In Yunnan, the ancients used "colorful Yunnan today" to refer to this mysterious Yunling Plateau. "Different nationalities in one mountain, different days in ten miles", on this red soil plateau, there are 26 nationalities who are constantly striving for self-improvement, showing different social and cultural forms due to different natural environments.

Yunnan is a living history museum with rich and colorful customs of various ethnic groups. Every nation's clothing, food, shelter, transportation, marriage, funeral, health, festival, ceremony, language, writing, totem, religion, taboo and aesthetics are written into a distinct cultural chain; Dongba culture of Naxi nationality, Bai culture of Dali, Beiye culture of Dai nationality and Ma Bei culture of Yi nationality are unique, profound and far-reaching ... myths, epics, songs and dances, paintings, operas and ancient music.

Yunnan is the province with the largest number of ethnic minorities in China. There are 56 nationalities in China. Besides the Han nationality, there are 25 ethnic groups with a population of over 4,000. These ethnic groups are Yi, Bai, Hani, Zhuang, Dai, Miao, Yi, Hui, Lahu, Wa, Naxi and Yao. The population of ethnic minorities in the province accounts for nearly 1/3 of the total population. As early as the clan society, there were three major ethnic groups living in Yunnan: Qiang, Pu and Yue. They were the earliest ancestors in Yunnan, and they were always called "Southwest Yi" in Qin and Han Dynasties. After several generations of continuous migration, differentiation, evolution and integration, it was not until the Ming and Qing Dynasties that the distribution and characteristics of all ethnic groups tended to be stable. Yi people are mainly distributed in northeastern Yunnan, central Yunnan and northern Yunnan. Bai people are mainly distributed in Erhai Lake and its vicinity. Zhuang and Miao nationalities are mainly distributed in the east and southeast of Yunnan. Yi, Nu, Dulong, Hani, Dai, Lahu, Wa, Jingpo, Bulang, Naxi, Tibetan, Achang and De 'ang are mainly distributed in western Yunnan, southern Yunnan and northwestern Yunnan.

The last piece of pure land in Yunnan is doomed.

China Youth Daily reported that Xiagei Hot Spring in Shangri-La County, Yunnan Province is a typical geological landscape formed by hot springs in modern times, which has great ornamental and scientific research value, especially the jet (hot air) cave in the scenic spot. However, in the process of tourism development, developers tried to turn the spray hole into a "sauna" place without knowing the geological structure and laws of the spray hole, which seriously damaged the rare tourism geological landscape. Another underground spring in this county, Tianshengqiao Caiquan, lost the natural conditions for the reappearance of Caiquan because of modern decoration. Some environmental experts are worried about this. Now, the last piece of pure land we have is becoming a boutique for tourism and leisure. All lifestyles and cultural forms different from the mainstream should serve the needs of tourism. I wonder what our nature will leave to future generations in the hands of hungry developers. To be polite, all kinds of developers are both builders and destroyers, but they can't and can't take all the profits, whether it's destroying profits or building profits.

Eupatorium adenophorum, which originated in Central America, invaded Yunnan in 1980s, and quickly spread northward, invading agricultural vegetation and encroaching on grassland and logging land. ...

"Biological invasion" triggered an ecological crisis, prompting people to analyze unpredictable nature more deeply.

Sometimes green is not necessarily a good thing.

Ping He, an engineer from the Animal Husbandry Bureau of Liangshan Yi Autonomous Prefecture, Sichuan Province, was really angry and helpless when he talked about Eupatorium adenophorum, which was everywhere. The green disaster caused by this grass to the local animal husbandry and ecological environment is even more terrible than the flood and drought disaster.

Eupatorium adenophorum was first discovered in Liangshan prefecture 1 1 years ago. Ping He recalled: "overnight, this poisonous weed suddenly appeared, along winding mountain roads, on hillsides, roofs, ditches, grasslands, farmland ... now they are everywhere."

At first, people didn't notice this strange weed that entered Liangshan area of Sichuan from far away Southeast Asia via Yunnan. Its thick and fluffy green leaves grow rapidly like dandelion flowers. Green, wouldn't it be better to have one more? But people did not expect that it was this beautiful name that brought much trouble to the local people. Because it ignored its invasion at first, in a few years, it has spread all over the mountains and plains, just like thousands of troops swept across the Shan Ye grassland in more than a dozen counties in the whole state. Wherever it went, the original plants were "squeezed away", and all the grass that cattle and sheep liked to eat disappeared, except Eupatorium adenophorum. When people found that sheep ate this grass and soon lost their hair, became sick, and the ewes became infertile and died one after another, it was too late to eradicate it.

