摘　　要：基于多时相中分辨率遥感数据,结合野外实地采样数据和面向对象的遥感影像分析方法,开展黄河故道地区果园信息提取,结合地形因子、海岸线分布等基础地理数据,探讨果园空间分布格局,并分析不同空间尺度下果园的聚集度特征。结果表明:黄河故道果园面积约1268.30 km^(2),其中砀山县、丰县和萧县为果园种植的主要地区;果园主要分布于高程>20~60 m、坡度≤4°的范围内的地势平坦地带,分别占果园总面积的86.84%和88.43%;果园主要分布于距离海岸线>280 km的区域内,占果园总面积的91.20%;县(区)域、10 km×10 km、5 km×5 km和1 km×1 km格网尺度下的果园种植密度呈显著空间正相关,属于空间聚集分布模式,随空间尺度降低,聚集度越高。可见黄河故道地区果园逐渐呈现出种植规模化、连片化的特征。Based on multi temporal and medium resolution remote sensing data,combined with field sampling data and object⁃oriented remote sensing image analysis methods,information extraction of orchards in the ancient canal of Yellow River was carried out.Combining basic geo⁃graphic data such as terrain factors and coastline distribution,the spatial distribution pattern of orchards was explored,and the clustering char⁃acteristics of orchards at different spatial scales were analyzed.The results showed that the area of orchards along the ancient canal of Yellow River was about 1268.30 km^(2).Dangshan County,Feng County and Xiao County were the major planting areas.Orchards were mainly distributed in flat terrain areas with an elevation of>20-60 m and a slope of≤4°,accounting for 86.84%and 88.43%of the total orchard area,respec⁃tively;orchards were mainly distributed in areas more than 280 km away from the coastline,accounting for 91.20%of the total area of orchards.The planting density of orchards at the county(district)scale,10 km×10 km,5 km×5 km and 1 km×1 km grid scale showed a significant spatial positive correlation,belonging to a spatial aggregation distribution pattern.As the spatial scale decreased,the aggregation degree in⁃creased.It could be seen that orchards in the ancient canal Yellow River were gradually showing the characteristics of large⁃scale cultivation and contiguity.
