节水灌溉工程的适宜性研究

The suitability of water-saving irrigation projects

以阿勒泰地区富蕴县实际节水灌溉工程为例,通过构建节水灌溉工程适宜性评价体系,对比分析在不同影响因素作用下,旋转式喷灌技术、绞盘式喷灌技术、平移式喷灌技术、滴灌技术4种节水灌溉技术的优劣,通过对比分析政策与农业发展、农作物与地形地势匹配度、灌溉覆盖范围与灌溉均匀程度、年度运维费用与节水性能等方面的影响因素,最终得出适宜性由好到差的节水灌溉方式为:旋转式喷灌技术、平移式喷灌技术、绞盘式喷灌技术、滴灌技术。本研究成果可以为其他节水灌溉工程适宜性研究提供参考。

This paper takes the actual water-saving irrigation project in a certain area of fuyuan County Altay Region as an example.By constructing a water-saving irrigation project suitability evaluation system,it compares and analyzes the rotating sprinkler irrigation technology,winch sprinkler irrigation technology,translational sprinkler irrigation technology,drip irrigation under the action of different influencing factors.The pros and cons of the four water-saving irrigation technologies,through comparative analysis of policy and agricultural development,crops and topography matching degree,irrigation coverage and irrigation uniformity,annual operation and maintenance costs and water-saving performance and other factors,finally get the water-saving irrigation methods with suitability ranging from good to poor are:rotary sprinkler irrigation technology,translational sprinkler irrigation technology,winch sprinkler irrigation technology,and drip irrigation technology.The research results of this study can provide references for the suitability research of other water-saving irrigation projects.
