我国山地农业气候资源优势及其合理利用

据我国农业气候调查和考察资料,分析不同山区光热水农业气候变量在垂直和水平方向的变化规律,提出山地农业气候资源具有立体性、多层性、多样性和多宜性的特征,建立山区农业气候资源垂直分层模式;据人力、物力、耕地、物价等社会条件和经济效益等因素约束,应用系统决策寻找山区不同层次最佳的作物布局和农作制,探讨农业合理布局的生态气候效益及开发山区资源优势的途径。

THE SUPERIORITY OF AGROCLIMATIC RESOURCES IN THE MOUNTAINOUS REGION IN CHINA AND ITS RATIONAL UTILIZATION

Based on agroclimatic survey and observations carried out in the mountainous region in China, the vertical and horizontal distribution of the agroclimatic elements (sunshine, temperature and precipitation)were analysed. It is found that the agroclimatic resources of the mountianous region have the features of the cubical agriculture .diversity,many layers and suitability. The models of vertical divided layers of agroclimatic resources were established in this region. In the light of labours,material resources,prices,cultivated land and economec effect etc; the modes of applying system decisions seek the optimum crop distribution and cropping systems of the different layers in the mountainous region. The ecoclimate effects of the rational distribution and the development ways of the agroclimatic resources are discussed.
