摘　　要：根据某地区的分区统计数据和有关图集 ,总结设计出 4种方案的分区统计地图 ,在自行编制的认知测试软件上进行了目标搜寻测试。结果表明 ,在分区统计地图上搜寻目标时 ,视觉系统运用了平行加工策略和序列加工策略 。In this paper, four statistical maps are designed according to a set of the same data and a related atlas, and the targets searching on these statistical maps are tested with the support of the cognitive test software compiled by ourselves.The results show that when we search the target in the statistical maps, the visual system might use parallel process model and serial process model, and the mean reaction time and the correctness of the target searching are affected by the two search models. The cognitive efficiency of the designs of the four statistical maps are discussed and analyzed.
