The reason and countermeasure of black soil loss
The reasons for the loss of black soil mainly included the following aspects: 1. ** Cultivation method is unreasonable **: - In order to increase the area of cultivated land, slope land, gully land and forest land were reclaimed as cultivated land. During rainfall, black soil was easily washed away by water. - Over-fertilisation would destroy the nutrient structure of the soil and cause the loss of soil fertility. Long-term overdraft would lead to the exhaustion of soil fertility and the disintegration of the soil. - In order to increase production and income, over-plowing the land for two-season planting and other farming methods that broke through the carrying capacity of the black soil caused fertility decline and soil erosion. - In order to save trouble, the straw was burned, causing the black soil to lose its organic matter and the soil to become dry. 2. ** Vegetation Destruction **: - Due to the construction of houses, roads, mines, etc., cutting down, filling up, hollowing out forests, grasslands, grasslands, grasslands and other vegetation covered areas, the lack of vegetation caused the black soil to lose its protection and be susceptible to wind erosion and water erosion. - Overgrazing had eaten up the grass on the grasslands, and the lack of grass roots had caused the black soil to lack protection. 3. ** Black soil theft **: Some people secretly dig up black soil for profit, dry it, pack it, and sell it for planting flowers, raising fish, making crafts, etc. This not only makes the place where the black soil is dug into a big pit that is easy to cause floods, but also leads to the inability to grow crops and waste. There was no mention of measures to deal with the loss of black soil in the available information, but some possible measures could be proposed from the perspective of the cause: 1. ** To improve farming methods **: Rationally plan planting, avoid over-cultivation and over-ploughing, promote scientific fertilizers, reduce the damage to the soil fertility structure, and adopt reasonable straw treatment methods, such as returning straw to the field to increase soil organic matter. 2. ** Protect vegetation **: strengthen the protection of forests, grasslands, grasslands, and other vegetation, limit the damage to vegetation caused by construction projects, and rationally plan grazing areas and intensity. 3. ** Cracking down on black soil theft **: Strengthening supervision, eliminating the phenomenon of black soil theft from the source, and perfecting relevant laws and regulations to punish black soil theft.
The causes and harms of black soil loss
The reasons for the loss of black soil included natural factors and human factors, of which human factors were the main ones. Natural factors include wind erosion, water erosion, freezing and melting, etc. Human factors are as follows: - Irrational farming methods: In order to pursue high yield, long-term continuous planting, monoculture, dry farming and other unreasonable farming methods lead to a large loss of soil organic matter and nutrients, damage to soil structure, deterioration, salification and hardening. - Overuse of fertilizers and pesticides: causing soil pollution and poisoning, destroying soil biological activity and balance. - Destruction of vegetation: In order to increase income, a large number of grasslands and woodlands were converted to cultivated land, or overgrazing and logging destroyed the vegetation cover, exposing the soil to wind and rain erosion. There was also the habit of digging ridges along the slope in early agricultural production, which could drain water but accelerate the loss of black soil. - The impact of urban and industrial development: Towns and factories occupy a large amount of black land, or discharge garbage and waste water into the soil, causing soil compression and pollution, reducing soil quality and function. Harm of black soil loss: - Impact on food security: Northeast China is an important food production base. The loss of black soil reduces soil fertility and moisture, affecting crop growth, resulting in a decline in grain yield and quality, causing a large amount of grain losses every year. - Impact on water resources: Black soil is an important water conservation area. After the loss, the soil's water conservation and infiltration ability will decrease, resulting in the decline of the underground water level, the reduction of river water volume, the deterioration of water quality, causing natural disasters such as droughts, floods, soil erosion, and so on. It also affects the regional climate and temperature, intensifying the global warming trend. - Affect the balance of ecosystem: The black soil in Northeast China is an important protected area for the conservation of ecosystem. Soil erosion destroys the activity and balance of soil organisms, leading to the extinction or reduction of species, affecting the stability and function of the ecosystem. - Threatening human health and quality of life: increasing the spread and occurrence of diseases, reducing people's happiness and satisfaction.
