摘要
山地村域耕地质量评价对山地耕地资源的优化利用、综合生产能力的提高、质量退化的遏制等具有重要的现实意义。根据地块尺度对山地村域耕地质量的影响,构建基于地块尺度耕地质量评价方法体系。选取地块坡度、地块面积、耕作高差、耕作距离作为评价指标,进行山地村域耕地质量评价研究。结果表明,研究区总体耕地质量较差,一等耕地仅占总耕地面积的4.37%;二、三、四等耕地的面积所占比例较大,占耕地总面积的87.64%。在耕地质量评价结果分析基础上,为基本农田划定、耕地利用结构调整等提出建议。
The evaluation of cultivated land quality in mountainous villages is very important to the optimal utilization of cultivated land,to the improvement of productivity,and to the prevention of land degradation. In this paper,we established an evaluation system of cultivated land quality in mountainous villages based on plot scale,with the slope,the area,the height difference and the tillage distance as the evaluation indexes of cultivated land quality.The results showed that,the cultivated land quality in the target area was poor,with first-class cultivated land accounting for only 4. 37 % of the total cultivated land area,and second-,third-and fourth-class cultivated land accounting for 87. 64 %. Based on the evaluation results,we put forward some advices for the farmland division and adjustment of cultivated land use structure.
