运用景观生态学的基本原理,借助于遥感和地理信息系统技术,分析了1975-2004年城市化过程中开封市郊区农业景观变化过程.结果表明:1975年,开封市郊区农业景观特征显著,为典型的农业景观,景观类型主要是旱地和稻田景规类型,其次为建设用地景观类型,其中旱地景观类型为优势景观类型,景观为农业、城市和自然植被组成的镶嵌体.2004年,西郊城市化特征明显,景观特征表现为密集的建筑物和道路,景观类型主要为灌溉用地和建设用地景观类型,而北郊基本上还保持郊区农业景观特征.1975-2004年,各采样区内景观格局动态明显,其中旱地、稻田、灌丛和沙地景观类型面积减少,芦苇景观类型基本消失,而道路、鱼塘、河流、绿地、建设用地和灌溉地景观类型面积增加.景观变化与城市化发展和引黄灌溉等因素密切相关,景观变化深受人类活动的影响.

Based on the remote sensing, geographic information systems technology and the basic principles of landscape ecology, we analyzed the dynamics of suburban agricultural landscape changes in Kaifeng city during the urbanization process from 1975 to 2004. The results showed that: in 1975, the agricultural landscape features were characterized by a typical suburban agricul-tural landscape pattern, and landscape types were mainly dry land and paddy fields landscape types, followed by the construction land landscape types. Landscape was composed of a mosaic of agriculture, urban and natural vegetations. In 2004, urbanization in the western suburbs was obvi-ous, with dense buildings and roads, and the main types were irrigated land and construction land landscapes. The northern suburbs basically remained the countryside agricultural landscape. How-ever, from 1975 to 2004, in the two sampling areas, landscape dynamics were both significant. The areas of dry land, paddy fields, scrub and sandy landscape type decreased, and reed land-scape types disappeared, while the area of roads, ponds, rivers, green land, construction land, irri-gated land landscapes increased. Landscape changes have a close relation with urbanization and diverting water from the Yellow River.
