我国是人多地少的国家,同时土地生产能力受到水资源等自然条件的严重制约,长期以来旱涝盐碱自然灾害连续不断,阻碍农业生产的发展。水利建设成为提高土地承载能力的主导因素。合理开发利用水资源,在农业生产发展中占有极其重要地位和作用。因此,强化水资源管理,大规模开展以水利建设为中心的农田基本建设,使我国土地生产能力在原有基础上走上新台阶,是确保我国人口不断增长和国民经济发展对食物需求的根本性措施。

China is a country with insufficient land and a large population. Meanwhile its land productivity is seriously restricted by water resource and other natural conditions. Since ancient time, natural disasters such as drought, flood, salinization and alkalization occur contin-ualy, which hinders the agricultural development. Water conservancy has become a leading: factor in increasing the carrying capacity of the land, so that the rational developmend of water resource plays a more and more important role. Therefore, strenthening the management of water resource and developing a large scale fundamental farmland construction which focuses on the water conservancy are the significant methods to raise the land productivity from current situation to a new level. In doing so the demand for food by the increasing population and natural economy can be ensured.
