外来入侵植物假臭草在海口各级公路分布的初步研究
为了研究外来入侵植物假臭草在海口市公路沿线的入侵情况,在海口市高速公路、国道、省道、县道四级公路沿线选取12个样地,共计108个样方进行了调查。对假臭草在不同等级道路和垂直于道路的不同距离上的分布进行了研究.结果显示各类植物91种,分属于38科。在海口市四级公路中,假臭草在高速公路和国道分布较多,在省道和县道分布较少;在同级道路垂直公路不同距离下,假臭草在垂直道路距离5m处分布较多,在1m和15m处分布较少。但是,假臭草在海口市各级公路沿线的群落特征差异均未达到显著水平。...

Bibliography: | 44-1267/S LIU Ji-feng, LIU Qiang, LI Chao-lin, WANG Heng (College of Life Science, Hainan Normal University, Haikou 571158, China) In order to study the invasion status of Eupatorium catarium along road of Haikou, 108 sampling units in 12 sample areas were investigated on side of 4 types of roads of Haikou (freeway, national road, provincial road and county road). The distribution of Eupatorium catarium in different types of roads and different distances of perpendicular to the road were surveyed. The results showed that 91 species plants of 38 families were confirmed that existed on the roadside of Haikou. In 4 types of roads in Haikou, the distribution of Eupatorium catarium was higher in the freeway and national road comparing with provincial road and county road. In the different vertical distances for the same type of road, the distribution of Eupatorium catarium was higher in the vertical distances of 5 meters for the road and lower in the vertical distances of 1 meter and 15 meters for the road.
