甘肃省农业生态气候资源潜力比较与利用探讨

依据８６个气象台站１９５０－１９９０年多年平均的气候资料，采用农业生态气候模型，对甘肃省农业生态气候的资源潜力，匹配状况和利用程度进行了量化分析，得出农业生态气候资源南高北低、东高西低的地域分异特征，其结果与用迈阿密模型和桑斯模型估算的甘肃省自然植 生产潜力、瓦赫宁根据型估算的甘肃省农田主要农作物的最大产量以及统计部门公布的甘肃省农田农作物的现实产量的分布趋势大致相符。基于上述分析，认为农业生态气

Comparative analysis and exploitation discussion of agro-ecoclimatic resources in Gansu Province

Using average data of many years from 86 meteorological stations in Gansu Province,based on three dynamic models of agro ecoclimatic suitability degree,resource indices C r,efficiency indices C e and utility coefficient K were calculated and the characteristics of spatial differentiation on agro ecoclimatic resources about high in south and east and low in north and west were concluded.The result is the same with the changing trend of the primary productivity of natural vegetation by Miami model and Thornthwaite memorial model,the maximum yield of main crops in various regions by Wageningen measurement and the realistic yield of main crops in various regions by statistics yearbook.On the basis of the above analysis,it is considered that the models of agro ecoclimatic suitability degree is the scientific foundation to improving of potential productivity of agriculture in Gansu Province.
