南水北调中线工程核心水源区石漠化治理探讨

Henan Province,Core Water Source Area of the Middle Route Project of South to North Water Diversion

淅川县是南水北调中线工程渠首和核心水源区,境内有亚洲第1大人工水库丹江口水库,生态区位十分重要,由于水源区周围的山体主要是喀斯特地貌,土壤脊薄,植被稀少,石漠化问题十分突出。为担起一库清水送京津的重任,治理石漠化迫在眉睫。2016年以来,淅川县根据不同石漠化类型,通过人工造林、飞播造林、封山育林、退化林修复等多种方式进行综合治理,积累了丰富的经验,为石漠化地区石漠化治理提供参考。

Xichuan County is the head and core water source area of the South to North Water Diversion Project.There is Danjiangkou Reservoir,the largest artificial reservoir in Asia,in Xichuan County,the ecological location is very important.Due to the karst terrain around the water source area,the soil ridges are thin,the vegetation is sparse,and the problem of rocky desertification is very prominent.In order to take up the important task of sending a reservoir of water to Beijing and Tianjin,it is urgent to control the rocky desertification.Since 2016,Xichuan County has carried out comprehensive management through various methods such as artificial afforestation,aerial seeding afforestation,closed mountain afforestation,and degraded forest restoration according to different types of rocky desertification,accumulating rich experience and providing reference for rocky desertification control in rocky desertification areas.
