耐旱、耐贫瘠的乔、灌、草均在石矿迹地的生态恢复中有所应用,但少有经济作物应用到石矿迹地的生态环境治理中.本研究以唐山滦县椅子山石矿迹地为背景,对现场种植的油用牡丹定期检测其生长指标、光合指标和对应区域的土壤特性.研究表明:边坡样地容易水土流失且杂草丛生,不适宜油用牡丹生长.平地种植次年油用牡丹5~7月生长量最大,4~8月增量分别为株高(1.68 cm)、径粗(1.14 mm)、冠幅(51 cm2)、叶片数 (5.58)、叶绿素含量指数(10.51)均明显增大.油用牡丹的种植使土壤pH下降0.145、电导率下降21.45 μS/cm.有机质降低1.2 g/kg,碱解氮降低3.75 mg/kg,速效磷降低了4.16 mg/kg.牡丹根系活动也改善了20~40 cm土层土壤酶活性.对油用牡丹的日光合指标进行监测,得出其净光合速率、气孔导度等光合指标.对油用牡丹特性的研究为其在石矿迹地生态恢复中的应用提供科学指导.“,”Trees, shrubs and herbs with drought and barren tolerance have been applied in the ecological restoration in ore area, but there is little economic crops used in ecological environment in the mining area. In this research, we took the ore area in Yizishan in Luanxian, Tangshan as the background, and detected the growth index, photosynthetic index and soil characteristics in the corresponding area of oil peony regularly. This results showed that slope land was not suitable for oil peony because it was prone to happen soil erosion and overgrown with weeds. The oil peony growth amount was the largest from May to July, and the monthly increment were plant height (1.68 cm), diameter (1.14 mm), crown (51 cm2), leaf number (5.58), chlorophyll content index (10.51) from April to July. The plant of oil peony decreased the soil pH by 0.145 and the conductivity by 21.45 μS/cm. The organic matter decreased by 1.2 g/kg, the alkaline hydrolysis nitrogen decreased by 3.75 mg/kg, and the rapidly available phosphorus decreased by 4.16 mg/kg. Oil peony root activity also improved soil enzyme activity in 20~40 cm soil layer. The photosynthetic indexes, such as net photosynthetic rate and stomatal conductance, were obtained by monitoring the photosynthetic index of oil peony. The study of the characteristics of oil peony provides scientific guidance in the application of ecological restoration in the ore area.
