河南省淅川县是南水北调中线工程渠首所在地,境内有着我国最大的人工淡水湖丹江口水库,其生态环境关乎整个中线工程的水质安全。然而,淅川县却存在不同程度的石漠化土地,特别是丹江口水库周围石漠化较严重。为做到“一江清水入库,一库清水北送”,开展人工造林,恢复生态环境,石漠化治理刻不容缓。为提高造林成活率,依据不同石漠化程度、立地类型等,提出了石漠化地区造林的物种选择、整地、抚育等方面相关技术,以期为淅川县石漠化治理工作提供参考。

Xichuan County of Henan Province is the source of the middle route project of South to North Water Diversion with the China’s largest artificial freshwater reservoir.And its ecological environment affects the water quality and safety of the whole middle route project.There are varrying degrees of rocky desertification land in Xichuan County,especially the rocky desertification around Danjiangkou reservoir is more serious.In order to achieve the goal of “a river of clear water flowing into the reservoir,a reservoir of clean water dispatched to the north”,artificial afforestation and restore ecological environment should be implemented,it is urgent to control rocky desertification.In order to improve the survival rate of afforestation,according to the degree of rocky desertification and site type,the species selection,soil preparation and tending techniques of afforestation in rocky desertification area of Xichuan County were put forward.
