| 摘 要： | 目的]为恶劣条件下植物的选择利用提供依据。方法]分析朝阳山区3种坡地的土壤含水量及8种自然灌木地下与地上的生物量比,评价其生态适应性。结果]土壤含水量阴坡最大,阳坡最小,半阴坡居中,分别为3.47%、1.07%、2.19%。阳坡、阴坡、半阴坡中花木蓝的地下与地上的生物量比均最大,分别为5.441、3.120、3.900。溲疏阳坡的地下与地上生物量比是阴坡的2倍以上。万年蒿阳坡和半阴坡的地下与地上的生物量比明显高于阴坡的,紫丁香和土庄绣线菊却恰好相反。荆条、三裂绣线菊和胡枝子3种坡地的地下与地上的生物量比变化不大。结论]花木蓝的生态适应性最强,溲疏和万年蒿抗旱性较强,适合生长在阳坡,紫丁香和土庄绣线菊适合生长在阴坡,荆条、三裂绣线菊和胡枝子在3种坡地都能良好生长。

| Abstract: | Objective The research aimed to provide basis for the plant selection and utilization under serious conditions.Method The soil water content and the biomass ratios of underground part to overground part of 8 kinds of natural shrubs in 3 kinds of sloping fields in the mountain area of Chaoyang were analyzed and their ecological adaptabilities were evaluated.Result The water content in the soil of shady slope was maximum,and that of sunny slope was minimum and that of semi-shady slope was middle,being 3.47 %,1.07 % and 2.19 % respectively.The biomass ratio of underground part to overground part of Indigofera kirilowii in sunny slope,shady slope and semi-shady slope were all maximum,being 5.441,3.120 and 3.900 resp.The biomass ratio of underground part to overground part of Deutzia scabra in sunny slope was twice more than that in shady slope.The biomass ratio of underground part to overground part of Artemisia sacrorum Ledeb in sunny slope and semi-shady slope were higher than that in shady slope and that of Syringa oblata and Spiraea pubescens were on the contrary.The biomass ratio of underground part to overground part of Vitex negundo var.heterophylla,Spiraea trilobata and Lespedeza formosana had no great change among 3 kinds of sloping fields.Conclusion The ecological adaptability of I.kirilowii is strongest and D.scabra and A.sacrorum had stronger drought resistance and were suitable for growing in the sunny slope,and S.oblata and S.pubescens were suitable for growing in the shady slope,and V.negundo,S.trilobata and L.formosana could all grow well in 3 kinds of sloping fields. |
