远来看,杉竹混交模式最具发展潜力。[结论]该研究为麻江县退耕还林工程的进一步发展提供了依据。

Analysis of Main Afforestation Models for Returning Farmland to Forst in Majiang County

[Objective] The research aimed to promote the follow-up industry development after returning farmland to forest in Majiang county and provide basis for the relevant departments. [Method] Based on the investigation and analysis of main afforestation models in the project of returning farmland to forest in Majiang county, an afforestation model which was suitable for the development of Majiang county was put forward. [Result] In the regionalization of returning farmland to forest in Majiang county, the total county was divided into 3 type areas of returning farmland to forest, 6 subareas of site types and 2 groups of site types. According to the climatic characteristics and site types, combined with the general target of forest ecological construction in Majiang county, the current afforestation models were put forward as the complex model of forest and herbal medicine, the complex model of forest and grass, economic forest model and the intercropping model of Cunninghamia lanceolata and bamboo, which could not only enhance the forest vegetation and conserve soil and water, but also increase the peasants ' income. In the long run, the intercropping model of C. lanceolata and bamboo had the most development potential. [Conclusion] This research provided basis for the further development of the project of returning farmland to forest in Majiang county.
