利用时间序列高质量的地理信息系统数据集，研究了1979~1996年日本久谷浦湖流域景观结构的变化特征。利用FRAGSTATS软件计算景观指数来表征景观结构。我们发现，在研究期间，人工改变的景观，如人工场地和高尔夫球场，迅速增加，而同期森林和农田迅速减少。从1979年到1996年，林地减少了8.4%，其中44%变成了人工场地，37.6%变成了高尔夫球场，6.8%变成了耕地，6.4%变成了居民区，4.1%变成了城市。斑块数量的增加和平均斑块面积的减少表明，草原湖流域土地利用/覆盖变化最显著的特征是景观的破碎化。在研究期间，香农多样性指数和香农均匀度指数都显著增加，这也表明研究区的景观变得更加破碎化和异质性。这种碎片化趋势很可能会持续下去，因为近几年来，草原湖盆地的人口不断增加。
The changing characteristics of landscape structure in the Lake Kusumigaura Basin, Japan from 1979 to 1996 were investigated using time-series high-quality GIS datasets. We used FRAGSTATS software to calculate landscape indices to characterize the landscape structure. We found that human-modified landscapes, such as artificial fields and golf courses, increased rapidly during the study period, while forests and croplands decreased rapidly in the same period. From 1979 to 1996, forestland decreased by 8.4%, in which 44% turned into artificial fields, 37.6% turned into golf courses, and 6.8%, 6.4%, and 4.1%, turned into plowed fields, residential areas, and urban areas, respectively. Increased patch number and decreased mean patch area indicated that the most significant characteristic of land use/cover change in the Lake Kusumigaura Basin is the fragmentation of the landscape. Both Shannon's diversity and Shannon's evenness indices increased considerably during the study period, also suggesting the landscapes in the study area became more fragmented and heterogeneous. This fragmentation trend is most likely to continue due to the increasing population in the Lake Kusumigaura Basin in recent years.
