Abstract:

Irrigation and water conservancy project is a necessary condition for agricultural production and development. But at present, there were some problems in farmland water conservancy construction in Karst mountainous areas. Therefore, it is of important and realistic significance to strengthen the studies on the construction of farmland water conservancy for developing farmland irrigation water conservancy, rational planning and layout, and increasing grain yield in Karst mountainous areas. Taking Guizhou Province as an example, this paper briefly expounded the construction and development of irrigation and water conservancy engineering during the recent years, including application of advanced technology and efficiency evaluation. Meanwhile, it also put forward problems existing in irrigation and water conservancy engineering in Karst mountainous areas, and relevant solving measures and suggestions. Before ending, the paper pointed out the development trend for farmland irrigation and water conservancy engineering is to apply new and high technology, to save water and farmland, to realize management modernization, to protect landscape and ecological condition, and to adopt 3 superb technology, etc.

Key words: Karst mountains, irrigation and water conservancy, efficiency evaluation, problems and solutions
