来到瑞芳镇水湳洞的「黄金瀑布」,这座位在公路旁背倚无耳茶壶山的层叠瀑布,因含有丰富的黄铁矿与硫砷铜矿,让地表呈金黄色,也是形成阴阳海的主要水源,当奔腾的瀑水流泄而下时就像是一座堆满金矿的瀑布般,耀眼动人,一幕清澈的水帘直冲金黄色的地表让人一时兴起玩水念头,不过由於这里的水质含有大量重金属物质,为了自身安全,还是三思而后行,黄金瀑布位於本山六坑口下方的自强桥畔及长仁矿区,因为早期在上游采铜矿,山泉水与雨水渗入,矿砂沉积溪床,又有菌类附着滋生、地势落差较大所以形成金黄色的瀑布奇观,黄金瀑布是金瓜石当地很有特色的一个景点,平时也很容易遇到来此地拍摄婚纱的新人。

The deep water deposition means the deposition in the area where the water depth is larger than 30 meters, in which the major sediments are coarse sand and gravel. This kind of deposition is the relic deposition formed by the Pleistocene alluvial-lacustine deposition reworked under modern channel currents actions, and ususally the Holocene acummulation lack in the deep waters. The transitional zone deposition is the deposition between the low tidal level line and the 30 meters isobath, where the sediment types is changeable and the grain sizes are gradually coarsening from the low tidal line to the deep water area. This kind of deposition is developed by the deep water eroded sediments sorting under the transitional zone current action. The different types distributed along the isobath. The tidal flat deposition is the fine sediment deposition on the tidal flat which is flo sedimentation of the silty clay under the tidal flat dynamic action and ususally developed fluid mud on the lower tidal flat. The channel mouth deposition is the deposition in the channel mouth area. According to the sediment types, it includes sand deposition where there are coarse sediments supply and silt deposition where there are only fine sediments surpport.

The results show that, under each drip irrigation treatment before the tasselling stage of spring maize, the fluctuation of average soil water content and soil matric potential at different soil depthes are comparative low under high frequency drip irrigation treatment, and the HDI can hold stable soil water content. The drip irrigation can obviously delay the effect of air temperature on the soil temperature, which was influenced by irrigation process, soil water content and crop growth stages. In addition, the irrigation frequency affects the spring maize root distribution in the soil, and the HDI improves the probability of root distribution in upper soil(0~40 cm). The yield difference of spring maize for irrigation frequency treatments is not significant under the typical field irrigation model combined irrigation with precipitation.
