At last , the scouring and sedimentation process of qtx reservoir at different operation way are calculated and forecasted by using of this model , the problems existing on operation way are pointed out , and the optimum adjusting water and sediment operation way in the future are put forward 最后利用该模型对青铜峡水库不同运用方式的水库泥沙冲淤过程进行预测计算，指出了青铜峡水库以往运行方式上存在的问题，提出了今后水库最佳调水调沙运用方式。
The outcomes show that not only the channel near the outlet has been extended , but also the created land area increased to varying degrees during the tests of a regulated discharge regime of the river and ; a regulated discharge regime has significant roles on keeping the balance of erosion and deposition of the estuary 结果表明：调水调沙期间，河口口门附近不管是河道延伸，还是造陆面积都有不同程度的增加；调水调沙对河口的冲淤平衡有重大的作用。
Modeled around the assumption that water usage rights constitute the foremost of the transactions in licensing or trading of the trans - regional water drainage rights , this paper thoroughly analyzes the domestic practices of water rights licensing as well as those of the abroad to support the main argument 通过分析我国跨流域调水产生和发展的时代背景，国内实践经验及国外跨流域调水水权交易的具体做法，阐明了在我国进行跨流域调水水权交易的必要性和可行性。
The results of experiments and investigations in many years showed that in the semi - damp soil , the output had been increased by 69 . 2 % when the former is used to guide the optimum sowing time for the plastic - film corn , and in the semi - arid area and the yield of corn increased by 60 . 0 % when the latter was used , for , when used , the output will increase only by 15 . 7 % and dropped by 14 . 4 % less than the latter 经多年的试验和调查表明，在半湿润生态类型区，应用“增温说”指导地膜玉米最佳播期增产69 . 2 % ；在半乾旱地区，应用“调水说”指导地膜玉米最佳播期增产60 . 0 % ，而应用“增温说”播期只增产15 . 7 % ，比“调水说”播期减产14 . 4 % 。
