由于长期开采花岗岩建筑石材,“2014年青岛世园会”百果山园区的花岗岩丘陵上遗留有6处开采石材形成的岩石崖壁。在园区建设过程中,将这6处岩石崖壁分为坡度70°以下的岩石崖壁和坡度70°以上的岩石崖壁2类,并遵循可行性原则、地域性原则和美学原则,分别提出了2类岩石崖壁景观的生态恢复与重建措施。其中,坡度70°以下的岩石崖壁可采取底层采石坑回填、“钻孔植绿”与“筑巢复绿”等措施进行生态恢复与重建;坡度70°以上的岩石崖壁可采取布鲁特罩面网垂直绿化技术、人工植生槽与顶部筑营养槽相结合,建造人工流水景观,建造人造雾喷景观,融入雕塑艺术等措施进行生态恢复与重建。 相似文献

中国典型储粮生态区低温储粮的优化集成方案 总被引:4,自引:1,他引:4
根据储粮生态环境,将我国分为三个典型的低温储粮生态区域,即低温区、中温区和高温区。提出了三个储粮生态区域低温储粮对仓房隔热条件和气密条件的要求及不同地区低温储粮的优化集成方案。低温区最佳的低温储粮模式是:冬季通风降温 夏季隔热 适当控温;中温区最佳的低温储粮模式是:冬季机械通风降温 夏季严格隔热 必要的控温;高温区最佳的低温储粮模式为:冬季机械通风降温或谷物冷却机降温 夏季严格隔热 谷物冷却机降温。同时给出了三个储粮生态区域低温储粮优化方案的工艺流程图。 相似文献
