摘要
研究了扫帚艾群落初级生产。结果表明，该群落初级生产量季节动态明显，地上初级生产量５，６，７，８，９月份分别为１２．０４，２３．４０，４３．８２，７１．１５，１５４．６６ｇ／ｍ２；地下初级生产量５，６，８，９月份分别是５０．２５，６０．４０，６６．６７，１４９．５９ｇ／ｍ２。
The primary production of Artemisia scoparia community is studied, the tesult indicates that the seasonal dynamics of primary production was evident, the aboveground primary production in May, June, July, August, September are 12.04, 23.4, 43.82, 71.15, 154.66 g/m 2 respectively; the underground primary production in May, June, August, September are 50.25, 60.40, 66.67, 149.59 g/m 2 respectively.
