| 摘 要： | 按非地带性规律分布的干热河谷景观生态区是中国南方局部区域荒漠化过程的前奏，文中试图以云南干热河谷区为例，对其总体分布状况及特征，土地利用中的气候、生物等限制性因子进行评价分析，提出云南干热河谷坡地利用评价的指标体系，并对后备土地资源进行了总体评价，在多年野外定点试验工作的基础上，归纳总结出具备一定实用推广价值的干热河谷坡地改良利用途径和技术方法，最终得出云南干热退化生境区一系列先锋树种引种选择的指导性意见。

| Abstract: | The eco landscape regions in hot arid valleys, which are distributed in southern China according to azonality law, are the prelude of desertification. The hot arid valleys in Yunnan are taken as examples. The general distribution patterns and features of the valleys and the natural restrictive factors of land use are analysed, and a set of indexes for evaluation of the slope lands in hot arid valleys of Yunnan are put forward. After several years, field experiment in the fixed sites, the technique to improve and use the slope lands in the hot arid valleys is developed, and a series of varieties of trees are suggested to be the pioneer trees for improving the hot arid slope lands. |
