Small-scale farmland water conservancy projects are crucial infrastructure for ensuring agricultural production and enhancing water resource utilization efficiency,with their water-saving benefits directly linked to national food security and sustainable agricultural development.This study focuses on small-scale farmland water conservancy projects in China,identifying issues such as aging facilities,outdated technology,and management deficiencies through field research and data analysis.Targeted pathways for enhancing water-saving efficiency are proposed from three dimensions:engineering technology optimization,management mechanism innovation,and policy support.Research indicates that by promoting efficient water-saving technologies,establishing a diversified management model,and improving policy incentive mechanisms,the irrigation water utilization coefficient of small-scale farmland water conservancy projects can be increased by 0.1-0.15,and water consumption per unit area of farmland can be reduced by 15-20%.The findings provide theoretical references and practical guidance for the quality improvement and water-saving enhancement of small-scale farmland water conservancy projects in China. 展开更多

Based on the theory of activity-based costing and the idea of value chain,activity optimization and cost control are carried out on the whole construction process of agricultural water conservancy projects. Through the use of literature review,case analysis and statistical analysis and other methods,with agricultural water conservancy projects as the research object,and comparing activity-based costing with the traditional model of cost accounting,the writer carries out the corresponding value chain analysis,and comes to the following conclusion: the statistical calculation and analysis of the entire construction process based on activity-based costing can accurately and effectively control the costs of water conservancy projects. Through the use of activity-based costing,the cost data of agricultural water conservancy projects is more detailed and accurate,and cost management personnel can also find non-value-added activities,optimize the enterprise's value chain and achieve cost control objectives through the analysis of the activity chain and value chain of agricultural water conservancy projects. 展开更多

With the development of society, the development of irrigation and water conservancy projects in China has also advanced by leaps and bounds. In small-scale farmland water conservancy projects, river regulation is an effective means to maintain the long-term use of water conservancy projects. The purpose of constructing small-scale irrigation and water conservancy projects is to promote good cultivation of farmland and realize the balanced utilization of water resources. With the construction of small-scale irrigation and water conservancy projects, the problems in river regulation are gradually emerging. Therefore, relevant personnel need to analyze and investigate the problems existing in the course of river regulation of small-scale irrigation and water conservancy projects and work out effective solutions. 展开更多

In this study, we simulated water flow in a water conservancy project consisting of various hydraulic structures, such as sluices, pumping stations, hydropower stations, ship locks, and culverts, and developed a multi-period and multi-variable joint optimization scheduling model for flood control, drainage, and irrigation. In this model, the number of sluice holes, pump units, and hydropower station units to be opened were used as decision variables, and different optimization objectives and constraints were considered. This model was solved with improved genetic algorithms and verified using the Huaian Water Conservancy Project as an example. The results show that the use of the joint optimization scheduling led to a 10% increase in the power generation capacity and a 15% reduction in the total energy consumption. The change in the water level was reduced by 0.25 m upstream of the Yundong Sluice, and by 50% downstream of pumping stations No. 1, No. 2, and No. 4. It is clear that the joint optimization scheduling proposed in this study can effectively improve power generation capacity of the project, minimize operating costs and energy consumption, and enable more stable operation of various hydraulic structures. The results may provide references for the management of water conservancy projects in complex river networks. 展开更多

Water regulation of the Xiaolangdi Reservoir of the Yellow River was chosen as a case to investigate variations in concentrations and bioavailability of heavy metals caused by water conservancy projects in rivers. Water and suspended sediment(SPS) samples were collected at downstream sampling sites along the river during this period. Concentrations and speciation of Zn, Cr, Cu, Ni, and Pb in water and SPS samples were analyzed, and their bioaccumulation was studied with Daphnia magna. This study indicated that the exchangeable and carbonatebound fractions of heavy metals in SPS decreased along the studied stretch, and the dissolved heavy metal concentrations increased along the river with 1.6–15 folds. This is because sediment resuspension increased along the river during water regulation, giving rise to the increase of heavy metal release from SPS. The dissolved Zn, Cu, Ni, and Pb concentrations were significantly positively correlated with SPS concentrations, and their increase along the river was greater than Cr. The body burdens of heavy metals in D. magna exposed into samples collected from the reservoir outlet were 1.3–3.0 times lower than those from downstream stations, suggesting that the heavy metal bioavailability increased during water regulation.This should be considered in the reservoir operation. 展开更多

The conditions for the positive operation of water conservancy projects are described in this paper. A scientific and effective evaluation index system was established based on frequency analysis, theoretical analysis, and expert consultation. This evaluation index system can be divided into six first-level indices: the degree to which facilities are intact and functionality standards are reached, the status of operation and management funds, the rationality and degree of advancement of the management team structure, the adaptability and rationality of the water conservancy project management system, the degree of automatization and informationization of the management techniques, and the conduciveness of the exterior environment. The weights for evaluation indices were obtained through the analytic hierarchy process method with consideration of the difference between public welfare and profit-oriented water conservancy projects. This study provides a scientific method for evaluating the positive operation of water conservancy projects. 展开更多

The quality of these projects is related to human life, health and safety. Therefore, the quality monitoring of water protection projects is very important. The development of water conservancy projects has promoted the development of China's economy, but at the same time, problems in the management of construction technology are gradually exposed. Whether these problems can be solved scientifically and reasonably will directly affect people's personal and property safety and the further development of society. Agricultural development largely depends on the quality of small-scale water protection projects. Quality monitoring and management need to be strengthened to improve the quality of water protection projects. This document analyses in depth the quality control issues of the projects at this stage, and puts forward effective countermeasures to improve the ability to resist agricultural disasters, improve agricultural production conditions and promote rural economic development. 展开更多
