摘要:
通过对三峡水库典型的6处消落带地区145～175 m范围内植物群落的调查，研究三峡库区不同高程植物群落的分布情况，消落带优势物种狗牙根香附子等草本植物生长状况的影响因素。结果表明：高程差异、地理位置、坡度急缓是影响植被群落种类分布及植物生长高度主要因素。随着高程的增加，植被群落种类增加，植被的生长高度增加；地理位置环境条件差别较大，导致地区土壤水分、肥力差异明显，植被群落种类及植被生长高度不同；坡度决定淤积层厚度，坡度越陡，淤积层越薄，植被生长高度越高。并根据调研结果分析影响植被群落种类分布及生长高度的影响因素，探究库区适宜生长植被种类，为三峡库区消落带生态修复提供建议和参考。
Abstract:
Based on an investigation of six plant communities in the typical fauna zone of the Three Gorges Reservoir from 145m to 175m, the distribution of plant communities at different elevations and the major factors affecting the distribution of herbaceous plants such as the dominant species of the fascia in the Three Gorges reservoir area were explored. The results show that the elevation difference, geographical location and steep slope are the main factors affecting the distribution of vegetation community species and plant growth height. With the increase of elevation, the variety and height of vegetation communities increased. The geographical conditions of the geographical environment were different, resulting in obvious differences in soil moisture and fertility, vegetation species and growth height. The slope determines the thickness of the silt and slope. The steeper the sedimentation layer, the higher the height of vegetation growth. On the basis of the survey results, the influencing factors affecting the species distribution and growth height of vegetation communities are analyzed, and the suitable vegetation types in the reservoir area are explored to provide suggestions and references for the ecological restoration of the Three Gorges reservoir area.
