作为农业大国,农业一直是我国国民经济的重要组成部分。水资源对于农业的健康发展至关重要,但由于我国水资源总量少,分布不均匀,总体指标相对较差,加上我国经济发展非常迅速,工业用水不断增加,气候异常,干旱不时爆发,农业用水成了制约我国农业发展的主要因素之一。为了从根本上解决我国农业用水紧张的问题,就要全面认识和了解我国农业用水现状以及存在的问题,然后分析农业水循环结构以及农业水资源转化效率,利用农业水循环原理,剖析我国农业用水每个环节水资源的消耗效率,进而提出优化我国农业水循环,促进我国农业健康发展的调控对策。
As a big agricultural country, agriculture has always been an important part of our national economy. Water resources are crucial to the healthy development of agriculture. However, due to the small total amount of water resources in our country and uneven distribution, the overall indicators are relatively poor. In addition, with the rapid economic development in our country, the continuous increase of industrial water use, the abnormal climate and the outbreak of drought, Agricultural water has become one of the main factors restricting the development of agriculture in our country. In order to fundamentally solve the problem of agricultural water shortage in our country, it is necessary to fully understand and understand the status of agricultural water use in our country as well as existing problems. Then, the structure of agricultural water cycle and the conversion efficiency of agricultural water resources are analyzed. Using the principle of agricultural water cycle, Link the consumption efficiency of water resources, and then put forward the regulation and control measures to optimize the agricultural water cycle in our country and promote the healthy development of agriculture in China.
