中文摘要	半干旱坡地利用过程中,受政策和经营管理的影响,形成不同特点的利用组合类型,进而产生形态各异的景观格局。坡地农田生态系统的干扰因素较为复杂,土地利用类型不能完全反映土壤动物局地生境差异,这使得区域景观格局对土壤动物多样性的影响研究变得尤为必要。为了探究辽西半干旱区典型小流域坡地景观格局的生态效益,以辽宁省建平县白山小流域为研究区,选择7类坡地景观类型组合,对不同景观类型进行景观格局分析,用陷阱法采集近地表土壤动物,运用Pearson相关性分析法研究近地表土壤动物群落特征指标与景观指数的相互关系。结果表明,近地表土壤动物隶属于57科18目,优势种群包括步甲科和蚁科,常见种群有山蛩科、蚰蜒科、蝗科等。近地表土壤动物生物多样性指数与坡地景观指数之间具有不同程度的相关性,如土壤动物均匀度指数(J)与AREA_MN显著正相关,与LPI、PAFRAC呈现负相关;丰富度指数(E)与AREA_MN显著负相关,与PD、LPI和PRD呈现正相关。土壤动物生物量、物种数与不同景观指数之间同样存在相关性,个体数与LPI显著正相关;物种数与AREA_MN显著负相关,与PD、LPI、PAFRAC和PRD显著正相关。总体而言,坡地景观指数对近地表土壤动物群落特征指标具有明显影响,研究结果对小流域内山水林田湖草综合治理具有指导意义。
英文摘要	During the use of semi-arid sloping land, affected by policies and management, different types of use combinations are formed, which in turn produces different landscape patterns. The disturbing factors of the sloping farmland ecosystem are more complex, and the land use types cannot fully reflect the differences in the local habitats of soil animals. This makes it particularly necessary to study the influence of the regional landscape pattern on the diversity of soil animals. In order to explore the ecological benefits of the slope landscape pattern of a typical small watershed in the semi-arid area of western Liaoning, the Baishan small watershed in Jianping County, Liaoning Province was used as the research area. Seven types of slope landscape type combinations were selected, and the landscape pattern analysis of different landscape types was carried out by trap method. Near-surface soil animals, using Pearson correlation analysis method to analyze the relationship between the near-surface soil animal community characteristics and landscape indexes. The results showed that the near-surface soil animals belonged to 57 families and 18 orders. The dominant populations included Carabidae and Formicidae. Common populations included Scutidae, Schigophyllidae, Acrididae and so on. There are varying degrees of correlation between the near-surface soil animal biodiversity index and the slope landscape index. For example, the soil animal evenness index (J) was significantly and positively correlated with AREA_MN, and negatively correlated with LPI and PAFRAC; richness index (E) significantly and negatively correlated with AREA_MN, and positively correlated with PD, LPI and PRD. There is also a correlation between soil animal biomass, species number and different landscape indexes. The number of individuals was significantly and positively correlated with LPI; the number of species was significantly and negatively correlated with AREA_MN, and was significantly and positively correlated with PD, LPI, PAFRAC and PRD. In general, the sloping landscape index has a significant impact on the near-surface soil animal community characteristic indicators, and the results have guiding significance for the comprehensive management of mountains, waters, forests, fields, lakes and grasses in small watersheds in the future.
