土地荒漠化英文？6、土地荒漠化：land desertification 7、大气污染 ：air pollution 8、水体污染：water pollution 9、海洋污染：Marine pollution 10、那么，土地荒漠化英文？一起来了解一下吧。
By 2003, China desertification of land has 267.4 square kilometers, accounting for land area of 27.9%, involved in 18 provinces of 471 counties. Every year because of the direct economic losses caused desertification as 5.4 billion yuan. And every year by 3436 square km speed expansion. According to introducing, China has over 10% of the desertification of land, by 2010, China will strive to realize basic curb land desertification expansion trend. By 2020, China will achieve the whole land desertification reversal, By the year 2050, strive for to everyone who can the to-be-transformed desertification of land has been basically governance. So the reason of the problem caused desertification in China where, China what measures were taken to control? China MaWenYuan prevention-oriented expert researcher in accepting the strait sound of radio said in an interview on earth, desertification is the most common form of land degradation, known as "the earth of cancer." Earth happened about the potential scope of desertification 5170 square kilometers, accounting for approximately 40% of the world's land area, including desertification of land for 3620 million square kilometers. The potential scope of Chinese desertification happened about 330 million square kilometers, spread all over China's northeast, north and northwest regions in western China, accounting for land area of 34.6%. About eighty percent of the land has occurred different degree of desertification.
In talking to a Chinese land desertification reason, MaWenYuan researcher thinks, with the increasingly frequent sandstorm, land desertification and has attracted people's attention. Desertification expanding, in addition to climate change factor outside, main is unreasonable, mainly caused by artificial activities can be classified into "six abuse" - erected entreated, denudation, abuse of animal husbandry, excessive mining, exploitation of water resources and the illegal hunting, and is usually a variety of factors at the same time effect, make China's bonus to land desertification trend widening.
A, excessive entreated. As the population growth and short-term benefit drive, many local unplanned, outrageous for reclamation, chop Lin, and not ready to weed soil and water conservation and ecological maintenance work, causing desertification, more accelerate ecological fragile areas desertification process, "one year open pastures and two rbis quantity, three to five years become sand beams" conditions occur frequently.
Second, denudation. Because in arid areas main energy for combustion firewood, with the increase of population, residents massive lop trees, even to the shelter forest for windbreak and sand-fixation has not been immune.
Three, abuse of animal husbandry. Due to long-term off-gauge use, such as desertification area pasture ChaoZaiLv achieve 50%, in part I even up to 300%, not only cause grassland degradation, desertification area, every year by 230 million acres of degraded grassland productivity, and speed expansion than the 1950s drop about 30% ~ 50%. Grassland "1950s, 1960s didn't waist deep hip, not in the 1970s and 1980s knees ankle" ShunKouLiu image not to explain this predicament.
Four, abuse of mining. During the spring and autumn every year, a large number of personnel, gansu influx of inner etc mining with high economic value licorice, fractionation and Chinese herbal medicine, add various mining engineering area, destroying the vegetation, deforestation weeding caused great forest, the grassland desertification.
Five, the exploitation of water resources. Because China is still in the waters semi-spread way irrigation, serious waste water, while in north and northwest, plus the lack of rain water not reasonable allocation and management, river water, water shortage caused by excessive downstream, large area vegetation die, land desertification. But local residents and more excessive herding sheep, accelerate the pasture degenerate, desertification speed, currently desertification area has reached six million square kilometers, provide endless sand dust storm, Another due to the use of water, groundwater over-extraction enough, they also lead to ground vegetation die, ground vegetation so large death, land degradation.
Six, the illegal hunting. Rich economic value of wildlife habitat destruction or been because of poaching, dropped drastically, make maintaining ecological balance system of chain imbalances, indirectly caused desertification. Qinghai originally designed to eat such as rats after the saker very much, because of massive stolen catch, make mouse inundation, bedding face accumulates eating grassland, causing desertification.
