    摘要:

    高標準農(nóng)田建設(shè)是優(yōu)化農(nóng)田空間布局,,改善耕地基礎(chǔ)設(shè)施,,提高耕地質(zhì)量和綜合生產(chǎn)能力的重要舉措,。而科學(xué)合理地劃定建設(shè)區(qū)域是高標準農(nóng)田建設(shè)的重要環(huán)節(jié)。以河南省焦作市為例,,構(gòu)建了耕地綜合質(zhì)量評價體系,并通過層次分析法對各個評價指標賦權(quán),。再結(jié)合理想點逼近法和局部空間自相關(guān)分析對高標準農(nóng)田建設(shè)分區(qū)及時序提出了方案,。研究結(jié)果表明:焦作市耕地整體質(zhì)量較好,且在空間分布上體現(xiàn)出了較強的正相關(guān)性,;利用局部空間自相關(guān)分析可將耕地分為4個高標準農(nóng)田建設(shè)區(qū)域,。

    Abstract:

    Well-facilitied capital farmland construction is an important measure to optimize the farmland spatial layout and improve the farmland infrastructure, and it also plays an important role in guaranteeing national food safety and modern agriculture development. Moreover, it could help to increase the cultivated land quality and productive capacity. Scientific and reasonable zoning of the construction area is an essential step of the construction itself. Therefore, taking Jiaozuo City, Henan Province as an example, the comprehensive quality evaluation system of cultivated land was built, and then the weight of each evaluation index was calculated by means of analytic hierarchy process (AHP). Then through coupling with technique for order preference by similarity to an ideal solution (TOPSIS) and local indicators of spatial association (LISA), some suggestions for construction of well-facilitied capital farmland zoning and timing sequence were put forward. The result showed that the overall quality of cultivated land in Jiaozuo City was good and it showed a strong positive correlation in spatial distribution. The area of cultivated land belonging to positive correlation reached 61.665% of the total cultivated land area. Besides, cultivated land quality attributes and spatial attributes were uniform. Using local indicators of spatial association, cultivated land can be divided into four well-facilitied capital farmland construction areas. According to the characteristics of different spatial autocorrelation types, the corresponding remedial measures and construction timing were put forward. With comprehensive consideration of the cultivated land in all kinds of properties, the research can provide basis for construction of wellfacilitied capital farmland planning.
