Examples
- It is a good place for both serious hill walkers and families . natural bushes bloom on the hills and in the valleys
公园内山丘上及山谷中天然灌木茂密，在冬天开花的有大头茶，而在春天则有杜鹃。 - Based on the theory of gradient transport , we analysed the different turbulence dispersal situation of pollen and seeds and bring about the turbulence dispersal model of pollen and seeds . finally , we used this model studied the seeds dispersal pattern of gordonia acumenata , the dominant species of evergreen broableaved forest
运用梯度输送理论分析了植物花粉、种子湍流扩散的不同情况,导出了植物花粉、种子散布的湍流扩散模型,并运用此模型研究了亚热带常绿阔叶林优势种四川大头茶的种子散布格局 - Niche breadth of four dominate populations at three age groups was studied by the methods of resource utilization ability and ratio . the result shows that : symplocos sectchuanensis is a typical gengeration species whi ch resource utilization ability is strong , and distribution is wide . meanwhile , go rdonia acuminata , castanopsis fargesis and pinus massoniana specialized at some d egree in resource utilizationm , their distribution is limited . especially , the ju venile of pinus massoniana specialized outstandingly . with the devlopment of pinu s massoniana , which is the pioneer population in mt . jinyun , the environment become s unfit to it ' s juvenile . it turns to needle and evergreen broad - leaves mixed fo r est . because the tolerance toward shading of gordonia acuminata is lower than tha t of castanopsis fargesis , gordonia acuminata will be substituted by castanopsis fargesis and other evergreen broad - leaves species are the edificators . the popul ation ' s ability of resource utilization is the inner factor of population distri bution and community succession . the distribution of light and the concentrate of nutrient ( such as n ) is the outer factors of community succession
对缙云山森林植被的4个优势种群3个年龄级生态位宽度进行了研究.结果表明，川灰木利用资源的能力最强、分布广，为典型的泛化种.大头茶、栲树、马尾松对资源的利用在一定程度上特化，分布上有一定的局限性.马尾松的中龄组与幼龄组特化现象十分显著.缙云山森林植被的先锋种马尾松的发展，导致环境的改变不适于其幼龄个体的生长，群落演替到针阔叶混交林阶段，最后发展为以栲树等为建群种的常绿阔叶林.种群的资源利用能力，是种群分布与群落演替的内在原因，光因子和营养元素(如n )是群落演替的主要外部动力 - The paper studies on two different vegetation type areas in jingyun mountain in chongqing city , which are broadleaved forests ( gordinya svchuanensvs ) and bamboo ( phyllostachys edulis ) forests . by contrasting the surface runoff and underground runoff in these two areas , the results showed that , with the same precipitation , the gross amount of runoff in bamboo forests was larger than that in broadleaved forests and the runoff in bamboo forests appeared before that in broadleaved forests . the amount of underground runoff was larger than that of surface runoff in the two areas , the process of surface runoff was in accordance with that of underground runoff
该文以重庆市缙云山的两个不同植被类型常绿阔叶林(四川大头茶)和楠竹林小区为研究对象,对小区中典型降雨后的地表径流、地下径流的实测资料进行对比分析.结果发现在相同降雨条件下,楠竹林的地表径流量与地下径流量明显要比常绿阔叶林的大,楠竹林地表径流和地下径流出现的时间也比常绿阔叶林早;两种植被的地表径流与地下径流过程具有一定的相似性,地下径流量都比地表径流量大
