| 摘 要： | 对宁夏中部干旱带压砂西瓜田杂草进行系统调查,计算该区域压砂地37种常见杂草的重要值,研究10种主要杂草的消长动态,并计测它们的生态位宽度和生态位重叠值。结果表明:蒺藜、打碗花、银灰旋花、碱蓬、刺蓬、灰绿藜、地梢瓜、山苦荬、地锦草、狗尾草等杂草的实际生态位宽度值均在0.5以上,它们是该地区草坪的主要杂草。这10种杂草间的生态位重叠值大,说明它们对环境条件的要求也比较接近。

| Abstract: | Based on the systematic investigation of weed species in watermelon fields in arid area of central Ningxia,the importance value,niche breadth and overlap of 37 species of familiar weeds were measured and population dynamics of 10 dominant weeds were explored.The results showed that Calystegia hederacea Wall,Convolvulus ammannii Desr,Suaeda glauca(Bge),Salsola pestifer A.Nelson,Cynanchum thesioides(Ereyn)K.Schum,Lxeris chinensis(Thunb),Euphorbia humifusa Willd Enum,and Setaria viridis are the top ten weeds w... |
