中文摘要: 种棉土壤适宜性评价是对特定地域土壤适宜棉花生长程度的科学性评价。对研究区土壤是否适宜棉花生长做出定性、定量和定位的评价,不仅可以充分利用资源,实现棉花优质高产,而且基于现有资源和作物生长规律,优化棉花种植的总体布局,达到种棉土壤的可持续利用。本研究以新疆渭干河-库车河三角洲绿洲为例,在田间研究方法的基础上,以ArcGIS9.3为研究平台,采用研究区通过遥感与实地调研得出的各种属性数据和空间数据,以栅格和矢量图层叠加而生成的图斑作为评价单元,确定种棉土壤适宜性评价的影响因子。根据评价单元、评价因子,构建种棉土壤适宜性评价的指标体系。在所构建的评价指标体系的基础上,应用GIS技术,研究种棉土壤适宜性的评价应用模型。最后针对研究区的实际情况,进行种棉土壤适宜性评价的分定等级并绘制专题地图。该研究新疆的棉田优化布局和棉花产业可持续发展重要科学依据。

英文摘要: Cotton soil suitability evaluation is a scientific evaluation of the specific geographic areas of soil suitable for the extent of cotton. Making the qualitative, quantitative and positioning evaluation of soil suitability for cotton not only make full use of resources, achieve high-quality cotton and high-yield, but also can optimize the overall layout of the cotton-growing and sustainable use of cotton soil based on existing resources and crop growth law. In this study, taking Xinjiang Weigan - Kuqa River as an example, on the basis of field research methods and ArcGIS9.3 research platform, firstly, determine the impact of the cotton soil suitability evaluation factor by using the various properties of the data obtained through remote sensing and field research and space polygon data. Then according to the evaluation unit and the evaluation factors, build cotton soil suitability evaluation index system. Based on the evaluation index system built the application model of cotton soil suitability evaluationby using GIS technology,. Finally, the actual situation of the study area, detemine the sub-grade of the cotton soil suitability evaluation and draw thematic maps. This reseach will be important scientific basis for the study of Xinjiang cotton fields distribution and the cotton industry sustainable development.
