- Title:
- Research on Vegetation Recovery Technology in Semi-arid Degenerated Mountainous Area in South Ningxia
- 分类号:
- X171.1
- 摘要:
- 通过对半干旱退化山5年退耕还林地不同坡向、坡位、坡度的调查,得出采用人工整地技术种草种树,调整土地利用结构,增加灌木和种草的比例,采用合理的土地利用结构,建立各种类型的混交林和林草立体复层林,形成稳定的植物群落的办法就能保证群落稳定持续地发展,从而为植被恢复和土地的合理利用等做出正确的规划.
- Abstract:
- Through the investigation of the different slope,slope position and slope gradient of 5 years’ land of returning farmland to forest in semi-arid mountainous area,the results shows that applying soil tillage to plant grass and tree to adjust land use structure,increase the ratio of shrub and grass,and employing reasonable land use structure to establish different types of mixed forest and composition layers of forest stereoscopically and form stable plant community can guarantee the community to develop continuously,so as to make correct planning in agricultural production,vegetation recovery and rational use of land etc.
