摘要
针对京郊荒滩实际，设计出生态恢复模式，并在龙庆峡荒滩进行了试验示范研究。结果表明：刺槐、中间锦鸡儿、紫花苜蓿等14种乔灌草在试验示范区被成功引种；乔灌草复合结构能更有效防风固沙和改善林下小气候；生态垫覆盖树穴，0～20cm土壤含水量比对照平均提高26．5％～47．6％；环保型容器苗造林，苗木高径比比大田植苗造林提高1．1％～9．5％；“根宝”浸根造林，苗木当年高增长比对照平均增加4．6％～79．8％，成活率提高0．7％～16．5％。
According to the status quo of the abandoned beach in Beijing outskirt, the model of ecological restoration is devised, tested and demonstrated in Longqingxia abandoned beach. The result indicates that Robinia pseudoacacia, Caragana sinica, Medicago Satival, etc. 14 vegetable species are successfully introduced; multiple arrangement of arbor, shrub and grass can effectively preventing wind, fixing sandy land and meliorating underlayer microclimate of woods; covering the floor with the eco-mat, the soil water content of 0-20 cm averagely increased 26.5 %-47.60% than CK; using degradable container breed container-seedlings and afforestation, ratio of height to diameter averagely increased 1.1%-9.5% than CK; dipping seedling root in ＂genbao＂ diluents before afforestation, quantity of added seedling height increased 4.6%-79.8% and the survival rate increased 0.7%- 16.5 % than CK in the first year of afforestation.
