| 为了解大型土壤动物对不同水土治理措施的响应,于2008年5~9月,采用手拣法采集大型土壤动物,以内蒙古皇甫川流域人工松树林、人工杨树林、人工锦鸡儿灌木林、人工沙打旺草地、撂荒地和农田6种不同土地利用方式为采样地,分析了大型土壤动物群落的组成、多样性和季节动态特征。共捕获大型土壤动物1 653只,隶属于1门3纲8目34科,优势类群为鳃金龟科幼虫和蚁科成虫。不同水土治理措施下,大型土壤动物群落个体数、类群数和生物量较农田明显增加,人工杨树林增加最显著。Shannon-Wiener多样性指数(H')和Pielou均匀度指数(J)反映的大型土壤动物群落的类群配置状况,在不同水土治理样地不如农田,但群落复杂性指数(Cj)则高于农田。不同土壤动物类群对水土治理措施有不同响应特征,由于个别动物类群个体数的显著增加,不同水土治理措施有导致大型土壤动物群落结构简单化趋势。研究地区采用的各种水土治理措施对大型土壤动物群落的恢复和保护都是有益的,但适时监测和预报害虫发生以及在制定综合治理措施时考虑种植植物的多样性很有必要。 |

| Soil macrofauna were sorted by hand.The responses of soil macrofaunal community to water-soil erosion controlling methods (i.e. Pinus tabulaeformis woodland, Populus simonii woodland, Caragana intermedia shrub, Astragalus adsurgens meadow,abandoned and cropland) were investigated with emphasis on their composition,biodiversity and seasonal dynamic in Huangfuchuan Watershed,Inner Mongolia,from May to September,2008.A total of 1 653 soil macrofauna belonging to 1 phyla,3 classes,8 orders and 34 families were collected.The dominant groups were Melolothidae larvae and Formicoidae imago.Compared to farmland,the individual number,group number,and biomass of soil macrofaunal communities in other land use plots increased significantly,and it is most remarkably in Populus simonii woodland.In different land use plots,the status of animal group collocating which reflected by Shannon-Wiener index (H') and Pielou index (J) were not as good as that of in farmland,but the complexity index (Cj) of soil macrofaunal community was higher than that of in farmland.Different soil macrofauna had different response to water-soil erosion controlling methods.Because the individual number of some main groups significantly increased,the construction of soil macrofaunal communities in different land use plots had the trend of simplification.The results suggested that all water-soil erosion controlling methods are benefit to the recovery and conservation of soil macrofaunal community.But it is necessary to predict pest's dynamics in management practices,and enhance the plantation biodiversity in working-out the means of water-soil erosion controlling. |
