【摘要】 京津冀城市群周边生态环境破坏严重,风沙灾害频发。京津冀风沙源治理工程是我国为减轻京津冀及周边地区风沙危害的重大生态修复工程。虽然陆续开展的系列生态工程取得一定效果,但修复过程中暴露的问题也日益突出。系统分析京津冀地区具体生态环境问题和生态修复的制约因素,对该地区的生态重建与服务功能提升具有重要意义。本文从沙地生态环境、防护林状况、植被动态、物种选择和生态功能评价等方面总结京津冀沙地植被生态修复研究进展,分析存在的问题,并据此提出今后修复的改进模式和对策建议,以期为京津冀沙地植被生态修复功能提升提供科学参考。更多还原

【Abstract】 There are serious eco-environmental issues and frequent wind/sand disasters around the Beijing-Tianjin-Hebei Metropolitan Region( Jing-Jin-Ji). Jing-Jin-Ji Dust Storm Sources Control Project is an important ecological construction project in China,with the aim to minimize the sandstorm hazards around the Jing-Jin-Ji. While the project has made some progresses,there are some serious problems during the eco-restoration. The systematical analysis on the constraints to eco-environment and eco-restoration in Jing-Jin-Ji is important to the eco-reconstruction and service function enhancement. Here,we summarized the advances of researches of eco-environment in sandy land,shelterbelt status,vegetation dynamic,tree species selection,and the evaluation of ecological functions in the shelter forests in Jing-Jin-Ji,analyzed the main issues about ecorestoration,and proposed some suggestions to improve the eco-restoration,which could provide effective reference for the vegetation eco-restoration of sandy land in Jing-Jin-Ji.更多还原
