摘要
若尔盖是青藏高原上面积最大的高原湿地,也是黄河上游地区水源涵养地之一。近年来,受气候变化及人类活动的影响,荒漠化、沙化草地的面积不断扩大,植物群落、土壤养分呈现出显著降低的变化趋势,严重威胁着生态安全和当地经济的可持续发展,因而治理土地沙化迫在眉睫。如何恢复草原退化、寻求治理沙化草地的有效方法以及协调人类活动与生物多样性保护的关系,是目前急待解决的难题。该文分析了若尔盖草原退化、沙化的现状及其成因,综述了近年来已用于治理若尔盖沙化方法的应用概况,并分析了其存在的问题,从中探索有效的治理方法。最后对若尔盖沙化的新型治理技术进行了展望,旨在为若尔盖沙化的治理提供新的思路与方法。
Desertification is one of the important issues driven by global climate change.Zoige is the largest plateau wetland on the Qinghai-Tibet Plateau and one of the water conservation areas in the upper reaches of the Yellow Riv?er.In recent years,the area of desertification and desertified grassland has been expanding due to climate change and human activities.The plant community and soil nutrients of desertification grassland have decreased significantly,which seriously threatens the ecological security and sustainable development of local economy.It is urgent to control desertification land.How to restore grassland degradation,find effective methods to control desertified grassland and coordinate the relationship between human activities and biodiversity conservation is a problem to be solved at pres?ent.Based on the present situation and causes of degeneration and desertification in Zoige grassland,this paper sum?marizes the application of desertification control methods in recent years,and analyses the existing problems of these methods,so as to explore effective control methods.Finally,the new control technology of Zoige desertification with pertinence is prospected,and the new technology is popularized and applied in practice,in order to provide new ideas and methods for the control of Zoige desertification.
