黔中花江喀斯特干热河谷地区石漠化发育较为典型,生境十分脆弱,其自然环境、生态产业和社会经济均被学者广泛关注.自"九五"计划实施以来的近30年,学者在该区开展了认识石漠化、治理石漠化、生态产业提质增效、生态与经济耦合发展等诸多研究,取得了 一系列重要理论和实践成果,推动石漠化治理和山区生态建设,其中的"顶坛模式"是石漠化治理的典型经验.本研究首先从干、热、河谷深切、石漠化4个方面阐明了该区的基本特征,然后从认识喀斯特石漠化、石漠化治理生态产业培育、生态产业提质增效等视角,对现有主要文献进行梳理,并结合长期积累的资料,分析了下一步值得深入研究的问题,最后以区域为尺度,展望了未来研究的三个重要方向,即小生境特征的量化及应用、植被恢复与二元结构的关系和生态产品的生态价值实现.
Huajiang Dry-Hot Valley in Central Guizhou Province:Crrent Knowledge and Prespectives
Situated in central Guizhou Province,China,the Huajiang karst dry-hot valley exhibits a distinc-tive degree of karst desertification and possesses a relatively fragile habitat.This area's natural environ-ment,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 de-sertification,enhancing the quality and efficiency of ecological industries,and fostering the coupled devel-opment 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 in-vestigation.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.
