This paper thoroughly demonstrates the water price of South-to-North Water Transfer Project from the viewpoint of economic policies. It is considered that if the project is assigned as a profitable one and built depending on commercial loan from bank completely or mostly, the water price will be too high to be undertaken by users,and if the project places the public good at first while considering the economic benefit, its investment mainly relies on the state (national or local governments) appropriation and self-raised funds and a little from the bank loan on favorable terms, the price determined according to the principle of satisfying the cost and reasonable profit will be relatively lower and can be undertaken by the users in the North China where water shortage is serious. The problem of higher water price of agricultural irrigation to the north of the Yellow River can be tackled by taking measures such as "compensating agriculture by industry" according to foreign practical experiences and relevant suggestions.展开更多

Some consumers are linking it to the latest reform in China＇s drug regulation history. In May, the National Development and Reform Commission （NDRC）, China＇s top economic regulator, announced the price ceiling imposed by the government on over 2,700 pharmaceutical drugs would be removed from June 1 onward.展开更多
为了探索由咸水灌溉引发的次生盐渍化棉田适宜的土壤盐度控制指标,试验于2012年在5个不同次生盐渍化水平的小区开展,0-60 cm深土层的初始土壤电导率（土水质量比为1∶5）分别为0.29、0.32、0.55、0.79、0.99 d S/m,分别以处理1-5表示。...为了探索由咸水灌溉引发的次生盐渍化棉田适宜的土壤盐度控制指标,试验于2012年在5个不同次生盐渍化水平的小区开展,0-60 cm深土层的初始土壤电导率（土水质量比为1∶5）分别为0.29、0.32、0.55、0.79、0.99 d S/m,分别以处理1-5表示。研究分析了盐分对棉花＂三桃＂比例、产量和纤维品质的影响,并建立了棉花价格模型,最后通过拟合分段式作物耐盐函数得出土壤盐度控制指标。结果显示,在平水年时降雨基本满足棉花需水要求,而且土壤中很大一部分盐分被降雨淋洗出0-60 cm深土层,并被控制在100 cm以下的土层中,与试验初始相比,处理1-5的最大脱盐率分别为9.6%、19.8%、36.4%、42.4%和45.7%,最终脱盐率分别为9.4%、1.8%、21.0%、24.5%和31.7%。当0-60 cm深土层初始土壤电导率低于0.79 d S/m时,没有显著降低成铃数和籽棉产量,仅会改变＂三桃＂比例,随土壤盐度进一步增高,成铃数和籽棉产量显著降低。棉花衣分率和纤维品质指标受到采摘时间和土壤盐度的共同影响,仅马克隆值在3次调查中都随着土壤盐度增加呈增大的趋势。由棉花净收益决定的土壤盐度指标低于由籽棉产量决定的土壤盐度指标,证明考虑纤维品质指标的必要性。在与处理1的净收益相比不降低的情况下,棉花播种初始和生育期平均土壤电导率应该分别控制在0.71和0.67 d S/m以下。该研究为改善次生盐渍化棉田土壤盐度控制指标的确定方法提供了理论参考。展开更多
