摘要：

针对巢湖直立堤岸生态系统受损的现状，研发了适合于巢湖迎风面的直立堤岸基底改善与生态修复技术。考虑到直立堤岸迎风面风浪较大且淘蚀严重的特点，首先对传统的生态混凝土配方进行改良，从而较大程度地提高了生态混凝土的物化性能，使其具备高透水性、高稳固性、植生性等诸多优点。同时，以巢湖湖滨带现场调查与野外模拟实验结果为依据，确定巢湖湖滨带最适的基底类型为灰壤（植入深度10 cm），并适当添加铁盐和铝盐；确定最适的植被类型为飞蓬草。在此基础上，确定生态混凝土最适配比为江砂〖DK〗∶碎石〖DK〗∶水泥=10〖DK〗∶3〖DK〗∶2，进而集成研发了生态混凝土原位土壤植被混合护坡技术。该技术应用到迎风面的直立堤岸后，植被覆盖率超过70%，土壤中有效磷削减67%以上

Abstract:

In the light of impaired ecosystem of rigid embankment in Lake Chaohu,soil amendment and ecological rehabilitation technology of windward rigid embankment was studied.Based on the characteristics of the strong winds and serious erosion in rigid embankment,the traditional ecological concrete formula was optimized,thus greatly improving physicochemical properties of the ecological concrete,which had high permeability,high stability,plant growing and many other advantages.At the same time,according to field investigation of lakeshore in Lake Chaohu and field simulation experiment,the optimal soil and plant types in lakeshore were screened.On this basis,in view of the relationship between ecological concrete,soil and plant,ecological concretesoilplant slope technology was integrated.This technology could stabilize embankment,restore ecosystem and effectively reduce nonpoint nutrients
