本文从旱地农业的基本特点出发,用大量资料对旱地农业进行了区域和类型分类。旱地农业分类指标与气候分类不同,须采用直接的旱地农业因子的基本量,与旱地农业生产的对象的特点要求相一致。因此本文以基本水分量、干旱期、水土影响特征、农林牧需水量、灌溉措施等分类指标,将我国北方旱地农业分为7个区(区域),50个地区(类型),反映出我国北方旱地农业的基本状况和特点,可供布局和发展旱地农业生产参考。
Based on the basic characteristics of dryland agriculture, this paper uses a large amount of data to classify the dryland agriculture by region and type. Different from the climate classification, the index of dryland agricultural classification needs to adopt the basic amount of direct agricultural factors of dryland and is consistent with the characteristics of the target of agricultural production in dryland. Therefore, this paper divides the dryland agriculture in northern China into 7 regions (regions) and 50 regions (types) based on the classification indexes such as basic water content, drought period, water and soil impact characteristics, water demand of agriculture, forestry and animal husbandry, and irrigation measures, The basic conditions and characteristics of dryland agriculture provide a reference for the layout and development of dryland agricultural production.
