民以食為天，食以谷為本，谷以地為源，耕地在保障國(guó)家糧食安全中發(fā)揮重要作用。由于我國(guó)人多地少和區(qū)域差異顯著的基本現(xiàn)狀，加之家庭聯(lián)產(chǎn)承包責(zé)任制的推廣、土地均分以及公平訴求導(dǎo)向下耕地肥瘦搭配的分配方式，使得大量耕地地塊面積狹小、插花分布。21世紀(jì)以來(lái)，城鎮(zhèn)化發(fā)展導(dǎo)致土地供需矛盾加劇，近郊耕地細(xì)碎化更為明顯。諸如以上自然或人為原因?qū)е赂丶?xì)碎化成為我國(guó)農(nóng)業(yè)生產(chǎn)中普遍存在的問(wèn)題。在特定的歷史時(shí)期，耕地細(xì)碎化在豐富農(nóng)業(yè)生產(chǎn)結(jié)構(gòu)、增加農(nóng)戶(hù)收入、降低經(jīng)營(yíng)風(fēng)險(xiǎn)等方面發(fā)揮積極作用，但隨著農(nóng)業(yè)現(xiàn)代化的發(fā)展，耕地細(xì)碎化成為推進(jìn)耕地規(guī)模經(jīng)營(yíng)的障礙，不利于農(nóng)業(yè)生產(chǎn)效率的提高[3。新時(shí)期土地整治的內(nèi)涵實(shí)現(xiàn)從增加耕地?cái)?shù)量為主向“數(shù)量管控、質(zhì)量管理、生態(tài)管護(hù)\"三位一體綜合管理轉(zhuǎn)變4。加強(qiáng)耕地細(xì)碎化問(wèn)題研究，對(duì)于引導(dǎo)耕地綜合整治、提高耕地質(zhì)量、推進(jìn)耕地規(guī)模經(jīng)營(yíng)、提升耕地利用效率具有重要的理論和實(shí)踐意義。

目前，關(guān)于耕地細(xì)碎化的研究多集中于耕地細(xì)碎化的理論解析、影響因素、測(cè)度評(píng)價(jià)等方面[5-8]。我國(guó)耕地細(xì)碎化問(wèn)題最早由Buck等提出，陳培勇等[]從多個(gè)角度探討了耕地細(xì)碎化的具體內(nèi)涵，其中區(qū)域尺度下的耕地細(xì)碎化體現(xiàn)為受地形地貌特征、自然資源稟賦、經(jīng)濟(jì)社會(huì)發(fā)展等自然或人為因素導(dǎo)致的耕地資源在質(zhì)量、分布、集聚水平上的空間差異?！?br>
