| 摘要: |
| 农业生产受环境因素影响大，进入农耕文明以来，农业对气候的高度依赖局面没有得到根本性的改变，频繁的自然灾害给我国的农村经济发展造成了极大的困难。遥感技术是运用各类非接触的主被动的探测设备，对地面目标物的电磁波辐射与反射特性进行探测，通过其特性分析，探明其物体性质、特征及状态的综合性探测技术。它具有覆盖面积广、空间分辨率高、获取信息大、重访周期短等优点，适用于农业资源调查与自然灾害监测等农业相关领域的研究，对农业生产的指导与相关部门的决策管理意义重大。文章主要针对国内遥感技术在农业水循环与水环境的发展、应用现状进行综述与分析，并对遥感技术在农业水资源领域的发展趋势进行展望。 |

| Abstract: |
| The agricultural production is influenced by environmental factors.Since the beginning of the farming civilization, the situation that agriculture highly depends on the climate has not yet been changed fundamentally. Frequent natural disasters have caused great difficulties to the development of rural economy in China. Remote sensing technology is a comprehensive detection technology which can apply all kinds of non-contact active and passive detection equipment to detect the ground target by electromagnetic radiation and reflection characteristic,and study the properties, characteristics and state of objects through the characteristic analysis. It has the advantages of covering wide area, high spatial resolution, accessing to big information, short revisit period, and so on, and can be applied for agricultural resources investigation and natural disaster monitoring. It is of great significance to the guidance of agricultural production and the decision-making management of relevant departments. This paper mainly summarized and analyzed the development and application status of remote sensing technology in agricultural water circle and water environment, discussed the development trend of remote sensing technology in the field of agricultural water resources. |
