With the increase of land-use change, habitat fragmentation has become a major factor affecting plant diversity. Generally, when the adult density is high, the survival rate of conspecific saplings may decline and provide more resources and space for other species to maintain a high local species diversity. Therefore, the spatial relationship of conspecific saplings and adults (SRCSA) can regulate plant diversity. However, very few studies have assessed SRCSA within fragmented forests, and we still largely unknown the relationship between SRCSA and species diversity in fragmented landscapes.

森林碎片中同种幼树和成虫分布的不对称关系

随着土地利用变化的增加，生境破碎化已成为影响植物多样性的主要因素。通常，当成虫密度高时，同种树苗的存活率可能下降，并为其他物种提供更多的资源和空间，以维持较高的本地物种多样性。因此，同种树苗与成虫的空间关系（SRCSA）可以调节植物的多样性。但是，很少有研究评估零散森林中的SRCSA，而我们仍然很大程度上不清楚零散景观中SRCSA与物种多样性之间的关系。
