During the cold wave southward and the southwest warm and humid water vapor transported sufficient snowfall, planes, rockets, and smoke stoves in the northwest region went into battle to artificially increase snow, saying that it "effectively improved the ecological environment", and even the Taklamakan Desert was covered in snow.
Anyone in arid regions knows that snowfall does increase air humidity. But it's still early in spring! During these long months, the vast majority of the snow will be silently sublimated, that is, the solid state will directly become gaseous and gradually disappear, and the water that melts into the infiltrated soil is extremely small, and there is almost no infiltration into the deep underground.
The snow swept over the road melts and irrigates the small trees. Not really. The ground is permafrost, which evaporates after a few days, and the wind blows far away, and there is no return. Photo courtesy of Chai Erhong, source: Green Society Fusion Media Ocean and Wetlands.
Here, the snow on the sunny slope first sublimates and melts, evaporates and disappears, and slowly, the snow on the shady slope gradually runs into the dry air over time, blowing to the east, south, and the ocean!
I used to sweep the snow from the school meadow to the tree trough, but then I found that it didn't work, so I didn't sweep it once!
Because there is no melt into the depths of the infiltrated land, talking about improving the ecological environment is an excuse that everyone believes is true, but in fact it is "fake and empty, just a rough one", and it is in vain for a blind man to light a lamp.
There is not much melted snow water that infiltrates the shallow surface layer to freeze the soil, but after a few days because of the dry air, after the soil thaws and the capillary water evaporates, there is a white saline-alkali scourge - if it is the spring seedling unearthing season, the snow will be over: saline-alkali lumps, burn the seedlings, seal the seedlings to emerge!
Later, people summed up the lessons and covered it with sand, which has large particles and is not easy to be cemented by salt and alkali, forming a hard shell. It is easy to burn to death in the sun at noon.
It is not easy for the farming culture to move west to the north, and natural plants to be planted with artificial plants! Delicate as a moon doll. I accidentally got sick and died!
Why does the water in the arid desert region of the northwest have to penetrate deeply? Because the original ecology of arid areas is not irrigated, the roots are multiplied, and the plants are creeping and sticking to the ground to fix sandOnly those with deep roots can have the possibility of survival. The water exposed to the surface will disappear in a flash, and it is the most unreliable, and it is never intended to be relied on.
Whether it is artificial irrigation or natural precipitation, if groundwater cannot be infiltrated, then "effectively improving the ecological environment" in arid areas is an "ineffective" empty consumption that does not help, and it will evaporate in vain.
In the past, when "there was a shortage of gray and water conservancy projects were backward", once there was a flood and a landscape, we all ran to tell each other that the mountains and rivers were coming, "the mountains and rivers are coming!".Mountains and rivers are coming! The flood is coming! The flood is coming! ”。
We all know that this time the joy falls from the sky, and the joy rushes down from the heights: the surface rushes and infiltrates the underground, which will benefit the people for several years: the groundwater level will become shallow, and the groundwater quality will become sweeter.
There is no need to describe the subsequent abrupt changes in the ecological environment!
Now, human beings have invented cement cement, one after another high-walled dams, blocking the waist to cut off the lively flowing water, and nourishing the green water along the way to an abrupt end. A pool of swaying stagnant water, firmly controlled, was thinned out and dried, and in the wind and sun, it was reluctant to evaporate day and night, regardless of winter or summer, intensely and ineffectively. It's like a child with a lovely nature, suddenly locked in handcuffs and shackles, locked in a cage, and staying in a proper manner.
As a result, the precious fresh water is becoming more and more scarce because it is evaporated in vain, the water level under the dam will drop rapidly, and the underground water quality will become more and more bitter, astringent and salty because there is no dilution and desalination of fresh water from upstream rain and snow.
The original ecological salinity-alkali tolerant, drought-resistant, not afraid of exposure to the sun and cold, string roots and stems to reproduce, deep roots creeping close to the ground and sand fixing plants, no matter how deep their roots can not reach the moisture, they can only degenerate and die, the sand dunes are activated, and the wind blows the dusty sky.
Look at the Okavanke Delta in Africa in "Man and Nature", see the end of Africa's struggling, powerless and long dry season, and finally wait for the rainy season to come, reborn after the catastrophe, and a thriving beginning, the scene of this documentary is the same as ours:
Acura Life! Acura Nature!
Follow Nature! Can't man, the almighty, the primate of all things, help the floods in the arid areas to infiltrate and recharge groundwater on a larger scale, over a wider area, and on a wider scale?
Could it be that the groundwater level in arid desert areas has generally risen over a wider area, on a larger scale, and in a wider range? Will the global sweetening of groundwater quality in a larger area, a wider area, and a wider range harm anything?
Rather, it is that the reservoir is repaired to intercept the flow, and it is exposed to strong and ineffective evaporation, and it is very familiar with the road!
The lining channel does not allow leakage, and it is exposed to strong ineffective evaporation, and it is very familiar with the road!
The flood irrigation is thinned and dried ineffectively evaporated, and the light car is familiar with the road!
In recent years, "ecological environment governance" has given rise to "wetlands in arid areas, waterscape parks, rippling water in Weilu Lake, reeds, migratory birds flying, and plugging up the south of the Yangtze River", which are places where the air in arid areas is extremely dry, exposing precious fresh water, diluting and drying, and strongly ineffective evaporation of new tricks, new formats, and new formats;
Is this also a new atmosphere, a new look, and a new situation of "harmonious coexistence between man and nature"?
