摘要: 
本研究是以台灣花蓮地區開發中之結晶石灰石(大理石)礦區及其附近未開
發區為試區,進行土壤試驗、水質檢測分析及泥砂生產量量測等試驗工作
,以探討該礦區開發對當地水文環境之影響,經現場調查及試驗所得結果
如下:1.土壤最終入滲率:雜林>未開發區>植生平台>碾壓採台>採台
植生(客土植 生帶)區。2.一般認為石灰石(水泥)礦區之岩層較破碎
,裂隙發達,雨水應該很容易由裂 隙排出,然經由現場入滲試驗得知,
由於採礦作業所揚起之大量粉塵,填塞在 地表裂隙中,阻塞雨水之滲入
,而使碾壓採台部分地區之最終入滲率變得很低 ,且位在殘壁下方植生
帶,因受上方掉落之岩石之夯實壓密作用,而降低土壤 之入滲能力,此
等現象對該地區之水源涵養具有負面之影響。3.由水質試驗分析可知:以
採礦區正在排放水體之濁度為最高,表示該水體中有 大量懸浮固體存在
,而沉澱池內之水體濁度與雨水相近,可見沉澱池對該礦區 確實能發揮
沉淨土砂、淨化水質之功效,因此該礦區應將地表上之水體先導入 沉澱
池內,經沉澱後再對外排放,以減少對其下游地區之自然生態環境造成負
面影響。4.泥砂生產量量測結果:採礦場之廢棄土石原堆積在峽谷內,然
隨著暴雨所產生 之大量地表逕流,被挾帶至下游地區,沉積在沉澱池附
近,經量測該地區之泥 砂淤積量,竟高達115,800立方公尺,可知廢棄
土石堆置位置為影響泥砂生產量 之重要因子。

The objective of this research was to study the hydrological
characteristicsby the limestone mining operation. The method
was carried out by waterquality, infiltration rate, and sediment
yield were surveyed. in Hualien.The results were shown as follow
: 1. The final infiltration rate of forest control is best and
then the rate of the prior explosion area, explosion zone,
operation platform and re- vegetation terrace decrease
respectively.2. Generally, the operation of limestone mining
including explosion, transport, grind-cutting. etc. decrease
the water infiltration process.3. Also, soils of mining
operation area drastically are disturbed can create horrendous
problems in water body. Water quality of run off in turbidity
and suspended solid reach frightening pollution stage, closed
to 10 thousand mS/cm and thousand ppm respectively.4.
Sedimentation treatment for the discharging water is
necessary.5. Surface mine spoils are responsible for erosion
sediment estimate at 4000 times greater then erosion in fully
stocked forest.
