摘要: 通过2022年河北省耕地质量评价项目,对宁晋泊—大陆泽低平原区八个县的耕地质量监测点数据进行汇总分析,对该区域耕地质量与土壤养分状况进行评价。利用网格法均匀布置样点评价单元,五点法采取样地表层土壤(0~20 cm)的耕层土样,按照土壤检测系列标准开展化验,参照农业农村部《全国耕地质量等级评价指标体系》确定指标权重,对有机质、全氮、有效磷、速效钾数值型指标通过建立函数关系确定隶属度,对其他概念性指标,采用特尔斐法专家打分给出隶属度,采用累加法计算耕地质量综合指数,得出耕地质量等级。结果表明:该区耕地质量平均等级为3.51等,其主要耕地等级为三、四等级地,且三等级地耕地为主体,面积为140191 hm2,占该区总耕地面积的49.44%。该区耕地养分整体水平较高,均在三级以上,各养分在区域内均匀分布,有机质、全氮、有效磷、速效钾各养分极大值出现在古大陆泽洼淀区域周边。通过对灌溉保障、耕层质地及构型影响、有机质含量储备等耕地质量评价影响因素的分析,提出维持该地区耕地质量等级的措施建议,为河北省内其他低平原地区开展土壤养分监测、耕地质量提升、保护生态平衡和维持农业可持续发展提供参考。

Abstract:

Through the 2022 Hebei Province Farmland Quality Evaluation Project, data from farmland quality monitoring points in eight counties of the Ningjinbo-Daluze low plain area were summarized and analyzed to evaluate the quality of farmland and soil nutrient status in the region. Using the grid method to evenly arrange sample evaluation units, the five-point method was adopted to collect cultivated soil samples from the surface layer (0-20 cm), and laboratory tests were conducted according to the soil testing series standards. Referring to the National Farmland Quality Grade Evaluation Index System of the Ministry of Agriculture and Rural Affairs, the weight of the indicators was determined. For numerical indicators of organic matter, total nitrogen, available phosphorus, and available potassium, the membership degree was determined by establishing functional relationships. For other conceptual indicators, the Delphi method expert scoring was used to give the membership degree, and the cumulative method was used to calculate the comprehensive index of arable land quality to obtain the arable land quality grade. The results showed that the average quality grade of cultivated land in the area was 3.51, with the main cultivated land grades being third and fourth grade. The third grade cultivated land was the main body, with an area of 140191 hm2, accounting for 49.44% of the total cultivated land area in the area. The overall level of nutrients in the cultivated land in this area was relatively high, all of which were above level three. Nutrients were evenly distributed within the region, and the maximum values of organic matter, total nitrogen, available phosphorus, and available potassium appeared around the ancient Daluze marsh land. By analyzing the factors affecting the quality evaluation of cultivated land, such as irrigation guarantee, the texture and configuration of the plow layer, and the reserve of organic matter content, measures and suggestions for maintaining the quality level of cultivated land in the region were proposed, providing reference for soil nutrient monitoring, improving cultivated land quality, protecting ecological balance, and maintaining sustainable agricultural development in other low plain areas in Hebei Province.
