[Abstract]:The hydrological climate leads to the imbalance between precipitation and evaporation in inland arid region respectively. Xinjiang has entered the bottleneck period of serious shortage of water resources. Water resources have become the leading factor restricting the sustainable development of society economy and environment in Xinjiang. Based on the serious shortage of the total water resources in Xinjiang, this paper explores how to effectively reduce the evaporation of the water surface of the reservoir and improve the effective supply of water resources by reducing the consumption of a large amount of water resources due to the evaporation of the water surface of the reservoir. Taking a reservoir in Changjizhou, Xinjiang as the research object, this paper intends to use the plastic hollow board as the experimental material to carry out the experimental study on the evaporation prevention and water saving of the plain reservoir, so as to achieve the purpose of preventing evaporation and saving water in the plain reservoir. In this paper, a new type of evaporation-proof material, plastic hollow board, is selected by mechanical calculation and material performance test, and a certain number of plastic hollow panels with a veneer area of 1.5m2 and thickness of 15cm are selected. A one-year field test of partially covering the reservoir surface in plain area was carried out. By means of contrast and cross test, the data of anti-evaporation effect were recorded in different arrangement ways and different size of area. The results showed that the thickness of plastic hollow plate was 15 cm, and the best anti-evaporation effect was the type of interconnecting plate. In addition, long-term anti-evaporation materials can be re-examined the material's folding, frost resistance and other properties. By summarizing the experimental data and according to the relationship between the influence factors of water surface evaporation and the water surface evaporation capacity, a multi-factor water surface evaporation model was preliminarily established. Based on the data processing of the relationship between the influence factors of water surface evaporation and surface evaporation, the model parameters are determined by correlation analysis, and then a water surface evaporation model suitable for local use is obtained. According to the data of many years, the error analysis of the calculation results of evaporation by the new model is carried out. Finally, on the basis of the evaporation quantity calculated by the new model, the effective evaporation control capacity of the evaporative material under the action of a meteorological factor is calculated under the condition of complete coverage of the new evaporative material and partial coverage of the reservoir surface. The results show that, The effect of preventing evaporation is good. The experimental observation and data statistics show that the anti-evaporation effect of the plastic hollow plate selected in this experiment is 85.7, which is effective for the effective utilization of the surface evaporation of the plain reservoir in the inland arid area, and the selection of the anti-evaporation material is reasonable.
