| Popis: | 93 Watersheds rocks in Tatun volcano group is under volcano function all the year round, ground bottom magma storehouse remaining energy and rainwater form the hot liquid to exchange.insolvable gas to squirt to increase rocks to weathering effect, drenching rock will accelerate the heavy metal to drench and ooze to flow into stream, not only change pH value of the stream nearby, influence the concentration and tramsportation of heavy metal in stream.The stream is divided into a lot of basin by the watershed, each watershed of hot spring temperaturethat influenced, topographical geology and environmental condition will influence stream chemical composition. There are spout, sulphur air pore and hot spring on the after volcano group. Nanhauang-His stream and The Beihaung-His are located in the volcano function area, the stream has introduction of the sulphur gas and hot spring water of volcano, changes the environmental condition of the water body, influences the heavy metal and moves the course.There is a hot spring in area on the volcano after one The Shuang-His streams belongs to too, but the carbonic acid spring, there is less content of sulphate.Therefore, we can realize it was pH value that influenced the dissolving heavy metal to move mainly. As the season rainfall increases to make a large amount of stream propped up and flowed into the main brook, and increases the migration of the soluble heavy metal of stream.The content of silicate of function district of the last volcano does not have higher content of silicate of function district on the volcano than it is not tall on the volcano than that it is influenced that the function district of the last volcano is weathered by chemistry and drenched losing,So after dissolve but not flow to stream precipitation weathering volcano the function district the basin chemistry.Heavy metal will volcano function district in volcano function district stream high stream behind being.This research probes into (1) and analyzes in a group of main stream of volcano of Datun, the dissolving content of heavy metal of water body, compared with analysing by the topographic map, the heavy metallic element is not distributed the characteristic and topographical relation evenly. (2) Probes into metal of dissolving etc., move course among every stream, probes into weathering, stream of land influence. |
