我国西北地区节能型日光温室蔬菜生产气候区划

The Climatic Regionalization for Vegetable Production in Energy-saving Solar Greenhouse in Northwest of China

近年来,我国西北地区节能型日光温室蔬菜生产发展迅速,但与东部地区相比,水平较低,规模小,技术落后,产前、产中、产后环节不配套,品质及经济效益低。西北地区大部分属于大陆性干旱、半干旱气候,气候差异较大,有丰富的光热资源。为此,应用主成分分析和系统聚类方法对我国西北地区节能型日光温室蔬菜生产进行分区,分为4个气候区。结果表明:分区结果合理,能客观反映我国节能型日光温室蔬菜生产的区域特点。

In recent years, the vegetable production in energy-saving solar greenhouse in Northwest of China has developed rapidly. However, compared with East, the Northwest has the disadvantages of lower level, small scale, poor quality, and low economic benefit. The most regions in Northwest belong to continental arid and semiarid climate. The climate diversity in Northwest is greater. But there are abundant resources of light and heat. Hence, through applying the method of principal component analysis and system cluster, the Northwest, where produces the vegetable in energy-saving solar greenhouse, is divided four climatic regions. The results indicate： this zoning result is reasonable to reflect the regional characteristics of the vegetable production in energy-saving solar greenhouse in China.
