摘要: 对沈阳市郊区农业景观中的秋菜田斑块的大小、形状及与其它斑块或廊道的邻接情况等基本特征进行了典型调查,分析和讨论了菜田斑块在该景观中的镶嵌特征.在距城区约5km以内的近郊区,许多秋菜田斑块相互邻接,并与各类公路相邻接;距城区5~10km的中郊区,许多秋菜田斑块与玉米田斑块相邻接,并与乡村道路相邻接;在距城区10km以上的远郊区,多数秋菜田斑块被玉米田斑块所包围,并与乡村道路相邻接.

Abstract: Some typical patches of autumnal Chinese cabbage fields in the agricultural landscapes of Shenyang city suburb were investigated,and their basic features,such as areas,shapes,neighborings and connections,were recorded. Their mosaic features were also analyzed and discussed. In the region of less 5 km distance from city,many Chinese cabbage patches neighbored each other and connected to highways,while in the region of 5~10 km distance from city,they neighbored with corn patches and connected to countryside roads. In the region over 10 km distance from city,many Chinese cabbage patches are surrounded by corn patches and connected to countryside roads.
