摘要： 为了量化分析和分类评价农业生态气候资源 ,根据西北地区 (甘宁青 )165个气象台站多年平均的气候资料 ,采用农业生态气候适宜度的动态模型 ,首先计算了农业生态气候的资源指数、效能指数和利用系数 ;然后通过对多年逐月平均效能指数的模糊动态聚类 ,划分出农业生态气候资源的12个类型并进行了相应评价 ,结果表明农业生态气候的资源潜力、匹配状况和利用程度具有明显的地域分异特征 ,进而在此基础上提出了开发利用农业生态气候资源的若干建议

Abstract: In order to analyze quantitatively and evaluate classifiably agro ecoclimatic resources,based on average data of multiple years from 165 meteorological stations of Northwest China(Gansu,Ningxia and Qinghai),resource indices Cr,efficiency indices Ce and utility coefficient K were calculated by applying the dynamic models of agro ecoclimatic suitability degree.Then,based on month to month average data of multiple years of efficiency indices Ce,twelve types of agro ecoclimatic resources were identified through the analysis of fuzzy cluster.The results indicated that latent potentialities,matching condition and utility degree of agro ecoclimatic resources have obvious characteristics of spatial differentiation.On the basis of the calculation results,the suggestions about exploitation and utilization of the agro ecoclimatic resources in Northwest China(Gansu,Ningxia and Qinghai)are put forward.
