Landscape connectivity measures based on metapopulation theory were developed over 20 years ago. Initially, they applied classic metapopulation models to simple patch-based representations of landscapes using vector spatial data structures. Realism was improved by developing dynamic estimates of occupancy and metapopulation capacity, the latter providing a measure of the integrated habitat amount. Such measures are used to estimate the ability of habitat networks to support metapopulation persistence. The original methods for occupancy mapping and metapopulation capacity were adapted to work with fine-grained, continuous-value raster data. That step shifted the method outside of the classic metapopulation model which left some methodological issues unresolved; in particular, what has been termed the deceptive paradox of patch-based connectivity whereby perverse and what we describe as inequitable results are obtained through arbitrary circumscription of the analysis grid and through the trading of habitat between habitat quality, extent and connectivity. We provide a solution to this issue and apply it within the frame of Drielsma and Ferrier's (2009) raster-based Rapid Evaluation of Metapopulation Persistence (REMP).

We demonstrate our solution using simple hypothetical examples; and in order to demonstrate the practicality of our approach to real-world settings, we apply the approach to habitat suitability mapping of the White-browed Treecreeper (Climacteris affinis) in south eastern New South Wales, Australia.

在20多年前就开发了基于人口迁移理论的景观连通性措施。最初，他们使用向量空间数据结构将经典的种群模型应用于基于补丁的简单景观表示。通过开发动态的占用率和人口迁移能力估计值，改善了现实主义，后者提供了对生境综合数量的衡量。这些措施用于估计栖息地网络支持种群持久性的能力。原始的占位图和人口分布能力的方法适用于细粒度，连续值的栅格数据。这一步将方法转移到经典的人口模型之外，从而导致一些方法学问题尚未解决。特别是所谓的基于补丁的连通性的欺骗性悖论，通过任意限制分析网格以及通过在栖息地质量，程度和连通性之间进行栖息地交易，可以获得不正当的结果以及我们所说的不公平结果。我们提供了针对此问题的解决方案，并将其应用在Drielsma和Ferrier（2009）基于栅格的元种群持久性快速评估（REMP）的框架内。

我们使用简单的假设示例演示我们的解决方案；为了证明我们的方法在实际环境中的实用性，我们将该方法应用于澳大利亚新南威尔士州东南部的白眉树爬虫（Climacteris affinis）的栖息地适宜性制图。
