a green tree - lined saddle hill road, cooler than a bald Road, and Nanshan in summer, four or five degrees lower than the average temperature in the city. Some people will ask whether Ji'nan's national forest city is closely related to the lives of every citizen? The answer is yes, the creation of a national forest city is inseparable from everyone living in the city.
recently, Ji'nan city has been interviewed by reporters that, after 5 years of establishment of the National Forest City, the ecological benefits, economic benefits and social benefits are in sync. The green mountain has been dyed, the spring has been protected and the sky has been purified, and more species have been attracted to the city, so that everyone has a friendly environment. Why can a forest city bring such benefits to our lives?.amp, hellip.amp; hellip; why do we bring these benefits to our lives?
retention of more water sources in Nanshan Mountain, the spring group spewing
from the city of Ji'nan along the road south along the road.
after 5 years of founding the National Forest City, Ji'nan has completed 71903 hectares of new afforestation, green corridor greening 2854.8 kilometers, the city's forest coverage from 28.9% to 35.2%, and the urban green coverage rate of 40.2%.
data show that there are more and more trees in Ji'nan. For many years, the old man living in the mountain village of the southern mountainous area said he clearly felt that there were more trees on the mountain in recent years. The responsible person in the city forestry department says that more trees can be used to maintain more water and more water can be added to the water conservation spring. In the plain area north of the Yellow River, the planting of shelterbelts can block the intrusion of wind and sand.
the southern mountainous area is the direct and indirect water supply area of the city spring group. It is an important water conservation area. The increase of the forest resources in the southern mountain area will save a lot of precipitation and infiltrate underground water to supplement the groundwater, which plays an irreplaceable role in the continuous spewing of the spring group in Ji'nan city. Over the past 5 years, 42 thousand and 200 hectares of woodland have been added in the southern mountain area by carrying out the afforestation of barren hills and returning farmland to forests. The amount of water storage of vegetation culvert per hectare can be calculated to 200 tons, and the storage capacity of forest vegetation and woodland can be added to 8 million 440 thousand tons. According to the construction cost of large reservoir in China (1.23 yuan / cubic meter), it is equivalent to saving 10 million 381 thousand yuan in water conservancy construction, and it can generate 10 million 381 thousand yuan.
more rare animals to alleviate the city's heat island effect, more rare animals are willing to come to Ji'nan / A / > low south, low concave, high summer temperature, and a furnace in Ji'nan, and the most important measure to reduce the heat island effect is greening. The relevant leaders of the Forestry Department said that through the greening of roads and rivers, the construction of ecological isolation zones, the afforestation of bare land, the greening of the urban mountains and the vertical greening, the area of urban green space has increased, and the green coverage rate of the city has been gradually increased in recent years, and the city has reduced the temperature obviously.
creating a forest city can also enrich species to protect biodiversity. In the construction of national forest cities, Ji'nan city adopted multiple tree species and coniferous and broad-leaved mixed afforestation, which not only increased the species of tree species, enriched the composition of tree species, but also formed a good forest ecosystem and enriched the biodiversity. The hidden and windshield environment of the canopy and the suitable conditions for temperature and humidity provide a good place for the animals to live. Various plants provide a rich food for the survival of the animals and make the forest a paradise for many kinds of creatures. Now, the winter Swan habitat in Ji'nan has increased from 2 to 4 from 5 years ago, and the number of swans has increased from dozens to more than 100. The national first class protection animal carving is bred in the southern mountain area, and the number of the population has increased year by year.
> [purifying air to reduce pollution]
5 years of new woodland for 5 years, the value of more oxygen production by 71 thousand and 900 hectares per year is 580 million
the increase of green trees has an important role, which is to absorb carbon dioxide through photosynthesis to release oxygen and improve oxygen release and carbon sequestration.
in accordance with the net release of 23.10 cubic meters of oxygen in 1 hectares of woodland, the newly added woodland area of Ji'nan is 71 thousand and 900 hectares (about 1 million 78 thousand and 500 mu) during the construction of the national forest city. Only 1 million 660 thousand cubic meters of oxygen can be released from the city of Ji'nan in this year, and the carbon sequestration can reach 6 million 327 thousand kg. According to the industrial oxygen production cost of 350 yuan / cubic meter, the value of oxygen released by the forest is 580 million yuan a year.
Ji'nan is one of the cities with severe air pollution. Ji'nan city combined with the construction of national forest cities and ecological garden cities, both urban and rural areas have increased afforestation, initially established the urban forest ecosystem, and played an important role in controlling air pollution and improving the air quality. According to "about 5 kilograms of plant fungicin and 68 tons of dust per hectare per hectare per year, it is equivalent to saving 80.7 yuan for the cost of dust removal; 180 kg of SO2 can be absorbed, equivalent to 99 yuan for the cost loss caused by pollution reduction, and 179.7 yuan per hectare for the annual purification of the unit forestland of two units," such a method is calculated. In the 5 years since the national forest city construction, 71 thousand and 900 hectares of new forest land have been added to the city, and the annual air purification benefit is 12 million 920 thousand yuan.
[economic benefits]
economic forest has become "rocking Qian Shu" 2 billion 400 million yuan per year. The villagers in the south mountain area said that these years have made a lot of money by planting fruit trees, cherry, walnut, apple... These fruit trees are their "rocking Qian Shu".
this is the remarkable economic benefit brought by the national urban forest construction. The forestry urban construction in Ji'nan has initially constructed the forestry industrial system. The economic benefits of forest fruit, seedlings, flowers and forest ecotourism can be directly produced. After calculation, the direct economic benefits can be added to 2 billion 400 million yuan a year. The reporter learned that the newly built timber forest is 13 thousand and 600 hectares, according to the average annual growth of 30 cubic meters per hectare and 600 yuan per cubic meter, the value of trees can reach 240 million yuan per year, and the new economic forest base is 24 thousand hectares, which can generate 30 thousand yuan per hectare per hectare in the period of the full fruit period, and can produce 720 million benefits in the year after the period of prosperous fruit. Yuan, the construction of garden greening seedlings base 12 thousand hectares, according to the annual increase of 120 thousand yuan per hectare green seedlings calculation, garden green seedlings production year of 1 billion 440 million yuan.
at present, the total output value of forestry industry in the city reaches 16 billion yuan, an increase of 430% over 2009. At the same time, through the construction of forest cities, mountain, spring, lake, river, city and forest integration, Ji'nan's urban charm has been promoted, promoting investment, developing tourism and so on, and also for the economic and social development of Ji'nan has produced greater indirect economic benefits.
> [more significant social benefits]
the employment post is more than the citizens' awareness of environmental protection
the establishment of the forest city has also brought significant social benefits, providing more jobs for the society, driving a number of people to employment and reducing social pressure. The construction of forest city has optimized the spatial distribution of Ji'nan City, improved the investment environment, and the forestry industry, such as forest products processing, forest economy and forest tourism, has been growing and expanding, providing a large number of jobs for the society.
at the same time, the national forest city construction has also enhanced the residents' ecological consciousness. The propaganda of national forest city construction and the active participation of the public, strengthen people's ecological consciousness, greening consciousness and environmental awareness, strengthen the consciousness and enthusiasm of people to build the ecological environment, and form the social consensus of "protecting nature, protecting nature and loving yourself". The growth of forest resources and the improvement of ecological environment have accelerated the adjustment of industrial structure and the development of regional economy.
