摘要
针对德钦地区的特殊地貌及生态特征,将区域分为干暖河谷区和亚高山寒温区,分析不同区域植被恢复重建面临的困难和问题,对干暖河谷区提出合理进行树种选择,高质量的整地,使用保水剂,适当深栽,密度适宜,选择最佳种植模式等植被恢复策略;对亚高山寒温区提出推荐适应性较强的造林树种,发展混交林,进行牲畜防护等植被恢复策略。
According to special geological features and ecological characteristics of Deqin, the area is di- vided into dry and warm Valley, cold temperate zone of sub-alpine, the difficulties and problems of dif- ferent regions of vegetation recovery reconstruction have been analyzed in this paper, vegetation restora- tion strategies for dry warm Valley such as reasonable selection of tree species, high-quality soil prepara- tion, use of water retaining agent, appropriate deep planting density, optimal cropping patterns were put forward, meanwhile, vegetation recovery strategies for cold temperature zone of sub-alpine such as recom- mend strong adaptability afforestation tree species, development of mixed forest also been carried out.
