缙云卫矛 meaning in English
euonymus chloranthoides
Examples
- The dominant factors affecting the growth of the endangered plant e . chloranthoides yang come from the soil
可见，影响缙云卫矛生长的主要的主导因子来自于土壤条件。 - The result shows as the followings : 1 . the age structure of the three populations is basically a bell - shaped one . the seedlings in each population are relatively rich
本研究的主要结果如下： 1 、缙云卫矛三个种群的年龄结构基本上呈钟型，幼苗数量均比较丰富，属于稳定型的种群。 - Euonymus chloranthoides yang is an endangered plant species which is endemic to jinyun mountain and dongwenquan of chongqing with the most favorable habitat in the forest of sinocalamus affinis ( rendie ) mclure . we made field investigations on three natural populations available presently in the whole distribution areas of e . chloranthoides
缙云卫矛( euonymuschloranthoidesyang )是重庆特有种，目前处于濒危状态，主要分布于重庆北碚区缙云山、鸡公山及渝北区的东温泉内，生境多为慈竹林。 - 2 , the survival curves of populations of e . chloranthoides in jigong mountain and dongwenquan are diagonal , which indicates that the individuals of each age grade within the two populations possesses the roughly identical death rate and the populations belong to the stable ones , while the survival curve of population in beiwenquan is concave , which shows that the population belongs to the increase one
2 、种群存活率曲线表明，鸡公山和东温泉的缙云卫矛种群存活率均呈对角线型，说明这两个种群属于稳定型，而北温泉种群的存活率曲线呈凹型，属于增长型种群。 - Base on the data collected from the field investigations , we analyzed the static life table , age structure , spatial distribution patterns of the populations of e . chloranthoides . we further studied the intraspecific competitions within the species and the interspecific competitions between the species and other concomitant species in the communities . with the helps of the logistic equation , leslie ' s matrix and the average moving law method we simulated and estimated the population dynamics of this endangered plant species
本研究以缙云卫矛为研究对象，通过对三个种群的野外调查，研究和分析了缙云卫矛的种群年龄结构、种群空间分布格局及种内和种间的竞争关系，并利用logistic方程、 leslie矩阵及移动平均法模拟和预测了三个种群的数量和结构动态，在此基础上分析了造成缙云卫矛濒危的原因，提出了相应的保护措施，旨在为缙云卫矛的保护提供理论依据。
