    摘要:

    針對(duì)耕地多功能評(píng)價(jià)供需混淆的問題,,提出了耕地多功能供需理論框架,,從供給和需求兩個(gè)角度構(gòu)建耕地多功能評(píng)價(jià)體系,采用全排列多邊形圖示法計(jì)算耕地多功能指數(shù),,分析了河南省耕地多功能供給需求空間差異,,參考國家戰(zhàn)略需求并以平衡供需為目標(biāo)提出了耕地優(yōu)化路徑。結(jié)果表明:耕地多功能供給表現(xiàn)為其輸出的產(chǎn)品和服務(wù)能力,,耕地多功能需求是指人類對(duì)耕地所提供的各項(xiàng)產(chǎn)品和服務(wù)的消耗量,;供給和需求均可分為生產(chǎn)、經(jīng)濟(jì),、生態(tài),、社會(huì)保障和景觀文化5種功能。2017年河南省耕地多功能供給(多功能指數(shù)為0.678)相較于需求(多功能指數(shù)為0.723)表現(xiàn)出滯后性,,其中僅景觀文化功能為供過于求,,且生態(tài)功能和社會(huì)保障功能供需失衡的城市數(shù)量最多。耕地多功能供給和需求總體呈現(xiàn)西北低,、東南高的空間格局,,豫東南部耕地多功能供需相對(duì)平衡,半山區(qū)耕地多功能供需失衡明顯,。根據(jù)國家戰(zhàn)略規(guī)劃與耕地多功能供需差異,,將耕地優(yōu)化路徑分為功能轉(zhuǎn)化,、供給提升,、耕地儲(chǔ)備3種類型。本研究因地制宜地劃分了耕地利用優(yōu)化類型,,可為實(shí)現(xiàn)區(qū)域耕地“三位一體”發(fā)展提供支撐,。

    Abstract:

    Aiming at the confusion of supply and demand of cultivated land multi-function evaluation, a theoretical framework of multi-function supply and demand of cultivated land was put forward. The index evaluation system was constructed from two perspectives of supply and demand respectively, and the multi-function index of cultivated land was calculated by using the full array polygon graphic method,so as to analyze the spatial differentiation of the multi-functional supply and demand of cultivated land in Henan Province. According to the national strategic demand and taking the balance of supply and demand as the target, the optimal path of the balanced supply and demand of the cultivated land were identified. The results were as follows: the multifunctional supply of cultivated land was the output of its products and services. The multi-functional demand of cultivated land referred to products and services consumed by humans;the multi-functional supply and demand can be divided into five functions, i.e., production, economy, ecology, social security and landscape culture. Compared with the demand (0.723), the multi-functional supply of cultivated land (0.678) in Henan Province showed hysteresis only the landscape function was the mismatch mode of oversupply, and the largest number of cities were the mismatch between supply and demand of ecological function and social security function. The multi-functional supply and demand of cultivated land generally presented the spatial pattern of low in northwest and high in southeast;the multi-functional supply and demand of cultivated land in southeast Henan were relatively balanced;the imbalance of multi-functional supply and demand of cultivated land in mid-levels was significant. According to the matching degree of supply-demand of various functions and national strategic planning, Henan Province can be divided into three optimization paths: functional transformation area, supply promotion area and cultivated land reserve area. The conclusion showed that the types of cultivated land utilization was optimized according to local conditions, and it can provide support for “trinity conservation of cultivated land”.
