clima

A continuous-flow fermentation reactor in bench scale was used to study the structure and dominant composition, as well as ecological succession of climax community restricted by factors such as pH, ORP.

通过产酸发酵反应器的动态试验 ,考察生态因子 (pH、ORP)等制约的不同发酵类型顶极群落的结构、优势种群的组成和生态演替的规律 ,阐明不同发酵类型代谢及其顶极群落的典型特征 ,揭示产酸发酵过程中顶极群落内平衡与反馈调节的生理代谢机制 ,并以 pH值、ORP来表征生态演替过程中优势种群的生态位

To bring“ wetland” advantage into full play by establishing“ green kidney” which is as important as“ green lung”； set up green“ time channel” by using pluralistic“ cultural meaning” of green space； realize the goal of“ introducing nature into city” with the ecological theory“ climax community”； use the existing laws and regulations on the guaranty of raising the green space to a new stage.

为迎接新世纪的到来，上海要创建具有地方特色的绿色空间，应充分发挥“湿地”优势，建成与“绿肺”同等重要的“绿肾”；运用多元化“文化内涵”的绿色空间优势建成绿色“时间通道”；依照生态学的“顶极群落”理论实施“把自然引入城市”的计划；用好已有的法律法规是绿色空间上新台阶的保证。

It was shown that the sand-fixing vegetation established before 1960 had reached its subclimax.

对腾格里沙漠沙坡头人工固沙区草本植物带群落的结构组成进行了分析，结果表明，６０年代以前的固沙植被区已进入演替的亚顶极群落，群落多样性、均匀度值均达相对最大，优势度最低。
