摘要: 研究高标准农田建设对耕地质量等级的影响情况,分析各项评价指标因素在高标准农田建设前后的变化情况和对耕地质量的贡献程度,为余江区合理规划建设高标准农田、提高耕地质量提供科学参考和技术依据。以余江区2015年和2020年期间建设的高标准农田为例,通过RS技术和ArcGIS手段获取评价指标指数,从自然地理、土壤状况和人为管理3个角度构建评价指标体系,采用CRITIC法确定各指标权重,对高标准农田建设前后耕地质量进行评价,计算各指标贡献值。高标准农田建成后,总体耕地质量得到提升,Ⅰ级耕地面积增加1 165.59 hm2,增加21个百分点,平均耕地质量等级提升0.79个等级;从各行政乡镇提升情况来看,各地区均有提升,其中平定乡提升最多,提升0.75个等级,变化率为32.61%。在建设过程中,土壤水分指数贡献程度最高,耕地等级提升贡献值(CG)为0.244,贡献程度达30.96%,变化率为31.91%。余江区耕地质量等级在高标准农田建成后有较大提升,其中水利设施的贡献程度最高,在建成前后代表该方面指数的提升程度也最为明显。

Abstract: This paper investigated the impact of the construction of high-standard farmland on the quality level of cultivated land, analyzed the alterations of each evaluation index factor before and after the construction of highstandard farmland and the degree of contribution to the quality of cultivated land, and offered scientific references and technical bases for the rational planning and construction of high-standard farmland and the improvement of the quality of cultivated land in Yujiang District. Taking the high-standard farmland constructed in Yujiang District during 2015 and 2020 as an example, the evaluation index was obtained through RS technology and ArcGIS means, and the evaluation index system was constructed from three aspects such as physical geography, soil condition and human management. The CRITIC method was employed to determine the weight of each index, and the quality of cultivated land before and after the construction of high-standard farmland was evaluated. The contribution value of each indicator was calculated. After the construction of high-standard farmland, the overall quality of cultivated land was enhanced, the area of grade Ⅰ arable land increased by 1165.59 hm2, with an increase of 21 percentage points, and the average quality level of cultivated land rose by 0.79 levels. From the improvement situation of various administrative townships, all regions witnessed an improvement, among which Pingding Township had the most significant improvement, with an increase of 075 levels and a change rate of 3261%. During the construction process, the soil moisture index contributed the most, the contribution value (CG) of cultivated land grade improvement was 0.244, the contribution degree was 30.96%, and the change rate was 31.91%. The quality level of cultivated land in Yujiang District was improved significantly after the completion of high-standard farmland, in which the contribution of water conservancy facilities was the highest, and the improvement of this index was also the most notable before and after the completion.

Key words: Yujiang District, high standard farmland, cultivated land quality, grade evaluation, soil moisture
