Time to open the park to visit the first "mosquito -free park" O -type blood on the spot. These three "treasures" are really hidden behind them.

Cover news reporter Yu Ting

In the hot summer, if you can have a good place to walk and play with water at your doorstep, it is better. On the side of the Jinjiang River, Mengmei Chasing the Bay, Red Star Bridge Head, a living water park with a tail -shaped fish is a "treasure" park in the hearts of many Chengdu people. At the same time as the purification function is also available, it is also "Chengdu Emei Mountain" and "Natural Air Conditioning House". It has more than 400 species of plants, which is about 3 ° C than the average daily temperature outside the garden.

In the 1990s, as a pearl in the comprehensive rectification project of the Fu Nanhe, Living Water Park created the first park in the world to complete water purification in natural ecology. Today, Living Water Park is the latest planning of Jinjiang Park. First, after this round of renovation, it became the first "mosquito -free park" by the Jinjiang River. How does this do? On the eve of the official opening of the park, the reporter of the cover news went to find out.

Playing a circle of type O blood is not bitten by mosquito

At 10 am, along the Jinjiang River, walking into the live water park that is about to be open, a refreshing coolness hit the heart, and the rich vegetation and the sound of the water picked away the hot summer heat.

According to the environmental monitoring stations in the park, the temperature in the park is about 3 ° C in average than the average daily temperature outside the park, and PM2.5 and PM10 are kept in single digits all year round. The entire park is built according to the water. Emei peach coral, Guanyin lotus fern, yew, and tongtong's eyes are full of green eyes, which makes people look like a dense forest in the mountains of Emei.

As a type O blood, even if it is half an hour in the upper half of the community yard in a better green area, the "recruiting mosquito" reporters who can "harvest" 5 or 6 mosquito bags can be stabilized. Beautiful scenery, always staring at his arm and calf, "mosquito monitoring radar" runs at a high speed, ready to capture the target at all times.

However, in the lap of the park, for more than an hour, without using any mosquito repellent potion and mosquito repellent stickers, there was really no bite by a mosquito in the whole body. Isn't such an environment the favorite of mosquitoes? How does the upgraded live water park balance the relationship between natural ecology and mosquitoes? Zhu Juntang, the director of the three directors of the Landscape Center of Chengdu Park City Construction and Development Research Institute, explained the mystery to us.

"The" Mosquito -free Park "we said is not really without mosquitoes. This is not in line with the rules of ecology. It is just through a series of measures to achieve the effect of" body sensation without mosquito "." Zhu Juntang first clarified the "mosquito -free park" The concept, he introduced that this is a new attempt for live water parks. In the future, the "Mosquito Holding Guide" will be launched simultaneously in Jinjiang Park, which will divide the density of mosquitoes in the park into different levels, and divide the corresponding prevention level according to the tourists.

Water purification water and 50 "hunters" common effects

As a 25 -year -old park, at the beginning of the design and construction of Living Water Park, it adheres to the green concept of water ecological governance with a natural ecology method. To achieve the effect of "somatosensory mosquito -free", in fact, during this repair and rectification process, green low -carbon and ecological upgrades are inseparable.

The most important point is that the "live water" and "water purification" in the live water park are relatively difficult to breed mosquitoes. The repair and rectification of the live water park further strengthened the multiple filtration and water ecological purification systems that have been in the live water park for many years, so that the water can flow naturally, purify naturally, reduce static water surface, and allow mosquito to have no reproductive conditions.

Secondly, adjust the plant varieties, and under the premise of ensuring the original vegetation ecosystem of the live water park, the number of original big Joe and vegetation coverage will not be changed. It is also effectively reduced the space for mosquito reproduction.

In addition, a major highlight in the renovation and rectification project of this live water park is to introduce more than 50 mosquito "hunters". These green boxes in the grass are "sitting" in the grass, and environmental physical bionic technology seduce blood -sucking mother mosquitoes.The principle of simulated human body breathing, by collecting carbon dioxide in the air, enables its own carbon dioxide concentration to the human level, so that mosquitoes mistakenly think that the human body is breathing to achieve the effect of capturing mosquitoes.After the mosquito catcher was enabled, it was found that the mosquito density of the park dropped from the initial 3.46/[Taiwan · hour] to 0.18/[Taiwan · hour].Therefore, the living water park after opening the park again will jointly realize the basic mosquito environment without mosquito no mosquito environment through various ways to adjust the plant species, the plant variety, and the mosquito "hunter", and create a more comfortable garden feel for citizens.
