Abstract: A revision of the Hylodesmum laxum complex is made on the basis of an analysis of morphological variations. Four species, viz., H. leptopus, H. laterale, H. densum, H. laxum, and one subspecies, H. laxum subsp. lateraxum, are recognized. Their diagnostic characters are discussed, and a key to them is provided. Hylodesmum laxum subsp. falfolium (H. Ohashi) H. Ohashi & R. R. Mill is reduced to synonymy of H. laxum subsp. laxum.

Effects of soil temperature and moisture on soil respiration in different forest types in Changbai Mountain

Abstract: The effects of soil temperature (0, 5, 15, 25, 35 degrees C) and water content on soil respiration in three forest types in Changbai Mountain were evaluated in laboratory condition. The results indicated that the soil respiration rate was positively correlated to soil temperature from 0 to 35 degrees C and it increased with soil water content from 0.21 to 0.37 kg.kg-1. The soil respiration rate decreased with soil water content when water content was over the range. The result suggested the interactive effects of temperature and water content on soil respiration. There were significant differences in soil respiration among the various forest types and the highest was in broad leaf Korean pine forest, then in erman's birch forest, and it was the lowest in dark coniferous forest. The optimal condition for soil respiration in broad-leaved Korean pine forest was at 35 degrees C under 0.37 kg.kg-1 water content, and it was at 25 degrees C under 0.21 kg.kg-1 in dark coniferous forest and at 35 degrees C under 0.37 kg.kg-1 water content in erman's birch forest. Because the forests of broad leaf Korean pine, dark coniferous and erman's birch are located at various altitudes, the soil temperatures had 4-5 degrees C variation in different forest types during the same period. The soil respiration rates measured in brown pine mountain soil were lower than those in dark brown forest and they were higher in mountain grass forest soil than those in brown pine mountain soil.

Abstract: 利用武汉WSR-81S数字化雷达回波资料结合卫星云图和地面中尺度观测资料,分析了1987~1994年4~9月份发生在雷达有效探测范围内的所有暴雨过程。揭示了云图上不同种类暴雨云团下的数字化雷达回波模式。根据暴雨雷达回波和地面中尺度系统的统计事实,分析了数字化雷达回波的动态运动与地面中尺度系统活动的关系。
Effect of Various Mulching Durations with Plastic Film on Soil Microbial Quantity and Plant Nutrients of Spring Wheat Field in Semi-arid Loess Plateau of China
覆膜对春小麦农田微生物数量和土壤养分的影响

SONG Qiu-Hua,<br>
生态学报 , 2002,
Abstract: Effect of various mulching durations with plastic film on soil microbial quantity and plant nutrients of the spring wheat field was investigated in semi\|arid Loess Plateau of northwest China for two years. Four treatments were employed: M 0\|no mulching, M 30 \|mulching for 30 days from sowing, M 60 \|mulching for 60 days, and M\|mulching for whole growth period. In 1999, a wet year with rich precipitation, the total soil microbial quantity increased faster and the higher level of soil microbial q...
