    摘要:

    针对耕地多功能评价供需混淆的问题,提出了耕地多功能供需理论框架,从供给和需求两个角度构建耕地多功能评价体系,采用全排列多边形图示法计算耕地多功能指数,分析了河南省耕地多功能供给需求空间差异,参考国家战略需求并以平衡供需为目标提出了耕地优化路径。结果表明:耕地多功能供给表现为其输出的产品和服务能力,耕地多功能需求是指人类对耕地所提供的各项产品和服务的消耗量;供给和需求均可分为生产、经济、生态、社会保障和景观文化5种功能。2017年河南省耕地多功能供给(多功能指数为0.678)相较于需求(多功能指数为0.723)表现出滞后性,其中仅景观文化功能为供过于求,且生态功能和社会保障功能供需失衡的城市数量最多。耕地多功能供给和需求总体呈现西北低、东南高的空间格局,豫东南部耕地多功能供需相对平衡,半山区耕地多功能供需失衡明显。根据国家战略规划与耕地多功能供需差异,将耕地优化路径分为功能转化、供给提升、耕地储备3种类型。本研究因地制宜地划分了耕地利用优化类型,可为实现区域耕地“三位一体”发展提供支撑。

    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”.
