喀斯特石漠化地区草地承载力研究进展与展望

当前我国喀斯特石漠化地区人地矛盾突出,草畜矛盾尖锐,草地承载力严重下降,如何恢复受损的喀斯特草地生态系统、提高草地畜牧业的经济效益、突破石漠化恶性循环,是当下石漠化治理过程中亟需解决的艰巨任务。科学合理地提高草地承载力能够最大化利用草地资源和缓解草畜矛盾,实现草地畜牧业可持续发展,最终达到生态建设与经济效益同步发展的目标。因此,本文主要对草地承载力在喀斯特石漠化地区的研究现状进行了论述,提出国内外关于草地承载力研究拟解决的关键科学问题,并针对现阶段存在的不足进行了展望,以期为喀斯特地区草地畜牧业发展与石漠化治理提供理论支持与借鉴。

Research progress and prospect of grassland carrying capacity in karst rocky desertification area

At present,the contradiction between people and land is prominent,the contradiction between grass and livestock is sharp,and grassland carrying capacity is seriously degraded in the karst rocky desertification areas.How to restore the damaged karst grassland ecosystem,improve the economic benefits of grassland and animal husbandry,and break through the vicious cycle of rocky desertification which is an arduous task that needs to be solved in the current process of rocky desertification control.Scientific and rational improvement of grassland carrying capacity can maximize the use of grassland resources and ease the contradiction between grass and livestock,achieve sustainable development of grassland and animal husbandry,and finally achieve the goal of simultaneous development of ecological construction and economic benefits.Therefore,this paper mainly discussed the research status of grassland carrying capacity in karst rocky desertification area,put forward the key scientific problems of grassland carrying capacity research at home and abroad,and looked forward to the deficiency of the present stage.In order to provide theoretical support and reference for grassland and animal husbandry development and rocky desertification control in karst area.
