摘要:

该文运用综合因子法和主导指标法相结合的原则对甘肃省日光温室蔬菜生产进行了气候区划。该 区划利用甘肃省1971～2000年的气候整编资料，以1月平均气温0℃等温线为一级区划指标，将甘肃省分 为北部Ⅰ区、南部Ⅱ区两个一级区，并在北部Ⅰ区做二级分区和三级分区。二级区划采用综合因子原则， 利用系统聚类分析法将北部区划分为4个二级区。三级区划采用主导指标原则，将北部Ⅰ区划分为7个三 级区。通过分区评述各级区的气候特点，指出在该区内发展温室生产的气候资源优势和不利气象条件，提 出各区的温室发展方向。

Abstract:

In order to differentiate the influences of climatic conditions on solar greenhouse production， understand the basic requirements of solar greenhouse production in different areas， the climate regionalization for solar green- house vegetable production in Gansu province was made by adopting the combined methods of integrated and domi- nant factors. In compliance with the principles of climatic regionalization， first of all the Northern and Southern re- gions were divided according to the mean temperature contour of 0℃ in January in Gansu province based on the cli- matic data from 1971 to 2000， then the regions and sub-regions were divided in the Northern region. The North- ern region was divided into four regions by the methods of cluster analysis， seven sub-regions by trend of index isoclines. Through the analysis of climatic characteristics in different regions， climatic resources advantages， disad- vantages and goal of greenhouse development were also put forward.
