基于GIS的农用地质量综合评价方法研究--以无锡市马山区为例

根据农用地质量综合评价因素所具有的空间特征和相关性,采用GIS技术和方法,对评价区农地的自然条件和社会环境信息以一定格式输入、存储、检索和操作,并根据GIS空间分析的类型和功能,结合模糊综合评判模型等数学方法,提出农用地质量综合评价系统的框架模型。并以无锡市马山区为例,开展了评价因子的量化、空间分析、等级划分、面积量算及评价图件输出等功能的试验,为进一步构建集成的土地评价信息系统原型奠定了基础。

SYNTHETIC EVALUATION METHOD OF FARMLAND QUALITY BASED ON GIS:A CASE STUDY IN MASHAN DISTRICT, WUXI

Based on the spatial characteristics and correlations of the impact factors in the synthetic evaluation of farmland quality and supported by computer technology, a framework model or the synthetic evaluation system or farmland quality is put forward for data input,storage,retrieval and operation of the natural conditions and social environment of the farmland in the evaluation regions,which is based on the types and functions of GIS spatial analysis and combined with fuzzy synthetic evaluation models.Furthermore, a case study is carried out in Mashan District, Wuxi, Jiangsu Province, and some experiments are undertaken on the functions of quantification of the evaluation factors, spatial analysis, grade division, area measurement and calculation,evaluation chart output, etc,which can provide the basis for developing land evaluation information system.
