- 摘要:
- 以烟台市1996年土地利用现状图图斑分类和地面调查为斑块属性引导，在3S技术的支持下，对2002年9月9日的ETM影像进行解译分析，选取果园总面积、斑块数、形状指数和斑块凝聚度等景观指标，对烟台市14个典型流域的果园分布格局进行了分析，揭示了各流域的果园景观的总体特征。结果表明：果园总面积（CA）、斑块数量（NP）和景观形状指数（LSI）与流域面积和流域形状指数的关联程度极为显著（在0.01水平上），关联系数分别为0.960和0.694。果园景观斑块凝聚度（COHESION）与流域面积的关联程度较显著（在0.05水平上），关联系数为0.608；果园斑块数量（NP）与流域形状指数的关联程度较显著（在0.05水平上），关联系数为0.549。各因子与流域面积及流域形状均呈正相关的线性回归关系。
- Abstract:
- Based on 3S techniques and combined with the ground review, this study analyzed the orchard landscape structure of 12 typical basins in Yantai City by using the classified principle in the land use map of 1996 to interpret the Land-sat TM image of Sep. 9, 2002.The orchard total area, number of patch, landscape shape index and patch cohesion index were calculated by using Fragstats3.3.Association and regression analysis had been employed to describe the relations mentioned indices. The results showed that: there was significant correlation (at 0.01 level) between the orchard total area, number of orchard landscape patch and orchard landscape shape index and the river basin area, and association coefficients were more than 0.960. There were also significant correlations between the river shape index and the orchard total area, orchard landscape shape index and orchard landscape cohesion index (at 0.01 level), and association coefficients were more than 0.694.There was significant correlations between orchard landscape cohesion index and river basin area (at 0.05 level), also was the number of orchard landscape patch and river shape index. The association coefficients were 0.608 and 0.549.There were positive relations between the river basin area, river shape index and the four factors.
