城市化被认为是对生物多样性的主要威胁。在城市化地区，森林和草原等栖息地往往是分散的。支离破碎的栖息地之间的基质会影响生物多样性，因为其中一些可以作为某些物种的栖息地(好客的基质)。景观中生物多样性的基质，即零碎的栖息地和基质，可能会受到景观中物种的扩散能力的影响，因为这可能会影响适宜居住的基质的可用性。在这项研究中，我们评估了当地条件和周围基质对两种不同扩散能力的物种多样性的影响，即扩散能力相对较低的步甲科和扩散能力相对较高的异翅目昆虫。东京是日本人口最多的地区。步甲科的多样性受当地栖息地大小和周围宜居基质数量的影响不大，而异翅目受当地栖息地大小和周围适宜基质数量的影响较大。因此，对于扩散能力相对较高的物种，碎片化的小生境可能具有更高的栖息地质量，这取决于周围的友好基质。为了促进城市公园的生物多样性保护，既需要本地栖息地管理，也需要矩阵管理。
Urbanization is recognized as a major threat to biodiversity. Within an urbanized area, habitats such as forests and grasslands are often fragmented. Matrixes between fragmented habitats can influence the biodiversity because some of these can act as habitats for some species (hospitable matrixes). The importance of matrixes for biodiversity within the landscape, i.e., the fragmented habitat and matrix, can be influenced by the dispersal ability of the species within the landscape because this can affect the availability of the hospitable matrix. In this study, we evaluated the effects of both local conditions and the surrounding matrix on the species diversity of two taxa with different dispersal abilities, i.e., Carabidae, which has relatively low dispersal ability, and Heteroptera, which has relatively high dispersal ability, in the grassland of urban parks in Tokyo, the most populated region in Japan. The diversity of Carabidae was not strongly influenced by the local habitat size or the amount of surrounding hospitable matrix; however, Heteroptera was strongly influenced by both the local habitat size and amount of surrounding hospitable matrix. Thus, fragmented small habitats might have higher habitat quality depending on the surrounding hospitable matrix for species with relatively high dispersal ability. To promote biodiversity conservation in urban parks, both local habitat management and matrix management are required.
