| 摘 要： | 通过野外调查和室内统计分析,对锡林郭勒盟退化草地各植物功能群与草地螟(Loxostege sticticalis)的相关性进行了初步研究。结果表明,草地螟幼虫种群密度与一年生杂类草的相对盖度(r=0.92,P0.05)和相对生物量(r=0.94,P0.05)呈显著正相关,与相对密度呈正相关(r=0.69,P0.05);草地螟成虫种群密度与一年生杂类草的相对盖度(r=0.60,P0.05)、相对密度(r=0.69,P0.05)、相对生物量(r=0.49,P0.05)分别呈现正相关。幼虫与成虫密度均与多年生禾本科草、多年生灌木与半灌木、多年生杂类草的群落特征值呈负相关。

| Abstract: | The correlation between plant functional groups and Loxostege sticticalis population was analyzed in Xilinguole degraded grassland by field investigation and statistical analysis.The results showed that there was a positive correlation between meadow moth larvaes and relative coverage(r=0.92,P<0.05),relative density(r=0.69,P>0.05)and relative biomass of annual forbs(r=0.94,P<0.05);There was a positive correlation between meadow moth adults and relative coverage(r=0.60,P>0.05),relative density(r=0.69,P>0.05)... |
