    摘要:

    鑒于高標(biāo)準(zhǔn)農(nóng)田工程布局、結(jié)構(gòu)具有自身特殊性以及相較于一般農(nóng)田具有空間形態(tài)上的顯著差異,本研究基于農(nóng)田田塊尺度,以《高標(biāo)準(zhǔn)農(nóng)田建設(shè)通則》為評(píng)價(jià)出發(fā)點(diǎn),從田塊規(guī)模、田塊形態(tài)、農(nóng)田道路、灌排設(shè)施和農(nóng)田防護(hù)等方面構(gòu)建了一套高標(biāo)準(zhǔn)農(nóng)田建設(shè)合規(guī)性評(píng)價(jià)指標(biāo)體系,利用布爾型賦值方式和短板原理綜合評(píng)價(jià)高標(biāo)準(zhǔn)田塊建設(shè)的質(zhì)量和狀況,并以吉林省松原市土地整治項(xiàng)目區(qū)為例進(jìn)行試驗(yàn)實(shí)證。研究表明:從農(nóng)田建設(shè)規(guī)范的內(nèi)涵出發(fā),構(gòu)建的評(píng)價(jià)體系能有效測(cè)度不同維度和不同方面的高標(biāo)準(zhǔn)農(nóng)田建設(shè)效果;提出的方法體系可進(jìn)一步挖掘高標(biāo)準(zhǔn)農(nóng)田建設(shè)工程的短板,為下一步改進(jìn)工程措施和提高建設(shè)的合理性提供依據(jù);試驗(yàn)區(qū)契合與不契合高標(biāo)準(zhǔn)農(nóng)田建設(shè)標(biāo)準(zhǔn)的田塊分別占總面積的78.2%和11.8%。

    Abstract:

    Well-facilitated farmland construction is an important strategy to ensure food safety. It is meaningful for improving regulation efficiency to quickly determine whether farmland construction is of high standard or not. Well-facilitated farmland has its remarkable features in engineering layout and structure,and has distinctive spatial morphology compared with regular farmland. In order to quickly recognize well-facilitated farmland,based on patch scale,a system for identifying spatial pattern was established,considering patch size,patch shape index,spatial relationship of patch with pathway,irrigation channel,drainage and shelter. Using this system,the case of Songyuan land consolidation project located in Jilin Province was looked into, and it was found that 129 patches (78.2% of the total cultivated land area) completely met the criteria of wellfacilitated farmland,and 43 patches can not completely meet criteria. These 43 patches were characterized by the spatial structure below the form requirements for strip farmland,insufficient farmland shelter construction and irrigation facilities. The results indicated that spatial morphology can be regarded as an important criterion for judging whether a farmland was wellfacilitated or not. The morphology can not only help recognize the patches that met the requirement of well-facilitated farmland construction,but also analyze the insufficiencies in constructing a well-facilitated farmland. The research result can provide reference for improving the current regulation system of wellfacilitated farmland construction.
