中文摘要:
      当前,我国农用地评价理论体系日趋成熟,发布了农用地分等技术规程,构建了基于农用地自然、经济 和社会要素的评价技术体系,为耕地质量等别评定提供了理论基础与实践依据。由于农用地分等技术规程是 基于区域平衡与结果可比性制定的,确定的评价单元比较具象、选取的评价指标比较普适、指标值测算量化度 不够,由此开展的耕地质量评定难以体现耕地地块在空间上的质量差异。鉴于此,基于耕地质量分等因素在地 理实体上呈现的空间异质性,研究了耕地质量分等因素空间异质性表达和标准化方法,并以黄陂区 2017 年度 全域耕地为评价对象进行了实证,表明该方法更科学、合理和精准,可有效指导微观尺度的耕地质量等别评价 和监测工作。
英文摘要:
      At present,the theoretical system of agricultural land evaluation in China is becoming more and more mature. The technical regulations of agricultural land classification have been released,and the evaluation technical system based on the natural,economic and social factors of agricultural land has been constructed,which provides a theoretical and practical basis for the evaluation of cultivated land quality. Since the technical regulations for agricultural land classification were formulated based on the regional balance and the comparability of results,the identified evaluation units were concrete,the selected evaluation indicators were universal,and the index values were not sufficiently quantified.Therefore,it was difficult for the cultivated land quality assessment to reflect the spatial quality differences of cultivated land plots. In view of this,based on the spatial heterogeneity of cultivated land quality classification factors in geographic entities,this paper studied the spatial heterogeneity expression and standardization methods of cultivated land quality classification factors,and conducted a demonstration with the entire cultivated land in Huangpi District in 2017 as the evaluation object. It showed that the method was more scientific,reasonable and accurate,and could effectively guide the micro-scale cultivated land quality evaluation and monitoring.
