低山丘陵区开发建设项目水土保持与生态建设

边坡植被恢复是解决高速公路建设所造成的环境破坏问题的重要手段之一,已受到人们的普遍重视.但是,对坡面植被恢复质量的评价尚没有统一、公认的指标体系.基于恢复生态学和美学的理念,在分析坡面植被功能的基础上,参考道路工程、植物生态学、恢复生态学、草地生态学、水土保持学、景观学等理论.提出了绿期、盖度、多度、截流量、综合抗性、根系稳定效果、景观优美度、管理水平8个重要评价指标,并给出了各指标的量化计算办法.利用AHP评判矩阵计算了各评价指标的权重.根据坡面植被群落的演替规律,提出了建议的评价时间,得出了坡面植被恢复质量的评价值,确定了质量等级.结合2008年奥运公路--济南至青岛高速公路南线工程,进行了实例分析.

Soil and Water Conservation and Ecological Reconstruction of Development and Construction Project in Low Mountain and Hill Region

By taking the Qianbei 2. 0 ×10⁵t/a bamboopulp paper production projectin Chishui City,Guizhou Province,China for an example,soil and water conservation and ecological reconstruction of the developmentand construction projectin the low mountain and hill region are discussed. Based on the analyses of engineer ing scale,construction methods,and circulation forms,as well as the currentsituation and features of soil and water loss,comprehensive controlling countermeasures of engineering and vegetation and other potential protection measures are presented in accordance with five controlling principles. After the controlling meas ures are finished,soil and water loss in the projectsite can be effectively controlled,destroyed ecological environmentcan be recovered and improved,and the safety of engineering reconstruction can be ensured. Therefore,coordinative and sustainable developmentof society,economy,and environmentcan be achieved.