The reason and countermeasure of blindly following the trend
The main reasons for blindly following the trend were as follows: - Lacking the ability to think independently: Some people give up their own thinking and tend to pursue the same choices as others when faced with choices. In the long run, their ability to think independently will gradually deteriorate and it will be difficult for them to make wise decisions. - Desire to integrate into the group: In interpersonal relationships, some people choose to blindly follow the trend in order to cater to the expectations of others and avoid being rejected. In this process, they gradually lose their personality. - For example, in terms of investment, buying a house, learning technology, etc., because they are not familiar with the relevant knowledge and situation, they do not know how to judge, so they follow the public's choices. The following countermeasures can be taken against blindly following the trend: - Increase self-control: In the face of temptation and impulse, learn to control your own behavior, stick to your own principles and values, and resist the impulse to blindly follow. - Increase independent thinking ability: Dare to question and challenge authority, fully consider your own actual situation and needs when making choices, and not be easily influenced by others. - In-depth study of relevant knowledge: For example, investors should systematically learn the professional knowledge of financial markets and investment funds; those who learn technology should understand the prospects of the technology. By increasing his knowledge reserves, he could improve his ability to analyze and judge independently, so as to make rational decisions. - Clear goals: Before making a decision, first determine your own goals. For example, when buying a house, you should consider your own economic situation, market environment, future planning, etc.; when learning technology, you should clearly define your learning purpose and direction to ensure that your choice is in line with your own needs, rather than blindly following others. - Formulate appropriate strategies: formulate a reasonable investment strategy based on one's own capital mobility, risk tolerance, and investment objectives. Execute decisions based on the established strategy and avoid blindly following the investment behavior of others. At the same time, when making decisions in other aspects, they should also formulate corresponding plans according to their actual situation and strictly implement them. - Maintain a calm state of mind: avoid feeling anxious after seeing others make a certain choice and achieve results, and then impulsively follow the trend. Keep calm and rational, and make a choice based on the long-term and your own reality. The novel,"The Morality of the Past", is equally exciting. Everyone is welcome to click and read it!
Control methods of black soil loss in Northeast China
The methods to control the loss of black soil in Northeast China were as follows: 1. Laws and regulations: The government should formulate and implement relevant laws and regulations to regulate and supervise the use and management of black soil, strictly enforce the regulations, and crack down on illegal mining and other acts that damage black soil. 2. ** System and mechanism **: establish and improve the mechanism and system for the protection and restoration of black soil, increase investment and support, and encourage all sectors of society to participate in the protection and restoration work. At the same time, a perfect evaluation and monitoring system should be established to discover and solve the problems and hidden dangers of the black soil in time. 3. ** Erosion gully management ** - ** Engineering measures ** - ** One ditch, one policy **: According to the principle of "one ditch, one policy", according to local conditions, set up lead wire stone cage protective measures at the head of the erosion ditch, build lead wire stone cage valley fenced and plant valley fenced in the ditch, build lead wire stone cage slope protection at the ditch bank, plant anti-erosion forest and slope protection forest at the bottom of the ditch, and establish a complete defense system from upstream to downstream. - ** Underground pipe drainage and burying and compressing **: For shallow ditches, underground pipe drainage can be arranged in the middle line of the bottom of the ditch, the lower layer is filled with compressed straw, and the upper layer is covered with topsoil to solve the problem of encroachment of erosion ditches on cultivated land. - ** Gufang dam project improvement **: The middle gully treatment can adopt the combination of rigid and flexible Gufang dam project test, that is, on the basis of retaining the rigid dam structure, the connection and drainage holes of the rock dam can be added to improve the stability and durability of the dam. - ** Biological measures **: The treatment of the lower section of the small river should pay attention to the application of biological measures. Plant suitable vegetation to stabilize the soil on the bank of the ditch, reduce water and soil erosion, and tolerate some soil distortion caused by freeze-thaw creep. 4. ** Agricultural innovation **: Change the traditional single planting mode, such as long-term wheat-corn rotation, implement rotation planting, and establish a reward mechanism to subsidize and reward farmers who have been practicing rotation planting on their own plots for many years and achieved significant results. 5. ** Public participation **: Set up a reporting system. Those who report the pollution of the black soil will be rewarded after verification. This will stimulate the enthusiasm of the public to protect the black soil and put an end to illegal activities. 6. ** Science and technology innovation **: Increase investment in technological innovation and develop new fertilizers, such as organic nitrogen fertilizers, di-amine fertilizers, and other non-polluting fertilizers, to replace traditional fertilizers and reduce the damage to black soil caused by excessive fertilizers.

Disease factors could not be ignored. Some diseases can lead to hair loss and hair loss. For example, seborheic hair loss is related to the overflow of sebaceous glands, which is related to the whole hormone level and the metabolism of the body. Baldness areata may be related to factors such as autoimmunity, genetics, emotional stress, and incrementology. It is often manifested as a sudden appearance of clear borders of patchy hair loss. Infects such as fungi and bacteria may cause damage to hair bulbs, scar formation, and cause diseases such as ringworm of the head and baldness, resulting in hair loss. Hair loss during the telogen period may be due to changes in the regulation of the hair growth cycle caused by hormones, nutrition, mental health, drugs, etc., causing a certain proportion of hair in the growth period to quickly transition to the telogen period, resulting in diffuse hair loss.
