1.种群生存能力取决于栖息地面积、栖息地质量、栖息地的空间排列（聚集和连接）以及非繁殖地（基质）的性质。Hodgson等人[Journal of Applied Ecology 46（2009 964）]和Doerr，Barrett & Doerr（Journal of Applied Eology，2011）不同意这些景观属性在使物种能够持续存在并改变其分布以应对气候变化方面的相对重要性。一个简短的发表的证据表明，栖息地面积和质量的变化比栖息地的空间排列或干预土地的性质的变化有更格尔影响。即使基质中的结构特征对扩散率有可测量的影响，这也不一定会导致种群生存力的显著增加。Laige和高质量的栖息地提供了源种群和殖民地的位置，因此它们是物种改变其分布以应对气候变化的能力的主要决定因素，因为种群必须在每个新的区域相继建立。合成与应用。尽可能多地保留高质量的自然和半自然栖息地应该成为保护的重点，特别是在气候变化时期。
1. Population viability can depend on habitat area, habitat quality, the spatial arrangement ofhabitats (aggregations and connections) and the propcrtie of the intervening non-breeding (matrix) land. Hodgson et al. [Journal ofApplied Ecology 46 (2009 964] and Doerr, Barrett & Doerr (Journal of Applied Eology, 20l1 disagree on the relatie importance of these landscape attributes in enabling species to persist and change their distributions in response to climate change.2. A brief ieiev of published evidence suggests that vaiiations in habitat aiea and quality hae big ger effects than variations in spatial arrangement of habitats or properties of the intervening land. Even if structural features in the matrix have a measurable effect on dispersal rates, this does not necessarily lead to significant increases in population viability.3. Laige and high quality habitats piovide source populations and locations for colonisation, so they are the main determinants of the capacity of species to shift their distributions in response to climate change because populations must be established successively in each new region.4. Synthesis and applications. Retaining as much high quality natural and semi-natural habitat as possible should iemain the key focus foi conseration especially dining a period of climate change.
