宁南山区水土保持造林优化培植模式研究

Optimized Planting Patterns of Afforestation for Soil and Water Conservation of Mountainous Area in Southern Ningxia

在宁南山区小流域综合治理中,造林按梁峁顶部、陡坡地、沟壑、缓坡滩地等不同立地条件实行不同的优化培植模式,适地适树,混交造林,高标准整地,加强管理,有效提高了成活率和保存率,提高了林木生长量,增加了植被覆盖度。

During the integrated treatment of small watersheds in mountainous area of southern Ningxia,it adopts different optimized planting patterns and methods of selecting tree species according to site factors,mixed afforestation,high-standard soil preparation and strengthened management based on different site factors of top table-land,steep slope land,gullies and flood-land with gentle slope.It has effectively increased the survival rate and growth rate of trees and the coverage of vegetation.
