北疆引水干渠边坡生态恢复效果的调查与评价--以新疆克拉玛依市西干渠工程黄旗坝段为例
Effect of Slope Ecological Protection Measures in Northern Xinjiang Uygur Autonomous Region-Taking Canal Program in Western Part of Karamay in Huangqiba Section in Xijiang Region as a Case Study
摘要
Abstract
Objective] T he objective of this study is to analyze the effect of slope ecological protection meas‐ures in western part of Huangqiba section in northern of Xinjiang Uygur Autonomous Region ,in order to provide the scientific basis for regulating vegetation succession rate and expected vegetation restoration effect .[Methods] We investigated soil and vegetation conditions in the canal slopes caused by excavation and natural habitat at the top of channel .[Results] (1) After ecological restoration ,the plant density ,coverage , evenness index(Pielou) ,diversity index(Shannon‐Wiener) and richness index(Margalef) in the sunny and shady slope has been improved ,and the improvement in shady slope was higher than in the sunny slope ,but still lower than the natural habitats .(2) Soil nitrogen ,phosphorus ,potassium nutrient characteristics in both shady slope and sunny slope were increased ,however ,they were still lower than the level of natural habitats ,which showed as :the natural habitat > shady slope > sunny slope . (3) After the ecological restoration ,the plant community index of the shady and sunny slope was still low ,and the community suc‐cession was still in the stage of shrub and grass plant community .[Conclusion] The slope ecological restora‐tion technology can improve the soil fertility status and promote the grow th of vegetation on the side slope . Due to the special environmental conditions of the west main canal area ,short‐term ecological restoration measures is not enough and long‐term restoration is needed .In addition ,native plants should be selected in the slope ecological restoration plant in the northern area of Xinjiang region .关键词
