森林结构和生境复杂性已被广泛用于预测森林生态系统中昆虫群落的分布和丰度。我们使用野外评估和遥感植被指数作为栖息地复杂性的度量，对黄蜂组合和栖息地复杂性之间强有力的一致关系的经验推导预测进行了测试。在两个相距约70公里的森林中，对26个“高、低”复杂性地点的黄蜂样本与调查地点的多光谱录像得出的归一化植被指数（NDVIs）进行了比较。我们描述了栖息地复杂性和黄蜂群落之间强有力的明确联系，以及在粗糙和精细景观尺度上的模式。ndvi也能很好地预测生境复杂性和黄蜂群落格局。ndvi高的站点与ndvi低的站点相比，黄蜂的丰度和物种丰富度更高。利用遥感植被指数来衡量生境复杂性在生态系统建模和快速生物多样性评估方面具有重要的潜力。
Forest structure and habitat complexity have been used extensively to predict the distribution and abundance of insect assemblages in forest ecosystems.We tested empirically derived predictions of strong, consis- tent relationships between wasp assemblages and habitat complexity, using both field assessments and vegetation indices from remote sensing as measures of habitat complexity. Wasp samples from 26 paired 'high and low' complexity sites in two forests approximately 70 km apart, were compared with normalized difference vegetation indices (NDVIs) derived from multispectral videography of the survey sites.We describe a strong unequivocal link between habitat complexity and wasp communities, the patterns holding over coarse and fine landscape scales. NDVIs were also excellent predictors of habitat complexity and hence wasp community patterns. Sites with greater NDVIs consistently supported a greater abundance and species richness, and a different composition of wasps to sites with low NDVIs. Using vegetation indices from remote sensing to gauge habitat complexity has significant potential for ecosystem modelling and rapid biodiversity assessment.
