contour-length method 中文意思是什麼
contour-length method
解釋
等高線延長法-
The calculation method of ln ( / tan # ) index widely used is the multiple flow direction algorithm developed by quinn et al. it can been seen that, in the algorithm, the contour length normal to the direction of flow flowing out the current cell is used to determine both a and tan #, and that the calculated total cumulative contributing area of downslide grid cell does not include the area of the current cell
目前普遍使用的計算該地形指數的方法為多流向法。方法中計算和tan用的均是與流出單元網格流向垂直的等高線長。另外計算下坡單元網格累積匯流面積時沒有考慮欲計算ln ( tan )值的單元網格的面積,這些是不合理的。
