演替

The study is carried out that the comparison of fine root production, decomposition and distribution along with Korean pine and broad-leaved climax forest succession; the fine root contribution to the belowground C and N storage along with Korean pine and broad-leaved climax forest succession; and the comparison of belowground C and N storage among the Korean pine and broad-leaved climax forest, three dark-conifer forests, a betula ermanii forest along altitude.

研究内容包括：原始阔叶红松林及其不同演替阶段的次生林中细根的生长和周转、分解与分布的特征，阐明在不同演替阶段细根的变化；原始阔叶红松林及其不同演替阶段的次生林中细根对根系、土壤和林地地下的碳、氮贮量的影响，分析在不同演替阶段细根周转对地下碳、氮贮量的贡献；以及对不同垂直海拔高度分布的不同类型的原始森林中细根和根系生物量的变化，及细根对根系、土壤和林地地下碳、氮贮量的贡献进行了研究。

To study the effect of nematode-induced forest succession on avian communities, we chose three forest types at different seral stages, including evergreen broad-leaved coppice infested by the pine wood nematode for five years and evergreen broad-leaved forest infested for 12 years, both from Xiangshan County, Zhejiang, and one 40-year-old evergreen broad-leaved forest from Tiantong National Forest Park, Zhejiang.

为了探讨在松材线虫侵袭所引起的森林演替过程中植被结构变化对鸟类群落的影响，我们研究了这此常绿阔叶演替林中的鸟类群落结构。2004年5-6月，我们在浙江省宁波市选择了分别处于3个不同演替阶段的7个样地：包括象山县被松材线虫侵袭5年后的常绿阔叶灌丛和侵袭12年后的常绿阔叶林样地各3个，同时在天童国家级森林公园选择了约40龄的常绿阔叶林样地1个。

Based on the informative cluster analysis on succession of the plantation, the plant community in tidal zone can be classified into 4 categories: the primary types of plantation in succession is dominated by Saltliving Wormwood ; the climax in which Lalang Grass is the dominant, the seral community in which Chinese Aeluropus is the dominant; and the marsh community where reed is prevail.

通过信息聚类分析方法对滩涂的植物群落进行研究表明：滩涂植物群落可分为四种类型：以盐蒿为代表的演替初级阶段类型；以白茅为代表的演替高级阶段类型；以獐毛为代表的演替过渡阶段类型；以及以芦苇为代表的沼生植物类型。

The process of ecological succession in Dafeng County is the process of natural succession of 3 typical deposit-enlargement type seabeach.

大丰县生态演替过程是典型的淤长型滩涂的自然演替过程，人类活动的干予极大地促进了这一演替进程。

Also, during this process, the water content in vegetation increases and keeps stable gradually, and the water environment in ecosystem will become suavely.

摘 要：本文以南亚热带常绿阔叶林为基本，同时探讨了热带南亚热带森林演替系列中8种生态系统类型的水分结构，发现植被水分结构的恢复与土壤水分结构的恢复是不同步的，50a以上没有受扰动的土壤，其土壤水分结构在时空上才趋于稳定；植被水分结构的时空稳定性基本上与生态系统的演替状况一致；为满足植被蒸腾的需要，植被中水分的月更新次数随着群落向顶极系统的演替而逐渐减少。

The rule of ecological succession was studied in combined anaerobic process treating antibiotic wastewater. The structure and the metabolize model of granule sludge were founded primarily. The bionomic succession was a dynamic process, and would be developed in the perfect ways through control of bionomic factors and non-bionomic factors.

本文同时系统地研究了复合厌氧法处理抗生素废水的微生物群落演替规律，初步建立了处理抗生素废水的复合厌氧反应器中颗粒污泥的代谢模型，并指出，微生物的群落演替是动态的，通过对生态因子和非生态因子的人为调控，可以使演替按照理想的方向发展。

Clisere A succession of climax communities in given area, each giving way to the next as a result of climatic changes.

气候演替系列：在一定区域内的顶级群落的演替。作为气候变化的结果，每个演替为下一个演替作好准备。

Degradative succession is a type of augogenic succession involving colonization and subsequent decomposition of dead organic matter.

退行性演替退行性演替是涉及到移殖和死亡有机体后来腐烂分解的自发演替的一种类型。

Stages in a secondary succession, which appear when the biotic components of a primary sere are destroyed, e.g. by fire, are called subseres; seres in microhabitats are called microseres.

次级演替群体出现于初级演替群体的生物组分发生一定程度的破坏后，例如：火灾造成次生演替系列；微生态改变造成微演替系列。

Three types of empty-shell marriages have been identified. In a devitalized relationship husband and wife lack excitement or any real interest in their spouse or their marriage.

一种是死气沉沉的婚姻：在这种婚姻关系中夫妻俩对于配偶或婚姻缺乏激情，或者缺乏真正的兴趣。
