| The main characteristics of Qingdao’s hydrological ecology are as follows: the seasonal precipitation is significant,the unique geomorphic features hinder the entry of rivers,the dense granite layer affects the recharge of groundwater,and the lack of vegetation makes it difficult to conserve water resources,which to a considerable extent restricts the water supply capacity of Qingdao.During the period of German occupation of Qingdao,well water was mainly used in the initial stage.With the development of the city,population growth and epidemic diseases,the traditional water supply mode could not meet the demand,so Qingdao began to carry out the planning and practice of water supply project.The water supply environment of Qingdao determines the construction scheme of Qingdao water supply project to a large extent.Therefore,on the basis of water supply environment,the German changed the traditional water supply mode of Qingdao,and successively opened up the water sources of Hai Po River and Li Chun River from near to far,continuously improving the water supply level.The water was transported to the top of the mountain for water storage by digging pipe wells to culvert groundwater,The height drop is used to deliver the water to each water using place through the distribution network,and the source protection forest is planted around the water source.However,as the colonists who invaded Chinese territory,the money the Germans paid for the water project was actually for their country’s "model colony".They never regarded Qingdao as a "leased land" to be returned to China.Therefore,the role of the German in the urban development of Qingdao should actually be an "unexpected result" rather than the original intention of the German.In the water supply project,the indigenous people of Qingdao are always the victims. |
