整理四川蜘蛛标本时,发现我国皿蛛一新记录种,其触肢器形态结构与克什米尔盖蛛相同,外雌器与缅甸盖蛛相同.克什米尔盖蛛由Di Caporiacco在1935年依据1头残缺雄蛛标本订立,缅甸盖蛛是Thorell在1887年依据1头雌蛛标本订立.根据所采得成对标本的外生殖器的形态结构,笔者认为克什米尔盖蛛是缅甸盖蛛的雄蛛,前者是后者的新异名.  相似文献

通过比较狼蛛科豹蛛属的星豹蛛和拟环纹豹蛛雄蛛分别在两种雌蛛释放的拖丝上的求偶行为差异,验证两种豹蛛雌蛛拖丝上化学信息物质在物种识别中的作用.研究发现,两种雄性豹蛛在同种雌蛛拖丝上的求偶潜伏时间都显著短于在异种雌蛛拖丝上的求偶潜伏时间,两种雄性豹蛛在同种雌蛛拖丝上的求偶强度都显著强于异种雌蛛拖丝上的求偶强度.可见雄性豹蛛能通过雌蛛拖丝上的化学信息物质进行种内识别.  相似文献

日本近代史上的"中国通",往往被当作日本浪人来看待。可以说,在中国人的心目中,日本的中国通就是日本帝国主义的帮凶、走狗和马前卒。然而,通过考辨其历史成因得知,真正的中国通有别于日本浪人,他们是一些精通汉文化的、高层次的知识分子群体。应该说,只有具备汉学或中国学素养的文人学者,才有资格被授以这种称呼。  相似文献

采用全球海气耦合模式ECHO-G的1000个模式年的长积分气候模拟方法分析了中国中世纪暖期温度的存在性与时空变化特征.结果表明:中国的中世纪暖期出现在公元1000—1250年间,但它不是一个持续稳定的暖期,而是存在峰谷起伏变化,其中最暖的30年(中世纪暖期鼎盛期)出现在1131—1160年.中世纪暖期中国的年平均和冬、夏季平均温度距平变幅西部最大,东部最小.其鼎盛期中国的温度距平相对于千年温度都是正值,中国东部的增温幅度由南向北逐渐加大,变幅为0.4℃—0.8℃,而中国西部的增温呈Ω型分布,且随着海拔高度的增加,增温幅度逐渐加大,最大增温达2.0℃—2.2℃.  相似文献

Estimation of emissions from field burning of crop straw in China   总被引:10,自引:0,他引:10  
Emissions resulting from crop straw field burning in China, which have caused serious environmental problems in China, are estimated in this paper. From the county-level data of crop production in 2000-2003 from the government statistics, taking into account the ratio of residue and grain, the total amount of crop straw production is estimated to be about 600 Tg per year, 76% of which are rice, wheat and corn straw. With reference to the data of living standards, the percentage of crop straw burnt in fields for counties are obtained and consequently the total amount of burnt straws is approximately 140 Tg/year. With the emission factors from literature and experiments, appropriate emission factors have been obtained. The total amounts of PM, SO2, NOx3, NH3, CH4, BC, OC, VOC, CO, CO2 emissions from field burning of crop straw in China are estimated. All emissions are presented at county level. Some pollutants, such as BC, VOC, OC, CO and CO2, are contributing a major portion to the total emissions of China. This paper uses a map with resolution of 0.2°×0.2°to present the PM emissions distribution from crop straw burnt in 2003. The results show a significant regional unevenness of emissions, with larger amounts of pollutions coming from the provinces in eastern and northeast China. The regions with higher emissions per unit area are located as a belt stretching from northeast China to eastern China.  相似文献

The chondrite-normalized REE distribution patterns in recent sediments from the northern South China Sea and surrounding areas are similar, with the HREE values being almost equal to or slightly higher, and the LaN/LuN ratio being lower, than PAAS standards. However, samples from the Xijiang River, a major branch of the Pearl River system, show opposite trends, i.e., with slightly lower HREE values and higher LaN/LuN ratio than PAAS. The distribution of Nd isotopes in sediments from the northern South China Sea was controlled by the Pearl River and the inshore area of South China, respectively. The volume of εNd(0) from inshore areas of southern China is apparently higher than that from the Pearl River, and εNd(0) values in offshore sediments and Taiwan Island are between these values. The results clearly show that εNd(0) volume in the northeastern South China Sea is higher than in the southwest part of the northern South China Sea, indicating different source rock types. The main source rock of the Pearl River sediment is carbonate types and affects sediment deposition in the southwest of the northern South China Sea, while the source rock in the inshore area of southern China, mainly Mesozoic and Cenozoic granites, contributes to sediments in the northeastern area of the northern South China Sea. Due to different source rock types, the HREE values and the volume of εNd(0) in recent sediments supplied by the inshore area of southern China are higher than those from the Pearl River. Over 80% of the rapidly accumulated sediments on the northern slope of the South China Sea in the southeast of Dongsha Islands area were derived from Taiwan Island and from inshore areas of South China, with only less than 20% from the Pearl River.
