Ecological environment good animals to home! The ecological restoration of Ji'nan mountain is remarkable
Shun Net - Ji'nan daily author: Han Xiao Peng
this year, a lot of people who go to the Mountain Park leisure sightseeing have found that the lonely mountains are getting more and more lively in the past. Summer insects, frogs, flying birds, winter pheasants, squirrels, hedgehog.Amp; hellip.amp; hellip rarely seen little animals in the past more and more. The reproduction of animal and plant population is a significant sign of the gradual restoration of mountain ecosystem. It proves that the mountain ecosystem in Ji'nan city is developing towards a good direction.
it is rare to see
Ji'nan is a mountainous city from time to time. After more than 20 mountain parks have been opened in succession, it has become a daily habit for many citizens to get closer to the mountain.
Li Ming, 72 years old, goes to Buddha Hill almost every day. A few years ago, if he met a hedgehog in the mountains, he would excitedly talk to his neighbors for a while. This year, it has become a common thing to climb mountains to meet small animals. This summer, I climbed a mountain with my partner. I often heard frog calls at the foot of the mountain. It was very rare. When we got up early, there were many birds drinking in the pond. We secretly took the cell phone behind. Li Ming told reporters that it is winter now and there are many small animals in the woods. Recently, I often heard a pheasant on the mountain. Last week, I saw a small squirrel jumping up and down on the tree branches.
these frequent infested animals make the mountain climbing tour of the citizens more interesting and much more talked about. Liu Jingmei, a citizen living in Huan Shan Road, said that living in the city, everyone was used to having flowers and trees on the mountain, but there were no wild animals. It is a legend to mention what animals are on the mountain in the early years. I'm still wondering how these animals came.
in 2014, the city started the construction of the mountain park for three years. By the end of this year, at least 26 mountain parks will be built and open. The city garden Bureau has built many mountain parks, such as the Buddha Hui mountain, the tiger mountain, the Pingdingshan, the gourd top, the Golden Chicken ridge, the drum tower peak and so on. The project group also noticed the change of the mountain.
the increase of small animals is closely related to the density of trees and water on the mountain. The most important thing is water. Wang Chunhong, a senior engineer in the city forest farm, said that when building a mountain park, a large number of seedlings and ground are planted by the green mountain to build a sponge to block the rain, which is the two foundation for each park. The reconstructed mountain can hold up 85% of the rainwater. The rainwater collected during the rainy season collects into the permeable ponds and cistern for irrigation, fire prevention, and also facilitates the drinking of animals. Many reservoirs have water now.
trees become denser, and all kinds of animals have plenty of food. Animals can live in the mountains if they eat, drink and have places to hide. Then, slowly expand the population until the colony settles.
plant population expansion and acceleration
plant populations are also changing. The golden peak has the largest wild species of Ji'nan. During the process of building a mountain park, the staff specially protected the population of the tree and replanted some of the trees to form a stable plant population. In this way, exotic species are hard to invade, and the genus can grow steadily.
after large-scale greening, the original sparse forest became dense forest, and shrubs were planted under the forest. The soil conditions were gradually improved, and different kinds of land were grown. During the greening process, there are also some plant seeds in the backfilled soil. As a result, the original extinct ground appeared again, and the speed of its original multiplication was speeded up.
from 2014, the city forest farm planted the seed of chrysanthemum artificially in the mountain and other mountains. After the soil nutrition and water content increased, the expansion speed of the chrysanthemum was obviously accelerated. Artificial sowing of wild chrysanthemum has twenty thousand square meters, coupled with natural propagation over the past two years, the total number of wild chrysanthemum also has tens of thousands of square meters. Wang Chunhong said she and her colleagues also observed that the number of wild mulberry leaves was also increasing.
soil and water can retain
propagation of flora and fauna is a significant sign of mountain ecosystem restoration. There are many changes in the mountain itself.
before the building of a mountain park, the rainy season hit a heavy rain, the rain washed from the top of the hill, the gravel was washed down, and the rainwater rushed to the foot of the mountain until the rainwater flowing into the municipal road was yellow soup. After a long period of soil erosion, mountains will be washed out of ugly valley. In addition, in the rainy season, mountains are prone to landslides and other geological problems.
this year, after the mountain park transformation and the construction of the sponge City, not only did no landslides or landslides occurred, but the rainwater washed to the foot of the mountain was clear. It is not a torrential rain, and rainwater seldom flows into the municipal road again.
in the rainy season, after the mountain soil saturated, and then the rain, the mountains will appear streams, falls, waterfalls and other landscapes, in the hot summer to become a clear water. Statistics show that after the same rainwater level has been rebuilt through mountain parks and sponge cities, the existence of waterscape in the mountains can at least double.
the ecological restoration time of the mountain is shorter
the relevant person in charge of the city garden Bureau said that if there is no human intervention, the ecological restoration by animals and plants alone, a population from being destroyed to a slow recovery, to a stable development, may take hundreds of years or even hundreds of years. The time needed for artificial scientific means can be greatly reduced.
according to the introduction, the emergence and growth of the elf in the mountain park is only the beginning of ecological restoration. The food chain of animals will gradually grow longer, and long-term citizens will see more wild animals appearing in forests. When you meet an animal, people should not be disturbed.
as we all know, plants are also good at purifying air. 10 square meters of woods or 25 square meters of grassland can absorb all the carbon dioxide that a person breathes and supply the oxygen needed. In the 1-11 month of this year, 370 thousand kinds of seedlings (including ground cover) were planted in the mountain park project in our city. These plants absorb a huge amount of carbon dioxide.
