During the 13th Five-Year Plan period, China’s total water resource demand will continue to rise. The course group for the “Teams and Strategic Choices of my country’s Near and Medium-term Economic and Social Development” in the middle of the Development Research Institute of the National Academy of Economics and Social Development” was conducted on a specialized discussion and forecast based on the economic development stage and the history of water use changes in the development country:
By 2020, industrial water use will be relatively stable after reaching its peak, and Sugar baby will be between 165 billion and 170 billion cubic meters; the total agricultural water consumption will slowly fall with the increase of water use, and will be wandering at 380 billion cubic meters; the total life water consumption will rise stably, rising to 95 billion cubic meters, becoming the main force to promote the increase in future water consumption; the total ecological water consumption will slowly rise with the strengthening of ecological construction, which should be between 20 billion and 25 billion cubic meters.
The total amount of water in Class IV is added to the sum of Sugar daddy, which is approaching the lower limit of China’s total water resources at the end of the 13th Five-Year Plan. Therefore, there is a need to explore a grand space for water resource development through relevant technical innovation.
Wedding Photography Base beside the sewage treatment pond
A village called Sheshan Village on the bank of Poyang Lake, a pair of rural newlyweds are taking wedding photos, and the pool lotus and green trees are hidden in the scenery.
This is not a natural mountain scenery, but a sewage treatment pool in this small village. A ladder-level artificial wetland sewage treatment system composed of oxygen ponds, ecological ponds and purified ponds. What will the life of the entire village be prosperous? Didn’t he be cut the same way. The sewage flow thus becomes Sugar daddy purified water that can be used for greening irrigation.
In Poyang County, ecological villages like Schshan Village are becoming the sample of ecological management in Hubin Township. Poyang County, located on the east bank of Poyang Lake, is a representative of the county city and a vicissitudes of life. It has 1.5 million Jiangxi’s first-born county, and is also a financial county. The annual expenditure of financial year has just exceeded 1 billion yuan. At the same time, this area is Manila The ancient county city with an area of more than 4,000 square kilometers has a large amount of 4,000 square kilometers.gar.net/”>Sugar daddy is more than 200 lakes, and the smoke waves are very small, and it looks invisible.
The biggest threat to the ecological protection faces comes from the clean-up of agricultural and agricultural industries. The management difficulties are that, on the one hand, the rural areas are large, with evacuated bodies, and the basic environmental protection facilities are poor; on the other hand, Sugar baby, the current situation of eating and financial affairs is difficult to gather sufficient funds to invest in the rural areas.
The practice in Poyang County is to change at random, apply the terrain characteristics of local terraces, and use the method of biological pollution control, and apply the ladder-level people. daddyThe wetland sewage treatment system passes the rural sewage through this system, one layer of filtering, and transforms the entire village sewage into a clean water that can be used for greening irrigation.
As a financial county, the funds are of course unlimited, so the local area will build new rural areas and maintain environmental protection. escortThe tasks combined to concentrate all kinds of evacuation funds.
Today, Poyang County has promoted the construction of ecological villages for 300 natural villages within 2 kilometers of Poyang Lake, focusing on the greening of the family garden, concentrated collection of waste residues, building marsh gas ponds and sewage treatment. In order to ensure that the silt and sand do not flow to Poyang Lake, the waste does not wander to Poyang Lake, and the sewage does not flow to Poyang Lake, and the sewage does not flow to Poyang Lake, and the sewage does not flow to Poyang Lake. BabyYanghu’s “three goals”.
The “Sea King” on the old road of Yangguan
The town of Yangguan, located under the ancient yang, is the ecological feather of Dunhuang.
This 32-square-kilometer green is located 60 kilometers northeast of Dunhuang. Further west are the Kumtag Gobi and Rop Nur. It is different from the Poyang Lake in Fengshui, and is far away from the Dunhuang Town in the southeast.The Sun created a different kind of water control miracle.
Since ancient times, Yangguan has been the first line of defense to fight against wind and sand. It was extremely dry here, with evaporation reaching 80 to 100 times that of precipitation, and the Gobi Desert is severe, and the sand storm is rampant. The trees planted withered withered trees, and planted again after they were erected. The wind-proof forest of more than 2,000 meters was buried in sand dunes, and the remaining 200 meters were left with only the trees.
Disaster is more difficult than this. The sanitary, known as “drought and escort”, is often suffering from water disasters. Due to the low terrain, every flood season, all the rainwater from Dunhuang, Beibei and Aksai gathers here, and the flood will rush down with a large amount of mud and sand, gently purifying the water source, and seriously destroying the road, farmland and villages. The flood became a dream that people here could never cancel.
In 2001, an entrepreneur named He Yanzhong came here and used the cold water resources of Qilian Snow Mountain to develop cold water breeding rainbow fish industry on the Huangtu Plateau, filling in the vacancies of rainbow fish breeding in the high-cool and arid areas of the western region. In Gansu, He Yanzhong is called the “King of Raised Fish”.
This entrepreneur finally fell into Longle Village, Guanzhen, Yang, and tightened the Kumtag Gobi. At first, he took a fancy to this because there was a source of water – the Western Tujing. From June to August every year, the snow-capped water of Qiwan Mountain and Alkin Mountain flows down, making it a great place to breed rainbow fish.
After the scene was first established, the floods and cements flows that followed in 2006 destroyed the fish pond and silted, and a billion yuan investment was invested.The water was drifted. He Yanzhong did not give up and invited a group of experts from home and abroad to manage sand and water to start a trial of water control. He first followed the mountain pass. baby Build flood diversion rivers in the Gobi, dividing the floods that have fallen into zero in the Kumtag Gobi, so that the greens can be protected from the frequent disasters. The sand barrier known as the “Gobi Long City”, not only prevents the sand dunes from moving forward, but also stores the diverted flood water. In this way, the accumulated flood water cultivates the water source to form a “groundwater tank”.
In the end, the side sections of the “groundwater tank” were dug open around the “groundwater tank”, so that the clearer floods flow out and become new waterSugar baby source, and then plant green trees to restore ecology. The gurgling clear streams saved the fish farm and also allowed the dead protective forest to return to green. As a result, this project is also called the “Gobi Dujiangyan”.
