摘要
干热河谷区环境脆弱,生态修复困难。在我国,干热河谷主要分布在金沙江、红河、澜沧江和怒江等流域。结合国内外相关研究,梳理我国干热河谷区的气候特征、土壤特征、植被情况及造林技术,分析干热河谷区生态修复的优缺点,提出对策和建议。结果表明,我国干热河谷区生态修复树种配置较单一,造林成活率较低,综合效益较差;需优化造林树种及配置,创新造林方法及种植设备,保护原生生态环境,建立长期生态环境监测及效益评价体系。
Environment of dry-hot river valleys is fragile and ecological restoration is difficult.In China,dryhot river valleys are mainly distributed in Jinsha River,Red River,Lancang River,and Nujiang.Combining with domestic and foreign related researches,climatic characteristics,soil characteristics,vegetation and afforestation techniques of dry-hot river valleys in China were hackled,merits and faults of ecological restoration in dry-hot river valleys were analyzed,and countermeasures and suggestions were put forward.Results showed that there were single tree species configuration,low survival rate of afforestation and poor overall benefit in ecological restoration in dry-hot river valleys.It was necessary to optimize afforestation tree species and configuration,innovate afforestation methods and planting equipment,protect original ecological environment,and establish long-term ecological environment monitoring and benefit evaluation system.
