| The fever, the fever, burns long triangle over ten thousand Chinese acres fertile farmlands changes a derelict land |
|
The land is the national precious non-renewable resources, but the inch of lang and gold long triangle area many city county actually exists violates the country agrarian policy burn solid to mount the cob brick massively the situation. The land is farmer's lifeblood, is " three agriculture " the question foundation, however under the economic interest enticement, some places and for the temporary benefit, the sparing no sacrifice descendant descendants' land gains this generation of person's temporary benefit personally. Statistics indicated that cut off in 2004 only Zhejiang " the baked clay bricks and tiles " to cause 80,000 Chinese acre grain field to turn the sores all over the eye derelict land.
“baked clay bricks and tiles " still, fertile farmland beautiful scene no longer
In the achievement world one of most ancient building materials, the solid loam brick is called as " the baked clay bricks and tiles ", since long in our country by massive productions and widespread use, however its burn is actually take damages the land resource, the destruction ecological environment as the price. The long triangle area's natural resource is not originally abundant, the architecture industry and building materials industry development rapid very, the burn solid loam brick initiates a series of environment resources question manifests in this area is obvious.
Planted the mulberry to raise silkworms once was the Zhejiang Hang-Jia-Hu area general farmer's road of becoming rich, at the present are many human actually to be able not but to give up this profession, the reason is because of there numerous make bricks factory for many years intemperate dredge bakeing bricks, destroyed the local land resource and the ecological environment. Thus it can be seen, “baked clay bricks and tiles " the harm cannot look down upon.
According to the related department reckoning, constructs 10,000 square meter multi-layered housing to need 2,000,000 to mount the cob brick, will produce these to mount the cob brick to consume the land 3.3 Chinese acres. Only take Shanghai as the example, if, according to the Shanghai yearly average housing completed residential areas 11,000,000 square meters computations, therefore excavates every year the land amounts to 3200 Chinese acres, meanwhile some 216,000 ton sign coal is consumed, discharges the massive carbon dioxide and the sulphur dioxide gas.
“the baked clay bricks and tiles " gradually draws back the historical arena
The State Council has forwarded departments and so on original National Building materials Bureau since 1992 "about To speed up Wall Material Innovation And Promoted Energy conservation Construction Opinion Notice", our country wall material innovation has made the positive progress. The long triangle area to the new wall material's promoted start early, has appeared including the tax preference policy; Sets up the new wall material special fund a series of support policy, has obtained the good result.
From 1991, Shanghai starts to carry on take the festival, the energy conservation, the environmental protection innovates as the objective wall material, by the end of 2004, the whole city artificial brick and so on non-clay class new wall material utilization ratio has surpassed 68%, the accumulation saves plants crops 33,000 Chinese acres, coal economized 2,020,000 tons, utilization of waste 15,450,000 tons. By the end of 2004, Jiangsu Province solid mounted the cob brick already by 1990 50,000,000,000 drops to 12,000,000,000 sign bricks, the new wall material output 745,000,000 grew from 1990 to 30,100,000,000 sign bricks, the wall material innovation saves every year plants crops 50,000 Chinese acres, conserves energy 2,200,000 ton sign coals, comprehensive utilization waste residue 15,000,000 tons.
Estimated according to the State Economic and Trade Commission resource conservation and the comprehensive utilization department that by the end of 2005, the national new wall material output will achieve 300,000,000,000, thus occupies above wall material ultimate output 40%, medium cities achieve above 50%, the big or media-sized cities achieve above 60%, the urban district achieves above 80%. Meanwhile, besides June 30, 2003 before forbids to use the solid loam brick 208 cities, all provincial capital city before 2005 also comprehensively will forbid to use the solid loam brick. The other day, the Council General Office issued the notice, the request further advances the wall material innovation and the promoted energy conservation construction. Statement: By the end of 2010, all cities forbid to use the solid loam brick, “25 " period our country national economy, fast, the healthy development and the consumer market demand's change, the resident housing will still be the consumption hot spot continually. The Department concerned forecast that our country entire society house year completed residential areas will amount to 18 - 2,000,000,000 square meters, the architecture industry increase in value yearly average above the approximately 700,000,000,000 Yuan, this will bring the broad market prospect for the new wall material's development.
