| 摘 要： | 对陕北森林草原地带由于水蚀，风蚀和过度放徼形成的一类次生草原群落－地椒群落６、７月分的地上和地下生物量及其空间变化进行了研究。结果表明，地椒群落６、７月份地上生物量分别为８７．７ｇ／ｍ＾２和７７．１３ｇ／ｍ＾２地下生物量是２３６．４５ｇ／ｍ＾２和１６０ｇ／ｍ＾２。７月地上和地下生物量都偏低。这与地椒生长发育节律的物质分配有关。

| Abstract: | The paper studied the aboveground and underground biomasses and spacial change ofThymus mongolicus community in June and July.The result showed that the aboveground biomass was 87. 7g/m2 in June and77. 1 3g/m2 in July; The underground biomass was 236. 45g/m2 in June and 160g/m2 in July. The twobiomasses in July were lower than in June,this related to the material distribution of growth and developme-nt rhythm of Thymus mongolicus. |
