The history of the third year of high school, the main measures to protect and improve the ecologica

There are many main measures to protect and improve the ecological environment in ancient Chinese history, but most of them still need to be considered by period and dynasty

First, water conservancy construction can not only help agricultural irrigation, but also dredge rivers and roads and build dams to prevent soil erosion. It is divided into special irrigation works and special dredging works and fortifications to cope with the flood season.

Second, the development of urban sanitation, ancient China paid attention to urban sanitation treatment, such as water and garbage disposal, which was a system of its own in ancient times. There are special industries for garbage cleaning and sewage treatment, as well as ensuring daily water distribution, road traffic, building fire protection and other industry sectors. Each topic can be discussed in detail.

Third, the ancestors have realized the restraining role of man and nature, and man can exploit nature, but the large population will bring many problems such as environmental pollution and insufficient distribution of natural resources. In the Ming and Qing dynasties, the problem of "over-densification" appeared, and population development and insufficient distribution of natural resources had prompted many people to convert to other industries, so it can also be said that it was a development and transformation of the idea of protecting and improving the environment in ancient China.

Those who want to cause fish first pass the water, those who want to cause birds to first tree, and the water accumulation will cause fish to gather and the wood is thick.

then the bird set. "The ancients also emphasized a concept of environmental remediation, that is, the polluted environment can also be turned into a good environment through remediation. Liu An, the king of the southern Han Huai, developed the environmental protection ideas of the pre-Qin dynasty and put forward the valuable ideas of coordinating the development of agriculture, forestry, animal husbandry and fishery agriculture.

Summing up the experience of his predecessors, he said that those who hunt should not hunt all the wild beasts, should not hunt young animals, should not drain the water to catch fish, and still less should they burn the forest to hunt.

After Qin Shi Huang unified China, he began to build and destroy forests. In order to build Afang Palace, cut down the trees on the entire Shu Mountains, so there is a saying that "Shu Mountain Wu, Afang Out". The destruction and overexploitation of the environment has led to the flooding of the Yellow River many times.

During the Wei, Jin, Southern and Northern Dynasties, the economic structure of the Central Plains was adjusted, the scale of farming was reduced, and animal husbandry was expanded, which alleviated the damage to the environment during the Han and Han dynasties. During the Sui and Tang dynasties, due to the increase in population, the land resources in the south of the Yangtze River were further developed, and there were phenomena such as setting fire to the mountains, asking for fields from the mountains, and enclosing lakes to create fields. The reclamation of land from lakes and the cultivation of fields from mountains have an impact on the ecological balance.

Due to the further increase in population during the Ming and Qing dynasties, the area of wasteland reclaimed by the Qing Dynasty increased significantly. The phenomenon of enclosing lakes and cultivating farmland has increased, and the contradiction between man and land has become more and more prominent. In addition, from the Ming and Qing dynasties, the mountain and river relaxation ban system was promulgated, and the mountains and forests were opened within a certain range to solve the living problems of the people.

In the long run, this has led to the deterioration of the environment caused by the long-term exploitation and plundering of the mountainous areas, so that the fragile ecosystems of modern mountainous areas can no longer withstand serious environmental pollution, and the environmental problems in mountainous areas are becoming more and more serious.

What do you think are the historical limitations of ancient ecology to Hanyin Huice? First of all, the history of the past was not so developed, and the ideas of the ancients were not as advanced as those of the modern people, so his ecological countermeasures had many limitations.

D test question analysis: "Heaven and man win each other, and use each other", which refers to the fact that there is both opposition and unity between heaven and man. Heaven cannot interfere with the chaos and good fortune of the world, and man cannot interfere with the changes of the heavens (nature). Human beings have a certain subjective role in the natural world, and heaven also has certain restrictions on human behavior, which is a process that complements each other.

The essence of this idea of "the unity of nature and man" is to advocate the consideration of heaven, earth and man as a unified and harmonious whole, not only to pay attention to the subjective initiative of people, to transform nature and use nature, but also to respect the objective laws of nature, on the basis of protecting natural resources and the ecological environment to carry out human production activities, embodies the idea of ecological civilization, so it is in line with the theme and can be selected; "In spring and March, the mountains and forests do not climb the axe, so as to grow into the growth of plants and trees", emphasizing that the policy of fishing should not be adopted, but to give the creatures time to recuperate and maintain the balance of the ecology. "The cold and warm solar terms of heaven and earth, not for human purposes", refers to the cold temperature of the weather, which is determined by the solar terms of heaven and earth, not by human beings, which has been very clear, and does not reflect the idea of ecological civilization, so the project does not fit the topic and cannot be selected; The practice of "fishing with exhaustion, burning servals and fields" in the item is contrary to the idea of ecological civilization, so it cannot be selected. Therefore, the answer is item d.
