摘　　要：以朝阳市矿山破损山体为研究对象,通过采用景观重建恢复模式,对其治理效果进行了研究,结果表明:破损山体所有树种成活后长势良好,试验地1树种保存率为53%~95%,其中以紫穗槐(Amorpha fruticosa)保存率最高,桧柏(Sabina chinensis)保存率最低;试验地2保存率为63%~93%,其中以紫穗槐保存率最高,地锦(Euphorbia humifusa)保存率最低。树木的生长为野生草本提供了良好的生长环境,蒿类、禾本科草类均生长良好,繁衍迅速,试验地1和试验地2治理后树种多样性和草本盖度显著增加,分别达到0.67~2.04和40%~95%。Taking the damaged mountain masses of Chaoyang City as the research object,the governance effect was studied by adopting the landscape reconstruction and restoration model.Result shows that:All tree species grew well after survival.The preservation rate of tree species in test site 1 is 53%-95%.Among them,the preservation rate of Amorpha fruticosa is the highest,and the preservation rate of Sabina chinensis is the lowest.The preservation rate of test site 2 is 63%-93%.The preservation rate of Amorpha fruticosa is the highest and that of Euphorbia humifusa is the lowest.The growth of tree species provides a good growth environment for wild herbs.Artemisia,Lespedeza bicolor,and gramineous grasses all grow well and multiply rapidly.The tree species diversity and herb coverage increase significantly after treatment in experimental site 1 and experimental site 2,respectively reach 0.67-2.04 and 40%-95%.
