Research on the Bryophytes’ Diversity and Microhabitat in Wenjiang Park of Sichuan Province

PurposeThis research focused on the diversity and microhabitat characteristics of bryophytes in Wenjiang Park in Sichuan Province. In order to compare the differences in the growth environment of bryophytes in the area, the physical and chemical properties of different matrices were studied quantitatively. This research could provide a reference for the study of the diversity and microhabitat of bryophytes in other urban areas.

MethodsThe diversity, microhabitat characteristics of 7 types and soil physicochemical properties of bryophytes were measured and investigated by means of typical sampling plot methods.

ResultsThere are 13 families, 18 genera and 19 species in this area, and the autochthonous species is dominated, followed by lithophytes and epiphytic. The dominant bryophytes families are Pottiaceae, Thuidiaceae, and the dominant species are Thuidium cymbifolium, Cryto-hypnum tamariscellum, Funaria hygrometrica and Hypnum plumaeforme. The rank of species cover degree is rock, open forest lawn, wetland, forest land, scrubland, lawn and epiphytic, and the rank of species richness is rock, wetland, epiphytic, forest land, open forest lawn, scrubland and lawn. The soil nutrient elements of open forest lawn, wetland, forest land and scrubland were high, however, trace elements of Fe, Mn, Cu and Zn were high in lawn, exchangeable Ca and Mg were high in rock, and the physicochemical properties of epiphytic were stable.

ConclusionsThe bryophytes of Wenjiang Park in Sichuan are various, and the types of autochthonous bryophytes and lithophytes are in higher proportion. In addition to the environmental factors of slope, illumination, litter thickness and human disturbance of microhabitats, the substrates physicochemical property is also the decisive factor affecting the growth and quality of the bryophytes. Above all, bryophytes in wetland, rock, forest land, open forest lawn grows well.
