| 摘 要： | 利用1987年、2000年两期大比例尺彩色航空遥感影像解译结果进行空间叠加分析、转换矩阵分析和景观多样性指数分析，结果显示：呼和浩特市城市边缘区景观格局呈现出显著的走廊式和点线式变化特征，而以原城区为中心圈层式发展不显著；建筑景观的增加和农田景观的减少互为消长；经过13年的变化，边缘区仍以农田景观为基质景观，景观格局趋于复杂化、破碎化、多元化。景观格局变化中存在的突出问题表现为：城市边缘区景观格局变化缺乏统一规划指导，存在一定的盲目性，城市边缘区人工绿地景观增加偏少，边缘区湿地景观及其功能正在丧失，城市边缘区生态环境质量不佳等。

| Abstract: | Huhhot city is situated in the farming stock-raising area of with a fragile eco-environment in North China. The change of landscape structure and pattern of urban fringe not only shows the tendency of change of urban landscape ecological environment, but also indicates economic development of urban and correlated areas. So it is significant to study the dynamic changes of urban fringe in Huhhot city. Through analysis of spatial overlapping change matrix and landscape variety index, the features of landscape structure and pattern change of urban fringe were revealed. The results are as follows: 1)At patch scale, farmland is still the dominant patch type in urban fringe landscape in Huhhot city. It is observed from aerial sensing images at two time period that farmland, grassland, forest-land, orchard-land, wetland and bare-land have been decreased differently, and building up-land, greenland, water and road landscape have been increased at different degrees, in which building up-land and grassland are the most notable in the landscape patch types. Building up-land increasing and farmland decreasing also changed;2)At landscape scale,it can be described as un-matrix farmland matrix, and grassland matrix landscapes. The farmland matrix landscape has the highest landscapes diversity and evenness and the lowest dominant degree among the three landscapes. As for others, the landscape fragmentation has also increased. All landscape types are tending to be complicated, fragmented and landscape components polybasic on urban fringe in 13 years;3)Change features of passageway and spot-line are the most notable, but center-circle change is not notable. In different urban fringe regions, there are different landscape structural patterns and changing characteristics.Some problems that are appearing in the change of landscape patterns in the urban fringe include: lacking of coordination in terms of plans and policies, existing of certainly rashness in action, slow increasing in greenland, weakening of wetland function and deteriorating of eco-environment. |
