Study on the population structure and life table of the endangered population of juniperus rigida in fugu nature reserve in shaanxi province

CHU Sheng-Li1,LI Deng-Wu2,LI Jing-Xia2(1.College of Life Sciences,Northwest A&F University,Yangling 712100,China;2.College of Forestry,Northwest A&F University,Yangling 712100,China)  
In order to characterize the age structure and dynamics of the Juniperus rigida population so as to better conserve its resources,the static life table,the curves of survivorship,mortality rate of the population were drawn.The results showed that the numbers of Juniperus rigida population was very limited.The population is of declining type.Its survival curve could be left-skewed type.The discipline of mortality ratio showed the similar dynamics to that of the hazard ratio.The mortality rates and hazard rates at age class Ⅰ and age class Ⅱ were negative,and the highest points appeared at age class Ⅵ.The key cause for population decline was that shade in the forest obstructed germination,seedling growth and human disturbance.The best way to protect the rare plant is that increasing the number of seedlings and decreasing the human disturbance.
