综合考虑农田标准化建设中农道建设和土地平整中的土方调配问题 ,按照土方搬运工程量最小、总体最优的原则 ,建立了可用于农田排灌小区规划治理的农道建设与土地平整数学模型。在满足农道及耕区各项技术标准的条件下 ,该模型可自动地划分耕区和确定田面平整高程 ,方便地给出了农道及土地平整工程量。
Considering the problem of earthwork allocation in farmland construction and land leveling in the standardization of farmland, a mathematical model of farmland construction and land leveling that can be used in the planning and management of farmland drainage and irrigation districts was established according to the principle of the least amount of earth moving and the overall optimum. Under the conditions of meeting the technical standards of rural roads and cultivated areas, the model can automatically divide the cultivated area and determine the level elevation of the farmland, and provide the farmland and land leveling works conveniently.
