In the course of reform china, the structure of community governance begins to form . but the community governance failure appears 改革以来,中国在社区建设中初步实现了由管理向治理的转型,但“社区治理失灵”现象大量存在。
First, a summary is made about recent chinese study on bird community . the study mainly focuses on two aspects : the structure of community and guild 论文首先对中国鸟类群落的研究进行了简要回顾,群落结构和种团是研究的两个重要部分。
Whereas, for the natural forest consisted of native species, the niche overlap was low and the interspecies relationship was harmonious . the composition structure of community thereby was more stable 而由本地树种组成的天然林,生态位重叠小,种间关系协调,群落组成结构的稳定性更高。
Based on the foundation of soft quality attribute, by analyze the constitute and structure of community space, and build up the correlation among the community with trafic and afforest 在对交往软质属性建立的基础上,本文通过探讨分析交往空间的构成,结构及与居住区交通、绿化系统属性的关系,尝试建立居住小区中交往空间的系统性研究体系。
Iii ) for artificial communities including herbaceous community, pure conifer and needle broad-leaved mixed forest, the poor niche configuration and serious niche overlap of component species made the composition structure of community be in an unstable state 3)人工构建的群落(包括草本群落、针叶纯林和针阔混交林)其组成物种生态位配置差,生态位重叠大,造成群落组成结构不稳定。
This group of plants is widely distributed all over the world in a wide variety of species, and they therefore, have a significant effect on the appearance and structure of community, particularly on those of tropical and subtropical regions . many species possess significant economic value, however, some of them can also severely endanger the forest community, agricultural crops and other plant life 这类植物在世界范围内分布广泛,种类繁多,对群落的外貌和结构特别是热带、亚热带森林群落的外貌和结构有重要影响;其中许多种类具有重要的经济价值,但也有些种类严重危害森林群落、农作物等。
In original and jamming slightly vegetation, because dead roots, branch and leaves back to soil, soil organic matter higher, soil available phosphorus higher, too; chemical and physical characters of soil were stabilization . the reason were original vegetation have more species and structure of community was stable . the degradation of fertility and structure of soil in secondary vegetation was influenced by change with structure and form of community 在人为干扰小的原生性森林,植物种类丰富,群落结构稳定,植物死根系和枯枝落叶全部回归土壤,土壤有机质含量高,养分呈有机态为多,故有效磷较高,土壤理化性质较稳定;次生植被群落土壤结构和肥力的退化是由于群落组成和结构的改变导致枯枝落叶成分和土壤发规白山地还小问沙消民俗一非定俗地征王卿乔忡旺w比收财育环境差异而引起,次生植被土壤的退化状态随植被退化程度不同而有差异。
