利用数学曲面进行土地整理设计

Land Consolidation Design Methods Using Mathematical Surfaces

土地整理是增加耕地面积,提高土地质量,实现农村经济社会发展的重要举措;同时地面整理也是防止土壤侵蚀的重要措施之一。土地整理是一个需要多项技术支持的综合工程。与水田相比,耕地的地面形状比较复杂,因此地块设计的地形数据和设计方法也繁多。耕作田块是耕作的基本单元,田块设计包括田块的方向、形状、规模等因素,在设计当中要采取智能化、简单化、精确化的算法,以便适应多种多样的地形以及地质条件。该文在田块整理设计中利用一般n次曲面方程的求解算法提出了适应各种地形条件和整理对象要求的田块整理设计面确定方法。

Land consolidation is to increase arable land and improve land quality,an important measure to achieve economic and social development in rural areas;simultaneously the ground finishing is one of the important measures to prevent soil erosion.In addition,land consolidation is a comprehensive engineering requiring a number of technical supports.Compared to paddy field ground,arable land shape has much more complex ranges of terrain data and design methods whereby its plot design. The farming plots of land terraces are the basic unit for land farming.Plots design includes plots direction,shape,size and other factors.Designs should be taken as intelligent,simplified,accurate algorithm,in order to adapt a wide variety of terrain and geological.Plots finishing design with general n - th surface equation solving algorithm can adapt to the requirements of the various terrain conditions and determine the method to organize the objects of the finishing design surface.
