摘  要:
文章以安定区不同树种退耕还林地为研究对象,在植被调查的基础上,对不同树种退耕还林地的地上、地下生物量、林下草本层生物量以及枯枝落叶层生物量进行测定分析。结果表明:由于受树种生物学特性的影响,不同树种退耕还林地生物量的积累具有明显的差异,即山桃>刺槐>侧柏>柠条>山杏,除山桃和柠条外,其他树种的地上部分生物量均大于地下部分。可见,山桃和刺槐作为安定区退耕还林的主要物种优势明显,同时,发达的根系,对改善土壤环境,减少水土流失具有重要作用,可以作为本地的经济林来发展。

摘  要:
Having studied on Returning farmlands to forest with various tree species and measured the biomass of overground underground, and herb layer biomass and litter layer with in An Ding area, the result shows: for various biological characteristics of vegetation themselves, is obviously different tree species,like P.davidiana> locust> orientapis> peashrub> apricot, is of difference of biomass accumulation,and excepting P.davidiana and peashrub, the overground biomass of other species is larger than underground. So,there has obvious advantages to take P.davidiana and locust as the main species of returning farmland to forest, and well-developed root system is important on improving the environment of soil and reducing soil erosion, besides they can be developed as local economic forest.
