扦插-抛石联合技术的构建与应用

为探讨扦插-抛石联合措施在河岸带生态修复中的适用性,简述了扦插-抛石联合措施的施工方法,并对其岸坡防护、水质净化、栖息环境改善和景观等功能进行分析;以长园河段扦插-抛石联合护岸为例,对扦插植物生长情况、根系的生物量和枝条的抗弯性进行了调查分析。结果表明:金丝垂柳生长情况良好,完工2个月后,新枝高度和基径分别平均增长到28.7 cm和0.3 cm;完工5个月后,新枝高度和基径分别平均增长到135.7 cm和1.0 cm;金丝垂柳根系扎根深、生长快,对深层土壤的加固作用良好。其新生枝茎有良好的抗弯性,柔韧弯曲的枝条覆盖坡面可起到保护坡面土壤被水流冲蚀的作用。

Construction and application of cutting and riprap joint planting technology

In order to discuss the suitability of cutting and riprap joint planting methods used in riparian restoration,the construction method of joint planting is introduced and the functions of the method,including strengthening riprap stability,purifying water quality,improving habitat and beautifying the landscape,are discussed.Using the joint planting revetment along the Yanqi River as an example,the performance of cut plants,root biomass and shoot bends are investigated.The results show that the golden silk willow grows well.The length and diameter of new shoots increased by 28.7 cm and 0.3 cm after two months,and increased to 135.65 cm and 1.0 cm after five months.The golden silk willow has a deepened root system and has a good reinforcing function in the deep soil. The golden silk willow has satisfactory bending and restorable properties.Flexible and bending branches cover the slope and protect it from water erosion.
