In this paper , with the helps of the ordinary ecological site - study techniques , electrophoresis and the multivariate analyses , from both the levels of morphological and allozymic variation , we studied the differentiation patterns of 29 morphological characters and 6 allozymes of 97 individuals from 7 populations of euonymus chloranthoides yang , an endangered plant species which is endemic to mt . jinyun of chongqing . we also studied the relationship between such differentiation and its environment factors 本文以处于濒危状态的缙云卫矛为研究对象，在测定了各种群的生存环境因子基础上，从形态和等位酶两个层次采用多种数量分析方法对缙云卫矛7个种群97个个体的29项形态指标及6种等位酶反映出的生态遗传分化及其与环境的关系进行了研究。
Big drops were dripping from a broken waterspout , and a ray of gaslight slipped from mme bron s window and cast a yellow glare over a patch of moss - clad pavement , over the base of a wall which had been rotted by water from a sink , over a whole cornerful of nameless filth amid which old pails and broken crocks lay in fine confusion round a spindling tree growing mildewed in its pot 大滴大滴的水珠从水管的裂缝中滴下来。一道煤气灯的灯光从布太太的窗子里射进来，把一段长了苔藓的路面一段被厨房的排水沟的污水侵蚀了的墙根及整个堆满了垃圾的角落映成了黄色，垃圾中有旧水桶和破坛碎罐，一口破锅内竟然长出了一棵瘦小的卫矛。
The death rate of individuals in dongwenquan population shows another pattern with slowly raise along with the age . 3 with the use of the dispersal index ( di ) clump intensity ( ci ' s ) mean crowding ( m * ) patchiness index ( pai ) . . green ' s index ( gi ) and intensity index as parameters , we further studied the spatial distribution patterns of the three populations ， chtoran ， hoidesyaog )种群结构与动态研究3 、用leshe矩阵模型定量预测三个种群未来20a的数量与年龄结构变化的结果显示，北温泉绪云卫矛种群数量在未来4a内会有一定程度的减少，以后的种群数量逐渐增加，呈不断扩大的趋势，而这其中幼龄个体所占的比例越来越大，老龄个体的比例越来越小。
