Species composition and diversity analysis of autophytes in Lanzhou riverside parks
To investigate and study the species composition and diversity characteristics of autophytes in four river-side parks in Lanzhou,so as to provide a reference for low-cost,low-maintenance and wild natural landscape planning,a total of 344 quadrats were selected from west to east in the main urban section of Lanzhou of the Yellow River to investi-gate the species composition and distribution characteristics of authigenic plants in the riverside parks.The results showed that:there were 163 species in 118 genera and 44 families,79 native species(48.46％),67 alien species(41.10％)and 17 invasive species(10.42％)in the four riverside parks;there were significant differences in α diversity among the four riverside parks(P＜0.05);the Shannon-Wiener diversity indices of Yintan Wetland Park,Matan Wet-land Park,Marathon Theme Park and Yantan Park were 4.76,4.36,4.064 and 3.99,respectively;the Pielou even-ness indices were 0.53,0.586,0.56 and 0.54,the Patrick richness indices were 30.68,29.47,22.80 and 20.27,and the average abundances were 55.43,44.82,50.16 and 39.40,respectively.Lanzhou riverside parks are rich in auto-phytes,and the future construction of urban gardens and green spaces can be reasonably planned,the proportion of auto-phytes can be increased,and the landscape of autophytes with regional characteristics can be created according to differ-ent environments.
