中国北方农牧交错带土地适宜性评价研究(英文)

Study on Land Suitability Evaluation in the northern China Crop-pasture Band

集合限制因子法和综合指数和法,针对中国北方农牧交错带,建立了该区耕地适宜性评价的指标体系,筛选出评价的主导因子,采用专家打分法和权重法对所有地块的耕地适宜性进行了评价。结果表明,研究区绝大部分区域是不适合于农业耕种,较适宜于农业耕种的区域面积仅占总面积的8.45%,且主要分布于东南和西南2个区域,还有东北部地区,不适宜农业耕种的地区主要分布于东部的中间部位、中部的广泛地区以及西部地区。

Basing on the limiting factor method and Composite Index method,for the northern China crop-pasture band,the authors established the system of evaluation index,and abstracted the dominant factor,then through applying expert grade and weighing way the suitability of grids are evaluated,the results showed that：without the input of a large number of cash,most of the area was not suitable for farming,and more appropriate area for farming was only 8.45% of total area,mainly located in the southeast and southwest of the study area,followed by the study area in the northeast,areas that was not suitable for farming mainly in the middle of the east,large areas of central and western regions.
