宁夏农业集约化程度时空评价研究

农业集约化是提高粮食产量的有效途径，我国农业正朝着集约化方向发展。本文在GIS技术的支持下，采用熵值法确定指标权重，通过多目标综合评价模型，对宁夏回族自治区农业集约化程度进行纵向比较和空间差异性分析。结果表明:纵向上基本呈现阶梯状上升的发展趋势；2009年各县（市）农业集约化程度空间差异显著，基本表现出由南向北逐渐升高的分布规律。该评价结果可以为研究区农业生产管理和农业规模化经营提供科学的依据。 

Space-time Evaluation Research on the Degree of Agricultural Intensification in Ningxia Hui Autonomous Region

Agricultural intensification is the effective way of improving grain outputs，and China′s agriculture is moving towards to intensification.In order to alleviate the sharp contradictions between rapid increasing population and relative shortage of the cultivated land resources，agricultural intensification will be the direction of agricultural development in China.With the support of GIS technology，the paper utilized entropy method to determine the index weights，and made use of the multi-objective synthesis evaluation model to analyze the longitudinal comparison and spatial distribution of degree of agricultural intensification in Ningxia Hui Autonomous Region.The results indicated that vertical years basically presented the rising trend in the shape of ladder，in 2009 various counties and cities had significant difference on the degree of agricultural intensification，mainly showing the rising distribution rule from south to north.The evaluation results could provide scientific proofs for agricultural production administration and agricultural scale management in the research area.
