Read the schematic diagram of "South-to-North Water Transfer Project" in China and answer: (1) Please outline the spatial distribution characteristics of water resources in China. (2) Do you think water shortage is right? (1) According to the distribution law of precipitation in China, the spatial distribution characteristics of water resources in China are more in the south and less in the north, and less in the east and west.

(2) The hazards caused by water shortage in North China mainly include agricultural production reduction and factory failure, which restricts the economic development and people's poverty alleviation. At the same time, over-exploitation of groundwater destroys the ecological environment; ?

(3) Inter-basin water transfer is one of the effective ways to solve the uneven spatial distribution of water resources.

(4) As can be seen from the figure, the water conveyance trunk line B is the main part of the Eastern Route Project; River A is the Yangtze River, and C is located in Haihe River Basin.

(5) The reason for the low investment in the water conservancy project construction of this water conveyance trunk line is that the Beijing-Hangzhou Canal can be used to convey water, which reduces the engineering quantity of the eastern line. The section of this water conveyance line that can convey water by itself is section b→c;

(6) The water quality of the South-to-North Water Transfer Project is the focus of social attention. The main measures to achieve high-quality water supply in this line are as follows: all localities can effectively control the sewage discharge in the Yangtze River basin, reduce the total sewage discharge, and ensure the water quality of the water source located on the main stream of the Yangtze River; Centralized treatment of urban domestic sewage along the line to achieve discharge standards; Advocate eco-agricultural production along the line to avoid the pollution of pesticides and fertilizers to water bodies; Strengthen the publicity of water law, sewage prevention law and other laws and regulations to enhance the environmental awareness of the public and society;

(7) Besides inter-basin water transfer, measures to solve the water shortage problem in North China include water saving; Preventing and controlling water pollution; Replanting drought-tolerant crops; Desalination of seawater; Closing hillsides to facilitate afforestation, conserving water sources and so on;

(8) In order to arouse people's awareness of the crisis of fresh water resources, we can design advertising words of "water is the source of life".

So the answer is:

(1) More in the south and less in the north, less in the east and more in the west; ?

(2) Agricultural production is reduced, and factories can't produce normally, which restricts the economic development and people's poverty alleviation in this area; At the same time, over-exploitation of groundwater destroys the ecological environment; ?

(3) space (area); South-to-North Water Diversion Project; ?

(4) the eastern route; Yangtze river; Haihe river;

(5) The Beijing-Hangzhou Canal can be used to transport water, thus reducing the engineering quantity on the eastern route; b→c； ?

(6) All localities can effectively control the amount of sewage discharged in the Yangtze River basin, reduce the total amount of sewage discharged, and ensure the water quality of water sources located in the main stream of the Yangtze River; Centralized treatment of urban domestic sewage along the line to achieve discharge standards; Advocate eco-agricultural production along the line to avoid the pollution of pesticides and fertilizers to water bodies; Strengthen the publicity of water law, sewage prevention law and other laws and regulations to enhance the environmental awareness of the public and society; ?

(7) saving water; Preventing and controlling water pollution; Replanting drought-tolerant crops; Desalination of seawater; Closing hillsides to facilitate afforestation, conserving water sources and so on;

Water is the source of life.
