    摘要:

    以修正平面法作為平地工程優(yōu)化設(shè)計(jì)方法，開發(fā)具有田面高程數(shù)據(jù)錄入與統(tǒng)計(jì)分析、田面微地形表述、平地土方量估算等多功能的農(nóng)田土地精平工程優(yōu)化設(shè)計(jì)與評(píng)價(jià)軟件，并基于土地精平田面高程實(shí)測(cè)數(shù)據(jù)，對(duì)比評(píng)價(jià)3種數(shù)據(jù)網(wǎng)格插值計(jì)算方法的適用性。研究結(jié)果表明，基于3種插值方法獲得的田面相對(duì)高程網(wǎng)格化數(shù)據(jù)都可用來描述田面微地形的整體分布狀況，其中根據(jù)Kriging插值法得到的田面相對(duì)高程插值估算精度相對(duì)較高，據(jù)此估算的土地精平挖、填方量之間的差異和土方總量接近實(shí)際狀況，可優(yōu)先應(yīng)用于土地精平工程優(yōu)化設(shè)計(jì)工作中。

    Abstract:

    A design and evaluation software for precision farm land levelling engineering was developed with the application of modified plane method. The software has different functions such as farm land elevation data input and statistic analysis, description of microtopography conditions as well as estimation of earthwork. The application effects of three different interpolated methods on software were evaluated based on field data. The results showed that three interpolated methods could be used to produce grid elevation data in farm land and give out the general description of surface condition. However, the Kriging interpolated method gave out the best estimations for both grid elevation data and the earthwork volume. It is suggested that the Kriging interpolated method is applied in designing for farm land precision land levelling engineering. 
