Enable people to carry out forest dispose activities. First of all,beijing tour package, plants can purify the air, vacuuming dust. According to studies, green plants are the main users of CO2, but also the natural processing of oxygen. Usually 1 ha broad-leaved forest one day can be wasted one ton CO2, release 0.73 tons of oxygen. 1 day per hectare of grass can absorb 900 kg CO2, the release of 600 kilograms of oxygen. Oxygen consumption per human per day to be 0.75 kilograms, expel CO20.9 kg, the metropolis has 10 square meters per resident or 25 square meters of lawns trees and a person can exhale CO2 absorbed. Air highest allowable concentration of SO2 is 1 cubic measure of air containing 2 mg, more than the increase in the incidence people. Forest journal from 1 cubic meter of air in the digestion of 20 mg of SO2.
1 cedar can absorb 720 kg per annual of SO2; 1顷 willows preoccupy 10 kg per month SO2; privet leaves can be purified per kg SO2, up to 14 grams or more. Secondly, the plant can be reduced ruckus pollution, invest people everywhere with a sense of calm and security environment of space. According to Japan's scrutinize of the number of trees can absorb the tall frequency rumpus, especially Duanmu, calamity field cornel, China rhamnose, Forsythia, Himalayan fir the best results. Third, the forest can accommodate the temperature, to prevent the sand. It fathomed 80% to 90% of the solar radiation heat can be absorbed and reflected the crown. Leaf transpiration of trees can be part of the heat consumption, the lower the temperature 3 ~ 5 ℃. Green water conservation, air moisture can increase 14%. Especially in cities, urban green space on the reduced "heat island" a premonitory feature. According to observations, common urban and rustic areas more than the mean high temperature 1 ℃, the coldest winter nights can be higher than 4 ℃. Forest on sandy also significantly reduced role. When the air through the forest, the forest can play the role of percolate barrier, so that the wood upwind and downwind ground one meter away from the air speed approach the surface. According to the resolve in the forest area upwind and downwind, the wind speed reduced the range of tree altitude were, respectively, and 35 times 6 times. This indicates that the leeward side of the wind in the forest most obvious slowdown. Fourth, the forest will ooze a variety of serviceable pills on human elements. The alphabetical material chiefly monoterpenes, sesquiterpene and two terpenes. They have bactericidal, antibiotic, anti-inflammatory, anticancer effect, and also that the feature of promoting growth hormone secretion. Monoterpenes of which there are systems to enhance the activities of the bronchial and renal function; sesquiterpene disallow the spirit of solicitude,beijing hutong tour, adjusting visceral activities. In counting, the forest is relatively high negative ion content in general. This is deserving apt be conducted Shujian negative ground, woods, water,beijing city tour, accompanied to exposed anionic molecules is the best substance. These ventilation ions on person health is quite nice, it can be tranquility, reliability, hypnosis, pain, itching, antiperspirant, boost desire, so namely breathing and pulse rhythm steady, lower blood pressure, feelingful stability, thrust spirit, reduce fatigue, giving with great comfort, it was known as "air vitamin." In short, the forests of the colossal digit of anions and leaves, tree trunks out of the large number of fugitive mercurial phytoncid bactericidal substances combined to fashion a high-quality jungle bath can promote the health spa surroundings. Recently, some foreign savants, that the number of tree category and people cancer occurrence rates were negatively correlated. The more trees, cancer patients will be reduced. This is due to cancer and human cells the lessen in oxygen content. Forests tin not merely loosen a massive number of bactericidal substances, merely too produced a wealth of negative oxygen ions and oxygen therapy can amend the forest the oxygen content of the body cells of people, so the inhibition of cancer compartment proliferation has obvious effect. Scenic tourism amount of animals is even more obvious and affirmed. Its chief features are: ① singularity. The animals in morphology, ecology, action, forgery and migration, activities and other appearances of singular representation. Visitors to view obtainable through the curious, weird and so aesthetic. Animal is a living creature, capable to escape the migration, but also of sorts interesting "performance", attractive to visitors much more than plants. Such as invertebrates to win pretty coral, butterfly; vertebrates mix of ornamental fish, turtles, snakes, birds, mammals and so on. Including birds, mammals are the maximum momentous watch animals, they not only substantial form, observing, Kwun Kee and watch activities, but also listen to their calls, access to hearing from a kind of visual aesthetics. ② rarity. Rare picture of beasts is also acceptable. There are numerous animals in the globe of matchless, rare, or even on the brim of extinction. Such as the panda, golden monkey, tiger, horse, bison, elk, white-lipped deer, sturgeon, white-flag dolphin, alligator, brown-eared pheasant, crested ibis and so on. Because these animals have a "rare" this function, often chance the megalopolis of consideration. Beijing Baihua Mountain, Songshan, small gantry and other locations, there are many rare birds and animals, such as panther, goral, hog, brown-eared pheasant, ring-necked pheasant, etc., thereby greatly enhancing the picture of their attraction.
