Abstract
The present invention relates to once more utilization of fresh water resource of estuary of river and long-distance transmission by means of ocean to raise the economic performance of fresh water. Said invention is specially suitable for long-distance transmission of lots of fresh water of global great river, for example it can supply fresh water for desert area, and can improve the ecological environment of said area, and features small investment, convenient construction and low cost.
Description
The freshwater resources that the present invention relates to the rivers estuary utilize once more, the method that the fresh water of rivers estuary is carried at a distance by the ocean.
As everyone knows, the earth surface ocean accounts for 71%, land accounts for 29%, but human freshwater resources and rareness thereof of depending on for existence, accounts for that 70% freshwater resources concentrate on the South Pole and area, Greenland is difficult to utilize.Along with the increase of global population, expanding economy, freshwater resources are deficient day by day, the minimizing of whole world tree and grass coverage, the desertification degree further enlarges, and urban water supply day is becoming tight, the ecological environment in the whole world is worsened day by day, had influence on the sustainable development of global economy.From another angle analysis, the last region-by-region freshwater resources of the earth are still very abundant, as basin, South America Amazon, the basin, the Congo in Africa, the Yangtze river basin in Asia etc.Because these regional freshwater resources are abundant, a large amount of fresh water also do not make full use of, and but flow into the ocean endlessly.
When people stepped into 21 century, people recognized to have only freshwater resources are increased income and throttling, improve the utilization rate of freshwater resources, could improve the ecological environment in the whole world, could keep the global economy sustainable development.
At present the method for countries in the world regulating pondage normally: from the upper, middle and lower reaches of the abundant regional rivers of freshwater resources, extract certain fresh water amount by pumping plant, be transported to the area that lacks fresh water from land after pressurizeing.This method has following deficiency: 1, regulating pondage generally can not be too big, because when extracting rivers middle and upper reaches fresh water, will have influence on the output of downstream river.2, lay a considerable amount of sloots or pipeline on land, can be subjected to the restriction of geographical environment, as the restriction of mountains and rivers, rivers cities and towns, industrial facility.3, the sloot of being built, pipeline, unavoidably occupy the land resources in a large amount of farmlands, so construction cost is higher.
In view of the deficiency of said method, task of the present invention proposes a kind of method that the fresh water of rivers estuary is utilized once more, and by the ocean fresh water of rivers estuary is carried out long distance and carry, and has improved the economy that freshwater resources use.
A large amount of fresh water that the present invention is specially adapted to global great rivers mouth carry out the long distance conveying, and it is few to have investment cost, and it is convenient to build, the characteristics that cost is low.
Advantage of the present invention is: the pipeline that is laid in the ocean does not take the land resources that the mankind depend on for existence; Secondly, the pipeline of being laid in the ocean can be considered the deadweight of fresh water in the pipeline, even lay huge bore pipeline because external and internal pressure is equal substantially, the wall thickness of pipeline can design very thinly, so the cost of pipeline material is significantly less than the cost of land tubing; Once more, the fresh water pipeline that is laid in the ocean generally is laid on the continental shelf, and the depth of water is more shallow, and construction cost is lower.Four, the long distance of fresh water conveying in the pipeline in the ocean need not energy consumption.
Typical example as: river mouth, the Congo by Africa and the river mouth, the Amazon of South America draw gets a certain proportion of fresh water, if get the 10-20% that above-mentioned river on average flows into the ocean fresh water amount for many years by drawing, can obtain about 1600 billion cubic meters of year estuary and 3500 billion cubic meter fresh water respectively, lay conduit pipe from the continental shelf in seabed, the Atlantic Ocean, west coast of Africa respectively, cross the conduit pipe in seabed, the Atlantic Ocean with laying from the river mouth, the Amazon of South America, fresh water is carried in area, African the Sahara and Arabic area to 7,700,000 square kilometres of areas, build two parallel artificial main stems from West to East in the area, Sahara Desert, and build river course or the pipe network that connects two artificial main stems: draw the seabed conduit pipe of getting fresh water from river mouth, the Amazon and land from Morocco's south seashore, the artificial main stem of building is by way of Algeria, Libya, Egyptian, through Sinai, enter the Palestine in Arabic area again, Israel, Jordan, finally deliver into the Saudi Arabia area in the Arabia Peninsula; Draw the seabed conduit pipe of getting fresh water from river mouth, the Congo and land from Mauritanian seashore, the artificial main stem of construction is by way of Mali, the Niger, Chad, turn to north within the border in the Sudan, and domestic and another artificial main stem converges in Egypt.Because area, the Sahara physical features is comparatively smooth, generally carries fresh water from stream mode, as long as increase a small amount of force feed pumping plant.The present invention can thoroughly change the ecological environment in area, Sahara Desert and Arabic area, and above-mentioned area is transformed into forest, grassland and farmland, also helps the exploitation of underground mine resource.Be benefited area in ten thousand square kilometres of scopes of 400-500, thereby can obtain huge economic benefit and social benefit.
