摘要

基于对耕地质量和耕地产能的进一步认识,从耕地的物理、化学、生物、环境和工程5个维度出发,采用特尔斐法确定评价指标和权重,再运用加权求和法和影响因素逐级修正法构建模型,对广东省新兴县的耕地质量和耕地产能状况进行评价。结果表明:新兴县耕地质量评价结果为良等、中等和低等,主要为低等,耕地产能评价结果介于7～11等,主要为8、9等;耕地质量指数(不计入生物特性)和国家自然等指数、耕地产能指数和国家利用等指数均呈极显著相关,耕地质量等别和国家自然等、耕地产能等别和国家利用等之间衔接良好;与农用地质量分等体系相比,采用该研究构建的评价体系对整治项目建设前后耕地等别变化进行分析,更能体现土地整治工程对耕地等别的提升效果。构建的县域耕地质量和耕地产能评价体系紧密结合区域实际,评价结果与农用地质量分等结果衔接较好,且能够相对较明显地体现土地整治项目在耕地质量和耕地产能方面的功效,可为土地整治、耕地占补平衡和基本农田保护等土地管理工作提供依据。
        The cultivated land quality and cultivated land productivity status of Xinxing County,Guangdong Province were evaluated in this paper.The theoretical basis of the evaluation was a further understanding of the quality and productivity of cultivated land.The evaluation indicators included the physical,chemical,biological,environmental and engineering dimensions of cultivated land.The evaluation indicators and weights were determined based on the Delphi method.The construction of the evaluation model was a combination of the weighted summation method and the stepwise correction method of the influencing factors.The results showed that:the evaluation result of cultivated land quality in Xinxing County were good,medium and low,mainly low,and the evaluation result of cultivated land productivity were between 7 and 11,mainly 8 and 9;the cultivated land quality index(excluding biological characteristics)was significantly correlated with the national natural quality index,the cultivated land productivity index was also significantly correlated with the national utilization index.The connection between the quality level of cultivated land and the national natural quality level,the cultivated land productivity level and the national utilization level were good.The evaluation system constructed in this study and the agricultural land quality grading system were respectively used to evaluate the cultivated land quality and cultivated land productivity before and after the construction of renovation projects.The comparative analysis of the results showed that the former can improve the responsiveness of various engineering measures in the remediation project,and reflect the improvement effect of the land remediation project on cultivated land.The evaluation systems which were established to evaluate the quality and productivity of cultivated land are closely related to the actual situation in the study area,and the evaluation results in this study are well connected with the grading results of agricultural land quality.They also can more clearly show the effect of the land improvement project on cultivated land quality and cultivated land productivity.The results can provide basis for land reclamation,cultivated land occupation and supplementary balance,basic farmland protection and other related land management work.
