中文摘要 | 花蓮縣壽豐溪上游集水區內石灰石礦場土堆理化性質經由場區 (A 區)、捨石場坡面 (B區)及鄰近溪床坡趾處 (C區)採樣分析結果得知該區城土壤 反應,因受石灰石礦場影響而呈中性至弱鹼性反應,有機質含量普遍偏低,含石 量甚多,透水性良好,氮、鉀元素含量缺乏,值得爾後從事綠化植生復育參考; 由團粒穩定度、分散率、鈉吸著比及交換性鈉百分率了解該處土壤不易絮聚,雨 水逕流校易引發士壤沖蝕。又因該區城土垃含有少量膨脹性粘土礦物,為日後工 程作業時須謹慎處理。 |
英文摘要 | Soil physicochemical properties of Quarries located at up Sou-fong stream watershed,sampling from mining area (site A), slopeland of spoiled area (site B) and down slopeland of wildstream (site C). Results of analysis indicate that the reactions of soil are from neutral to mildlyalkaline, and organic matter contents are low. In general, amount of gravel contents andinfiltration of water are well, but the nutrients of nitrogen and potassium are deficient, so we mustput it in mind when searching for biological recreations. Consulting from the properties ofaggregate stabilities, dispersion ratio, sodium absorption ratio and exchangeable sodiumpercentage, we know that the soils of this area are easily dispersed by water,and the fine particlesmay be eroded easily. And from X-ray diffraction analysis for clay minerals, we find the soilshave some swelling constituents@vermiculite, that should be cautioned as engineering's operationis performed. |
