Kunming City Constructed 65,000 Hydraulic Projects in 10 Years

Through the following figures, we can see that in the ten years, Kunming had a deeper understanding of the construction of water conservancy projects, awareness of water hazards, and concept of water law. The benefits of the project are significant. The production conditions and living standards of farmers have been increasing year by year, and urban water has been further improved. Safeguards have made outstanding contributions to the construction of water conservancy and hydropower projects in Kunming. In the past 10 years, Kunming City has built a total of 65,954 various types of water conservancy projects, including 52,865 years old repairs, new, continued, and expanded 13,089 middle- and small-scale water conservancy projects, accumulatively invested 6.2221 million man-days, and 38.79 labor-employed workers. Completed 510,303,300 cubic meters of earth and stone, completed 3,541 kilometers of anti-seepage treatment of various types of channels, completed 9 stations of small hydropower stations, installed 11,170 kilowatts of water, and 65,949 pieces of water conservancy projects invested 679,472,800 yuan in total. Water is the "blood" of urban development and an important basis for the economic prosperity and sustainable development of cities. The Songhuaba Reservoir, which is known to all people in Kunming, provides urban water, which accounts for 60% of Kunming City's water use. It is a model for water supply to provide sufficient "blood" for the city. Songhuaba Reservoir was built in 1958. From 1988 to 1995, it invested 130 million yuan to carry out reinforcement and expansion projects, which increased the design storage capacity from the past 70 million cubic meters to 219 million cubic meters. After the expansion of Songhuaba Reservoir, the water supply to the city was greatly increased, which basically met the needs of Kunming's urban development. At the same time, Kunming’s “2258” water diversion project for the Jigong project attracted 50 million cubic meters of high-quality water from the Baoxiang River in the east, the Shalang River in the west, and Chaihe and Dahegong in the southern line, solving and improving the eastern and western parts of Kunming. About 800,000 people live in the south. While increasing urban water infrastructure construction, Kunming has also increased protection of water source protection areas. In 1989, Kunming City promulgated the “Regulations on the Management of Songhuaba Water Source Protection Area in Kunming City.” In the area of ​​forest coverage in water conservation areas alone, the forest coverage of the Songhuaba Reservoir Conservation Area was restored and improved by 27% of the initial period of establishment. It is now 59%. Water is called "first production data" in rural areas. While constructing a batch of large, medium, and small-scale backbone water conservancy projects, Kunming City will focus on building high-yield production fields through water conservancy facilities, tapping potential renovations, and supporting systems for impervious canal systems. In mountainous areas and semi-mountainous areas, irrigated land and five small projects will be the main targets. . For poverty-stricken areas, the project arrangement and funding are tilted to make important contributions to the task of poverty alleviation in our city and promote social and economic development in various regions. During the Ninth and Tenth Five-Year Plan period, Kunming completed the construction of the Shihashitan Reservoir Barrage Dam as a concrete facing rockfill dam with a maximum dam height of 101.8 meters, a total storage capacity of 437 million cubic meters, a normal storage capacity of 340 million cubic meters, and a water storage capacity of 2.55 Billions of cubic meters, irrigating 191,600 acres of farmland; after the completion of the reinforcement project, the upstream reservoir of the Mingming County can irrigate 46,000 acres of farmland. Shiying County, Weihe Reservoir has serious leakage due to the dam foundation and the slopes and spillways of the two banks. With only 600,000 to 800,000 cubic meters of inventory, it can only irrigate 10,000 mu of farmland, and the benefits of facilities will not be realized for a long time. In order to solve the problem of reservoir leakage, the city will reinforce the reservoir and the project will be implemented in three phases. On the basis of the greater success of the first phase of the project, the leakage treatment of the second-stage spillway has started. The project has invested more than 3.76 million yuan. After the completion of the project, with the completion of the construction of the irrigation area, the reservoir can irrigate more than 70,000 mu of farmland. According to statistics, in the 10 years, Kunming City added 1.291 million mu of irrigated land, improved 4,048,800 mu of irrigated area, 680,300 mu of water-saving irrigation area, restored 61,000 mu of irrigated area, treated 1733.95 km2 of soil erosion, and built high-yield production fields. 110.12 million mu, with a high stable production area of ​​1,078,700 mu, solved and improved 972,900 people, and 471,600 head of livestock had difficulty in drinking water. The problem of urban water supply is an important basic condition for the construction of modern Kunming. Water supply in the outer basin is a powerful measure to solve the contradiction between supply and demand for water resources in modern Kunming. It is understood that in the future, Kunming City will strive to complete the "Qingshuihai Water Diversion Project" and "Baoxianghe Reservoir Flood Control Project" two major projects. At present, the “Baoxianghe Reservoir Flood Control Improvement Project” has started construction. The project implements the flood control and rectification of the Baoxiang River system, and the river flood protection guarantee rate can be increased from one time in five years to one in 50 years. The sustainable economic and social development in the area is of great significance, with significant social and environmental benefits. The project was rectified from the Yangshuo Gate to the mouth of the Baoxiang River, and the length of the river course was 8.9 kilometers. According to the analysis of the supply and demand of water resources for each planning level in the two water receiving areas of the Aviation City and the Dongcheng, the “Qingshuihai Water Diversion Project” will be constructed in one phase and two phases. The first-phase project can achieve an annual water supply of 107.9 million cubic meters. The construction projects include expansion of the Qingshui Sea, construction of the Banqiao River, Shiqiao River, Jinzhongshan Reservoir, reconstruction of the new Tianhe Reservoir and nose-collapsed Longtan, and construction of a water transfer from the Qingshui Sea to the Jinzhongshan Reservoir. Tunnels, and water lines from Shiqiao River to Qingshuihai. In addition, Kunming will complete a number of project construction projects including "Renovation of rivers and floods," "Kunming city flood control," and "Middle and small-sized reservoir reinforcement projects."
