水危机

• In recent years , because of the low efficiency of natural resources and social resource in agriculture , the main agriculture resources are becoming shortage . reduced farmland area , crisis of water , the agriculture resources pollution
  摘要近年来，由于对农业自然资源与农业社会资源的低效率配置和掠夺式开发利用使得农业生产所需的主要农业资源面临短缺危机，耕地面积急剧减少、农业用水危机、农业资源污染严重、生态环境恶化等问题日趋严峻。
• The water culture , consisting of the ideas of water , the custom , institution , norm , religious element and so on , is the important foundation for the contemporaries to solve water crisis , to build a nicer water environment and to realize the sustainable development , and is the effective method of settling the problem of water environment from the source
  由水的观念、使用与保护水的习俗、制度、规范、宗教等构成的水文化，是当代解决水危机、营造良好的水环境、实现可持续发展的重要基础，是从源头解决水环境问题的有效手段。
• The dysfunction of market and government , the ambiguous property right and the definition of property of public goods , all these result in the extremely low water price , waste of water resource and severe water pollution . thus , the " water crisis " is triggered and becomes the bottleneck to economic development
  市场失灵和政府失灵，产权不清、公共物品属性等因素，导致目前国内水价过低、水资源浪费、水污染严重等问题，引发“水危机” ，使水资源成为经济发展的瓶颈。
• Abstract : in this paper , the major problems in water resources , flood and drought , and water environment in china are analysed , and new subjects of study on hydrology are pointed out , including the uncertainty of hydrological phenomena , the effect of human activities on hydrology , the calculation of water level frequency , the optimum effcet of water resource development and utilization , the analysis of water supply and demand , the mechanism of water - saving agricultural irrigation , flood and drought prevention , etc
  文摘:从水资源开发利用与保护、水旱灾害防治等方面论述中国当前存在的主要水问题：水危机和水浪费同时存在、水污染日趋严重、防洪减灾任重道远、生态环境破坏严重、全球气候变暖产生不利影响；进而论述水文学研究面临的新课题：水文现象的不确定性、人类活动对水文的影响、水位频率计算、水资源开发利用的最佳效应、水资源供需分析、农业节水灌溉机理及水旱灾害的防治，并指出必须加强对这些新课题的研究
