Abstract: Situated in central Guizhou Province,China,the Huajiang karst dry-hot valley exhibits a distinctive degree of karst desertification and possesses a relatively fragile habitat.This area's natural environment,ecological industries,and socio-economic factors have drawn considerable scholarly attention.Over the course of nearly 30 years,since the initiation of the "Ninth Five-Year Plan",significant research has been conducted within this region.This research has focused on understanding and controlling karst desertification,enhancing the quality and efficiency of ecological industries,and fostering the coupled development of ecology and economy.Such endeavours have yielded essential theoretical and practical results,aiding in the management of karst desertification and the ecological construction of mountainous regions.This paper delineates the area's fundamental characteristics from four aspects:aridity,high temperatures,valleys,and karst desertification,thereby enriching our understanding of the current habitat situation.Following this,we review the key literature concerning the understanding of karstification and control,cultivation of ecological industries,and improvement in quality and efficiency of these industries from a holistic perspective.Moreover,we utilise long-term cumulative data to analyse areas meriting further investigation.Lastly,based on a regional scale,we suggest future research prospects in three dimensions:quantification and application of micro-habitat characteristics,the interrelationship between vegetation restoration and dual structures,and realisation of the ecological value of ecological products.
