The author:(作者)qqpublished in(发表于) 2014/6/11 10:51:02 Dug the Beijing-Tianjin Canal proponent response questions： technology is not a problem
Beijing News dispatch (reporter Deng Qi) two days ago, the Beijing Municipal Academy of social sciences and the social sciences documentation publishing house jointly issued the Beijing 2013-2014 blue book, which recommended that bore a 160 km of "Beijing-Tianjin Canal on land or sea" triggered netizens buzz, some users believe that the proposal "looks good". Yesterday, the proposal said, Director of the Beijing Municipal Academy of Social Sciences Institute of management Shi Changkui, certainly some aspects of the proposal is bold, Netizen's question is understandable.
User: looks great
2013-2014 Beijing blue book including six Department report, in Beijing public service development report in the "promoting Beijing population resources environment coordination development of public service countermeasures research" this a articles proposed, dug "Beijing Jin land sea Canal" introduced seawater, through seawater desalination for Beijing and around area provides water resources, solution Beijing water resources insufficient of dilemma, while can improved Beijing and Tianjin of atmospheric environment.
"Beijing-Tianjin Canal on land or sea" envisages songzhuang of Tongzhou, Beijing and Tianjin's Binhai Chua Jia Bao, is about 160 km, an average width of 1 km of the Canal.
Following the media reports on the recommendation triggered heated discussion, some users believe that the proposal "looks good", but not very realistic, "no pollution sources, digging canals can reduce pollution to improve the environment? ”
Editor in Chief: technology is not a problem
"Promoting the coordinated development of population, resources and environment in Beijing public service research" this article was written by Beijing Municipal Academy of social sciences, Director of the Institute of management of Shi Changkui, who is also Chief Editor of the report on the public service development in Beijing.
Yesterday, said in an interview with the Beijing News Shi Changkui, able to understand everyone's questions and concerns, and to respond to everyone's question.
Water can cause soil salinization, said Shi Changkui, this is indeed one of the suggested problems. But this is a result of the lesser of two evils because groundwater formation of geological hazards in Beijing is far higher than the extent of groundwater contamination. Instead of increasing risks of geological disasters, rather than into seawater, so against smaller, and salinization of hazards through technical treatment.
Digging canals will reduce PM2.5? Shi Changkui said, digging canals are not directly reduce PM2.5, but has positive significance for environmental improvements. Canal through effects on microclimate, air humidity can be increased by reducing urban pollution of industrial spray and dust.
Shi Changkui also believes that the dig "Beijing-Tianjin Canal on land or sea" technology is really no problem, interest is the biggest obstacle.

"A clean environment also depends on governance"
Experts said digging canals to improve the atmosphere there is a direct relationship
Peng Yingdeng urban environment management group members believe that the Department of environmental protection, cut a "Beijing-Tianjin Canal on land or sea" in improving PM2.5 does not have a direct relationship.
Peng Yingdeng said that the proposal lacks an assessment of environmental impact. Land salinization problems caused by water sinks into the ground is very serious.
According to "improve the atmosphere," said Peng Yingdeng that there is no remedy to the case, Beijing's pollution is mainly for three reasons, namely emissions from Beijing, special urban fabric and special geographical environment, the three parts of the Canal did not touch and into the sea have no fundamental impact on dust.
Peng Yingdeng said that the Beijing Academy of social sciences, as a Beijing think-tank, recommendations were adopted by the Government is very high, study needs to undergo a rigorous verification and assessment will mislead society.
College of environmental science and engineering, Beijing University Professor Xie Shaodong believes that this proposal sounds like "no logic". At present, Beijing's air quality has obviously improved compared to last year, Beijing from last year's cleaning action plans should play a role, "a clean environment also depends on the management. ”

"Canalized proposal two years ago, had offered"
Shi Changkui that feasibility study for about six months, will focus on Government and public attitudes towards the proposal
"Dig Beijing-Tianjin Canal on land or sea" proposal sparked, which mostly doubts. Why make that recommendation? What argument did earlier made? Beijing News journalist Shi Changkui the dialogue proposed in this recommendation.
The Beijing News: why would this proposal?
Shi Changkui: I have raised this point two years ago, this was considered, Beijing wants an international front row, has no outlet, and certainly not sufficient water resources. Sea is an important channel for international trade commodity collection and distribution, and is also an important crossroads for international cultural exchange. "Beijing-Tianjin Canal on land or sea" carved turn Beijing into "coastal cities". Said then that I don't notice too many people now fit the background of integration of Beijing, Tianjin and Hebei, and air pollution, it triggered a hot debate.
The Beijing News: prophase did which arguments?
Shi Changkui: feasibility study for about half a year, mostly technical experts in consulting engineering. During the consultation process, many experts have misgivings. Suggested it two years ago, was intended to report the yard, said was in the hospital for the time being on the back burner, ' in light of the water after the introduction as well as introducing water pollution problems caused by difficult to solve. Blue book on this release, I have proposed this idea, but only refers to part of, not the content of all the detail. Does have some content is bold like involved relocation of the population in the area, because it is a social science, not from the engineering point of view to prove. But the calculation is that digging such a canal, about need to relocate more than 200,000 people and region can eliminate these people on both sides of the Canal.
The Beijing News: questioned how netizens?
Shi Changkui: some people say that my brain, I think everyone's question is understandable, we worried about water pollution, security, technology, capital, personnel issues such as relocation, these worries are justified, any project is beneficial to some people, and losses to the interests of others. All of you that I am not attending, I think the "outside good monks chanting" insider over time there will be a limit, it is difficult to have innovative, outsiders will propose to advance the idea, currently cannot be achieved, along with advances in technology, the future may be able to resolve.
The Beijing News: will submit the proposal to the relevant Department?
Shi Changkui: I will not take the initiative to communicate, scholars think tank-type advice, when the route after years of arguments. Next will focus on Government and the public's attitude towards the proposal, concerned about this matter in what direction, I, as a person who write recommendations, advice that is my duty, I want to suggest to the letter.

"Beijing-Tianjin Canal on land or sea" functions:
1, through the Canal into the sea through desalination of sea water for Beijing and its surrounding areas through provision of water resources, shortage of water resources in Beijing;
2, through the Canal into the water, improving the atmosphere in Beijing and Tianjin, in order to create a livable city creates conditions;
3, through the Canal shipping, open direct sea Beijing, shipping industry development in Beijing and the surrounding area;
