摘要/Abstract

摘要： 为了定量分析和分类评价农业生态气候资源,根据甘肃省86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,计算了甘肃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7个类型及3个亚型.结果表明,甘肃农业生态气候的资源潜力、匹配状况和利用程度大致呈现南部优于北部、东部优于西部的地域分异特征,在7个类型的农业生态气候资源中,陇南山地型相对较好,而河西走廊型相对较差.基于上述计算结果,进而提出了开发利用甘肃农业生态气候资源的若干建议.

Abstract: Based on the over years data from 86 meteorological stations in Gansu Province,the agro-ecoclimatic resources in this province was systematically analyzed.Resource indices Cr,efficiency indices Ce and utilization coefficient K were calculated by using the dynamic models of agro-ecoclimatic suitability degree.According to the average monthly efficiency indices Ce,the agro-ecoclimatic resources were divided into 7 types and 3 subtypes by fuzzy cluster.The potentiality matching condition and utility degree of agro-ecoclimatic resources showed the evident characteristic of spatial differentiation.Generally,the south was superior to the north,and the east was superior to the west in terms of these parameters,with the type of South Gansu Mountain much better than that of Hexi Corridor.Some suggestions about the exploitation and utilization of the agro-ecoclimatic resources in Gansu province were proposed.

Key words: Agro ecoclimatic resources, Quantitative analysis, Classified evaluation, Gansu province, soil integrated fertility index, soil fertility, cropland requisition-compensation balance, Yangtze River Delta.
