基于GIS的棉花土地适宜性评价——以新疆兵团农八师148团8连为例

Evaluation of the Suitability of Land Resources for Cotton Based on GIS Technology——A Case Study in Xinjiang Production and Construction Corps

为了评价某个区域的土地适宜棉花生长的程度,本文进行了基于GIS的棉花土地适宜性评价的研究。该研究选取新疆农八师148团8连为研究区域,采用ArcGIS作为主要分析工具,建立了包括土地评价单元划分、评价因子选取、权重的确定以及土地定级的通用模型,形成一个快速、简易、实用的土地评价流程。评价结果显示:研究区61%的土地适宜棉花生长,含盐量为限制棉花生长的主要因素,可通过土壤盐渍化改造提高土地的利用效益。

In order to evaluate the land suitability for cotton, the research which makes use of ArcGIS establishes the common model including the partition of evaluation unit, the selection of evaluation factors,the determination of the weight,and forms a fast,simple and practical evaluation process. The results illustrate that 61 percent of the study area is suitable for cotton,and the content of salt is the main limiting factor of the cotton＇s growth.
