摘要 遥感应用在考古学中越来越普遍，但它们通常侧重于高分辨率图像和直接考古遗址检测。中等空间分辨率遥感仪器具有（接近）每天的重复间隔，但包含不太详细的光谱和空间信息，在考古学中的使用频率要低得多。然而，适度的遥感数据为考古研究提供了明显的优势，因为它们可用于在广阔的空间尺度上关联考古、生态和气候数据。为了展示这种潜力，我们使用适度的遥感数据来研究前接触晚期（约公元 1200-1600 年）景观异质性对五大湖北部本土玉米园艺传播的影响。通过分析美国国家航空航天局 (NASA) 中分辨率成像光谱仪 (MODIS) 图像，我们确定了密歇根州内陆湖泊冻融周期的差异，表明一些大型内陆湖泊产生了微气候改善，可能延长了史前玉米种植的生长季节。通过地理空间分析，我们发现墓葬和玉米种植方式优先与具有微气候的较大内陆湖泊相关。如果没有中等分辨率遥感图像提供的频繁时间成像和大空间覆盖，我们不可能发现微气候、墓葬和玉米种植之间的这些动态相互关系。
Abstract Remote sensing applications are increasingly common in archaeology but they often focus on high resolution imagery and direct archaeological site detection. Moderate spatial resolution remote sensing instruments, which have (near) daily repeat intervals, but contain less detailed spectral and spatial information, have been employed much less frequently in archaeology. However, moderate remote sensing data offer distinct advantages for archaeological research as they can be used to relate archaeological, ecological, and climactic data at vast spatial scales. To show this potential, we use moderate remote sensing data to examine the impact of landscape heterogeneity on the spread of indigenous maize horticulture in the northern Great Lakes during Late Precontact (ca. AD 1200-1600). Analyzing National Aeronautics and Space Administration (NASA) Moderate Resolution Imaging Spectroradiometer (MODIS) imagery, we identify differences in freeze/thaw cycles across inland lakes in Michigan, showing that some large inland lakes produce a microclimatic amelioration, possibly extending the growing season for prehistoric maize cultivation. Conducting geospatial analyses, we find that burial mounds and maize cultivation practices were associated preferentially with larger inland lakes with microclimates. We could not have found these dynamic interrelationships between microclimates, burial mounds, and maize cultivation if not for both the frequent temporal imaging and large spatial coverage provided by moderate resolution remote sensing imagery.
