我国高原干旱气候区作物种植区划综合指标体系研究

Study on Integrative Index System of Crop Ecological Suitable Planting Division in Arid Climate Condition of Altiplano Region

在高原地区建立以气象、地理位置、经济效益等不同指标类型和权重系数的干旱气候作物生态适生种植区划综合指标体系,并以定量标准进行5级作物生态适生种植区划等级的划分。该综合指标体系具有实践性、经验性、客观性和应用性的特点。

Based on different index styles and its occupied weighing coefficient such as meteorology, geography position, economicbenefit and so on, a integrative index system of crop ecological suitable planting division under arid climate condition of Altiplanoregion was established. At the same time, the grade of crop ecological suitable planting division was plotted out five ranks by quantitative criterion. As a whole, the integrative index system has many characteristics such as practical, experiential, external and applied.
