摘要

[目的]探究生态安全用地格局对维持区域生态系统平衡的重要作用，为广西壮族自治区寿城自然保护区的发展建设决策提供一定的依据。[方法]基于景观安全格局理论与MCR模型，借助GIS平台和Fragstats 4.2软件，采用人机交互式遥感图像解译方法获取寿城自然保护区2013年、2017年两期土地利用类型数据，从景观格局演变、安全格局构建两方面对寿城自然保护区进行研究。[结果]寿城自然保护区土地利用类型斑块空间分布上趋于分散，斑块破碎化程度增加，斑块边缘形状趋于复杂；划分了2013年、2017年人类活动的发展核心区、发展过渡区、发展调整区、发展限制区4种人类活动用地类型，并针对不同类型的人类活动用地提出相应的建议与优化方案。[结论]人类活动对寿城自然保护区的景观变化有重要影响，人类活动用地面积在发展核心区、过渡区、优化区均有增加趋势，在生态功能最强的限制区内有所下降。

Abstract

[Objective] The important role of ecological security land use pattern in maintaining regional ecosystem balance was explored in order to provide a basis for the development and decision-making of Shoucheng Nature Reserve in Guangxi Zhuang Autonomous region.[Methods] Based on the theory of landscape security pattern and MCR model

GIS platform and Fragstats 4.2 software was adopted

human-computer interactive remote sensing image interpretation method was used to obtain the land use type data of Shoucheng Nature Reserve in 2013 and 2017. The evolution of landscape pattern and the construction of security pattern were studied in Shoucheng Nature Reserve.[Results] The spatial distribution of land use patches in Shoucheng Nature Reserve tended to be scattered

the fragmentation of patches increased

and the shape of patch edge tended to be complex. Land use for human activities in 2013 and 2017 was divided into four types:development core area

development transition area

development adjustment area and development restricted area. Accordingly

the corresponding suggestions and optimization schemes for different types of human activity land were proposed.[Conclusion] Human activities have an important impact on the landscape change of Shoucheng Nature Reserve. The areas of human activities show an increasing trend in the development core area

the transition area and the optimization area

but a decreasing trend in the most ecologically functional restricted area.
