【摘要】 利用3S技术对东阿拉善———西鄂尔多斯地区特有15种濒危植物的面积进行统计处理,绘制出斑块面积变化曲线图,用数字回归方法得出曲线的数学方程。然后找出各植物种斑块面积变化剧烈程度与层次分析法确定的植物优先保护序的相关关系,并进行比较分析。更多还原

【Abstract】 Applying the 3S Technology to count and deal with the area of the 15 peculiar endangered plants in the Eastern Alashan Western Erdos. We can draw change curve graph of a spot’s area and work out Mathematics Equation of the curve. Then we can figure out the violent degree of changes of the plant spot area and fix the relevant relation of the priority protection order by the Analytic Approach of the Level. Finally we can compare and analysis them.更多还原
