    摘要:

    我国中低产田分布广泛,产能提升潜力巨大,提高中低产田产能对于保障粮食安全、实现联合国可持续发展目标具有重要的意义。明确中低产田的质量等级、面积与空间分布,开展中低产田评价相关研究是中低产田改造的前提和基础。本文系统梳理了中低产田的概念 、评价指标和主要评价方法,分析了中低产田概念的演变过程,在此基础上探讨了我国中低产田评价的主要不足和发展趋势。现有的中低产田概念以中低产田数量和质量评价为主、对生态功能和可持续发展能力的研究仍较少,指标体系与评价方法尚不统一,中低产田高分辨率、长时序的时空动态变化情况尚不清楚。未来中低产田评价相关研究可围绕“数量、质量和生态”三个方面,开展多尺度中低产田评价指标体系构建、多源数据融合、创新中低产田评价方法、中低产田时空变化分析等相关研究,实现不同尺度上的中低产田动态变化分析,探索绿色高产高效的耕地产能提升路径,保障粮食安全、促进可持续发展目标的实现。

    Abstract:

    China’s medium-low yield fields are widely distributed and have great potential for land productivity improvement. Improving the land productivity of medium-low yield fields is of great significant for ensuring food security and achieving sustainable development goals (SDGs). Assessing the quality and spatial distribution of medium-low yield fields is the prerequisite and basis for land improvement. This paper systematically reviewed the concept, evaluation indicators, and main evaluation methods of medium-low yield fields. Based on the research status of medium-low yield fields, this paper discusses the main problems and development trends of the assessing of medium-low yield fields in China. The existing concepts of medium-low yield fields focus on the area and quality of medium-low yield fields, and there are few studies on ecological aspect and sustainable development abilities. Furthermore, the indicators system and evaluation methods for medium-low yield fields are not uniform. In the future, the medium-low yield fields assessment should consider quantity, quality, and ecology aspects. The medium-low yield fields assessment should be focused on the multi-scale assessment indices system construction and multi-source data fusion assessment methods innovation. Analyzing the spatial and temporal pattern of medium-low yield fields in different scales is helpful to explore ways to increase the productivity of green, high-yield, and efficient agricultural production, ensure food security, and promote the realization of SDGs
