Species richness and Pielou evenness index were used to measure species diversity. Species richness in polluted area was 32-67, while in control area it was 47-82. Pielou evenness index of tree layer was 0.1161-0.8509, while those of shrub layer and herb layer were 0.1763-0.3249 and 0.0443-0.2601, respectively. The results showed that both species richness and Pielou evenness index were influenced by the point source pollution. Species importance values showed significant differences between polluted area and control area. Dominance of different species had changed, and some species even disappeared under the pressure of pollution, indicating a process of species replacement in plant communities. Such species replacement can provide a scientific basis for species selection for restoration of human-damaged ecosystem. The natural regeneration of Quercus variabilis was insensitive to pollution, while Cupressus funebris was effected seriously.

仅在污染区中出现的物种数量远低于仅在对照区中出现的物种数量;(2)可分出4种基本的群落类型:马尾松林、柏木林、栓皮栎林和马尾松+栓皮栎林,各群落特定层次的物种丰富度指数以及Pielou均匀度指数在污染区与对照区之间存在显著差异;(3)污染胁迫下,物种在群落中的生态优势度发生了变化,反映了群落中不同物种相互替代的过程,这种物种的替代可为今后受损生态系统人为恢复过程中物种的筛选提供一定的理论参考;(4)对群落中王要物种更新的调查发现:栓皮栎林对污染不敏感;柏木林污染区与对照区幼苗数量及分布格局均有明显差异,污染条件下群落未来演替受到严重干扰。

--- Disclosed are a process and plant for the recovery of water from humid air, in which at night cool humid air is passed through an adsorbent medium layer which adsorbs water from the air and in which, by day, air heated by solar energy up to a temperature which is above the ambient temperature is passed first through this layer to absorb water from the layer and then is cooled down so that the water condenses.

摘要---透露,是一个过程和植物为香港经济复苏的水从潮湿空气,在这种在夜间凉爽潮湿的空气是通过一吸附剂的介质层,其中吸附的水,从空中和在其中,由天,空气加热太阳能能源最多的温度是高于环境温度是通过第一,通过这层吸收水层,然后是冷却下来,使水凝结。

A process for partial conversion and low-temp transform of CO in the synthetic ammonia plant where coal is used to generate gas features that the Fe-Mo catalyst for partial conversion of CO, anti-poisoning agent and Co-Mo catalyst for low-temp conversion are used and the temp of semi-water gas is controlled to 200-260 deg.C at entering anti-poisoning layer, and 150-250 deg.C at the segments of said Co-Mo catalyst layer, and lower than 300 deg.C at bed layer to prevent high-temp reversal of sulfurizing reaction and make the catalyst activity optimal. Its advantages are long service life of catalyst, low system resistance, saving energy and convenient operation.

本发明是中小合成氨厂以一种CO部分转化抗毒保护层配低温变换的工艺,涉及煤造气合成氨厂0.6~2.0MPa半水煤气变换工艺流程,该工艺用铁-钼CO部分转化催化剂、抗毒剂,配钴-钼低变催化剂,半水煤气进入部分转化抗毒层温度为200~260℃,进钴-钼低变催化剂各段温度为150~250℃,床层温度控制在300℃以内,避免高温下反硫化反应发生,保护催化剂活性处最佳状态,寿命延长、系统阻力小、节汽、节电,具有比其他变换工艺更好地节能效果,操作方便,有效生产时间长,经济效益显著等特点。
