What do collectors say about forests What do historians say about forests?

Collectors say forests are living fossils, historians say forests are textbook ,...

The best collectibles, because the collector, he mainly collects things, and the forest is the best place to find these collections, so the collector says that the forest is the best collection.

Collectors say that forests are the wealth of the country.

A symbol of the decline of history.

The most living collection.

The Book of Forests opposed the Brahmin monopoly of knowledge and was progressive at the time. Later, the emergence of many non-Brahmin scholars cannot be said to have nothing to do with it. The Book of the Forest opens up the first answer to many philosophical questions, marking the shift from the "ritual path" of Sanskrit to the "path of learning" of the Upanishads.

Forest resources are the general term for forest land and the forest organisms that grow in it. It is dominated by forest resources, but also includes forest and understory plants, wild animals, soil microorganisms and other natural environmental factors. Forest land includes arbor woodland, sparse forest land, shrub land, forest glade, logging land, fire land, nursery land and national planning suitable forest land.

Forests can be renewed, are renewable natural resources, and are also an intangible environmental resource and a potential "green energy". The main indicators reflecting the quantity of forest resources are forest area and forest stock. Forest resources are one of the most important resources on the earth, is the basis of biological diversity, it can not only provide a variety of valuable wood and raw materials for production and life, can provide a variety of food for human economic life, more importantly, forests can regulate the climate, maintain water and soil, prevent and mitigate natural disasters such as drought and flood, sandstorms, hailstorms; There are also functions such as purifying the air and eliminating noise; At the same time, the forest is also a natural botanical and botanical garden, feeding all kinds of birds and animals, and growing a variety of precious forest trees and medicinal materials.

Forest resources, including forests, woods, woodlands, and wildlife, plants, and microorganisms that depend on forests, woods, and woodlands for survival. Forests: including arbor and bamboo forests; Lin Mu:

including trees and bamboo; Forest land: including arbor forest land above canopy density, bamboo forest land, shrub forest land, sparse forest land, logging land, fire land, undeveloped forest land, nursery land and suitable forest land planned by the people at or above the county level. The lush forests that cover the earth are one of the most valuable "green treasures" that nature possesses.

Currently, the world's forests cover about 100 million hectares. Among them, coniferous forests account for 1 3 of the total area, and broad-leaved forests account for 2 3 of the total area. The world's forest area is now declining with population growth, about 11.3 million hectares per year.

The amount of forest resources directly indicates the conditions for the development of forestry production, the amount of forest ownership and the productivity of forests in a country or region. The indicators reflecting the quantity of forest resources mainly include: forest land, area of forest land, forest coverage, timber stock, forest growth, etc.

According to the 1985 Production Yearbook of the Food and Agriculture Organization of the United Nations, the world's forest area is about 100 million hectares, with a forest cover rate and a timber stock of 310 billion m3. China's forest area is 100 million hectares, the forest coverage rate is only, the timber stock is 100 million m3, the per capita forest area is 18 hectares, the per capita forest volume is 18, and the per capita forest stock is m3, which is equivalent to the world average of 13, which is a Shaolin country. To this end, it is necessary to expand forest resources as soon as possible and change the backward appearance of forestry.

There are many animals in the forest, and there are plants that have never been seen before.

Our ancestors first lived in the forest. They feed on gathering wild fruits, catching birds and beasts, making clothes from leaves and animal skins, and building nests on branches to make houses. The forest is the home of human beings, and it is from here that we can observe that human beings originated and developed.

To this day, forests still provide us with a variety of resources necessary for production and life. An estimated 300 million people in the world call forests their home and depend on them for their livelihoods.

The forest provides fruits, seeds, nuts, rhizomes, tubers, fungi.

In some forestry areas of Thailand, 60% of the food is taken from the forest. Animals in the forest bushes also provide people with meat and animal protein.

Timber has a wide range of uses, such as building houses, opening mines, building iron roads, building bridges, making paper, and making furniture ......Forests provide employment for millions of people. Other forest products are also rich and colorful, such as pine resin, baking gum, shellac, spices, etc., all of which are light industries.

of raw materials. China and India have been using medicinal plants for 5,000 years, and most of the world's medicinal materials are still obtained from plants and forests today. in developed countries.

1 4 The active ingredients in pharmaceutical products are derived from medicinal plants.

One of the most pressing tasks facing animals is to choose a suitable habitat. For a variety of reasons, animals must leave their original habitat to find a new one. Young animals must leave their birthplace when they grow up to avoid competition with their parents.

A habitat may be well suited for foraging, but not necessarily for breeding. Habitat is the sum of physical and biological environmental factors, including light, humidity, nesting sites, etc., all of which together constitute a special place suitable for animals to habit. It is able to provide conditions such as food and defense against predators.

Various animals choose their habitats according to their favorite environmental conditions.

Habitat selection must meet the living needs of animals, and through research on habitat selection for animals, it has been found that there are at least three selection criteria:

Able to avoid the disturbance of undesirable climates;

The size of the site is sufficient to accommodate all individuals in the group;

Keep as far away from the old nest as possible to avoid competition for food.

Animals often have a certain degree of flexibility in their habitat choices. Migratory birds tend to choose different habitats in winter and summer, and some individuals choose different habitats in different years. The extent to which this flexibility is determined by habitat selection and interspecific competition is not well understood.

The habitat chosen by the animal is able to maximize the survival and reproduction of the animal.

The place where organisms live and reproduce becomes habitats. Animals usually do not have a fixed place to live. When they are tired of activities during the day, they will find a quiet place with a better climate to rest and sleep at night.

Some animals have a smaller range of activities and will have a more fixed habitat.

In recent years, many countries have begun to study the indirect benefits of forests. Since 1971, Japan has spent three years measuring the benefits of forest answers. Japan has 25 million hectares of forests, which can store 2200 trillion tons of rainwater every year, prevent soil erosion by 5.7 billion cubic meters, inhabit 81 million birds, and produce 52 million tons of oxygen.

The total indirect benefit value of the following year was 128 billion yuan, equivalent to Japan's total budget for the whole of 1972. Finland's forests produce only 1.7 billion marks worth of timber a year, while the value of the forest's environmental insights is 5.3 billion marks. The indirect benefit value of U.S. forests is nine times the value of wood.

China's Yunnan Provincial Forestry Investigation Team, Yu Pei has calculated the forest benefits of the province, and the results show that the total value of the ecological benefits of the forest accounts for 94 of the total value of the forest, and the direct benefits account for only 6.
