摘要:
河岸景观幅度效应是河流生态学研究的关键问题,是河岸管理的重要依据。基于2008年2.5 m的SPOT5影像解译的景观类型图,应用缓冲带分析和景观格局指数分析,研究了辽宁太子河上游河流沿岸25 m、50 m、100m、200 m、500 m和1 000 m范围的景观幅度效应。结果表明:①河流两侧景观具有明显的幅度效应。距河道近的区域表现出具有多种景观要素的密集格局,斑块类型呈均衡化分布趋势,破碎化程度和丰富度较高;随距河道距离的增加,区域具有优势景观类型,景观中斑块形状变的规则,均匀度和丰富度降低。②景观类型分布具有区域性。草地和裸地主要分布在河道两侧50~100 m内,农田和居民地主要分布在河...
Abstract:
Extent effects in riverscape are key scientific issue in riverine ecology, and it is useful for riparian management. Based on SPOT 5 images in 2008 whose resolution is 2.5 m we got the landscape cover map through visual interpretation with minimum patch area 10 m×10 m. Buffer zone analysis and landscape index method was used in landscape analysis with gradient fro m 25 m, 50 m, 100 m, 200 m, 500 m to 1 000 m to study the extent effect of riverscape. Results showed that landscape on both sides of river has significant extent effect. The landscape is more diverse and intensive in the zones near the river, and all landscape types distributed evenly with high fragment and evenness. But there are dominant landscape elements in zones far from river channel, and the whole landscape showed pattern with regular shape and low evenness and abundance. Landscape types distribute in particular region, where grassland, bare land distribute mainly among 50 m to 100 m, while residential land and farmland distributed mainly among 100 m to 200 m. and it is far more fragmented inside 100 m than that outside 100 m. Floodplain area is small and distributes mainly among 25 m to 50 m. Zones far from river are less disturbed and rich in forest and shrubs. Landscape index on both sides of upper Taizi River in Liaoning Province,China also showed significant extent effect in class level and landscape level, but different among landscape types because of landscape formation and anthropogenic activity.
