动物需要在不同的森林公园之间迁徙交流,在经过不同的地表时,动物迁徙的困难程度 是不一样的,如经过草地林地比较容易,而经过水域和道路时则比较困难。在不同的公园之 间构建生态廊道,保护动物的迁徙。 1. 影像分类:使用提供的训练样本进行监督分类,具体的监督分类方法任选。(10 分) 2. 创建生态廊道保护物种迁徙:(50 分) 找出从辰山植物园到阳山森林公园之间动物迁徙所花费成本最低的路线,规划部门 将在这个路径上修建生态廊道,以保护动物在两个森林公园之间迁徙。 动物在迁徙过程中,在经过不同的地表时,困难程度是不一样的,经过不同地物的 成本值见下表。 注:水域和交通用地参考已有的矢量数据,其他参考遥感影像。道路线数据的影响 范围见下表缓冲距离。
