摘　　要： 文章以青岛东部废弃建筑石材矿山治理工程为例,通过对植被系统中的植物生长势、多样性和盖度,以及治理技术对土壤改良等方面的研究,对生态治理的效果进行评估。研究结果表明:坡面植被覆盖达到95%以上,植物根部已经深入营养基质下部岩石裂缝;3个样方的Simpson多样性指数分别为0.76、0.75和0.76,多样性指数较高且相差不大;植被恢复后土壤容重降低了17.61%,最大持水量提升了15.07%,氮、磷、钾等养分含量明显增加。通过生态治理技术建立的植被总盖度、植物密度和生长速度都高于自然植被;植物群落多样性好,整体协调性高;该技术还能有效地改良土壤状况,提高土壤生产力。 This paper took the abandoned quarry mine improvement project in the eastern part of Qingdao City as a case study to conduct the research on the growth potential,diversity and coverage of plant community as well as on the soil improvement technology and also evaluate the effect of ecological improvement. The result showed that more than95% of slope area was covered by vegetation and plant roots went deep into the rock fracture; the Simpson diversity index of the three samples were 0. 76,0. 76 and 0. 75,respectively,which were relatively high and showed no big differences; soil bulk density decreased 17. 61% after vegetation restoration,while the maximum water-holding capacity increased 15. 07%,and nitrogen,phosphorus and potassium nutrient content increased significantly. The overall coverage,density and growth speed of plant community which was built with this improvement technology were higher than those of natural vegetation,and the diversity and overall coordination of this plant community is also high.In addition,this technology could also effectively improve the soil condition and increase the productivity of soil.
