Effects of different field border grass belts on the community structure of surface arthropods
摘要
Abstract
The grass-planted strips at the edge of arable land is conducive to enhancing farmland biodiversity and ecosystem function.To investigate the effects of field margin grass strips on surface arthropods and their construction methods,artificial grass strips consisting of different plant species(two,four,six and eight plant combinations,respectively)were set up in an intensive farmland in north China as the study area,and surface arthropods were collected by the trap method and their community structure characteristics were investigated in response to different plant combinations.The results showed that the dominant taxa of surface arthropods in this study were woodlice,spiders,crickets,millipedes,among which woodlice were the most dominant arthropod taxa,accounting for 52.06%of the total number,and the number and relative abundance of woodlice in the artificially planted grass belts were higher than that in uncultivated land and farmland treatments.Compared with farmland control treatment(CKN),the artificially planted grass belts significantly increased the abundance and number of groups of surface arthropods,with those in treatments T6 and T8 significantly higher than that of T4 and T2.T6 and T8 treatments had significantly higher abundance and number of groups of surface arthropods than T4 and T2 treatments.Analyses of surface arthropod trophic functional groups revealed that the artificial planted grass strips significantly increased the number of surface arthropods in various trophic functional groups,especially detritivores and predators,with the T6 and T8 treatments having 2.9 and 3.9 times more detritivores than the wasteland treatment(CKH),5.3 and 6.9 times more detritivores than the farmland treatment CKN,respectively,while the T6 treatment had 60%and 90%more predators than the CKH and CKN treatments,respectively.Correlation analyses revealed that most of the biodiversity characteristics of surface vegetation were positively correlated with the abundance of surface arthropods and the number of groups.Among them,vegetation coverage,above-ground biomass and species were significantly and positively correlated with the number of groups of surface arthropods,while vegetation abundance was negatively correlated with the abundance of surface arthropods and vegetation coverage was not correlated with the abundance of surface arthropods.Overall,in north China,artificial grass belts significantly increased the abundance and diversity of surface arthropods,supporting more arthropods,especially detritivores and predators,which enhanced the nutrient cycling and biological pest control functions of agro-ecosystems.Among the treatments with four different artificial plant combinations,the marginal grass belts with the six plant species combination and eight plant species combination were more beneficial for the establishment of surface arthropod communities and the improvement of farmland ecosystem functions in north China.关键词
