同仁市地貌復(fù)雜多樣,日照時數(shù)長,氣溫日較差大,降水量差異大[1],春小麥作為同仁市最重要的農(nóng)作物之一,其產(chǎn)量與質(zhì)量對當(dāng)?shù)剞r(nóng)業(yè)發(fā)展會有一定影響,在統(tǒng)籌考慮多種區(qū)劃因素的基礎(chǔ)上研究同仁市春小麥綜合區(qū)劃[2]可以進一步對當(dāng)?shù)刈魑锷a(chǎn)進行合理規(guī)劃,科學(xué)安排農(nóng)業(yè)生產(chǎn),促進農(nóng)村經(jīng)濟發(fā)展和農(nóng)牧民增收,推動農(nóng)業(yè)生產(chǎn)向高產(chǎn)、高效、高精準化的方向發(fā)展[3]。
近年來,國內(nèi)外針對農(nóng)作物種植區(qū)劃的研究不斷發(fā)展,美國、法國、日本等發(fā)達國家的農(nóng)業(yè)區(qū)劃工作經(jīng)歷了相當(dāng)長的發(fā)展過程,已經(jīng)形成了一套相對成熟的理論方法體系和經(jīng)驗做法[4]。……
