Resource endowment and conservation value of the karst area in Southwestern Guangxi
摘要
Abstract
Natural reserves serve as the core carrier of ecological conservation and play a pivotal role in safeguarding national ecological security.The southwest of Guangxi Zhuang Autonomous Region,bordering Vietnam,experiences a tropical and southern subtropical monsoon climate and features extensively distributed typical tropical and subtropical karst landforms,including peak-cluster depressions,peak-forest plains,sinkhole groups,caves,and canyons.Notably,this region preserves large-areas of northern tropical limestone mountain seasonal rainforests,which are rare both in China and globally.Boasting high integrity and good authenticity,this forest ecosystem provides favorable habitats for flagship species such as plants of the Cycas and Taxus genera,as well as Parashorea chinensis,Excentrodendron hsienmu,Nomascus nasutus,Trachypithecus francoisi,and Trachypithecus poliocephalus. This region harbors exceptionally rich biodiversity.A total of 695 wild vertebrate species have been documented,including 36 species endemic to China,18 listed as Class Ⅰ national key protected wild animals,and 69 as Class Ⅱ.Additionally,there are 4,262 wild vascular plant species belonging to 1,349 genera of 254 families.Among these plants,1,171 are endemic to China,16 are Class Ⅰ national key protected wild plants,and 56 are Class Ⅱ.As part of the Indo-Burma Biodiversity Hotspot,this region serves as a global concentration site for the most endangered primates,is one of the three major centers of plant endemism in China,and is a priority area for biodiversity conservation in the mountainous regions of Southwestern Guangxi.Inhabited by ethnic minorities,it is home to a World Cultural Heritage site-the Zuojiang Huashan Rock Art Cultural Landscape,and also boasts abundant revolutionary tangible and intangible heritage,such as the Baise Uprising Memorial Hall and the Zuoyoujiang Revolutionary Base Area,thereby serving as an important part of the community for the Chinese nation.Furthermore,it functions as a vital node for consolidating the ecological security barrier along the China-Vietnam border and for building a community with a shared future for all life on Earth. Based on the relevant requirements for establishing and developing the system of natural reserves,this study conducts assesses and concludes that the karst region in Southwestern Guangxi holds exceptional conservation value in terms of national representativeness,ecological significance,and cultural uniqueness.This study particularly emphasizes the integrated and systematic protection of the karst ecosystem in this region,recommending that the Forestry Bureau of the Autonomous Region take the lead in establishing an extensive cooperation mechanism among governments,universities,research institutes,and enterprises.Furthermore,it suggests integrating the natural reserves in the karst region within Southwestern Guangxi to establish the Natural Reserve Alliance of Southwestern Guangxi. This study addresses the challenges facing the karst region in Southwestern Guangxi,including inadequate coverage of natural reserves,significant contradictions between ecological protection and economic development,and insufficient innovation capacity for cultural preservation and inheritance.It proposes targeted measures such as further advancing the integration and optimization of natural reserves,establishing an integrated monitoring system,implementing ecological restoration projects,promoting the integration of culture and tourism with science popularization and education,strengthening cross-border ecological cooperation,and achieving comprehensive ecosystem protection.These initiatives aim to promote the coordinated development of ecological protection and economic growth,continuously strengthen the protection of the region's core values,consolidate the ecological security barrier along the China-Vietnam border,achieve greater progress in the high-quality development of border and ethnic minority areas,and make more contributions to safeguarding national security.关键词
