发现这部分比较麻烦,所以开放一个单独的issue.

我把相关的论文放在这里了,大部分论文读起来像小说一样,没啥公式的。


一些要点:

生态改造的目标 (来自:Planetary Engineering By Pollack and Sagan

植物的要求

参数 范围 备注
全球气温 0-30摄氏度 地球的全球平均气温 15 摄氏度
气压 >10mbar (植物的要求)O2,N2, CO2 合压
CO2 >0.15mbar 光合作用的要求
N2 1-10 mbar 氮合成
O2 >1 mbar 植物的呼吸作用

人类的要求

参数 范围 备注
人类呼吸的总压强 >250 mbar 肺中的水汽,CO2,O2
CO2 <10 mbar CO2 毒性
N2 >300 mbar 缓冲气体(??)
O2 >130 mbar 并且 <300 mbar 上限考虑组织缺氧的问题,下限考虑燃烧的问题

一篇新文:
http://arxiv.org/abs/1507.05495

干货不多,但是主要的思路是由于目前地球是小冰盖时期,这在气候上是个不稳定脆弱的系统,而通过改造使其成为大冰盖的话,由于返照律上升,地球气候对于各种地面活动会更稳定。

但是改造计划实施持续时间太久…中间不能中断…