And for example drawing and get the about 1200-1800 billion cubic meter of Chinese the Changjiang river year estuary fresh water, is that main irrigating gate draws and gets fresh water from the Changjiang river estuary of Chongming Island north side, by being laid on seabed, Huanghai Sea continental shelf conduit pipe, supplies water to Beijing, Tianjin after entering marine site, the Bohai Sea.The Huanghai Sea continental shelf depth of water is more shallow, and pipeline generally is laid in the sea water advanced scope of 60-80 rice.Its main fresh water amount seashore between Qinhuangdao and Jinzhou City lands, cross by the cascade pumping station force feed and to exert Shandong youngster's Tiger Mountain, after entering Nei Mongol Plateau, fresh water is carried in main master stream westwards, north side, the Yinshan Mountains by way of the Yellow River river bend enters the north, Gansu Province, Bosten until Xinjiang, and replenish the water source to exhausted day by day Tarimhe River; And can carry the branch of fresh water to pass tower lattice desert, khoum to Xinjiang, along the Ruoqiang in southern side, Tarim Basin and the end, the people live in plenty and a line such as field, Yecheng is carried fresh water.The Takla Makan Desert that takes up an area of 330,000 square kilometres is transformed into forest, grassland and farmland; By the Altun mountain pass again through the cascade pumping station force feed, the desert area of carrying fresh water to enter the Caidamu Basin from the northwestward, Qinghai Province, another road fresh water northwards along the Turpan Basin west side through Urumchi, until the Junggar Basin, to support the exploitation of mineral reserve such as these regional oil, natural gas.Carry the fresh water amount in year 600-800 billion cubic meter scope to Xinjiang.Effectively like this improved the situation that these areas, the Chinese north seriously lack fresh water.Because these areas belong to Nei Mongol Plateau, physical features is comparatively smooth, and the underground mine resource is very abundant, the existing mineral reserve such as oil, natural gas of developing.These regional physical features are generally in the altitude range of height above sea level 1000-2000 rice, the river rareness, therefore by the excavation river course, carry fresh water from stream mode, as long as increase a small amount of force feed pumping plant, under the less fund condition of input ratio, can obtain its great economic benefit and social benefit, strong support transfering natural gas from the west to the east and development of the West Regions, increase the cultivated area of China greatly.If draw the fresh water of getting coastal area of southeastern China such as the Zhujiang River, the Min River, the Oujiang River rivers estuary again, can transform the Desert of Gobi that comprises People's Republic of Mongolia like this.The benefited area that fresh water is carried is in ten thousand square kilometres of scopes of 150-250.
Suggestion is built two and is striden the Bohai Haixia and stride the highway and the railway major paths of Liaodong Wan in the Bohai Sea: stride Bohai Haixia highway and railway bridge building in the Lvshun city in Liaoning Province, through the island, mausoleum of Shandong Province archipelago to Penglai City; Stride the highway of Liaodong Wan and a large amount of silts that the railway major path utilizes deposition in the bay, build between the Changxing Island in Qinhuangdao, Hebei province and Liaodong Peninsula, and below two gulf over strait passages, having can be by the navigation ability of 20-30 ton boats and ships.Shorten transportation range greatly, improved transport capacity along Bohai Sea Area, strong promotion the ring economic zone, the Bohai Sea development.
Liaodong Wan is set up in suggestion becomes open fresh water storage areas, promptly stores fresh water at dry year.
The present invention show for typical example: the fresh water by the rivers estuary utilizes once more, these regional ecological environments have been changed effectively, above-mentioned area is transformed into forest, grassland and farmland, guaranteed Africa and Asia sustainable economic development, had profound significance to the improvement of world's ecological environment with to development of world economy.
