Abstract Full-scale intensive silvicultural activities, such as afforestation and rehabilitation, can deteriorate the fragile structural features and functions of karst ecosystems. Within these ecosystems, degraded and fragmented habitats can only be connected to each other through a landscape network that poses a positive umbrella effect over these areas. The aim of this research was to determine suitable eco-regions and landscape corridors for reforestation and restoration based on several biotic and abiotic habitat factors using Analytic Hierarchic Processes (AHP) and Geographic Information System (GIS). This approach was targeted at plant species naturally associated with the degraded Mediterranean karst ecosystem, such as Pinus brutia Ten, Juniperus drupacea, Styrax officinalis L., Pistacia terebinthus L., Laurus nobilis L., and Cerasus mahaleb L. in the study area, which is located in the Andirin Sarimsak Mountains in Kahramanmaras, Turkey. In this study, potential landscape corridors and their habitat qualities have been identified for the target species, where ratings from “poor” to “best” were assigned depending on the condition of degradation. Of the 33 identified corridors, 8 were characterized as ‘poor’, 10 as ‘average’, 10 as ‘good’, and 5 as ‘best’ Specifically, the ‘best’ corridors are recommended for afforestation, while rehabilitation is suggested for ‘poor’ corridors to increase the effectiveness of landscape networks in the degraded karst ecosystem.

利用GIS和AHP技术确定地中海退化喀斯特生态系统中植被连通性的生态网络

摘要 全面的集约化造林活动，如植树造林和恢复，会破坏喀斯特生态系统脆弱的结构特征和功能。在这些生态系统中，退化和支离破碎的栖息地只能通过景观网络相互连接，从而对这些地区产生积极的保护伞效应。本研究的目的是利用层次分析法 (AHP) 和地理信息系统 (GIS)，根据多种生物和非生物栖息地因素，确定适合重新造林和恢复的生态区域和景观走廊。这种方法针对与退化的地中海喀斯特生态系统自然相关的植物物种，例如 Pinus brutia Ten、Juniperus drupacea、Styrax officinalis L.、Pistacia terebinthus L.、Laurus nobilis L.、和 Cerasus mahaleb L. 在研究区，位于土耳其 Kahramanmaras 的 Andirin Sarimsak 山脉。在这项研究中，已经确定了目标物种的潜在景观走廊及其栖息地质量，其中根据退化情况分配了从“差”到“最好”的评级。在确定的 33 条走廊中，8 条为“差”，10 条为“一般”，10 条为“好”，5 条为“最佳”。贫困走廊，以提高退化的喀斯特生态系统中景观网络的有效性。已经为目标物种确定了潜在的景观走廊及其栖息地质量，其中根据退化情况分配了从“差”到“最好”的评级。在确定的 33 条走廊中，8 条为“差”，10 条为“一般”，10 条为“好”，5 条为“最佳”。贫困的走廊，以提高退化的喀斯特生态系统中景观网络的有效性。已经为目标物种确定了潜在的景观走廊及其栖息地质量，其中根据退化情况分配了从“差”到“最好”的评级。在确定的 33 条走廊中，8 条为“差”，10 条为“一般”，10 条为“好”，5 条为“最佳”。贫困的走廊，以提高退化的喀斯特生态系统中景观网络的有效性。
