Water body transparency exceeds 1.2 meters!Create a "underwater garden", Suzhou's cheats are ...

"Garden water body transparency exceeds 1.2 meters! It meets the standard of water quality standards for landscape entertainment, and even some garden water quality has reached Class III and III water standards."

Today (July 21), the exchanges of water governance experience in garden system in 2022 were carried out in Suzhou. Experts and scholars gathered in the Humble Administrative Garden and shared around the garden water body management protection technology and experience.

Ecological regulation, dynamic monitoring, and multiple purification methods are used together to apply the right medicine. The water of Suzhou Gardens is "not turbid and anti -clearing." Behind the clear bottom, how to get out of the characteristics of Suzhou? In the next step, how can Suzhou polish the business cards of Jiangnan Water Village and draw a step -by -step water painting Jiangnan?

As the saying goes, the most beautiful place in Suzhou gardens is water, water without water, and no water without water, so there is "waterless garden, the garden is alive because of water".

In the 1980s, due to the acceleration of the urbanization process, garden water began to appear to varying degrees of negative nutritionalization. How to make garden blood live an important issue facing gardeners.

In order to restore the beautiful and beautiful garden water bodies, in recent years, Suzhou gardens have embroidered with water quality management, using a variety of technical means to carry out garden pond water management work, obtain staged breakthroughs, and the level of governance is at the forefront of the country.

At present, the water body transparency of Suzhou Garden Scenic Area has basically reached more than 1.2 meters. Behind the 1.2 meters of clear and bottom, what is the maintenance secret of Suzhou gardens?

As the "model student" of Suzhou Garden Lishui, the underwater world of the Humble Administrator's Garden, the aquatic grass swaying, and the fish swimming, like an underwater garden.

In the garden, Ms. Zhu from Nantong is taking her daughter to visit. Out of the sensitivity to professionalism, she has studied environmental protection at Suzhou University of Science and Technology and noticed the significant changes in the water quality of the Humble Administrator's Garden.

"As soon as I entered the garden today, I felt that the water color was not as turbid as before, and it was very clear." She also mentioned that the water quality is good, and the ripples on the water surface can observe one or two. "Today, the water quality of the Humble Administrator's Garden is better, and the ripples of the water surface are even more rippling. As a tourist, you can see it more comfortably."

It is understood that the layout of the Humble Administrator's Garden is centered on water and has a typical "Pingyuan Landscape" style. The total area of ​​the overall waters is about 9190 square meters, and the total water volume is about 6150 cubic meters. At present, the transparency of the water body can basically reach 1.5-1.6 meters.

Cheng Hongfu, deputy director of the Suzhou Humble Administrative Park Management Office, and reporters revealed that the improvement of water quality in Human Government Park relies on a "natural water purifier" that runs day and night.

"The Humble Administrative Garden uses ecological regulation technology, that is, rely on the water ecosystem to control the number of algae and plankton, thereby achieving the effect of self -purification of water bodies. At present, the Humble Administrator's Garden has formed a grassy, ​​bitter grass, water shield grass, and water. Black algae, goldfish algae, etc., mainly sinking water plant groups, protect the underwater ecology throughout the quarter. "

Different from the Great River Lake, the water area of ​​the Suzhou garden is relatively small. The water can not be "fierce medicine".

The ecological regulation is like prescriptions, the type of plant, the proportion of planting, and the growth rate of the plant.

Underwater in the Humble Administrator's Garden, the reporter saw a lot of aquatic plants similar to leek, and the scientific name was bitter grass. "Originally our pond water body lacks the sinking water plant that can overwinter, which has led to obvious defects in the seasons of the sinking water plant season in winter and spring. After increasing the bitter grass with appropriate proportion You can improve significantly. "

The clear surface is as clear as a group of unknown Qing Daofu. In the garden, the reporter saw many staff members under the scorching sun and was carrying out the cleaning and salvage work.

Chen Yan, director of the Garden and Park Management Division of the Municipal Garden and Greening Administration, told reporters that in addition to manual cleaning, the Suzhou Garden Bureau Heritage Protection Supervision Center has entrusted the Suzhou University Institute of Health and Environmental Technology since 2013 to conduct nine world cultural heritage gardens The water bodies of Hehuqiu Scenic Area carry out 1 monthly monitoring, which mainly detects and analyzes the water quality conditions and the transparency of water bodies.

"In addition, considering the degree of pollution of various garden water body pollution and different sources of pollution, we also adopted a variety of purification methods to achieve an effect of comprehensive governance." Chen Yan said.

Participated in the investigation and research of gardening water for many years, in Cheng Hongfu's view, water scenery is the soul of Chinese classical gardens. "If the pond water is turbid and the aquatic plant configuration is not in place, it will affect the presentation of the building on the waterfall. It will affect the expression and presentation of classical garden landscape aesthetics. "

Therefore, gardening water not only stays at the level of water environmental protection, but also the cultivation of waterweeds is more particular about the landscape of Oriental aesthetics. It is necessary to consider the buildings and waters of the water and waters of the garden water, to reach each other and the world.

In today's Humble Administrator's garden, the steps are different, attracting many tourists to stop taking pictures. It can be seen that in order to do a good job of "water control" and polish the business cards of Jiangnan Water Village, in recent years, the garden has made a set of "combination boxing" with Suzhou characteristics in terms of water quality protection.

It is reported that in the next step, the municipal garden authority will fully grasp the latest situation of garden water quality through dynamic monitoring, provide timely, accurate and reliable data information for water body governance, and provide a scientific basis for summing up the experience of water body governance; The special governance project of Huqiu Huanshan River has completely improved the water quality of the mountains and rivers by planting sinking water plants, adding micro -nanometer aeration compounder, and equipped with water pump room purification control systems, and realizes the intelligent control of landscape water.
