摘要: 共和盆地在自然带上属半湿润森林草原地带与干旱荒漠地带之间的高原温带内半干旱干草原和干旱荒漠草原的过渡生物气候亚带, 高寒干旱的气候和丰富的第四纪砂物质是我国沙漠化得以发生、发展的地区之一, 这对当地农牧业生产, 特别是龙羊峡库区造成巨大威胁。为此, 本文探讨了该区土地沙漠化现状、危害的基础上, 并提出土地沙漠化的初步区划、防治原则、途径和措施。

Abstract: The natural zone of Gonghe basin belongs to the transitional bioclimatic subzone of semi-arid steppe and arid desert steppe within plateau temperate zone between sud-humid forest steppe and arid deserts. The cold, dry plateau climate and abundant sandy material in Quaternary strata there led to the genesis and development of desertification, and caused severe threat to the production of local farming and animal husbandry, especially the safety of Longyangxia reservior. Baseo on the research of current, situation and harms of desertification there, this article proposed the principles, ways and measures to combat desertification,following a preliminary regionali-zation.
