基于耕地质量等级与限制因子的耕地质量提升分区以安徽省青阳县为例

Zoning of Cultivated Land Quality Improvement Based on Cultivated Land Quality Grade and Limiting Factors: A Case Study of Qingyang County in Anhui Province

  • 摘要: 了解耕地质量现状是耕地质量提升的基础,明确限制因子是进行耕地改良的关键。利用空间自相关分析和障碍度模型,揭示青阳县耕地质量现状及空间分布特征,识别地块限制因子类型并判定改良难度,在此基础上划分耕地质量等级提升分区。结果表明:研究区耕地质量等级以4~6等地为主,呈现北高南低的空间分布特征,且表现出较强的空间相关性;受地形部位、灌溉能力限制的耕地分布面积最大,限制因子改良难度整体呈现南高北低的态势;基于耕地质量评价与限制因子诊断结果,将青阳县耕地划分为重点提升区、综合提升区、一般提升区、保护提升区和限制提升区,针对分区特点提出相关策略。研究结果可为耕地质量提升工程的重点和方向提供依据。

     

    Abstract: Understanding the status quo of cultivated land quality is the basis for improving the quality of cultivated land, and defining the limiting factor is the key to improving cultivated land. Using spatial autocorrelation analysis and obstacle degree model to reveal the status quo and spatial distribution characteristics of cultivated land quality in Qingyang County, identify the types of land block constraints and determine the difficulty of improvement, and on this basis, divide cultivated land quality grade improvement zones. The results show that: The quality grade of cultivated land in the study area was mainly in grades 4 ~ 6, showing the spatial distribution characteristics of high in the north and low in the south, and showing strong spatial correlation. The distribution area of cultivated land limited by terrain location and irrigation capacity is the largest, and the difficulty of improving the limiting factor is generally higher in the south and lower in the north. Based on the results of cultivated land quality evaluation and restriction factor diagnosis, the cultivated land in Qingyang County was divided into key promotion areas, comprehensive promotion areas, general promotion areas, protected promotion areas and restricted promotion areas, and the relevant strategies were proposed according to the characteristics of these areas. The research results can provide a basis for the focus and direction of the cultivated land quality improvement project.
