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来检查可见面积。但在景观模拟中，由于其准确性尚未得到适当的详细研究，因此我们无法估计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。在本研究中，我们将尝试展示景观模拟中网格数据的基本尺度标准。考虑到每个视点的能见度差异和地形的复杂性，我们研究了网格数据的尺度与精度之间的关系。

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.
