To elucidate the plant response to habitat fragmentation, 18 interdune lowlands with different sizes in active sand dunes of Horqin Sand Land were selected, and the interdune lowland was considered as fragmented habitat patch. In our study, the effect of patch size on plant distribution pattern was explored and different protocols of species diversity conservation were proposed. Our results showed different plant sensitivities to habitat fragmentation: type I, species are restricted by patch area and distributed regularly in fragments; type II, species are not restricted by patch area, and their distribution is irregular in fragments; type III, species mainly distributed in large fragments; type IV, species mainly distributed in small fragments; type V, species mainly distributed in middle-sized fragments. Exploring the effects of fragmentation habitat size on plant species diversity and its distribution pattern will provide theoretical basis for plant diversity conservation in semi-arid sand dunes.
