摘要：以喀斯特盆坝地旧州镇、低山丘陵朱家场镇、喀斯特峡谷掌布镇及喀斯特中山新窑镇4个西南喀斯特山区不同地貌贫困乡镇为例,运用Fragstats4.2、ArcGIS10.5软件对我国西南喀斯特山区4个贫困乡镇景观脆弱度进行评价。结果表明:旧州镇以耕地为主,受人类活动影响大,景观脆弱度较高;朱家场镇以林地与建设用地镶嵌分布为主,生态系统易受到损坏,景观脆弱度较高。掌布镇以林地及灌草丛为主,景观稳定性强,脆弱度较低;新窑镇以灌草丛为主,人类活动干扰较小,景观脆弱度较低。4个乡镇景观脆弱度空间异质性突出。景观结构及其空间格局是影响喀斯特山区不同地貌贫困乡镇景观脆弱度的重要因素。
in this paper,we take four poor rural townships in the karst region of southwest China with different landform types(Jiuzhou Town with karst basin,Zhujiachang Town with low mountain,Zhangbu Town with karst valley and Xinyao Town with karst mid-mountain)as examples,to evaluate the landscape vulnerability by using Fragstats4.2 and ArcGIS10.5 software.The results showed that:Jiuzhou Town is mainly cultivated land,which is greatly influenced by the human activities,and the landscape vulnerability is high.Zhujiachang Town is mainly inlaid and distributed by forestland and construction land,the ecosystem is vulnerable and the landscape vulnerability is high.Zhangbu Town is mainly forestland and shrub-grasslands,with strong landscape stability and the landscape vulnerability is low.Xinyao Town is mainly shrub-grasslands,which is less influenced by human activities,and the landscape vulnerability is low.The spatial heterogeneity of landscape vulnerability of four towns is prominent.Landscape structure and spatial pattern are important factors that affect the landscape vulnerability of these towns in the karst mountainous areas.
