Studies on geographic distribution of wild Poa pratensis population and its community type in Yangtze,Yellow and Lancang river source region
Poa p ratensis belonged to herbage plant,which originated from Europe and northern Asia.P.p ratensis distributed widely temperature zone of northern hemisphere.P.p rantensis whose rhizomes are very strong is a kind of rhizome plant,the ability to usurp on others space is much better( Ma,2003 ).Nowadays,P.p ratensis plant was used to pioneer plant seed to grazing lands,being artificial rangeland and rebuild deteriorated grassland.But the study report on geographic distribution and plant community in Yangtze,Yellow and Lancang river(short for YYLR) source region is much less.The objective of this study was to provide scientific reference value for further study.
