| 摘 要： | 在元江干热河谷海拔1 000 m以下的困难立地上残存的植被较少，且立地条件衰退严重，林相单调、水土保持等生态功能较差，加之受干热河谷特有焚风、酷热、干燥的天气影响，形成了荒凉的植被景观，已成为区域重大生态问题。通过对元江干热河谷困难立地类型上的植被现状进行分析，结合前期众多试验结果和经营措施，提出了适宜于不同困难立地类型的生态修复造林技术措施，以期在生产中得到借鉴和推广。

Vegetation Restoration Techniques for Difficult Sites in Dry and Hot Valley of Yuanjiang River |
| |
| Abstract: | There is relatively little vegetation remaining on the difficult site below an altitude of 1 000 meters in the dry and hot valley of Yuanjiang River, where the site conditions have declined severely, the forest is monotonous, and the ecological functions such as soil and water conservation are poor. In addition, the unique foehn, scorching and dry weather of the dry and hot river valley has formed a desolate vegetation landscape, which has become a major ecological problem in the region. By analyzing the vegetation status of difficult site types in dry and hot valley of Yuanjiang River and combining experimental results and management measures in the early stage, ecological restoration and afforestation techniques suitable for different difficult site types were proposed, with the aim of gaining reference and promotion in production. |
