| 摘 要： | 通过野外调查和GIS地形分析，获取元阳梯田的基本分布特征，旨在为进一步明晰元阳梯田的分布和形成格局，为现代梯田的管理和保护提供理论参考和指导。结果表明:元阳梯田现有面积26 363.02 hm2，集中在1 hm2左右，尤以小于1 hm2的分布最为常见，梯田常见分布在海拔1 000～1 300 m，坡度为15°～25°的西北、东北和北向山地。哀牢山特有的植被垂直分布特征和当地少数民族生存地分布特征，造就了元阳梯田的空间分布特征；低纬度干热河谷区常年出现的高温和高山“阴湿高寒区”受到冷气团的冷却和压迫，进而保障了元阳梯田水源充足，两者的结合造就了哈尼梯田特有的农耕文化景观。

| Abstract: | The basic spatial distribution and formation pattern of Yuanyang rice terrace were obtained by the field survey and GIS terrain analysis, which is important to reconstruction of degraded ecosystems, sustainable ecosystem benefit development, as well as the establishment of theoretical reference and guidance for modern terrace management and protection. The research results show that the total area of rice terrace is 2.64×104 hm2, area mostly distributed in 0~1 ha, especially in less than 1 ha, and the centralized distribution of rice terrace from 1 000 to 1 300 m, the slope of 15°~25°, with the northwest, northeast and north exposure field. Special vegetation vertical distribution characteristics on Ailao Mountain and the distribution characteristics of local minority habitats are the mainly reason for the basic spatial distribution. High temperature occurs in dry-hot valley of low latitude and cooling current on high altitude which ensures the abundant water supply of rice terrace, and created the terraced landscape of farming culture for thousands of years. |
