不同轮割制度对典型草原主要种群的影响

选择12个具有代表性的种群,研究不同轮割制度对其地上现存生物量的影响.结果表明,12个种群可以分为3种类型:1)生物量下降型,羊草、米氏冰草、小叶锦鸡儿和黄囊苔草,尤以羊草和小叶锦鸡儿具有代表性.羊草地上生物量的平均值以一年割两次、一年割一次、割一年休一年和割两年休一年依次较对照下降了3.37%、4.9%、45.4%和34.18%;小叶锦鸡儿地上生物量分别较对照下降了81.79%、3.33%、40.29%和2.30%.2)生物量增加型,(艹)/(洽)草、黄蒿、冷蒿和猪毛菜,尤以(艹)/(洽)草和冷蒿具有代表性.(艹)/(洽)草生物量依次较对照增加了94.84%、287.79%、132.8%和211.74%,其中以一年割一次和割一年休一年的增加幅度较大;冷蒿生物量分别较对照增加了193.02%、210.47%、154.5%和10.47%.究其原因,(艹)/(洽)草和冷蒿地上生物量增加是通过种群自身的变化;而黄蒿和猪毛菜则是通过群落密度的下降和适宜的种子萌发条件.3)生物量波动型,大针茅、西伯利亚羽茅、变蒿和麻花头,介于前两种类型之间.

甘肃锦鸡儿（Caragana kansuensis Pojark.）及其易混种的分类学探讨

对甘肃锦鸡儿（Caragana kansuensis Pojark.）及其易混种进行了探讨,认为甘肃锦鸡儿与短脚锦鸡儿（C.brachypoda Pojark.）是两个不同的物种。在陕西北部、山西西北部等地被鉴定为甘肃锦鸡儿的类群,实为错误鉴定,其与甘蒙锦鸡儿（C.opulens Kom.）相近,区别在于前者小叶较狭,两面被毛较密,背面干后常发红色,也与白毛锦鸡儿(C.licentiana Hand.-Mazz.)相近,区别在于前者叶柄较长,小叶较长而狭,荚果近光滑。同意赵一之教授的观点,将其作为C.opulens的一个变异类型处理,发表新变种狭叶甘蒙锦鸡儿（C.opulens Kom. var. angustifolia Y. Z. Zhao ex Zhao. Y. Chang et F. C. Shi）。

Notes on the Genus Elaeocarpus Linn. from China

The Chinese Elaeocarpus Linn. is revised. Here reported are those taxa with different treatment in “Fl. Reip. Pop. Sin. “, Tomus 49 (1), including one new species and one new variety: Elaeocarpus limitaneioides Y. Tang and E. glabripetalus var. grandifructus Y. Tang, Four species and two varieties are reduced: E. boreali-yunnanensis H. T. Chang is reduced to E. lacunosus Wall. ex Kurz; E. floribundioides H. T. Chang to E. austro-yunnanensis Hu; E. fengjieensis P. C. Tuan to E. duclouxii Gagnep .; E. kwangsiensis H .T. Chang to E. glabripetalus var. alatus(Knuth) H. T. Chang; E. glabripetalus var. teres H. T. Chang to E. glabripetalus var. glabripetalus ; E. prunifolioides var. rectinervis H. T. Chang to E. prunifolioides Hu. It is found that three species, E. rugosus Roxb., E. sikkimensis Mast. and E. decandrus Merr., were wrongly determined as E. apiculatus Mast., E. fleuryi Gagnep. and E. chinensis Hook. f., respectively. In the paper also reported are some provincial new records. The infrageneric systems are discussed briefly and the Masters’ system isfollowed with some modifications.