At that time, Yunnan Province had also realized the harm of Eupatorium adenophorum, and spent more than 800,000 yuan every year to eliminate Eupatorium adenophorum, but it grew wildly and was helpless.

Eupatorium adenophorum (known locally as Eupatorium odoratum) reduced the production of more than 60,000 sheep in Liangshan Prefecture in 1996, and the loss of animal husbandry was more than 21000,000 yuan. Five years after the discovery of Eupatorium adenophorum in Yanyuan County, 152 13 sheep died. The Yi people who are still in extreme poverty are reluctant to hand over their cattle and sheep. Every family, old and young, came out to pull weeds and left them on the road to die. But people who pull weeds will have headaches and dizziness, and some are poisoned. But people are still reluctant to use pesticides, because pesticides may kill poisonous weeds, but they will hurt cattle and sheep.

In order to come up with the eradication plan, experts from Sichuan Grassland Station and Liangshan Animal Husbandry Bureau visited Yunnan, collected more than 30,000 words of data, and investigated the 430,000 mu grassland occupied by Eupatorium adenophorum in 120 towns and villages in the whole state. It was found that the crown hair of Eupatorium adenophorum fluttered with the wind and brought grass seeds into Liangshan along railways, highways and rivers. People's soles, clothes, wheels and rivers may carry the seeds of Eupatorium adenophorum. The total weight of this grass seed is less than 0.45 g, which is almost invisible to the naked eye. A clump of Eupatorium adenophorum contains 700,000 mature seeds. It can also reproduce asexually. It has strong adaptability to the environment and can grow in arid and barren slopes, walls, rock ridges and crevices. Ping He said that once a meadow has Eupatorium adenophorum, sunlight, water and fertilizer will all belong to it, and no grass can compete with it. When it entered the banana forest, the banana trees were all short 1 m, and when it entered the pepper forest, mulberry forest, pepper and cocoon, the yield was reduced by 8% that year.

In less than 10 years, this alien species covered Liangshan prefecture 15 counties, and only two counties with an altitude of more than 2500 meters were not harmed.

1997, the state government issued a special document to eliminate Eupatorium adenophorum and mobilize the cadres and masses in Quanzhou to "fight a people's war". Slogans are written and materials are distributed all over the state. Rural radio stations and state television stations, institutions and schools are talking about the harm of Eupatorium adenophorum, and all counties submit prevention and control plans. Every winter and spring, before Eupatorium adenophorum blooms, cadres and masses from all over the state go into battle to dig it out and burn it. People have come up with various weeding schemes: replacing them with artificial vegetation; Establish isolation belt to prevent its spread; Introducing Eupatorium adenophorum flies from Tibet; Planting fast-growing eucalyptus trees in disaster areas to curb the growth of poisonous weeds; Find its available value and promote its elimination. But in recent years, the results of weeding are almost invisible. Instead, the person who pulled it out fainted. When it is used as a gasket, the feet of cattle are inflamed and festered, and when it is used as fertilizer, the soil is chronically poisoned. The worst thing is that the grass grows faster and faster.

Now Eupatorium adenophorum is still advancing northward at a speed of 30 kilometers per year.

Liangshan Prefecture set itself the goal of "green mutton sheep base" in the "western development" plan, but now it has suffered the most serious ecological disaster in history.

"We will eventually come up with a solution," the animal husbandry experts still have confidence. However, the lack of research funds at present makes the grass control work stagnate.

Experts from the Chinese Academy of Sciences said that Eupatorium adenophorum is the most typical example of serious ecological crisis caused by alien species invasion. For these pests, if we have the knowledge and awareness of prevention and get rid of them when they first appear, things will not be so difficult. At present, similar problems exist in all parts of China. In the process of returning farmland to forest and grassland, returning farmland to lakes and restoring vegetation, it is even more necessary to popularize relevant knowledge, nip in the bud, choose native plants and fish suitable for the local environment, avoid single species planting and breeding, and effectively protect the local ecological environment. /Browse /92
