global gold sound | why can beijing groundwater level "grow taller" for 9 consecutive years?
—— from the ten new data, look at the high -quality development base of china's economy ③
a drop of spring water flows out of beijing's new changes.
under miaofeng mountain, the spring eyes of chenjiazhuang village, mentougou district, beijing once again surged in water. in recent years, there have been 81 kongquan eyes in beijing.
spring is a barometer of groundwater. gurgling clear water flows out of the ground, becoming an intuitive reflection of the rise in groundwater levels. a set of data is surprising: from june 1 to september 15 this year, rainfall in beijing formed 2.683 billion cubic meters of water resources, and groundwater levels have risen for the ninth consecutive year. from 2015 to the present, the groundwater level in the beijing plain area has risen by 13.14 meters, increasing reserves by 6.7 billion cubic meters.
groundwater is an invisible and precious resource that has both resource and ecological attributes. it is indispensable for production and living water. smooth rivers and lakes, and lush vegetation also require groundwater conservation.
beijing's water resource endowment is "congenitally insufficient" and "acquired overload". the per capita water resource is far below the internationally recognized extreme water shortage standard of 500 cubic meters per capita per year. groundwater once became the main water source, responsible for the daily operation of this megacity. from over-exploitation and water level decline, to rebounding, and now continuing to rise, why can beijing's groundwater levels continue to "grow higher"?
first, this is the common result of "heaven help" and "people work hard".
raining is mostly the reason for objective reasons, so that rainwater can be kept, relying on "people's efforts". in the 2024 flood season, beijing's rainfall is more than 60% higher than normal. reservoirs such as miyun reservoir and huairou reservoir have a flood blocking rate of 100%. the urban factories, networks and rivers are dispatched in an integrated way, with "west storage, east discharge, and north-south flood diversion" to allow the flow of water to flow. what needs to flow away, what needs to stay remains, and what needs to permeate permeates. from june 1 to september 15 this year, beijing’s groundwater reserves increased by 1.42 billion cubic meters compared with before the flood.
groundwater levels continue to "grow higher", which is inseparable from the modernization of water conservancy infrastructure. the engineering systems such as reservoirs, embankments, and flood storage and detention areas are more complete, storage and drainage are coordinated and coordinated, the urban pipe network is continuously upgraded, and the construction of sponge cities is advanced in an orderly manner. on the basis of ensuring flood control safety, rainwater resources are collected, intercepted and infiltrated to effectively replenish groundwater and improve urban water ecology.
second, this is the scientific scheduling of external water -adjusting and local water.
what to do if there is a shortage of water? "external water transfer" helps. seventy percent of the "south water" flowing into beijing is used for domestic water use by urban residents. in the past ten years since the central route of the south-to-north water diversion project was opened, more than 10 billion cubic meters of water have been transferred to beijing, and more and more "south water" has replaced groundwater. the five-water joint regulation of surface water, groundwater, reclaimed water, rainwater and floodwater, these local waters and "external water transfer", the multi-source water resources guarantee system has consolidated the security of water supply and allowed the once overused groundwater to "take a breath".
behind the multi -water source adjustment is the continuous improvement of water resources configuration. major cross-basin and cross-regional water diversion projects such as the south-to-north water diversion project have brought benefits. "capillaries" such as ditches, ponds and dams have continued to extend, and the national water network has smooth circulation. north-south allocations, east-west mutual aid, peak reduction and dry supply have been achieved, and optimal allocation of water resources has been achieved.
third, this is a two-pronged approach of increasing revenue and reducing expenditure.
to solve the water shortage, water conservation is the fundamental solution.北京加强地下水禁采区、限采区管理，摸清机井家底，织密保护网。颁布实施《北京市节水条例》，推进生活、农业、工业、园林绿化、公共服务等领域节水。 high -precision industries such as the digital economy, information technology and service industries have flourished, and the amount of product water consumption in 10,000 yuan in 10,000 yuan in beijing maintains a leading level in the country.
the fundamental key is to make good use of the "gate" of the new development concept, which is the green development concept deeply rooted in the hearts of the people. the beijing -tianjin -hebei region is one of the widest, largest, and most intense areas in the world. the fundamental method is to promote the superpower governance of groundwater in north china is to change the method of water consumption, improve the efficiency of water use, and save intensive use of water resources. treat water resources as a "hard lever" and continue to promote agricultural water conservation and efficiency improvement, industrial water conservation and emission reduction, urban water conservation and loss reduction, and groundwater utilization from disorderly exploitation to scientific management.
视线拉长，从一地观一域。 changes in groundwater levels reflect the transformation of my country's water resource utilization from extensive and inefficient to intensive and efficient. efficient water use, scientific water diversion, and precise water supply. in the past 10 years, with the gdp nearly doubling, my country's total water consumption has achieved zero growth.
water use methods are connected with development methods, and there is a long way to go to save and intensively utilize water resources. we must insist on giving priority to water conservation, and use water to determine cities, water, land, people, and production. all localities should adjust agricultural planting structures, optimize industrial layout, and encourage the development of innovative and high-tech industries according to local conditions. "there are as many soups as there are steamed buns for making". make careful use of groundwater to save water and expand development space.
it is necessary to maintain spatial balance and coordinate "one game of chess". based on my country's basic water conditions of summer floods and dry winters, and lack of abundant water in the north and south, the upstream and downstream, left and right banks, and main and tributary regions cooperate with each other to pool their strength to further optimize the national water network, fully tap the potential of the built storage diversion and diversion projects, and continuously enhance water supply. the adaptability of resource elements and economic and social development.
it is necessary to adhere to systematic governance and improve the integrated protection and system governance mechanism of landscapes, forests, lakes and sand. from the water to the shore, we protect rivers, regulate shorelines, plant forests and grasses, and prevent wind and sand. we provide overall protection, systematic restoration, and comprehensive management to make water circulation smoother and rivers and lakes healthier.
we must adhere to both hands, further strengthen groundwater supervision, strengthen restrictions on mining, and delineate red lines. at the same time, we will deepen the reform of water rights, water prices, and water resources taxes and fees, and make good use of green financial tools such as "water-saving loans" to support the development of the water-saving industry and stimulate the enthusiasm of business entities to participate in water-saving work.
for a long time, we can do it, and strictly from the fine -tube groundwater, so that we can leave more precious groundwater resources for future generations.
