Landscape Corridors (LSCorridors): a new software package for modeling ecological corridors based on landscape patterns and species requirements

1.Maintaining connectivity is one of the main challenges for biodiversity conservation worldwide. Ecological corridors are important to maintain landscape connectivity, but their efficiency depends on landscape patterns and species responses at different spatial extents and landscape contexts. 2.We developed a new ecologically oriented free software package, LandScape Corridors (LSCorridors), to improve ecological corridor design by considering biodiversity responses to landscape attributes at a variety of spatial extents. LSCorridors considers stochastic variation, species perception and landscape influence on organisms in the design of ecological corridors. In addition to the least cost path algorithm, we propose four different methods for the simulation of multiple-path functional ecological corridors. One method uses the information for each pixel separately whereas the three other methods permit corridor simulation considering the landscape context at different spatial extents. 3.L...

1. 维持景观连通性是全球生物多样性保护的主要挑战之一。生态廊道（Ecological Corridors）对维持景观连通性至关重要，但其效能取决于不同空间尺度与景观背景下的景观格局以及物种响应特征。2. 我们研发了一款全新的生态导向型免费软件工具包LandScape Corridors（简称LSCorridors），旨在通过考量不同空间尺度下生物多样性对景观属性的响应特征，优化生态廊道的设计流程。LSCorridors在生态廊道设计环节中，充分纳入了随机变异、物种感知以及景观对生物的影响等关键要素。除最小成本路径算法（Least Cost Path Algorithm）外，我们还提出了四种可用于模拟多路径功能性生态廊道的方法：其中一种方法仅单独利用单个像素的信息，其余三种方法则支持在不同空间尺度下结合景观背景开展廊道模拟。3.
