摘要
对浙江省湖州市不同森林植被枯落物的营养元素进行了分析。结果表明 :不同植被枯落物营养元素含量有较大差别。杉木林枯落物含有较高的钙和镁 ,但铁和铜的含量很低 ;毛竹林枯落物含有较高的钾、镁和铁 ;总体上看 ,灌木林、阔叶林和针阔混交林枯落物各种营养元素含量均较高。 1 0种营养元素在枯落物中的总贮量呈现出针阔混交林 >阔叶林 >马尾松林 >杉木林 >毛竹林 >灌木林的排序 ,其贮量分别为 1 2 3 78,97 0 2 ,74 71 ,73 62 ,66 66和 62 85kg·hm-2 。表 2参
Chemical elements of litter under various types of forests in Huzhou,Zhejiang were analyzed.It was shown that the amount of elements had evident discrepancy among five kinds of litter.Litter Cunninghamia lanceolata contained relative higher content of Ca and Mg,but lower Fe and Cu.Litter of Phyllostaachy pubescens had more K,Mg and Fe.It was the general case that litter of bush,broad leaved forest and mixed forest of needle and broad leaved trees were richer of variety nutrient elements.Total storage of 10 elements appeared the following order:mixture>broad leaved> Pinus massoniana > Phyllostaachy pubescens >bush with the amount of 123 78,97 02,74 71,73 62,66 66 and 62 85 kg·hm -2 respectively.
