一、引言平整土地是农田基本建設的一个重要方面,它对节約灌溉用水,扩大灌溉面积,洗碱保苗,提高机耕效率等方面均起着重大的作用。随着水利建設的不断扩大,需要平整的土地也将增多。鉴于这工程是大面积进行的,因此若能提出較合理的方案,則将会为国家节省大批的資金和劳力,故此问題是值得研究。怎样才能使这工程进行得多快好省呢?做好測量規划設計是其中重要的一环。本文拟重点討論如下三个方面的問題:(一)平整土地对測量提出的精度要求?(二)規划方案怎样較为合理?(三)經济运距如何确定?
I. INTRODUCTION Leveling the land is an important aspect of the basic farmland construction. It plays an important role in saving irrigation water, expanding the irrigated area, sowing alkali and protecting seedlings, and increasing the efficiency of farming. With the continuous expansion of water conservancy construction, there will also be more land to be leveled. Given that this project is carried out on a large scale, if a more reasonable plan can be put forward, it will save the country a large amount of funds and labor. Therefore, this issue is worth studying. How can we make this project faster? It is an important part of planning and designing for measurement. This article will focus on the following three issues: (a) the accuracy of the proposed leveling of the measurement proposed by the land? (b) how is the planning plan more reasonable? (c) how to determine the economic distance?
