农业综合开发的重点是改造中低产田,对于低洼易涝地区是除涝治碱,健全排灌系统。本文分析了农业综合开发工程建设的任务及其精度要求,并对专用图的测绘精度和应用进行了探讨,将二者结合起来进行研究,因而对如何搞好专用图的测绘和如何应用好专用图均具重要参考价值。 The focus of comprehensive agricultural development is to transform medium and low-yielding fields. For the low-lying and flood-prone areas, water and soil erosion control and sound irrigation and drainage systems are well established. This paper analyzes the task of agricultural comprehensive development project and its precision requirements, and the mapping precision and application of special map are discussed, the two are combined to study, so how to do a good job of special map mapping and how to use a good Figure are important reference value.
