在湿温带地区，人类活动在形成草原的规模和分布方面发挥了重要作用。根据19世纪80年代、1950年代、1980年代和2000年代的历史地图和文献，对北方千叶县9.2 × 22.3 km的土地覆盖类型和草地面积的变化进行了研究。在19世纪80年代，针叶林在土地覆盖类型中占最大面积（43.1%），草地占总面积的4.2%。然而，1880年代的文献表明，针叶林的下层可能是草的额外栖息地。因此，在这段时间内，草原物种的栖息地被认为覆盖了研究面积的54%。到1950年代，19世纪80年代的大部分草地已经变成了农田和稻田，草地面积减少到2.9%。20世纪80年代之前和期间的住宅开发导致森林和农田转化为草地，使草地面积增加到研究面积的11.6%。最后，在2000年代，草原已经下降到研究面积的6.0%，可能是由于转换为住宅区。尽管随着时间的推移发生了这些变化，但1.5%的研究区域仍然是120多年来的原始森林或草原。本文提供的空间数据对于保护规划和研究历史土地利用变化对生物多样性的影响很有用。
In wet temperate regions, human activity has played an important role in shaping the size and distribution of grasslands. We examined change in land cover type and grassland area in a 9.2 × 22.3 km area of northern Chiba Prefecture, based on historical maps and documents for four time periods (1880s, 1950s, 1980s and 2000s). In the 1880s, conifer forests occupied the largest area (43.1%) amongst land cover types and grasslands accounted for 4.2% of the total area. However, literature available from the 1880s suggests that the understorey of conifer forests may have served as additional habitat for grasses. Thus, the habitat of grassland species is suggested to have covered up to 54% of the study area during this time period. By the 1950s, much of the grassland present in the 1880s had been changed to agricultural fields and paddies and grassland area had reduced to 2.9%. Residential development prior to and during the 1980s led to the conversion of forests and agricultural fields to grassland, increasing the grassland area to 11.6% of the study area. Finally, in the 2000s, grasslands had declined to 6.0% of the study area, likely due to conversion to residential areas. Despite these changes over time, 1.5% of the study area has remained as native forest or grassland for over 120 years. The spatial data presented herein are useful for conservation planning and studying the effect of historical land use change on biodiversity.
