摘要: 对沈阳市郊区秋菜田斑块与相邻接的其它景观要素的某些相互关系进行了研究,得出了在某一时段内通过一秋菜田斑块和一玉米田斑块之间界面移动的节肢动物类群和数量,观测到7个目的昆虫以平均流量10.3只·m-1·d-1通过两斑块边界相互流动,以及一乡村道路交通扬尘对秋菜田上降尘率大小和范围的影响,受道路交通影响较大的范围可达菜田内14m处.并以这些观测结果为基础,讨论了农业景观中农业生态系统镶嵌的某些原理.

Abstract: The relationship between autumnal Chinese cabbage patches and their neighboring other lanascape elements were studied in Shenyang suburb. The groups and quantities of arthropods moving through a boundary between a Chinese cabbage patch and its neighboring corn patch in certain period,were investigated and the 7 oders of arthropods moving through the boundary with an average flow of 10.3 indiviaduals穖-1-1 were observed. The changes of falling dust rates on a Chinese cabbage patch near a countryside road are analyzed. Some principles of agroecosystems in an agricultural landscape were discussed on the basis of these observation results.
