干瘠石质山地环境生态工程构建技术

Eco-environmental Engineering Construction on Hilly Barren and Dry Land

干瘠石质山地是我国分布最广、生态工程建设难度最大的生态环境类型,是近年来生态环境研究和建设的重点。文中分析了我国干瘠石质山地的主要特点和存在的问题,提出了其生态环境恢复和重建的途径,指出了其适宜树种和优化模式,并就其生态工程构建技术进行了重点论述。

Barren and dry land in hilly area is an eco-environmental site type widely distributed and with the highest difficulty in eco-environmental engineering construction,and also the focal point of eco-environmental research and construction in China in recent years.The authors analyzed the main characters of barren and dry lands in China's hilly areas and the problems existed,and indicated the ways of eco-environmental recovery and reconstruction.The authors showed the suitable tree species and optimization patterns,and attention was paid on eco-environmental engineering construction techniques.
