摘  要:
经济的快速发展加速了城市化进程,由此带了很多生态问题。通过样方法,对许昌市郊区葎草的分布情况进行了实地调查,结果表明:许昌市东郊葎草分布频度最大,高达(93.4±14.8)%,西郊葎草分布频度最小,仅为(46.6±18.6)%;公路旁、农田路旁、林地、废弃地、河流(湖泊/池塘)两岸5种生境中,河流(湖泊/池塘)两岸生境中的葎草分布频度明显较小(33.3%~66.7%);此外,葎草密度对其伴生种的数量和长势也具有显著影响,在葎草密度为2株/25 m2的样方内,伴生种密度高达73株/25 m2,且长势良好;在葎草密度为17株/25 m2并呈成群分布的样方中,其伴生种的密度仅为28株/25 m2,且多表现出营养不良。

摘  要:
Fast development of economy accelerates the process of urbanization and also brings about many ecological problems.Quadrat method was carried out to study the spatial distribution of Humulus seandens in Xuchang.The results showed that the highest frequency of Humulus seandens was recorded for(93.4±14.8) % in the eastern suburb,in contrast with the lowest frequency of(46.6±18.6)% in the eastern suburb.In the five habitats of roadside,farmland roadside,woodland,waste land and river bank,the distribution frequency was the lowest of(33.6%-66.7%) at the river bank.Moreover,the density of Humulus seandens also influenced the quantity and quality of accompanying species.When the density of Humulus seandens was 2/25 m2,the density of accompanying species was up to 73/25 m2,and they grew well.However,the density of accompanying species was only 28/25 m2 in the 17/25m2 of Humulus seandens,and most of the accompanying species lacked nutrients.
