広域景観計画のための景観ポテンシャル評価の実証的研究

在环境影响评价中，一般采用景观模拟的方法检查可见区域。但在景观模拟中，由于其准确性还没有得到适当的详细研究，所以我们不能估计其结果的准确性和可靠性，这主要是由网格数据的规模决定的。在这项研究中，我们将试图展示网格数据尺度的基本标准在瓢虫景观模拟。考虑到各视点能见度的差异和地形的复杂性，研究了网格数据的比例尺与精度之间的关系。

The landscape simulation for checking visible area has been generally used in environmental impact assesment. But we cannnot estimate the exactess and reliblility of the result in the landscape simulation, which is mainly stipulated by scale of mesh data, because its exactness has not yet been investigated in detail appropriately. In this study, we will try to show the basic standard of scale of mesh data in the ladscape simulation. We investigated the correlation between scale of mesh data and the exactness, considering difference of visibility at each view point and the complexity of land form.
