摘要
用CS高次团粒混合纤维法植被恢复技术对金竹山煤矸石矿区进行植被恢复,25个月后对喷播刺槐等10种植物的土壤中矿质营养元素含量、植被生长情况及景观进行了调查.结果表明:土壤中有机质、钙、氮、磷和钾含量均明显升高,其中有机质含量是对照的11倍多,但是镁元素的含量下降;单位面积的灌木数量较少,只有28株/m2,而单个个体的直径较粗,最粗的刺槐直径达3.06 cm,高达4 m;土壤表面积累的枯枝落叶厚度达2.96 cm;景观发生了明显的变化,原本裸露的煤矸石经CS技术处理后形成以刺槐为主体的植物群落,景色优美.
By using CS plant restoration technology, a vegetation restoration was carried out on Jinzhushan Coal-waste Pile District, 25 months after, the contents of its soil nutrition elements, the growth of its plants, and its landscape were all investigated. The results show that the content of organic matter increases by 11 times; that the contents of Calcium, Nitrongen, Phosphor and Kalium also increase obviously except a decrease in that of Magnesium! that although the number of shrubs per square meter is not very big, being only 28, their diameter increases, the widest being 3.6 cm, and their height grows to 4 m, the thickness of litter being 296 cm; and that the once-bald, exposed coal-waste pile district is now coved with green plants, forming a plant community typical of silver chain and assuming a beautiful landscape
