In the choice of forest parks and scenic spots, there will be great differences in our convalescence purpose, park location and conditions. , we mainly make decisions from four aspects:
I. State of forests
Generally, the central part of the forest with an area of 50- 100 hectares or more should be selected in the forest park, preferably with obvious microclimate characteristics. If possible, we should know the microclimate indexes in different areas before planning, including air humidity, relative humidity, extreme temperature, rainfall, concentration of dust, bacteria and negative ions in the air, etc. And choose those sections that are most suitable for human comfort and recuperation to design the recuperation resort. The forest coverage rate is about 40%-70%, and the forest is divided into stable stands above middle-aged forests with mixed needles and broad leaves. Among forest tree species, pine, beech, oak and cypress are the best. More trees with sterilization function should be replanted in the planning.
Second, the terrain conditions
The sanatorium should contain as many landform units as possible, and it is best to have a large area of water, open flat land and a certain number of sparse stands. The slope is gentle but fluctuating. Ventilation for sunny airflow and water body, no pollution. There is no radioactive pollution in the rock mass.
Third, the location conditions.
As far as a park or scenic spot is concerned, sanatorium should not be located in the central scenic spot or concentrated entertainment area. Although there is a certain distance from the above-mentioned area, it should not be too far, and at the same time, the influence of other tourists on the sanatorium should be minimized.
Fourth, the area
Generally, when determining the scale of the convalescent area, the purpose of use, the stability of the forest environment and the convalescent function, the size of the park area and other social and economic conditions should be comprehensively considered. The number of forest convalescents per hectare should be controlled within 1-2.
Plant essence-natural source of health
Volatile substances secreted by plants have bactericidal and therapeutic effects. In nature, flowers, leaves, buds, roots and other organs of many plants will continuously secrete organic substances with aromatic odor during metabolism, and these substances will volatilize into the air to form gaseous substances, which have a certain recuperation effect on the human body.
Negative ion therapy-natural vitamins
Negative ions in the air are single gas molecules and negatively charged light ions formed by neutral molecules in the air through chemical reactions. Medical experiments show that air negative ions have a wide range of physiological and biochemical effects and functions, and are known as vitamins in the air. It can regulate the nerve activity of people and animals, improve human immunity, increase myocardial nutrition, enhance myocardial contractility, slow down heart rate, reduce blood lipid, relax peripheral blood vessels, regulate people's mood and behavior, and make people energetic.
Air negative ions can also stimulate the human brain, improve brain function, and directly act on the central nervous system, which has the functions of sedation, hypnosis, cough relieving, itching relieving, antiperspirant, diuresis and blood lipid lowering. According to preliminary determination, the forest oxygen bar contains 80,000-65,438+10,000 negative ions per cubic centimeter. Air negative ions can also stimulate the human brain, improve brain function, and directly act on the central nervous system, which has the functions of sedation, hypnosis, cough relieving, itching relieving, antiperspirant, diuresis and blood lipid lowering. According to preliminary determination, the forest oxygen bar contains 80,000-65,438+10,000 negative ions per cubic centimeter.
Comfortable and pleasant-natural sanatorium
Green forest is an organic sanatorium for human beings. The photosynthesis of plants in the forest makes the oxygen content in the air very rich. You can exercise while walking in the forest and enjoy a free "air bath". Inhaling fresh and clean air in air bath can improve alveolar ventilation, increase vital capacity and increase blood oxygen supply. In addition, because the smell around human life can affect people's creativity, mood, emotional performance and physical health, the aromatic substances volatilized from many plants in the forest have health care effects on people, which can help people cultivate their sentiments and cheer up their spirits.
The climate in the forest is mild, the temperature difference between day and night is small, the light in the forest is weak, the ultraviolet radiation is small, the air humidity is small, and there are many regional rains and clouds. This comfortable microclimate environment is very suitable for human survival.
Eliminate fatigue? Natural sedative
The green tone of forest has a certain regulating effect on people's psychology. It is reported that when people relax in the forest, they generally feel comfortable, relaxed and emotionally stable. According to medical investigation, in the forest, the skin temperature can be reduced by 1-2 degrees Celsius, the pulse rate can be reduced by 4-8 times per minute, and breathing is slow and even.
The forest can absorb the ultraviolet rays of the sun, weaken the stimulation to human eyes, effectively eliminate the fatigue of human eyes and psychology, and make people feel happy and comfortable.
Quiet and Leisure-Natural Silencer
Trees in the forest can eliminate some noises harmful to human health in the natural environment. According to the measurement, green plants can reduce the sound volume by a quarter through sound absorption, reflection and scattering, and the forest belt with a width of 40 meters can reduce the noise 10- 15 decibels, and the forest belt with a width of 30 meters can reduce the noise by 6-8 decibels. Because of the function of forest "natural silencer", people can rest in the forest, adjust and rest physically and psychologically.
Environmental therapy-also known as forest bath, that is, "forest environment+forest walk".
In the forest environment, we can use the five senses to feel the sound, color, touch and vitality of nature, or use the forest climate (plant essence and negative ions), topography and site effect to maintain and improve people's physical and mental health. This therapy is suitable for four seasons, and can be divided into static therapy of "sitting bath" and "sleeping bath" and dynamic therapy of "walking bath" and "sports bath", such as forest bath, outdoor yoga, forest riding and forest health trail.
This therapy can promote human metabolism, enhance resistance, eliminate tension and visual fatigue, and has definite auxiliary treatment effect on people suffering from hypertension, neurasthenia, respiratory diseases and so on.