As of 2003, land desertification in China has 2.674 million square kilometers, accounting for 27.9% of the total land area, covering 18 provinces of the 471 counties. Caused by desertification every year in direct economic losses amounted to more than 540 billion yuan. And the rate of annual expansion of 3,436 square kilometers. According to reports, China has 10% of the desertified land management, by 2010, China will strive to achieve the basic curb the trend of expansion of land desertification. By 2020, China will achieve the overall reversal of desertified land; to 2050, for the treatment of desertified land who can basically be governed. Then caused the causes of desertification in China where, what measures has China taken to combat? China's desertification control expert researcher Ma Wenyuan Radio Voice of the Straits in an interview that desertification is most common on Earth in the form of land degradation, known as the "Earth's cancer." Earth potential occurrence of desertification area of about 51.7 million square kilometers, accounting for 40% of global land area, of which desertification was 36.2 million square kilometers of land. The potential occurrence of desertification in China range of about 330 million square kilometers, are found in China's northwest, north and north-western region, accounting for 34.6% of land area. 80% of the land has occurred in varying degrees of desertification.
Resulting in about the causes of desertification in China, Ma Wenyuan, researchers believe that, with increasingly frequent dust storms, desertification has drawn increasing attention. The continuous expansion of desertification, in addition to climate change factors, mainly caused by irrational human activities, mainly can be summarized as "six excesses" - Ken abuse, deforestation, excessive grazing, excessive, indiscriminate exploitation of water resources and hunting, And while many factors are usually additive effect, making China's the growing trend of desertification.
First, the abuse of Ken. Because of population growth and short-term benefits, many parts of the unplanned, uncontrolled for reclamation, weed cutting forests, but also not prepared soil and water conservation and ecological maintenance, leading to desertification, but also accelerate the desertification process in ecologically fragile areas, "opened a year pasture, RBI two years the amount of sand beams become three to five years, "occurs frequently.
Second, deforestation. Because the main source of energy for the burning of arid areas of fuelwood, with the increase of population, residents cut down trees, and even used sand-fixing in the shelter were not spared.
Third, and overgrazing. Because long-term overuse, such as desertification, Grassland overload rate of 50%, in part, I even up to 300%, not only caused large-scale grassland degradation, desertification, degradation of an annual rate of expansion of two or three Qianwan Mu, and grassland productivity than five decreased by about ten years on behalf of the 30% to 50%. Prairie "waist deep without the fifties and sixties did not hip, knee seventies and eighties did not ankle," the jingle vividly illustrate this dilemma.
Fourth, excessive. Spring and autumn every year, the influx of large numbers of people in Inner Mongolia, Gansu and other exploitation of high economic value of licorice, seaweed and herbs, plus various types of large-scale deforestation, mining engineering weeding, removal of vegetation, resulting in large areas of forest, grassland desertification.
Fifth, the abuse of water resources. As the Chinese way of irrigation, flood irrigation is still a serious waste of water resources, while the Northwest and North China drought, coupled with no rational allocation of water resources and management, excessive use of water upstream of the river, causing downstream water shortages, large areas of dead vegetation, land desertification . The local residents have over-grazing sheep, but also accelerates the grassland degradation, desertification rate, the current desertification area has reached sixty thousand square kilometers, to provide endless sources of sand dust storms; other use of water resources is not enough, a lot of exploitation of groundwater has resulted in ground vegetation withered, so large areas of dead ground vegetation, land degradation.
VI hunting abuse. Economic value of wildlife-rich because of habitat destruction or by a large number of poaching, the number dropped, to maintain the ecosystem balance of the food chain imbalance, indirectly causing desertification. Such as the Qinghai vole was originally the hunting falcon eats a lot, due to a large number of stolen fishing, so that the proliferation of rodents, a large area grazed grassland, leading to desertification
The soil erosion area of 3560000 km2, more than 1 / 3 of land area, the annual
soil loss of 50 tons, about 1000000 acres of arable land, the loss of organic
matter is about 40000000 tons, the equivalent of all the country's output of
chemical fertilizer plant. Every year because of the direct economic loss of
soil erosion caused by up to about 40000000000 yuan. According to the survey of
the Sichuan provincial Party committee: appeared to accelerate the trend of
desertification caused by the astonishing speed of soil and water conservation
in China, 90 in the year to reach 2460 square kilometers. Soil erosion on the
sustainable development of economy and society of our country poses a serious
threat.
Drought and water shortage, water pollution and soil erosion makes
the further deterioration of the ecological environment in china. "The northern
rivers are dry, there are water pollution," southern rivers and lakes,
pollution, the annual direct economic losses caused by water pollution accounted
for 3.1% of GDP. Soil and water loss caused by the expansion of land
desertification, dust storms has increased. Groundwater over exploitation of
ground subsidence, cracks, seawater intrusion, the deterioration of water
quality and the formation of geological disasters in some areas, some areas of
the northwest inland for underground water level continued to decline,
desertification and desertification area continues to expand.
