摘　　要：在农业生产适应性评价阶段,对影响农业生产的因素进行全面分析是保障评价结果可靠性的基础。本文以某土地资源为研究对象,在初步了解其基础信息后,分别从土地资源特征、水文条件、气候条件以及生态环境4个方面对研究区土地资源现状进行分析,构建了以单个指标为核心的等级划分标准,借助DEM(digital evaluation model,数字高程模型)确定了不同划分尺度下的土地面积大小。通过融合土地资源特征、水文条件、气候条件的分析结果,构建了评价矩阵,利用生态环境对评价结果进行修正,实现对农业生产适应性的客观评价,得到生产适宜区的面积为370797.30 hm^(2),占评价面积的51.53%;通过叠加不同影响因素的生产条件,得到研究区域的承载规模,面积为664944.43 hm^(2),占评价面积的92.42%。In the adaptability evaluation stage of agricultural production,a comprehensive analysis of the factors affecting agricultural production is the basis for ensuring the reliability of the evaluation results.This paper took the actual land resources of a certain area as the research object,and had a preliminary understanding of its basic information.Then,it analyzed the present situation of land resources in the research area from four aspects(land resource characteristics,hydrological conditions,climatic conditions and ecological environment),and constructed a grading standard with a single index as the core.With the help of DEM(digital evaluation model),the land area under different division scales was determined.By integrating the analysis results of land resource characteristics,hydrological conditions and climatic conditions,an evaluation matrix was constructed,and the evaluation results were modified by using ecological environment to achieve an objective evaluation of agricultural production adaptability.The area of the suitable production area was 370797.30 hm^(2),accounting for 51.53%of the evaluated area.By superimposing the production conditions of different influencing factors,the carrying capacity of the research area was obtained,with an area of 664944.43 hm^(2),accounting for 92.42%of the evaluated area.
