    摘要:

    耕作便利是表征農(nóng)田綜合質(zhì)量的重要因素。為準(zhǔn)確反映現(xiàn)代農(nóng)業(yè)發(fā)展對(duì)耕作便利條件的要求,基于農(nóng)業(yè)機(jī)械效率視角界定農(nóng)田耕作便利度,進(jìn)而構(gòu)建定量綜合評(píng)價(jià)模型,,并在華北平原項(xiàng)目區(qū)開展實(shí)證分析,。結(jié)果表明:新界定的耕作便利度強(qiáng)化了農(nóng)業(yè)機(jī)械耕作效率的影響,,包括田間作業(yè)效率和機(jī)械通行效率兩方面,。明確了機(jī)械化耕作背景下的連片度,、耕作距離和田間道路通達(dá)度3個(gè)關(guān)鍵指標(biāo)的內(nèi)涵與快速獲取方法,,為準(zhǔn)確評(píng)價(jià)耕作便利度奠定了基礎(chǔ),。耕作便利度評(píng)價(jià)結(jié)果顯示:研究區(qū)82.41%的耕地處于非常便利和比較便利的級(jí)別,平均地塊面積大,,集中連片且交通便利,,是發(fā)展高效農(nóng)業(yè)、推廣機(jī)械化耕作的適宜區(qū)域,;一般便利和不便利級(jí)別的田塊平均面積較小,,分布分散且遠(yuǎn)離居民點(diǎn),機(jī)械耕作效率較低,,不利于發(fā)揮規(guī)模效益,。該研究可為耕地質(zhì)量評(píng)價(jià)、高標(biāo)準(zhǔn)農(nóng)田建設(shè)項(xiàng)目選址等提供技術(shù)支持,。

    Abstract:

    Farming convenience degree (FCD) is an important feature of cultivated land. In order to accurately characterize all requirements of modern agriculture for FCD, the definition and its meaning of FCD were introduced. Then, a systematic and comprehensive evaluation model was constructed and applied in a project area of Dingzhou City in Hebei Province. The results showed that the newly defined FCD put farming efficiency on an importance place, which consisted of field work efficiency and traffic efficiency. Three key indexes were thoroughly studied, including connective degree, field road accessibility and farming distance. Their meaning and acquisition method offered the foundation to obtain FCD accurately. The evaluation results showed that the FCD condition of farmland in the study area was good overall. Based on the comprehensive evaluation score, the farm units were divided into four levels. Among that, totally 82.41% of all farmland area was at the level of very convenient or more convenient. These kinds of units mainly had the feature of convergent distribution and large average land area, and also distributed in the area close to roads. It was the appropriate area for developing high-efficiency agriculture and spreading mechanized farming. On the contrary, it was difficult to exert scale benefit and mechanical tillage for farmland of the grades like general convenient and not convenient, because of their small units and scattered distribution. The research can provide technical support and method reference for the project selection and performance evaluation for well-facilitated farmland as well as the evaluation of cultivated land quality.
