- 摘要:
- 以集美区1989年与1997年的TM、2008年的ALOS遥感影像数据为基础，在RS、GIS技术支持下，运用土地利用转移矩阵与景观生态学的方法，对集美区近20 a间的土地利用及景观格局的时空动态特征进行了定量分析。结果表明：（1）林地和农用地是集美区主要的土地利用类型，二者在1989年和2008年两个时期占研究区面积比例分别为95%，68%。近20 a来，集美区土地利用快速变化，城市化过程显著。农用地面积急剧减小，而城市建设用地与城镇居民地面积则大幅度增长且趋向集中。农用地主要转化为城市建设用地、城镇居民地和农村居民地，林地面积则先减小后增加。（2）在景观水平上，集美区景观趋向破碎化，景观类型向多样化和均匀化的方向发展，景观类型的相互关系复杂化，表明区域受到人为干扰，从而使得整体景观格局的异质性越来越高。
- Abstract:
- Based on the TM and ALOS remote sensing images (1989, 1997 and 2008) of Jimei District in Xiamen City, and combining with the support of remote sensing (RS) and geographical information system (GIS), we applied some quantitative methods including transfer matrix of land use, and landscape ecology, to analyze the spatio-temporal characteristics of the land use and landscape pattern of Jimei District in last twenty years. The results showed that: (1) the main land use types were dominated by woodland and cultivated land in terms of their percentages in the study area in 1989 and 2008 were 95% and 68% respectively. During the recent two decades, this region has been experiencing rapid land use changes and urbanization processes. The area of cultivated land decreased rapidly; whereas the area of urban construction land and urban resident land increased dramatically, and their patches had been congregating. Consequently, the cultivated land was transformed into urban construction land, urban resident land and rural resident land. However, the area of woodland had firstly undergone a decreasing process, and then exhibited decreasing trends.(2) SHDI and SHEI index greatly increased, suggesting that the regional landscape became more fragmental; similarly, the relationship of landscape types showed more complex trends from 1989 to 2008. In addition, heterogeneity of the whole landscape pattern gradually increased due to the human disturbance.
