Since the boundary points is discontinuous resulting from errors in inner points and interpolated results are not on the same smooth curved surface, the algebraic methods usually generates inharmonious contour lines that may intersect with each other.

分析传统绘制等雨量线方法存在的弊端:由于边界点的不连续性导致内部点误差,同时得到的插值结果也不在同一光滑曲面上,导致生成的等值线分布不协调,甚至可能出现等值线相交的错误情况。

In Taiwan area often have typhoon attracting during summer times. Typhoon brings abundant rainfall and the rainfall concentrates to the river, naturally washes out the main channel and the river high alluvion. When flood retreat, the exposed high alluvion can be widely used. Agriculture, plant and wetland, these places can increase zoology. On the other hand ,they baffle current of water flow. So this research focuses on different arrangement of flexible vegetation.

中文摘要因为台湾地区因气候关系常有台风侵袭,台风来临时带来的充沛雨量集中到河川,自然冲刷出主河道和高滩地,当洪水退去时,裸露的高滩地即可以广泛地被利用,有许多的人为开垦、种植,但是这些植生有增加动植物栖地的益处,另一方面也会产生阻碍水流的害处,所以本篇对於不同布置方式的柔性植生做流场的研究。

From the isohyetal maps, we can display the spatial distribution of rainfall caused by typhoons in Nan Shih Creek watershed.

由等雨量线图显示,南势溪集水区台风降雨之分布分别由东向西以及南向北之方向递减;台风降雨中心多发生於福山雨量站所在之区域,降雨量则由福山雨量站向东朝下盆雨量站方向递减;另外,位於本区北端之大桶山雨量所处之区域,则是另一处发生明显降雨空间变化的地区,故台风降雨在南势溪集水区内的分布具有空间变异之特性。

The increasing of soil Bray-1 phosphorus was significantly correlated to the dissolved labile phosphorus (p 0.001), and the phosphorus leaching loss under the precipitation of two-times of normal precipitation is more than 3.6 times than that of normal precipitation.

生物固形物的施用会造成表层0-10 cm土壤Bray-1磷的累积,由於土壤中Bray-1磷浓度与洗出液中溶解性反应磷的流失量有显著相关(p 0.001),且两倍雨量淋洗下洗出液中磷的流失量是正常雨量下的3.6倍,因此,生物固形物的施用仍须考量磷流失的风险。

Using many models and methods provided by GIS software, we obtain more accurate areal rainfalls of a catchment.
